Which statement best describes the hops, yeast, and mash characteristics commonly associated with American IPA?

• A. Pale or 2-row base with toasted and caramel malts; British hops; Lager yeast.
• B. Pure pale malt with no caramel; New World hops; Clean ale yeast.
• C. Very high adjuncts with heavy caramel; English hops; yeast with fruity esters.
• D. American or New World hops; American or English ale yeast that's clean or with slightly fruity esters; mashed at lower temp for higher attenuation.

Answer: (D)

Hops, yeast, and mash approach define American IPA by a hop-forward profile that's balanced with a clean, often dry finish. The hop choice emphasizes American or New World varieties, which bring citrus, pine, and resin character that set this style apart from using traditional British hops. The yeast is typically an ale yeast that behaves cleanly or with only light fruity esters, so it doesn’t mask the hop aroma and bitterness. The mash temperature is set lower to produce a more fermentable wort, which leads to higher attenuation during fermentation and a drier finish that helps carry the hop bitterness and aroma without heaviness. This combination—American or New World hops, a clean or lightly fruity ale yeast, and a mash aimed at higher attenuation—best aligns with the standard American IPA profile.
