Guide to using beer enhancer (DME / LME) to improve homebrew beer 'mouth feel'

Beer enhancers are specially formulated additives that serve to improve the overall quality of homebrewed beer. Unlike traditional sugar additions, which can lead to a thinner taste and feel, enhancers are designed to complement the malt flavors and boost the body of the beer. 

Typically, these enhancers are a blend of simple and complex sugars, proteins, and sometimes flavor elements. Their composition is carefully balanced to support the fermentation process, encouraging a more nuanced flavor profile and a richer mouthfeel.

The Role of Beer Enhancers in Homebrewing

One of the primary benefits of using beer enhancers is the significant impact they have on the taste of the beer. By providing a mix of fermentable and unfermentable components, enhancers contribute to a more complex and rounded flavor. During fermentation, the yeast consumes the fermentable sugars, producing alcohol and carbon dioxide, while the unfermentable parts remain, adding depth and character to the beer. '

This complexity is something that cannot be achieved with regular sugar alone. Indeed, in the 'old days' people would use extra sugar and beers would come out too 'dry' in the classic bad brew sense that gave homebrewed beer a poor reputation. 

But we all know better these days eh?

Mouthfeel refers to the physical sensations experienced when drinking beer, encompassing attributes like body, creaminess, and carbonation. Enhancers often contain ingredients like maltodextrin, which is not fermented by the yeast, thereby increasing the viscosity and giving the beer a fuller body. This results in a smoother and more satisfying drinking experience, akin to what is found in professionally brewed beers.

Achieving a consistent brew can be challenging for homebrewers, but beer enhancers offer a solution. By standardizing the addition of certain elements, brewers can more reliably produce beer with the same flavor profile and carbonation levels batch after batch. Furthermore, the improved stability provided by enhancers means that the beer maintains its quality over time, reducing the risk of off-flavors developing.

Types of Beer Enhancers for improved mouthfeel

Beer enhancers come in various formulations, each designed to cater to different brewing needs and preferences. 

The main ingredients typically include:

Dry Malt Extract (DME) is a concentrated form of malt extract that provides fermentable sugars essential for the brewing process. It offers brewers a convenient way to add malt flavor to their beer without the need for mashing or lautering. DME enhances the malt character of the brew, contributing to its complexity and depth of flavor. 

Unlike liquid malt extract (LME), DME has a longer shelf life and is easier to store, making it a preferred choice for many homebrewers. It's particularly useful in recipes where precise control over fermentable sugars is desired, as it allows for consistent results batch after batch. Additionally, DME is known for its ability to boost the beer's alcohol content without adding excessive sweetness, making it a versatile ingredient in various beer styles.

Maltodextrin, on the other hand, is a polysaccharide derived from starch, commonly corn or wheat. Unlike fermentable sugars such as those found in DME or LME, maltodextrin is non-fermentable, meaning it does not contribute to alcohol production during fermentation. Instead, it serves primarily to enhance the mouthfeel and body of the beer, providing a smoother, fuller texture without increasing the brew's alcoholic strength. Brewers often use maltodextrin to improve the body and perceived sweetness of low-alcohol or light-bodied beers, such as session ales or lagers. 

Specialty grains encompass a wide range of malted and unmalted grains used in brewing to add unique flavors, colors, and aromas to beer. These grains include but are not limited to caramel/crystal malts, roasted malts, chocolate malt, and flaked grains like oats or wheat.

Specialty grains are typically steeped or mashed during the brewing process to extract their flavors and colors before the wort is boiled. They play a crucial role in shaping the character and complexity of the final beer, allowing brewers to create a wide variety of styles and flavor profiles. 

Practical Application: Adding Enhancers to Your Brew

Enhancers are typically added during the boiling phase of the brewing process. This allows for the ingredients to be fully integrated into the wort, ensuring even distribution and optimal utilization by the yeast during fermentation. The timing and method of addition can vary slightly depending on the specific enhancer and the brewer's recipe.

The amount of enhancer needed will depend on the volume of the brew and the specific gravity targets. It's crucial to measure accurately and adjust based on taste tests and gravity readings. 

Typically brew enhancers come in a 1 Kg size which complements a 20 litre batch of wort.

The Enzymatic Powerhouse of Beer Brewing: Amylase

Beer brewing is an alchemy of science and tradition, where the transformation of basic ingredients into a complex and enjoyable beverage relies on a series of biochemical reactions. Among the myriad components and processes involved, the role of enzymes, particularly amylase, is fundamental.

