I've never actually tried Buchanan's 12 year blended scotch. The box says that the main SM Scotch in the blend is from the Dalwhinnie. I do like the Dalwhinnie 15 year. Although, I feel quite certain that the Dalwhinnie SM base for B12 is not the same as the D15, it still makes me curious about this blend. Whose tried and what do you think? Tasting notes?
