Yeast is the ingredient most beer drinkers learn last, partly because it is hard to see. Malt sits in bags. Hops smell loud before they ever reach the kettle. Water is obvious because beer is mostly water. Yeast arrives as a small pitch of cells and then disappears into the fermenter, where it quietly changes sweet wort into beer. That hidden work makes it easy to treat yeast as a switch that turns sugar into alcohol, but that is only the beginning. Yeast decides whether a beer feels crisp or round, clean or fruity, spicy or neutral, dry or sweet, settled or hazy.
