WhistlePig 15 year old Straight Rye Whiskey is hand bottled at 92-proof on the WhistlePig Farm Estate using their flagship Canadian mash bill of 100% rye. Sourced from an unnamed Canadian distiller after aging for 10 years in refill ex-bourbon barrels, this exceptionally crafted rye whiskey is finished for another 5 years in the WhistlePig's very own distinct, home-grown oak barrels. To the eye, this 15 year old whiskey has the rich golden brown color of butterscotch candy. It is mellow to the nose, with an initial burnt fruity citrus wafting out followed by the distinct spiciness of rye.
