Re: Repeat Purchase Percentage
The horizon is as broads as you want, Scotchdrinker!
From lighter whiskies from the "Lowlands" to the rugged, peaty , smoky Islay giants, there's soooo much to experience! From "official bottlings" to single cask independent bottlings...from "standard strength(40-46%) to cask strength( up to 64%) From unfinished whiskies like the Gelnmorangie standard(I see you like the Glenmorangie Portwood. this too was one of my early favourites - too bad it's discontinued|!)...to "sherry monsters" like the Aberlour Abunadh, matured exclusively in sherry casks and bottled at@ 60% abv...
Glenmorangie have a replacement for the Portwood, a little stronger at 46%, which you might try, called "Quinta ruban". I actually preferred their original...but in the same range is the excellent, rather sweet "Nectar D'Or" finished in "Sauternes"(sweet 'pudding' wine) casks, and the "Lasanta" finished in "sherry" casks.
It's a jorney which can take you in many directions. Highland Park, especially the 18, is highly thought of, but if you don't like Oban and Talisker, it may not be to your tastes...though in time your tastes will change.
It's worth giving your tastebuds a shock with a dram of the "big three" peatmonsters from south Islay - Lagavulin 16, Laphroaig 10, or Ardbeg 10 at some point, just to see what's out there at the other end of the scale...but take it slow! Beneath the medicinal, iodine-y maritime flavours lie subtle sweet or citric notes...and a clean, reassuring finish that sometimes lasts 'til next week! Not "easy drinkers" to begin with, but fascinating nonetheless!
Whatever you end up liking, there'susually a cask strength version, or something close, available.
Also, from your preferences so far, I would definitely recommend the Glenfiddich 15 "Solera Reserve." The best easily available 'fiddich..and a lovely round, sweetish balanced dram. Easy, and classy!
