THE INGREDIENTS
Four ways in.
Treat these as clues, not rules. The same ingredient can contribute differently depending on the recipe and process.
Water
Minerals in the brewing water can affect mash chemistry and how bitterness, dryness, or roundness is perceived. Brewers may adjust the water to suit a recipe.
Malted grain
Malt provides sugars for fermentation and helps shape color, body, and flavor. Depending on how it is prepared, notes may suggest cereal, bread, caramel, toast, cocoa, or roast.
Hops
These flowers can contribute bitterness and aroma. Variety and timing matter: common descriptors include citrus, floral, herbal, piney, and resinous.
Yeast
Yeast turns fermentable sugars into alcohol and carbon dioxide, while also creating aromatic compounds. Strain and fermentation conditions influence the result.
