Sierra Nevada Brewing has sidelined Anniversary Ale and instead will use the fall release slot for Tumbler Autumn Brown Ale later this year when the leaves are turning brown.
It appears to be part of the strategy that heralded Glissade in spring to bookend the tremendous 30th Anniversary brews. The second of which, the Imperial Helles, should be on finer beer store shelves now.
I am very excited to try this beer. Sierra Nevada is a super reliable brewer, their Glissade and Summerfest beers were very good, and their anniversary brews are typically great. On top of that, brown ales are among my favorite styles.
Going to get my hands on this when it comes out and will report back.
