Mastering Malted Barley: Essential Insights for Brewers
Making beer is like whipping up your favorite dish, and just like every dish, there are key ingredients. Over the years, barley has been recognized as a crucial ingredient in beer brewing; brewing beer without barley is like making wine without grapes.
In this guide, we'll take a deep dive into the world of malted barley, exploring what it is, how it's made, the different varieties available, and how it affects the flavor and aroma of your beer.
What Is Malting, And Why Is It Important in Beer?
Malting is the process of turning raw barley grains into malt, which is then utilized to make beer. The barley grain is soaked in water during the malting process and allowed to germinate or sprout. This process kickstarts the activation of the grain's enzymes, which are essential for converting starches into fermentable sugars during the brewing process.
Malting Process
The malting process consists of several stages that are essential for the production of beer. The process begins with the selection of high-quality, impurity-free barley grains. The brewing process of malting happens in three stages:
Steeping
The process of steeping begins by soaking the barley in water and allowing it to absorb moisture. After a few hours, the water is drained, and the grain is exposed to air. It passes through several stages of humidification and oxygenation (to activate the embryo). Steeping lasts a few days and ends once the grain moisture content rises to an average of 45 percent.
Germinating
Once steeping is done, it's time for germination. During germination, the barley is soaked in water for a period, allowing the grains to swell and the enzymes to become active. This process converts the barley's starches into sugars that can be used for brewing. The germination process typically takes between 3-5 days, depending on the type of barley and the environment.
Kilning
The kilning process begins with the germinated barley being spread out in a kiln and heated to a specific temperature. Kilning is important because it can impact the barley's color and flavor and stop the seed from growing into a plant.
The heat helps to dry out the barley, and it also helps to break down the starches into simpler sugars, which can then be used by the yeast during the fermentation process.
What Is Malted Barley?
Barley is a cereal grain, much like wheat and corn. Just like barley, you can malt any grain. For corn, it becomes malted corn, and the same goes for wheat. Malted barley, therefore, is a grain that has been processed through the malting process.
The malting process enhances the grain's flavor, aroma, and color. It also breaks down the starches in the grain, making them more accessible for fermentation.
Shapes Of Barley
Barley is available in two-row and six-row varieties, as well as winter two-row and winter six-row. Each variety has unique characteristics that can affect the beer’s flavor, aroma, and color.
Two-Row
Two-row barley is one of the most popular types of malted barley used in brewing. Two-row barley is a type of barley with two rows of kernels on each stem. They are larger in size and present a more uniform appearance compared to six-row barley.
Two-row malt is a light-colored, highly fermentable malt used in many different beer styles. It is often used to create light-colored ales, lagers, and some darker beers. They produce less protein content but higher flavor malt extract.
Six-Row
Compared to two-row, they're much thinner in size and present a less uniform appearance with a higher protein content and a slightly lower starch content. This grain is popular for many brewers due to its higher yield and extract potential.
Six-row barley malt is typically used in lagers and light-bodied ales. The higher protein content of six-row barley helps to create a fuller body, which is ideal for these beer styles. Six-row barley malt lowers starch content and also helps create a crisp and refreshing beer.
Winter Two-Row
Winter Two-Row barley is typically planted in the fall and allowed to grow over the winter months. The cold temperatures and shorter days cause the plant to enter a dormancy period, allowing it to survive the winter months. It is a two-row barley variety known for its high protein content, making it ideal for brewing beer.
Winter Six-Row
Winter six-row barley is a hardy variety that can survive cold winter temperatures and is well-suited for outdoor cultivation. Winter six-row barley is a popular choice among brewers because of its ability to produce a variety of beers. It can be used to make pale ales, stouts, and lagers. Because of its high protein content, it is also often used in the production of high-gravity beers.
Why Use Malt Barley When Brewing?
Brewing beer is an ancient art that has been around for centuries, and malted barley has been an essential ingredient in the process since the beginning. Without malted barley, beer wouldn't be the same. It is an essential part of the brewing process, and brewers should always use the highest quality malt for the best results.
Types Of Malts
Each type of malt has its own unique flavor and aroma and can be used to create different styles of beer. You can utilize the different malts listed here to guide your homebrewing process.
Base Malts
Base malts are the foundation of any beer recipe and provide the majority of fermentable sugars, body, and color to the finished product. They are made from grains that have been malted, meaning they have gone through a process of steeping, germinating, and kilning. Base malts are the most common type of malt and are used in almost every beer recipe.
The most common base malts are:
- Pale Ale Malt
- Munich Malt
- Pilsner Malt
Specialty Malts
Specialty malts are malts that are used to add flavor, color, and aroma to beer. These malts are made from grains that have been kilned for longer in the malting process to enhance their flavor and color. Specialty malts can be used in small amounts to add complexity to a beer, or in larger amounts to create a unique flavor profile.
The most common specialty malts are:
- Caramel Malt
- Crystal Malt
- Chocolate Malt
Kilned/Roasted Malts
Kilned/Roasted Malts are malts that are heated in a kiln to varying degrees. This process is used to produce a range of malt types, from light to dark. The degree to which the malt is kilned will determine the color, flavor, and aroma of the malt. The more intense the kilning process, the darker the malt and the more intense the flavor and aroma.
How Does Malt Affect Your Beer?
Malt affects the beer in several ways:
Sugar Content
The sugar content of malted barley is determined by the amount of starch that is converted to sugar during the malting process. Starch is the main component of malted barley and is converted to sugar by the enzyme amylase. This conversion process is known as saccharification.
Aroma and Flavor
Adding malted barley to your beer is a great way to add aroma and flavor to your brew. Malted barley is made by germinating grains, then drying them with hot air. This process creates a range of complex flavors, from sweet and nutty to bitter and roasted. Malted barley can also be kilned, which helps to develop more intense flavors.
Color
The color of the beer is determined by the type of malt used, the amount of malt used, and the amount of time the malt is roasted. The longer the malt is roasted, the darker the beer will be. The most common malts used to add color are pale, Munich, crystal, and chocolate.
