WhistlePig 15 Year Straight Rye Whiskey is hand bottled at 92 proof on the WhistlePig Farm with their calling-card, Canadian mash bill of 100% rye. 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. One experiences a complex mingling of flavors when tasting WhistlePig 15 Year. The butterscotch appearance is reflected in the creamy sweetness that hits the front of the tongue. Then the peppery spice comes along and forcefully hits mid-palate with a pleasant heat. An oaky earthiness lingers in the long, deep finish that is not at all dry. There is nothing subtle about this whiskey as it delivers bold flavor without the burn.
