I like to think I am eclectic whisky drinker verging on being what Karloff describes.
I have kept trying bourbon even though I struggle with it but there are some old ones out there that are really good and a recent Blanton's I tried was also nice so need to keep going on that score.
I have tried plenty of grain but it does not match single malt for the experience, on the subject of blends, I have had some real rubbish but there are some absolute gems out there that for taste can match any single malt, well almost any single malt anyway certainly better than some of the overpriced stuff about these days.
I think you do need to explore what is on offer out there because in all streams of whisky, even the ones you do not like there is always something.
I like to try whisky from all distilleries, especially unloved ones as from time to time some great casks emerge, Fettercairn, (only one so far) Macduff, Speyburn, Teaninich, Inchgower, Brackla etc etc .
Variety is the spice of life, if I was a snob in some way as Ganga asks it would be for closed Distilleries, I have had bottles from them and samples , closed distilleries like North Port, Hillside, Coleburn are getting really scarce, soon the opportunity to try them will have gone forever and that style of whisky making to try also lost (a great shame)