The Biological Significance of Enzymes

Before diving into the specifics of amylase in brewing, it's essential to understand the broader context of enzymes in biology. Enzymes are proteins that act as catalysts in living organisms, speeding up and facilitating chemical reactions that are vital for life. Amylase, like lipase, is crucial in human metabolism, playing a key role in digestion, starting right in the mouth where it begins breaking down starches into simpler sugars.

Amylase: The Star of Beer Brewing

In the context of brewing, amylase is indispensable. This enzyme is responsible for converting the starches found in malted grains into soluble sugars. These sugars are the primary food source for yeast during fermentation, ultimately producing alcohol and carbon dioxide. Understanding the functionality of amylase allows brewers to manipulate the fermentability of their wort, thereby crafting beers with specific desired characteristics.

The Mashing Process: Where Amylase Takes Center Stage

Starch Conversion and Fermentable Sugars

The mashing process in brewing is where amylase's role is most pronounced. Mashing involves mixing milled grains with water, creating a conducive environment for amylase to break down the grain's starches into fermentable sugars. This conversion is critical, as the type and amount of sugars produced directly affect the beer's final alcohol content, body, and flavor profile.

Alpha and Beta Amylase: A Synergistic Duo

Within the mash, two types of amylase work in tandem: alpha-amylase and beta-amylase. Alpha-amylase randomly attacks the internal bonds of starch chains, creating a range of sugar molecules of different sizes. Beta-amylase then processes these chains further, primarily producing maltose, along with glucose and maltotriose. This complementary action ensures the efficient breakdown of starches into a spectrum of sugars suitable for fermentation.

The Science of Amylase Action

Temperature and Enzymatic Activity

The activity of amylase is highly sensitive to temperature. The ideal temperature range for amylase in brewing is between 150-155°F (65-68°C). Exceeding this range can denature the enzyme, rendering it ineffective. Conversely, lower temperatures may not activate the enzyme sufficiently. Maintaining the right temperature during mashing is crucial for optimal starch conversion.

The pH Factor in Enzyme Efficiency

The pH level of the mash also significantly impacts enzyme activity. A slightly acidic environment, typically around pH 5.2-5.6, is optimal for amylase.

Deviations from this range can hinder enzyme efficiency, affecting both the conversion of starches and the overall brewing process, including hop utilization and yeast fermentation. Use a quality pH meter to test your wort's pH levels.

Strategic Use of Amylase in Brewing

Timing and Technique

The addition of amylase to the mash is a carefully timed process. Brewers may introduce the enzyme either at the beginning of the mash or partway through, depending on the desired outcome. Controlling the temperature and pH during this stage is vital for achieving complete starch conversion before the wort is cooled down for fermentation.

Impact on Beer Characteristics

Temperature control during mashing plays a dual role. Lower temperatures tend to favor higher alcohol content, as more fermentable sugars are available for yeast consumption. In contrast, higher temperatures result in a fuller mouthfeel, due to the presence of unfermentable sugars. These nuances allow brewers to tailor the body and strength of their beer.

Beyond the Mash: Flavor Implications

There's a debate among brewers about whether amylase directly affects the taste of beer. While its primary role is in starch breakdown, subtle variations in the mashing process can lead to different flavor nuances. These can contribute to the complexity of the beer's taste profile, adding depth and character to the final product.

Conclusion

The mastery of amylase use in brewing is a fine balance of science and art. It requires not only a deep understanding of biochemical processes but also a nuanced approach to creating the desired beer profile. From pH levels to precise temperature control, every detail counts in the quest for the perfect pint. Armed with this knowledge, brewers can experiment and innovate, pushing the boundaries of traditional brewing methods to craft unique and memorable beers.

Why are adjuncts added to beer wort home brewing?

Adjuncts in brewing are the wildcards, the renegades that break away from the sacred four—water, malted barley, hops, and yeast. They're the brewers' secret weapons, adding layers of complexity to a beer’s flavor, aroma, body, and color. 

Far from being confined to the standard, adjuncts open the door to a vast spectrum of possibilities: alternative grains, sugars, fruits, spices, and herbs—all fair game.

These additions are more than just flavor tweaks; they represent a brewer's willingness to push boundaries, to experiment, to take beer beyond tradition and into new, uncharted territories.

Their usage marks a departure from the purity laws like the Reinheitsgebot, a historic German beer purity law, and opens up a world of creative possibilities in brewing. The use of adjuncts is not a new practice; it has evolved over centuries and varies significantly across different brewing cultures and beer styles.

Historical Context of Adjunct Usage

The history of adjunct usage in brewing is as rich and diverse as the ingredients themselves. Historically, adjuncts have been used for various reasons, including cost reduction, availability, and the desire to create unique flavor profiles. 

