Yesterday, Hill Farmstead Brewery released Twilight of the Idols and Birth of Tragedy in 500ml bottles, two beers named after works by Friedrich Nietzsche.

Twilight of the Idols is the Greensboro Bend, Vt.-based brewery’s winter porter with locally roasted coffee and cinnamon and then they age it on vanilla beans. “Originally conceived with a friend in 2009 while brewing in Denmark, the name of this annual release is inspired by the title of one of the last texts written by one of our philosophical idols, Friedrich Nietzsche,” reads a description on the brewery’s website.

It’s $8 per bottle with a 12-bottle limit. Twilight Of The Idols was first released in 2010 and measure 7.5 percent ABV.

Birth of Tragedy is the imperial and bourbon barrel-aged version of Twilight of the Idols. Originally released in 2011, Birth of Tragedy uses bourbon barrels from their favorite distilleries.

It’s $20 per bottle and has a four bottle limit. Birth of Tragedy clocks in at a slightly higher 9 percent ABV.
