Wheat In Beer: What's The Deal?

Beer is a popular alcoholic drink that has been enjoyed for thousands of years. It is traditionally brewed with four ingredients: water, malted barley, hops, and yeast. However, some beer recipes call for wheat to be added, which affects the flavour and body of the beer. Wheat beers, such as Belgian-style Witbier, tend to have a lighter, crispier character and a subtle wheat flavour. In this article, we will explore the role of wheat in beer and whether it is always present in this beloved beverage.

Wheat beers have higher gluten levels than other beers

The amount of gluten in beer can vary depending on the type of beer and the brewing process. Wheat beers, which tend to be pale and hazy, often contain more gluten than other beer styles. For example, the average gluten content of wheat beer is around 25,920 ppm, while beers made with barley contain approximately 19 to 45 ppm of gluten.

In most countries, food and beverages must contain fewer than 20 ppm of gluten to be considered gluten-free. This is because individuals with celiac disease or gluten sensitivity must completely exclude gluten from their diets. For these people, gluten can cause damage to the intestines, stomach pain, diarrhoea, unexplained weight loss, and poor absorption of nutrients.

Wheat beers are brewed with a large proportion of wheat relative to the amount of malted barley. The two main varieties are German Weizenbier and Belgian witbier, which is made with up to 50% raw wheat. Other types of wheat beer include Lambic (made with wild yeast), Berliner Weisse (a cloudy, sour beer), and Gose (a sour, salty beer).

While wheat beers have higher gluten levels than other beers, it's important to note that not all beers contain wheat. Beer is traditionally brewed with water, hops, yeast, and barley, and some beer recipes call for wheat to be added to build body and flavour. However, most beers do contain gluten, as barley, wheat, and rye are all grains that naturally contain gluten.

Wheat beers are hazy and pale

The two main varieties of wheat beer are German Weizenbier and Belgian Witbier. German Weizenbier, or Weißbier, is a light-coloured, top-fermenting beer that uses at least 52% wheat to barley malt. Belgian Witbier, on the other hand, uses flavourings such as coriander and orange peel, and is often made with raw unmalted wheat. Both varieties are termed "white beers" because "wheat" and "white" have the same etymological root in most West Germanic languages.

Other styles of wheat beer include Berliner Weisse, Gose, and Lambic, which are made with a significant proportion of wheat. Berliner Weisse is a cloudy, sour beer, while Gose is a sour and salty beer. Lambic is made with wild yeast and is another type of wheat beer with a cloudy appearance.

Wheat beers, such as Hefeweizen, are also known for their relatively high carbonation, which helps to balance the beer's malty sweetness. The haze in wheat beers can be accentuated by the addition of yeast, which is sometimes added to the beer or roused to create a cloudy look.

Wheat is added to beer to build body and flavour

Wheat is added to beer to enhance its body and flavour. Wheat beer is often light in colour and has a distinctive "white" appearance due to the suspended yeast and wheat proteins. The haze created by the wheat proteins contributes to a cloudy look. Wheat beers also tend to have a low hop bitterness and relatively high carbonation, resulting in a well-balanced beer. The wheat proteins provide a firm and long-lasting creamy head, adding to the overall sensory experience.

The type of wheat used in brewing can vary, with both raw and malted wheat being common choices. Raw wheat produces beers that are less sweet and full-bodied, while malted wheat adds a unique malty flavour. The use of wheat in beer also has an impact on the brewing process. Wheat absorbs water more quickly than barley, and the lack of husks can lead to clumping during the kilning process.

Wheat beers are known for their unique flavour profiles. The wheat malt contributes to the formation of esters, resulting in fruity notes such as banana, bubble gum, and vanilla. Additionally, the high protein content of wheat enhances foam stability, creating a better and longer-lasting head on the beer. Wheat beers also tend to have a lighter mouthfeel and a dash of crisp acidity, making them refreshing and easy to drink.

The addition of wheat to beer not only contributes to its flavour and body but also enhances its sensory attributes and overall drinking experience. Wheat beers have gained popularity worldwide, with many craft brewers offering their own unique takes on this traditional style.

Wheat beers have a distinct natural quality

Belgian Witbiers are made from raw materials, including unmalted wheat and pale barley malt, as well as characteristic flavour enhancers such as Curaçao bitter orange peel and coriander. They are light and cloudy with a pleasant aroma and a citrus flavour.

Bavarian Weizenbiers are traditionally brewed with a large proportion of wheat relative to the amount of malted barley. They are golden, fruity, and thirst-quenching. The Hefeweizen style is particularly noted for its low hop bitterness and relatively high carbonation.

American wheat beers are also available, with some brewers using wheat as a secret ingredient in their ales. Wheat beers are often the palest selection offered by craft brewers.

Wheat beers have a higher protein content than beers made from other grains, which contributes to foam stability and increases the beer's mouthfeel. Wheat beers also have high contents of compounds known for their bioactive and antioxidant effects, such as vitamins, minerals, amino acids, and polyphenols.

Wheat beers have a better, longer-lasting head

Additionally, the type of glassware used can also impact the head retention of wheat beers. Wheat beers are often served in tall, narrow glasses, which minimize exposure to ambient air and reduce the ability for carbon dioxide (CO2) to escape. By trapping the CO2, the narrow glasses help to maintain the head and prevent it from dissipating too quickly.

The brewing techniques and ingredients used in wheat beers also play a role in head retention. For example, the use of higher mash temperatures can result in longer dextrin chains and lower attenuation during fermentation, enhancing the head retention. Furthermore, the specialized strains of yeast used in wheat beers, such as Weizenbier, can produce fermentation by-products that contribute to a more stable head.

Overall, the combination of a high wheat content, appropriate glassware, and specific brewing techniques contributes to the longer-lasting head typically associated with wheat beers. These factors work together to create a stable and durable foam that enhances the drinking experience and is characteristic of wheat beers.