In some regions, the availability of traditional ingredients was limited or expensive, leading brewers to experiment with locally available alternatives. For instance, corn and rice became popular adjuncts in American lager brewing in the 19th century due to their abundance and cost-effectiveness compared to barley.

The use of adjuncts has often been influenced by cultural and economic factors. During times of scarcity or war, brewers were forced to be resourceful, using whatever ingredients were at hand. In other instances, the introduction of new ingredients from foreign lands spurred innovation and experimentation in brewing. 

The evolution of adjunct usage reflects not only the ingenuity and adaptability of brewers but also the shifting tastes and preferences of beer drinkers over time.

Types of Adjuncts that can be added to beer wort

Adjuncts in brewing can be broadly categorized based on their source and characteristics. Common types of adjuncts include:

• Grains: Other than barley, various grains such as corn, rice, wheat, rye, and oats are used in brewing. Each grain imparts its unique characteristics to the beer. For example, corn adds a mild, sweet flavor and can lighten the body of the beer, while oats contribute to a smoother mouthfeel.
• Sugars: Sugars like honey, molasses, and various forms of syrup can be added to influence the beer's sweetness, color, and alcohol content. These sugars can also impact fermentation dynamics and the final gravity of the beer.
• Fruits: Fruits, both fresh and dried, are used to add natural sweetness and a spectrum of fruity flavors. From the subtle citrus notes of orange peel to the bold tartness of cherries, fruits can significantly alter a beer's flavor profile.
• Spices and Herbs: Spices such as coriander, cinnamon, and cloves, as well as herbs like lavender and thyme, are used to introduce complex aromas and flavors. These ingredients are often key in defining certain beer styles, such as Belgian witbiers or spiced winter ales.

The choice of adjuncts and their use in brewing is guided by the desired characteristics in the final beer. 

Flavor and Aroma Contributions

Adjuncts play a crucial role in shaping the flavor and aroma profiles of beer. Each adjunct brings its unique sensory attributes, allowing brewers to craft a diverse range of beers with distinct characteristics. For instance, the addition of fruits like raspberries or mango can introduce fresh, tangy flavors and vibrant aromas, creating a fruit-forward beer experience. 

On the other hand, the use of spices such as cinnamon or vanilla can impart warm, spicy notes, ideal for creating rich, complex winter ales.

Grains such as wheat or rye contribute to the beer's flavor profile in more subtle ways. Wheat often adds a light, slightly citrusy flavor, ideal for refreshing summer beers, while rye can impart a spicy, earthy note, adding depth to darker ales or specialty beers. Sugars, like Belgian candi sugar, not only affect the sweetness and alcohol content but also contribute to the overall flavor profile, often adding caramel or toffee notes.

Impact on Beer Body and Mouthfeel

Beyond flavor and aroma, adjuncts significantly influence the beer's body and mouthfeel. The body of a beer refers to its weight and fullness on the palate, ranging from light and refreshing to rich and full-bodied. Mouthfeel, on the other hand, describes the tactile sensations experienced while drinking, such as creaminess, crispness, or astringency. Adjuncts can be strategically used to manipulate these sensory aspects.

Grains like oats and wheat are known for enhancing the mouthfeel of beer. Oats, in particular, are often used in stouts and porters to impart a silky, smooth texture. The use of certain sugars can also impact the body, either by increasing the beer's density or by fermenting fully and creating a drier, lighter beer.

Conversely, some adjuncts can have a thinning effect on the beer's body. For example, the use of rice or corn in brewing can lead to a lighter, more crisp beer, which is a characteristic sought after in many lager styles. The choice and amount of adjuncts used can be a delicate balancing act, ensuring that the desired body and mouthfeel are achieved without compromising the beer's overall harmony.

Economic and Practical Considerations

The use of adjuncts in beer brewing is often influenced by economic and practical considerations. One primary factor is cost. Adjuncts like corn and rice are sometimes used as cheaper alternatives to barley, especially in large-scale brewing operations. This cost-saving measure can be crucial in competitive markets where price sensitivity is high.

In addition to cost, the availability of ingredients plays a significant role. Local availability of certain adjuncts can inspire brewers to experiment with regional flavors, creating beers that reflect the local character and tradition. For example, the use of locally sourced honey or fruits can not only reduce costs but also add a unique, location-specific dimension to the beer.

From a practical standpoint, adjuncts can impact the brewing process itself. Some adjuncts might require special handling or equipment, such as additional milling or specific temperature control during mashing. 

The fermentation characteristics of certain sugars or the incorporation of fruits and spices also demand careful consideration to ensure a consistent and quality product.

