As a man who drinks whiskey fairly regularly, mostly Irish but some Scotch, and who had drunk most Irish whiskies,
I think that there are 4 really good Irish Whiskies which are reasonably priced.
Tyrconnell Single Malt.
Powers 12 yr old
Jameson 12 yr old. Jameson 12yr old distillery reserve, which can only be bought in the Distillery, is even nicer!
They are all subtly different.
Connemara, which is peated, is lovely when I'm in a certain mood, and other times it does nothing for me.
In cheap whiskey, Paddy is lovely with ice, but only with ice, Powers is good, Jameson ok, Kilbeggan good, Original Bushmills lovely and I don't like Black Bush (I don't like Glenmoreangie either).
In Scotch, I've most liked Lagavullin, Arran, Leapfrog, Glenkinchie and in the cheaper ones, Teachers, the Low Flyer and so on. The Best to my taste though (I suppose because it tastes like irish) is the Macallan.
