Hill Farmstead Brewery is releasing an “experimental” that was brewed eight mouths ago.

The beer is Madness & Solitude, a 10.5 percent ABV imperial IPA brewed with pale malt and dextrose along with centennial, chinook, Columbus, Simcoe and Warrior hops before being aged in both second- and third-use bourbon barrels. Madness & Solitude, which was brewed in March, uses the Greensboro, Vt.-based brewery’s Ephraim IPA (9.6 percent ABV) as its base.

According to a post on Hill Farmstead’s website, Madness & Solitude is a draft-only release that will only be available in 750ml growlers ($15) with a limit of two per person when it goes on sale at the brewery on Nov. 18.