Creativity and Innovation in Brewing

Adjuncts offer brewers a canvas for creativity and innovation. The incorporation of non-traditional ingredients allows for the exploration of new flavors, textures, and aromas, pushing the boundaries of conventional beer styles. This creative use of adjuncts has led to the emergence of new beer styles and the reinterpretation of classic ones. For instance, the addition of coffee or chocolate to stouts has given rise to rich, dessert-like beers, while the use of exotic fruits in IPAs has created a new wave of fruit-infused hoppy beers.

Innovation with adjuncts is not limited to flavors alone; it also involves experimenting with brewing techniques and ingredient combinations. Brewers might age beers on different woods, use unconventional fermentation methods, or blend various adjuncts to achieve unique results. These innovations reflect the dynamic nature of the brewing industry and the continual quest for differentiation and excellence.

Isn't it good, Norwegian wood?

Adjuncts in Different Beer Styles

The role of adjuncts varies widely across different beer styles. In some styles, the use of adjuncts is integral to the beer's identity, while in others, it is more about subtle enhancements. For example, in Belgian witbiers, the use of orange peel and coriander is essential to achieving the style's characteristic citrusy and spicy profile. 

In contrast, the addition of rye in an IPA might be aimed at adding a subtle layer of complexity to the beer's overall flavor.

The traditional use of adjuncts in certain styles often reflects historical or regional influences. However, modern brewing has seen a departure from these traditions, with brewers experimenting with adjuncts in unexpected ways. This blending of traditional and modern approaches has led to a rich diversity in beer styles and flavors, offering beer enthusiasts a wide range of experiences.

Sustainability and Environmental Impact

Sustainability and environmental impact are increasingly important considerations in the use of adjuncts in brewing. 

Brewers are looking at ways to minimize their environmental footprint by choosing locally sourced, organic, or sustainably produced adjuncts. The use of local ingredients not only supports local economies but also reduces transportation emissions.

Sustainability in brewing also involves the efficient use of resources and the reduction of waste. Some breweries are finding innovative ways to repurpose spent grains or other by-products of the brewing process. 

The use of adjuncts can be part of a broader strategy to create more sustainable and environmentally friendly brewing practices.

Conclusion: The Balancing Act of Adjunct Use

The use of adjuncts in brewing is a balancing act between tradition and innovation, flavor and practicality, creativity and sustainability. While adjuncts offer brewers the opportunity to expand their artistic palette, they also bring challenges in terms of production, consistency, and environmental impact. The successful use of adjuncts requires a deep understanding of both the ingredients and the brewing process, as well as a thoughtful consideration of the beer's intended character and the brewer's goals.

In the end, adjuncts are a testament to the ever-evolving nature of brewing and the endless possibilities for creating unique and memorable beers. Whether enhancing traditional styles or forging new ones, adjuncts play a pivotal role in the rich tapestry of the brewing world.

Reinheitsgebot: Germany's 500-Year-Old Beer Purity Law

The Reinheitsgebot, often translated as the "Beer Purity Law," is a historic regulation that has left an indelible mark on the world of brewing. Dating back to 1516, it was instituted in the Duchy of Bavaria with the primary aim of ensuring the quality and purity of beer produced in the region, ultimately protecting consumers from potential contaminants or harmful additives.

In this article, we will delve deep into the origins, ingredients, controversies, and modern implications of this 500-year-old beer purity law.

Origins of the Reinheitsgebot

The Reinheitsgebot's roots can be traced back to the Duchy of Bavaria in the 16th century. At its core, this law dictated the permissible ingredients for brewing beer. These ingredients were carefully selected to maintain the quality and integrity of the beer produced.

The Three Permitted Ingredients

1. Water: Water is the primary component of beer and plays a fundamental role in the brewing process. The quality of water used directly influences the final product's taste and characteristics.

2. Barley: Barley was chosen as the exclusive grain for its fermentable sugars, which are crucial for alcohol production. The Reinheitsgebot mandated that only barley be used, further emphasizing the commitment to purity.

3. Hops: Hops were added for their flavor, aroma, and preservation qualities. They not only contributed to the unique taste of beer but also helped extend its shelf life.

It's important to note that yeast was not originally included in the Reinheitsgebot because its role in fermentation was not fully understood at the time. However, as the understanding of fermentation evolved, yeast was eventually recognized as an essential ingredient and incorporated into the list of permissible components.

Controversies Surrounding the Reinheitsgebot

While the Reinheitsgebot was introduced with the noble intention of ensuring beer purity, its implementation was not without its share of controversies.

