As far as your direct question we score out of a 10 point scale.
0 Truly undrinkable, actively offensive
1 Very flawed, will not finish
2 Not a lot there, not complex, unbalanced
3 Not complex, but shows some promise, more balanced
4 Good, drinkable, can have flaws
5 Performs well on some aspects
6 Very good
7 Highly enjoyable, increasing complexity
9 Malt O' The Minor Gods
10 Malt O' The Gods
The Tobermory only got a 2 which is pretty low on our scale, but not the worst. Then the 15yo gets to a 4 and the 20yo gets to a 6. At 6 on our scale you are dealing with a very drinkable and enjoyable beverage. I cannot give you any notes on these beverages, it would be a research project to find them, and it has been a while.
I would think it would be a function of price for me. The 15yo would be an okay beverage if the price was on the cheep side. And the 20yo would be okay at a good price.
