Greener Futures #37, dubbed "Castorgeist," is a terrifyingly tasty blend of screams, the unspeakable, and one of the longest-aged beers in our cellar. It is comprised of 2015's Screamin' Beaver Oak-Aged Double IPA, Pinot-Grigio-barrel-aged The Beer That Shall Not be Named (a Belgian-style amber), and Festivale altbier that aged for 43 months in white wine barrels.
Castorgeist pours hazy copper with an off-white head. Aromas of sour cherry, vanilla, butter and red wine are evident. Tart cherry flavour plays along with almond and sherry notes. The finish offers lingering tartness coupled with dry tannins.
