I voted for the 12 year old, simply because I have drank more of it than other espression. My daughter just returned from a 10 month stay in Japan and brought an 18 year expression home for me.
I had my first dram this evening, and although I had read some less than glowing notes on it, I was impressed.
Nose: Peat, an undertone of citrus and just a hint of flat water;
Taste: Lovely sweet fruit opening, mild peat and lightly smoked fish, then comes on spicy in the finish;
Finish: Medium long, lingering sweet fruits, over taken by a peppery spiciness. The peat, does not play much role in the finish, but more in the middle.
Not as aggresive as the 12 in my memory, will taste them beside each other later, perhaps this week.
