Wheat To Beer: Brewing Process Explained

Wheat beer is a versatile beverage with a long history. Wheat beers are brewed with a blend of wheat and barley, with wheat constituting 30-70% of the total. Wheat beers have a soft, crisp flavour that complements the addition of berries and other fruits. Wheat beers are often hazy with proteins and offer a distinct contrast to the brightly filtered industrial brews. Wheat beers are also known for their foam stability and mouthfeel. The most popular styles of wheat beer include German Hefeweizen, Belgian Witbier, and American Wheat beer.

Wheat and barley are blended, with wheat making up 30-70% of the total

Wheat beers are typically made with a blend of wheat and barley, with wheat making up 30% to 70% of the total blend. Wheat extract malts are usually made up of 40% wheat and 60% barley. Wheat has a higher protein content than barley, which contributes to a longer-lasting head on the beer and a fuller sensation in the drinker's mouth. However, the higher protein content can also create problems in the brewhouse and make the beer hazy.

Wheat is also lighter in colour and has a softer, crisper flavour than barley, which lends itself well to summer beers and provides a good base for the addition of berries and other fruits. Wheat beers are often hazy and provide a distinct contrast to the brightly filtered "industrial" brews.

Wheat is also subject to a variety of terms, such as "hard" or "soft", which refers to the kernel's texture. Hard wheat kernels have a coarser particle size and are used for bread, while soft wheat kernels are used for cakes and cookies. Wheat can also be defined as "red" or "white", referring to the colour of the seed coat. In the US, red wheat is usually hard red wheat and is grown throughout the Great Plains states. In the UK, only red wheat is cultivated due to its damp climate.

The varying protein levels between wheat and barley present some challenges in the brewing process. Wheat lacks barley's husk, which means it absorbs water more quickly and has shorter steeping times. Wheat also reaches modification more quickly than barley, but it is relatively less modified. Kilning for wheat is done at lower temperatures than barley, but the higher protein content results in a slightly darker colour.

Wheat has more proteins than barley, which creates a long-lasting head

Wheat beers are typically brewed with a blend of wheat and barley, with the wheat portion ranging from 30% to 70% of the total. Wheat has more proteins than barley, and these proteins contribute to a long-lasting head on the beer.

Wheat is higher in protein and starch than barley. The varying protein level is the most significant difference between the two grains. Wheat offers higher yields, with typical pale malt extracts ranging from 80% to 83%, while wheat malt extracts range from 84% to 88%.

The higher protein levels in wheat enhance foam stability, resulting in a better and longer-lasting head on the beer. Additionally, the high-molecular-weight proteins in wheat allow a dense head to form. However, the downside of higher protein levels is that they can create haziness in the beer and cause problems during the brewing process.

Wheat beers are often hazy with proteins, offering a distinct contrast to the brightly filtered "industrial" brews. Wheat beers are popular summer refreshers due to their soft, crisp flavour and natural quality.

Wheat and barley are both grains that have been cultivated and consumed by humans for thousands of years. They are similar in taste and appearance but have some key differences in terms of processing, usage, nutrition, and health effects. Wheat, for example, needs to be milled and processed into flour before use, whereas barley can be cooked and consumed as a whole grain, similar to rice.

Wheat beers are hazy, with a distinct flavour profile

Wheat beers are unique in their hazy appearance and distinct flavour profile. The haze is a result of the wheat content, which typically ranges from 30% to 70% of the total blend, with wheat extract malts usually consisting of 40% wheat and 60% barley. Wheat contains more proteins than barley, contributing to a longer-lasting head and a hazier appearance.

The flavour profile of wheat beers is often light to medium-bodied, with minimal hoppy bitterness and fruit flavours. Instead, they accentuate the malt profile, resulting in a smooth and refreshing taste. The specific flavours can vary, but wheat beers are known for their unique taste, often incorporating exotic spices and fruits. Common flavour notes include clove, orange peel, banana, and coriander, derived from the yeast strains used.

German Hefeweizens, for example, are known for their unfiltered, hazy appearance and distinct banana and clove flavours. Belgian Witbiers, on the other hand, incorporate coriander and orange peel, resulting in a crisp and slightly tart flavour profile. American wheat beers tend to have a neutral yeast character, lacking the banana and clove flavours of German varieties, and instead offering delicate citrus notes.

The versatility of wheat beers allows for various flavour combinations and styles, making them a popular choice for craft beer enthusiasts and those looking for a refreshing summer beverage.

German Hefeweizens are brewed with special yeasts that produce clove and banana flavours

Wheat beers are brewed with a blend of wheat and barley, with the wheat portion ranging from 30% to 70% of the total. Wheat has more proteins than barley, which contributes to a long-lasting head, and its lighter colour makes it a great base for a summer brew.

The fermentation temperature is crucial to the flavour profile of the beer. Fermenting at a temperature of 62 °F (17 °C) will produce the best results. However, it is important to note that increasing the ratio of glucose to maltose in the wort will also increase the production of isoamyl acetate, resulting in a more pronounced banana flavour.

To enhance the banana flavour in a Hefeweizen, brewers can also adjust the pitching rate or other factors that affect growth. Additionally, fermentation temperatures above 72 °F (22 °C) will enhance banana flavours, while temperatures below this will enhance clove flavours.

Belgian Witbiers use coriander and orange peel, and a special yeast that ferments crisp

Wheat beers are typically brewed with a blend of wheat and barley, with the wheat portion ranging from 30% to 70% of the total. Wheat beers are often hazy with proteins and offer a distinct contrast to the brightly filtered "industrial" brews. Belgian Witbiers (white beers) are a style of wheat beer that originated in Belgium and are known for their unique white, cloudy appearance.

Belgian Witbiers use a special type of yeast that ferments crisp with a slight tartness. The yeast strains recommended for this style include Wyeast 3942 (Belgian Wheat), Wyeast 3944 (Belgian Witbier), and White Labs WLP400 (Belgian Wit). In addition to the yeast, coriander and orange peel are added during the last 5-15 minutes of the boil to enhance the flavour and aroma of the beer. Coriander contributes a pleasant citrus character when crushed seeds are added to the boiling wort, while orange peel adds a citrusy fruitiness. The spices should be used sparingly, as too much can overpower the other flavours in the beer.

The grain bill for a Belgian Witbier typically includes unmalted wheat, continental Pilsner malt, and oats. The unmalted wheat and oats contribute to the cloudy white colour and persistent head of the beer. It is recommended to use light-coloured malts to maintain the white appearance of the beer. The fermentation temperature for Belgian Witbiers should be controlled, starting around 62-65°F (16.7-18.3°C) and gradually increasing to 70-75°F (21.1-23.9°C) by the end of fermentation.
