What is Brewer’s sugar?

Answered by Daniel Conrad

Brewer's sugar, also known as glucose or corn sugar, is a type of sugar that is commonly used in to improve fermentation and reduce the “tang” in homemade , , , and . It is a versatile ingredient that is preferred over regular household sugar (sucrose) in brewing due to its specific characteristics and benefits.

One of the main reasons brewer's sugar is used is because it is easily fermentable by . When yeast is added to a fermentation vessel, it starts to break down the sugars present in the liquid to produce and carbon dioxide. Regular household sugar, sucrose, needs to be first broken down by the yeast into glucose and fructose before fermentation can occur. Brewer's sugar, on the other hand, is already in the form of glucose, which makes it readily available for yeast to consume and convert into alcohol.

By using brewer's sugar instead of sucrose, brewers can achieve a more efficient fermentation process. The glucose in brewer's sugar is quickly consumed by the yeast, resulting in a faster and more complete fermentation. This can lead to a higher alcohol content in the final product and a cleaner taste. The use of brewer's sugar also helps to avoid any residual sweetness that may be left behind when using sucrose.

Furthermore, brewer's sugar is known for producing a more neutral flavor profile compared to sucrose. Sucrose can sometimes contribute a slight “tang” or “cider-like” taste to the finished product, especially in wines and ciders. Brewer's sugar, being primarily glucose, does not have the same effect and allows the other flavors in the to shine through.

In my personal experience as a brewer, I have found that using brewer's sugar can make a noticeable difference in the quality of the final product. The fermentation process is more vigorous and the resulting beer or cider has a cleaner and more balanced flavor. I have also found that brewer's sugar dissolves more easily in liquid compared to regular household sugar, making it easier to mix into the brewing process.

To summarize, brewer's sugar is a type of sugar, specifically glucose, that is used in brewing to enhance fermentation and improve the flavor of homemade beverages. It is preferred over regular household sugar due to its ease of fermentation, neutral flavor profile, and ability to dissolve easily. By using brewer's sugar, brewers can achieve a more efficient and enjoyable brewing experience.
