Bourbon Enthusiast WhistlePig Estate Oak Rye 15 Year 750 mlOne of WhistlePigs oldest whiskeys, Estate Oak Rye is for the true connoisseur of Rye. It takes its name from our Vermont Estate Oak, where it finishes its long, 15 year life. Sustainably harvested right off our 500 acre farm, the wood has more rings than the standard American oak used in whiskey barrels, imparting more flavor during maturation. Custom toast and char profiles takes the flavor even further, just like a perfectly toasted marshmallow.
