Some of the best rye whiskey around comes from the folks at WhistlePig in Vermont. And their latest release, which is also their oldest to date, is another step forward for the brand. WhistlePig 15 Year Rye Whiskey is sourced from Canada, and then finished in custom charred barrels made from Vermont White Oaks trees found on the WhistlePig Farm. The trees have a denser wood grain than the wood from most barrels, which imparts a distinct flavor into every bottle of whiskey. It clocks in at 92 proof and is made using a 100% rye mash bill.
