"Their head distiller, Sienna Jevremov, explains that different whiskey styles are defined by production choices — including country or state of origin, mash bill, mashing and distilling methods, maturation vessel and duration, and blending — and she outlines legal bourbon requirements such as distillation below 80% ABV, barrel entry at no more than 60% ABV, and bottling at a minimum of 40% ABV, noting that proofing with water can occur after distillation." - Dylan Ettinger