The economic motivations behind the Reinheitsgebot, often shrouded in historical intricacies, reveal a complex interplay between brewing, baking, and the broader grain market. As we delve deeper into this facet of the law's history, it becomes evident that its primary goal extended beyond merely ensuring the purity of beer; it encompassed a comprehensive strategy to shape the economic landscape of the Duchy of Bavaria.

Competition and Grain Utilization In the 16th century, both brewing and baking were essential industries, deeply intertwined with the daily lives of Bavarian citizens. Brewers and bakers were equally reliant on grains, albeit different types. Brewers predominantly used barley as the primary grain for brewing beer, while bakers heavily depended on wheat and rye for bread production. This divergence in grain usage naturally led to competition for the same resources within the grain market.

Price Stability and Market Control The Reinheitsgebot addressed this competition by limiting the types of grains that could be used in brewing. By exclusively permitting barley as the grain for brewing beer, the law effectively reserved the higher-priced grains like wheat and rye for bakers. This strategic allocation of grains aimed to achieve several economic objectives.

1. Price Stability: By ensuring that barley was the primary grain used in brewing, the law sought to stabilize grain prices. Since barley was not in direct competition with wheat and rye, it helped prevent fluctuations in the cost of these essential grains.

2. Market Control: The Reinheitsgebot effectively placed control over the grain market in the hands of the ruling elite and those involved in brewing. This centralization of authority allowed for better regulation and, from the perspective of those in power, a more predictable and manageable grain market.

Impact on Competition and Quality While the economic motivations of the Reinheitsgebot were apparent, they did not come without their share of consequences. The law's emphasis on barley in brewing effectively eliminated competition from other grains, potentially limiting the diversity of beer styles that could have emerged from using alternative grains.

Moreover, the law's strict enforcement meant that brewers who failed to adhere to its standards faced penalties, including confiscation of their beer.

Exclusion of Other Beverages

The Reinheitsgebot, with its strict regulations on the ingredients allowed in brewing, extended its influence beyond the realm of beer, causing significant debate and controversy in its wake. This aspect of the law, which excluded other alcoholic beverages from its purview in the Duchy of Bavaria, raises intriguing questions about the law's broader intentions and its potential to centralize power among the ruling elite.

A Narrow Focus on Beer The Reinheitsgebot, as its name suggests, was primarily concerned with the purity and quality of beer. It meticulously detailed the permissible ingredients for brewing beer, as we've explored in previous sections. However, this focus on beer exclusivity created a distinct divide within the alcoholic beverage industry.

Gruit Beer and Herbal Brews One notable casualty of the Reinheitsgebot was the exclusion of gruit beer and other herbal brews from the market. Gruit beer, in particular, was a unique and popular beverage in its own right. Unlike traditional beer, gruit beer was flavored with a mixture of herbs, often including ingredients such as sweet gale, yarrow, and juniper berries. These herbs imparted distinctive flavors and characteristics to the brew, setting it apart from conventional beer.

Centralization of Brewing The exclusion of gruit beer and similar herbal brews led some to speculate about the Reinheitsgebot's broader motives. Critics argued that this exclusion served as a means to centralize brewing activities in the region, effectively consolidating power among the ruling elite. By limiting the variety of alcoholic beverages available and promoting the uniformity of beer, those in authority could exercise greater control over the brewing industry.

Economic and Political Implications The exclusion of herbal brews not only impacted consumer choice but also had economic and political implications. It curtailed the livelihoods of those involved in the production and trade of gruit beer and similar beverages, potentially concentrating wealth and influence in the hands of the beer brewers who could comply with the Reinheitsgebot.

Cultural and Historical Significance Beyond the economic and political aspects, the exclusion of other beverages highlighted the cultural and historical significance of the Reinheitsgebot. It became more than just a set of regulations; it symbolized a shift in brewing traditions and preferences within Bavaria.

Modern Implications

The controversies surrounding the Reinheitsgebot did not end in the 16th century. In the modern era, it has faced criticism from craft brewers and beer enthusiasts who view it as a limitation on creativity and innovation in brewing. They argue that the law restricts the diversity of beer flavors and styles available in the market.

However, many German brewers continue to take pride in the Reinheitsgebot, seeing it as a mark of quality and tradition. For them, brewing within the constraints of the law is a testament to their skill and the rich heritage of German beer.

In conclusion, the Reinheitsgebot, or the German Beer Purity Law of 1516, has a complex and enduring legacy. While it was introduced with the intent of standardizing beer quality and protecting consumers, its economic, social, and political implications have made it a topic of debate and controversy for over 500 years.
