I don't have an everyday choice vs a special evenings drink. I usually don't open a new bottle of whisky until I've finished the current open one. I don't want to seem like too much the alcoholic when friends drop by

.....but on to types:
My everyday purchase choice is Laphroaig 1/4 cask. This one is good because it has such a strong taste that a lot of my friends don't like it - so more for me
I just opened a bottle of Cragganmore finished in a sherry cask (got it at the duty free shop in Shanghai) and it is really mellow and has a very sweet finish - it might become my new "everyday"
That said, I also have a bottle of Cragganmore finished in a port cask - unopened - also from Shanghai duty free - that one will probably be uncorked this summer at the cottage.
I wonder what the Duty free shops in Tokyo have (I'll be there in about 3 weeks).
