We have a splendid shop in Glasgow - The Good Spirits Company. Sells stupendous varieties of whiskey (and other spirits obviously). I bought my mate a 40 year old Armagnac for his B'day last year and for the previous christmas a slightly expensive bottle of 17yr Japanese Suntory Hibiki (I think).
Bought my cousin a 700ml bottle of Bunnahabhain 12 y/o for his birthday recently from the Good Spirits Co. Last bottle of whisky i bought for myself was an okay but way overpriced Oban 14 (uses caramel colouring which is ashame but typical Diageo) and a bottle of Adnams First Rate Gin which is excellent quality spirit. Pretty much anything known to be consistent, unchill filtered and has no colouring is a good whisky. Not all blends are shit i mean big peat is a good blend and so is monkey shoulder but those are only made up of a select few malts not the 100s of malts and grain whisky in your average supermarket special blend. Most good whisky is 43% and above, something like Jura and Highland park are acceptable 40%ers.
Want something unique, look out for Signatory as they take a variety non bottled malt whisky and bottle it themselves. Some malts are only made for use in blending and these companies buy a few casks as the big conglomerates tend to make either extra or simply don't need all the whisky just a portion for their blend and sell the rest off.
Nah man the quality of the spirit is most important otherwise id be drinking watered down turpentine. Have no idea what the fuck alcohol proof is even worse is American shit is totally different even with the same moniker for measurement. All round better to use metric and everyone can understand it.
I'm pretty fed up with buying 700ml bottles because i don't get through them fast enough and it gets boring to drink the same thing, less opportunity to try new shit and even worse if you buy a random dud.
