Sorry - just now saw your question. These are 2 liter barrels, made of new white oak and properly charred. One of the barrels will run you $45 dollars. You can also buy an 18.5 liter barrel, or a 194 liter barrel! The 194 liter job comes filled and delivered to your door!

I toured the Copper Fox Distillery back in May when my wife and I were vacationing at Shenandoah National Park - that’s when I bought my barrel. The guys who run the place (it’s VERY small) are terrific!.
