Yellowstone used to be one of the most popular bourbon brands in Kentucky in the 1960's. It is still produced today by NDP Luxco as a bottom shelf whiskey. The whiskey in this miniature was distilled for the Italian market at now closed Glenmore Distillery in Owensboro, KY (DSP-24-KY). Probably somewhere in the 1960 of 1970's. The magnificent Chuck Cowdery wrote a history of Yellowstone: http://chuckcowdery.blogspot.nl/2009/12/history-of-yellowstone-part-one-of-two.html and http://chuckcowdery.blogspot.nl/2009/12/history-of-yellowstone-part-two-of-two.html
Sweet vanilla intermingled with notes of pine and mint. Wood varnish. Grassiness and herbs of carraway and cummin. Becomes a little soapy later on.
Round and rich with rye spices and caramel. Hints of dried figs and dates. Oak dust. Beeswax. Some toasted almonds. Bitter chocolate at the end.
Medium long. Molasses. Ginger. Menthol. A decent and quite complex whiskey from the heydays of bourbon.
