Working out scale
As to a malt, I agree with your area choice. I have a bottle of The Talisker, bought for me by a grateful customer who travels a lot. I haven't had customers for a couple of years, so you can see how much of it I drink!
For a simple tipple, I prefer a Navy rum, like Pussers or Woods and to make the Woods last longer, but not noticeably change it's flavour a drop of peppermint cordial with it. An old Fenny put me on to that trick.
But a smal heart attack at Christmas 2016 has made it necessary to be a bit careful with the imbibings and it goes in small measure in a coffee these days.
Cheers,
Martin
