This week, Hill Farmstead Brewery is rereleasing its first collaborative saison.

Phenomenology of Spirit 2018 is a blend of “dark Farmstead® ale” that has been aged for more than eight months in both red wine barrels and bourbon barrels that had formerly been used to age the brewery’s maple imperial stout. The first incarnation of the ale was brewed in collaboration with Tired Hands Brewing Co. and McKenzie Brew House in 2010.

The beer gets its name from German philosopher Georg Wilhelm Friedrich Hegel’s most famous philosophical work titled Phänomenologie des Geistes that was published in 1807.

According to Hill Farmstead, Phenomenology of Spirit 2018 will be packaged in 750ml bottles ($30) and will have a two bottle per person purchase limit when it goes on sale at the brewery on Oct. 10.
