(Makes 5 Gallons) We recently had a simple, yet exciting idea: What if we brewed the same recipe, used the same yeast, but changed one thing - the flavor, aroma, and dry hop additions using one hop varietal. That way we could take two beers that are close to identical and pick out the differences in just the hop flavors and aromas! And thus, the Single Hop Experiment was born. This recipe is based off of a simple Pale Ale: Ultralight malt extract, Crystal 15L, Magnum bittering hops, and then a single other hop for the rest of the additions. The malt in this recipe is basic and fairly neutral, the bittering clean and consistent, but the flavor and aroma from the late hop additions will vary; sometimes dramatically! Ever wanted to know what your favorite hop really is? Brew a few of these different Single Hop Experiment recipes to find out! Centennial: The aroma/flavor is definitely American in nature with pungent aromas and pronounced flavor. Similar to, and blends well with Cascade, but without the grapefruit flavors of Cascade.
