Festbier flavor differences are attributable to which factors?

• A. Hops and water chemistry
• B. Maltsters and yeast
• C. Fermentation temperature only
• D. Age of malt

Answer: (B)

Flavor differences among Festbiers come primarily from the malt character provided by different maltsters and from the yeast used. The maltsters’ malts shape the beer’s sweetness, body, and toastiness—Pilsner, Munich, Vienna, and specialty malts each contribute distinct flavors that define a Festbier’s malt-forward profile. The yeast, a lager strain, ferments cleanly at cool temperatures and can add subtle distinctions in finish and mouthfeel, with slight variations in attenuation and any remnants of ester or diacetyl handling. While hops and water chemistry affect bitterness, aroma, and mouthfeel, they don’t account for the broad, brand-to-brand flavor differences as much as the chosen malt bill and yeast. Fermentation temperature plays a role, but it isn’t the sole driver, and aging malt isn’t the main factor in shaping Festbier’s characteristic flavors.
