The fourth edition of Limestone Branch’s (aka Luxco, aka Lux Row) Yellowstone Limited Edition Kentucky Straight Bourbon has arrived. For 2019, the brand continues its trend of blending younger and older stock to create a complex finished product. Per the company, “This year’s edition includes a hand-picked selection of the most unique barrels – those hidden gems in the rick house – including barrels of extra-aged nine-year and 12-year Kentucky Straight Bourbon Whiskey.The nose is immediately buttery and rich, sweet with notes of vanilla, caramel, and butterscotch. Peanut butter and chocolate candy notes continue the theme. The palate is chewy and, as expected, quite sweet, with more vanilla and caramel notes dominating. These give way to some spice — cloves and allspice — before moving into a finish that develops a surprising fruit character, pineapple in particular. The butter notes — more brown butter here — continue to make their presence known, along with a tenacious spice character. Effusive from start to finish, this is dessert in a glass, a whiskey tailor made for the sweet tooth (rather than the bourbon purist).
