Black Barrel contains a significant proportion of pot still whisky (75% from what I’ve heard). Although an NAS whiskey, it puts Bushmills 10 to shame. Beautiful notes of caramel and vanilla sweetness from the bourbon barrels combined with a juicy dark fruit aroma and flavors from the sherry casks. The mouthfeel is surprisingly chewy. My only complaint is from the low abv of 40%. I actually consider it to be my runner-up to Redbreast 12. Excellent value from a truly underrated Irish whiskey!
