Wheat Grain In Beer: What's The Deal?

Wheat is a common ingredient in beer, and its use in brewing dates back centuries. Wheat is packed with proteins, which help create a fuller body, a soft, crisp flavour, and a foamy head. Wheat beers are typically light in colour, low to medium in alcohol content, and can be cloudy or clear in appearance. They are often brewed with other grains such as barley, and the most widely known wheat beer is hefeweizen, a refreshing style from Germany that has become popular around the world.

Wheat beer is a category of beer that originated in Bavaria

Weissbier, or weizenbier, is the German term for "white beer", referring to the pale air-dried malt, as opposed to "brown beer" made from dark malt dried over a hot kiln. The term "weissbier" is used almost exclusively in the southern German state of Bavaria and in Austria. Weizenbier, or simply "weizen", is used in the western and northern German regions, as well as in Switzerland.

Wheat beer was introduced to Bavaria in the 15th century from neighbouring Bohemia. However, due to the Bavarian Purity Law of 1516, which only allowed beer made from barley to be brewed, wheat beer production was halted. In 1548, William IV, Duke of Bavaria, gave Baron Hans VI von Degenberg a special privilege to brew and sell wheat beer. After the last of the Degenbergers died without an heir, Duke Maximillion I of the House of Wittlesbach became entitled to Degenberg's estate, including the brewing privilege for Weissbier. He monopolised the market and set up breweries all over Bavaria, making wheat beer very popular.

Wheat beer fell out of favour in the early 18th century and in 1872, King Ludwig II sold the brewing rights to George Schneider I, a brewer in Bavaria, ending the wheat beer monopoly. Wheat beers then made up a small fraction of all beer sold in Germany until after World War II, when they were rediscovered and sales were rejuvenated. Today, wheat beers make up almost a quarter of all beer sold in Germany.

Wheat beers are typically light in colour, low to medium in alcohol content, and can be cloudy or clear

Wheat beers are often light in colour, with the German Weißbier and Belgian Witbier (both meaning "white beer") being notable examples. Weißbiers are light in colour because they are made with a large proportion of wheat malt, which is air-dried and pale. Witbiers, meanwhile, are often made with raw unmalted wheat and are hazy or cloudy due to the presence of suspended yeast and wheat proteins.

Other wheat beers, such as Berliner Weisse, Gose, and Lambic, are also made with a significant proportion of wheat and tend to be cloudy or sour.

The alcohol content of wheat beers can vary depending on the brewery and type, but they typically have a low to medium alcohol content, ranging from 2.5% to 5% ABV. Some wheat beers, like Weizenbock, have a much higher alcohol content than their lighter cousins.

Wheat is used in brewing because it is full of protein, which creates a fuller body, a smooth and foamy head, and a hazy appearance. The higher protein levels in wheat also contribute to better foam stability and increase the beer's mouthfeel.

Wheat is full of protein, which creates a fuller body and mouthfeel, and a foamy head

Wheat is a common ingredient in beer, often used in conjunction with barley. Wheat is full of protein, which has several benefits for the resulting beer.

One of the key advantages of using wheat in brewing is that it creates a fuller body and mouthfeel. The high protein content in wheat contributes to a sensation of palate fullness and viscosity, making the beer feel thicker and smoother in the mouth. This is an important characteristic that distinguishes different styles of beer, with American lagers classified as light-bodied and bock beers and imperial stouts as full-bodied.

Wheat also enhances the foamy head of the beer. The proteins in wheat act as a structural component in the foam, improving head retention. This means that wheat beers often have a better, longer-lasting head. The higher protein content in wheat increases foam stability, resulting in a more stable and durable head on the beer.

In addition to its impact on body and head retention, wheat also affects the appearance and flavour of beer. Wheat beers are often hazy or cloudy due to the presence of proteins. This natural quality is appreciated by beer drinkers, who enjoy the contrast it offers to brightly filtered industrial brews. Wheat also has a soft, crisp flavour that provides a good background for additions of berries and other fruits.

When used in brewing, wheat typically constitutes a large proportion of the grain bill, ranging from 5% to 10% or even up to 40% to 60% in some wheat beers. It is worth noting that while wheat improves head retention, excessive amounts can lead to problems in the brewhouse and haze in the final product. Finding the right balance is crucial to achieving the desired characteristics in the beer.

Wheat beers are usually top-fermented ales, and must contain a high percentage of malted or unmalted wheat

Wheat beers are usually top-fermented ales, and they must contain a large proportion of wheat relative to the amount of malted barley. Wheat is used to create a fuller body, mouthfeel, and a foamy head. The two main varieties are German Weizenbier and Belgian Witbier, but wheat beers can come in many shapes and sizes.

German Weizenbier, or Weißbier, is a top-fermenting beer that uses at least 52% wheat to barley malt. It is a light-coloured beer that is well known throughout Germany, though it is better known as Weizen ("Wheat") outside of Bavaria. The terms Hefeweizen ("Yeast Wheat") or Hefeweissbier refer to wheat beer in its traditional, unfiltered form. The term Kristallweizen (crystal wheat) refers to a wheat beer that has been filtered to remove the yeast and wheat proteins that contribute to its cloudy appearance.

Belgian Witbier, or Witbier, is a barley/wheat, top-fermented beer brewed mainly in Belgium and the Netherlands. It gets its name from the suspended yeast and wheat proteins that cause the beer to look hazy or white when cold. Witbiers can be brewed from step infusion or decoction mashes, but long protein rests are necessary to allow any lautering at all. Care is taken so that some proteins remain to provide the defining golden haze.

Wheat beers can also be categorised as Weizenbock and Dunkelweizen. Weizenbock is a stronger version of Hefeweizen that is also brewed with darker Munich malts. Dunkelweizen is a dark Hefeweizen that falls within the same ABV range as its lighter cousin.

Wheat beers are usually designed to be rich in body but easy to drink. Wheat is a high-protein grain, and when used in the mash, these proteins carry over to the final beer to boost mouthfeel and provide a perception of richness. A good wheat beer will have a distinctive fresh bread character, soft mouthfeel, and a long-lasting, tight foam.

German wheat beers tend to use about 50% malted wheat and 50% malted barley

Wheat beers are top-fermented beers that 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. Wheat beers originated in Continental Europe, with the first true wheat beer brewery built in the Bavarian region of Germany in the 15th century.

German wheat beers, or Weizenbier, tend to use about 50% malted wheat and 50% malted barley. In fact, German wheat beers require a minimum of 50% wheat malt in the mash, and rarely contain more than 70% due to the risk of brewhouse problems. In comparison, traditional Bavarian weissbiers were brewed with up to 60-70% wheat malt, combined with 30-40% barley malt.

Wheat is used in brewing because of its high protein content, which enhances foam stability and increases the beer's mouthfeel. Wheat also lends a soft, crisp flavour to the beer, creating a natural quality that works well as a background for additions of berries and other fruits. Wheat beers are often hazy with proteins, offering a distinct contrast to the brightly filtered industrial brews.

The varying protein levels between barley and wheat create the most significant difference in brewing. Wheat offers higher yields, with typical malt extracts running from 84-88%, compared to 80-83% for barley. The higher protein levels in wheat can, however, create problems in the brewhouse and make the beer hazy.
