Recently I discovered a little piece of the whiskey industry and decided to explore it a little bit: wine barrel finished whiskies. The two whiskies I tasted are distilled and aged as whiskey, then re-barreled by Napa Valley wineries in their used wine barrels and aged for a period of time in Napa.

Slaughter House is a product of Splinter Group in Napa, home of the Orin Swift family of wines. For Slaughter House, they barrel a 9-year-old Tennessee whiskey (distilled from 95% corn and 5% wheat) in their Papillon barrels (a red wine blend).

Slaughter House is bold and spicy , with a nose of apricot, berries and caramel followed by a flavor of cinnamon-and-sugar and marzipan. From the flavor of the whiskey, I have trouble detecting the wine’s contribution, though Slaughter House is certainly a solid whiskey when stood alone. With a price in the mid-$30 range, it’s a good buy for a solid spice-heavy 9-year-old whiskey.

Amador Whiskey Co’s Double Barrel Bourbon is a blend of 3-10 year old Kentucky bourbons, then is re-barreled in Napa for 6 months.

Also a mid-$30-priced whiskey, Amador Double Barrel is barreled by the spirits division of Trinchero Family Estates. Chardonnay barrels were used for aging and the wine barrel contribution is much more obvious. It’s nose is floral and sweet corn, with a finish that is crisp and clean, clearly echoing the Chardonnay. Amador has almost no traces of spiciness, and is much milder start-to-finish than Slaughter House. I suspect that this flavor profile could translate to a broader appeal to more drinkers, too (ladies, I’m looking at you).

Whiskey is no stranger to barrel polygamy. Whether it’s something like these wine-barrel finishes, or larger brands like Angel’s Envy (finished in Port barrels) or Balvenie Double Wood, the depth of flavor that gets added through barrel exploration like this makes for some very delicious drinking.
