With whiskeys and people who like them, there is no accounting for taste. Everybody likes what they like, and I like bourbon. Kentucky straight bourbon, ten years old or older. Jack, Jim, and low shelf others? Dont bother. Surprisingly, I do like the taste of some very cheap whiskey like McCormick, and Evan Williams. I like Heaven Hill products.
Scotch tastes like dirt to me, but I will drink it, if I have to... I gave away a bottle of rye and wont drink it if you paid me. Just dont like the spicyness.
Irish and Canadian whisky dont have much experience with so cant comment.
And now, I will tell a true story. When I was working in Kosovo, we used to stop at a mom & pop convenience store for beer, smokes & booze. One guy got a bottle of (believe it or not) Southern Comfort. I guess made for export? This bottles was label dated 1986 so it was sitting around for 25 years or so...
Now, people say whiskey stops aging and maturing when they bottle it, but I have my own opinion about that. Normally I would classify Southern Comfort as one step above cough syrup, but this particular bottle was absolutely superb! Old whiskey really is better than newer whiskey, even the same stuff, and I would invite comments on this idea.
Also, I have friends who take low class harsh newer whiskey and put it in wide mouth glass pickle jars with oak sticks that have been baked and then charred and let it sit for a year or so. Depending on the wood, it will improve dramatically. With fresh white oak, after one year it will taste and smell like chainsawed firewood. But take the wood out and let it mellow another year and it smoothes out and smells like vanilla, spices and can be very nice. With whiskey, nothing can replace time and oak.
