Knockando 21 is a whisky that apparently is special as the casks have been resting in a cooler part of a warehouse which means it takes longer to mature...hmm ok. Not sure why that makes it special given I'm pretty sure it's the 21 years which is the factor here around length of maturity but here goes. Ok nice viscosity.. check▪one dimensional flavour (honey/toffee)..check ▪Any advance on one nope. Slightly rough for a 21 year. I can see why this is cheap for it's age. In a word unmemorable. Wouldn't kick out of bed on a cold windy night though. Just under 3.5 I'll give it..definately got better as I got into it. Vague Glenlivet 18ish profile. Not the most amazing start to my 100+ step whiskey tasting programme but not a bad one either...at least I didn't buy a bottle
