Today’s an exciting day if you’re a fan of some big, black beers.  Starting today you should be able to find both the Goose Island Night Stalker Imperial Stout and the Sierra 30 – Fritz And Ken’s Ale, a 30th Anniversary collaboration stout from Sierra Nevada and Anchor Brewing.

Here’s some of the information I could dig up about each beer:

Night Stalker:

A heavily-hopped imperial stout, Night Stalker is a heavyweight of a beer. It delivers a formidable punch of hops and rich roasted malt notes to the nose in a silky body that’s as dark as night.

Sierra 30 – Fritz And Ken’s Ale
Notes:
Fritz Maytag, owner of San Francisco’s Anchor Brewing Company, is regarded as the godfather of the craft brewing movement. Fritz agreed to guest brew this very special ale with us in honor of our 30th anniversary. As a nod to the robust black ales that seduced both Fritz and Ken in the early years, we bring you this Pioneers Stout, a rich and roasted ale, perfect for aging, and worth of your finest snifter. Enjoy!

Charity:
Fritz Maytag has always had a passion for knowledge. As a child in Iowa, he learned early about the wealth of information available to him at his local library. Maytag chose to donate to the Butte County Library system, which is library district local to Chico, California-home to Sierra Nevada Brewing.
