(For a non islay smokiness - HIGHLAND)
Aberlour a'bunadh batch 14 59.5% 0.75
(For when in the mood for a sherry monster - SPEYSIDE)
Dalwhinnie 15 43.0% 0.75
(Soft & refined, for when in the mood for a light dram - SPEYSIDE)
Highland Park 18 3 x 333ml set 43.0%
(For the honey, the smoke, the heather, the overall quality of this fine dram - ISLAND)
Port Ellen 1979 Cask 60.7% 0.35 G&M
(Fab dram - drink it while it's possible to replace it. - ISLAY)
If I were to disregard your criteria and just go for favourites, the list would be:
Ardbeg 17 43.0% 0.75
Ardbeg 25 Lord Of The Isles 46.0% 0.70
Balvenie 21 PortWood 43.0% 0.75
