After almost two years of aging, Hill Farmstead Brewery is releasing the latest version of its barrel-aged stout named after a book published by the German philosopher Fredrick Nietzsche in 1887.

Genealogy of Morals 2018 is an imperial wheat stout brewed with coffee sourced from Central America and aged “in a selection of bourbon barrels from our favorite distillers” for more than 20 months. The base beer is the Greensboro, Vt.-based brewery’s Genealogy, an imperial stout brewed with coffee that is conditioned in stainless steel.

According to a post on Hill Farmstead’s website, Genealogy of Morals 2018 will be available in 500ml bottles ($22) with a three bottle per person purchase limit when it is released exclusively at the brewery on June 6.
