Insider knowledge: Glengoyne 21 Year Old whisky is named whisky by virtue of the fact it's from Scotland. If distilled in America the spelling would be Glengoyne 21 Year Old whiskey, as opposed to whisky.
Nose: Oak, barley, red fruits.
Palate: Barley and oak, possibly erring on the side of too much oak. Winter spice, cider.
Finish: Oak, barley.
...17y is good,but this one is worth the extra money! WONDERFUL!
I read a review saying that the 17 year old was better and that I should ignore the 21-year old. Having tasted it I can only say that that review was wrong. The 21-year old is too different to compare.
The 17-year old is smooth and easy to drink.
The 21-year old is a lot more warm and complex, a bit too much oak and a bit dry, but if you like that, then it is perfect.
Matured in sherry for all of it's life. That's rare and delicious
