Fegley's Brew Works Insidious - Barrel Aged

Also known as Fegley's Brew Works Insidious - Bourbon Barrel
Commercial description
Brewed by Allentown Brew Works, Allentown, PA. To cast the spell we squeeze the life from malts and roasted barley, boil their spirits with East Kent Golding hops, unleash an English ale yeast to feast upon it, and finally lock their remains in charred bourbon barrels....What emerges is a black deity-sized libation that will be your portal to the dark side.
