Today, let’s dive into the intriguing world of adjuncts in brewing, a territory that goes beyond the customary quartet of water, malt, hops, and yeast. From offering subtle flavour twists to cost-cutting measures, adjuncts play a myriad of roles in the brewing process. Let’s explore these behind-the-scenes beer heroes.

Adjuncts: What Are They?

In the brewing universe, ‘adjuncts’ refers to the ingredients that supplement or replace a portion of the traditional malted grains (mostly barley) in beer production. While they have often been used to reduce costs, craft brewers frequently turn to adjuncts to introduce unique flavour profiles and textures, making our pints even more exciting.

The Most Common Adjuncts

Here are some common adjuncts that brewers incorporate into their brews:

1. Corn and Rice: Used extensively in American light lagers, corn and rice are often employed as cost-cutting ingredients. They also lighten the flavour and body of the beer, making it more palatable for those who prefer a less ‘malty’ drink.
2. Oats: Loved by stout brewers, oats contribute to a silky mouthfeel and a creamy, robust head, making your pint of stout even more luxurious.
3. Wheat: Wheat is not just for wheat beers! It is used to increase the body and head retention in a variety of beer styles and can contribute to a hazy appearance.
4. Rye: Rye is the perfect adjunct for brewers seeking to introduce a unique, spicy character to their beers. It also adds a rich, reddish hue to the brew.
5. Sugars: Brewers often add sugars (like cane sugar, brown sugar, or beet sugar) to increase the alcohol content without adding extra body to the beer. Sugars also encourage yeast activity and can contribute to different flavours and aromas depending on the type used.
6. Fruits and Spices: From orange peels to coriander seeds, fruit and spice adjuncts are favourite tools of craft brewers to create a wide array of flavourful and aromatic brews.

Trends and the Future of Adjuncts

With craft beer’s surge in popularity, the use of adjuncts has shifted from being primarily cost-driven to an art form. Today’s innovative brewers are using everything from coffee, chocolate, and vanilla to more adventurous additions like chillies, seaweed, or even doughnuts to push the boundaries of beer flavours.

One emerging trend is the use of locally sourced ingredients as adjuncts, like Honey. Brewers are focusing on sustainability and terroir, using locally sourced fruits, herbs, and spices to both reduce their environmental impact and to create beers with a unique local character.

Ultimately, adjuncts play a vital role in brewing, adding dimensions to the brew and driving innovation in an age-old tradition. So next time you raise your glass, why not take a moment to appreciate the role of these unsung heroes in your perfect pint? Sláinte!
