The start of Celebration season is a festive event. As soon as the first fresh hops arrive at Sierra Nevada, brewing begins. First brewed in 1981, Sierra Celebration Ale is one of the earliest examples of an American-style IPA and one of the few hop-forward holiday beers. Famous for its intense citrus and pine aromas, Celebration is bold and intense- featuring Cascade, Centennial and Chinook hops- honoring everything they have at Sierra Nevada.
