The 2007 Anniversary Ale features prominent usage of Cascade hopsââ¬â the signature hop used in Sierra Nevada’s most popular product, Pale Ale. It is an American Style IPA with a big, fragrant pine and citrus hop aroma balanced by the sweetness of two-row pale and caramel malt. It finishes with an additional Cascade dry-hopping creating a big hop aroma Sierra Nevada fans will look forward to.
