The 2 liter oak barrel is approximately 7″ from end to end and about 6″ in diameter. All barrels have a light finish on them to keep them looking great on your bar. A 2 liter barrel will hold about a half gallon. The two liter barrel will age your drink 20-25 times faster than the full size oak barrels used in distilleries. The 2 liter oak barrels is probably our most popular for gift giving since it is large enough to use with a handle of liquor (1.75L) and it is nice size to display on your bar since the barrel head engraving will be a bit larger than the 1 liter barrel. It’s the perfect gift size but if you are looking to really impress your gift recipient then we would suggest our 3 liter oak barrel.
