Like pinwheel caps and Cosby sweaters, hops—the bitter flowers used to flavor some of your favorite beers—are forever going in and out of fashion. For a while, brewers couldn’t get enough of super-citrusy Centennial (found in beers like Stone Ruination and Bell’s Two-Hearted Ale), before being smitten by piney Simcoe. Then along came the white wine–like Nelson Sauvin and tropical Citra, which stole the hearts of brewers and beer lovers alike.
