Allthough the difference is only 0,5% in Abv, the 800066 is way more influenced by alcohol, especially in the nose and body. Only in the finish, alcohol starts to work for the 800074, which makes it more smooth and softer than 800066.
In nose and taste itself, both whisky's are quiet similar.
Sweet, vanilla, flowerish, fruity. Fresh apples and citrus.
Only slightly pungent, pretty full body, sweet, vanilla, honey, caramel. Some fruits as well, like peach.
Pungent and sweet, still some caramel, vanilla, long, a little bitterness now, and still some apples.
