The O.F.C. line of bourbons, as we’ve touched upon in the past, is a classy and pricey way for Kentucky’s Buffalo Trace distillery to showcase some of its older American whiskeys. The distillery released earlier this year, for example, three vintage bottlings, the oldest of which was from 1985. Now the ongoing series is back for a 2018 holiday release in the form of a bourbon from 1993.
