How does the 12 yo compare to the 7.5?
...having tasted through the line...
The 7.5 is more apple-y and tastes more like a whiskey. The 12 year old is more brandy/Cognac-like and the apple flavor is lost a bit.
I think the 7.5 yo is the best bang for the buck in the Laird's Apple line, as well as the most versatile. The most apple flavor whilst retaining that American whiskey character that works so well in a cocktail. The bonded is great for mixing too, but moreso in a drink that has more mixer(s) in it because it's so strong.
If you just want to sip it, the 12 yo would be a great substitute for a Calvados. I suspect it would make a righteous tasty Applecart if one enjoys Sidecars.
