Springbank K&L Exclusive 13 Year Single Bourbon Barrel Cask Strength Single Malt. Really reminds me of the legendary Bourbon Wood. K&L say they wanted "something that exemplified the true character of Springbank - that unmistakable dense mouthfeel, brimming with chewy, gum-smacking texture and viscosity. Springbank whisky from a straight bourbon cask is one of the true pleasures in life. While the heavily sherried versions of the malt are wonderful in their own way, the sweetness from the sherry tends to mask some of qualities we love so much. We tasted this 13 year straight out of the barrel and loved the rich tannins provided from the wood, the intense vanilla aromas, and the nutty flavors that intermingled with salty accents.
