Colour: rather a little lighter.
Nose: full, heavy, hardly any cardboard, vanilla, sweetness, alcohol well integrated, no smoke, no off-notes, butterscotch/caramel. You rarely have such a beautiful bouquet!
Taste (tried diluted): Alcohol burns a bit at first, maybe there is also some pepper/chilli, almost more reminiscent of a bourbon than a sherry cask, wonderful sweetness, very slight bitterness (dark chocolate), very slight earthiness, nice spiciness. harmonious. Complex. mouth coating.
So far I have also had the 1990, 1991, 1996, 2001, 2004, 2005 and 2006 bottlings of the S21 release in my glass. All of these were not really convincing for my taste. 1990/S21 is still worth mentioning positively, but it only got very close to 90 points from me and is not a purchase recommendation. 1990/S20 was so incredibly much better. The 1994/S21 bottling discussed here is for me the best so far from the S/2021 release. So I bought another bottle. As you might expect, this isn't a sherry bomb, but a great old Family Cask with a very nice balance between cask influence and distillery character. The aroma intensity is quite high for a refill cask.
In view of the many tried and mostly only moderately good bottlings of the releases S20 and S21, I can now see a certain disappointment with regard to the Family Cask series from Glenfarclas. Prices go up while quality goes down over the years. Finding a nice bottling is now like a lottery. Most of them are not worth the price imho.
