Which of the following constitutes the majority of beer by weight?

Water constitutes the majority of beer by weight, typically making up about 90-95% of the total composition. This high percentage is essential because water is not only the primary solvent for the other ingredients but also plays a crucial role in the brewing process itself. It contributes to the extraction of flavors from the malt and aids in fermentation.

While malt, hops, and yeast are critical components in the brewing process, they represent a much smaller proportion of the overall weight of the finished beer. Malt is the source of fermentable sugars and contributes flavors and colors, but it is not present in amounts that compare to water. Hops add bitterness, aroma, and flavor, yet they are used in relatively small quantities. Yeast, while vital for fermentation, also makes up only a minor fraction of the beer’s weight.

Understanding the predominant role of water in beer helps to highlight its importance not just in terms of quantity but also in terms of the quality and characteristics of the final product.
