I am not much of a "whisky" drinker, but might have to buy a bottle of the Jefferson for my friends that are.
The reason most Americans don't care for the taste of gin is because American gins taste like turpentine!
The English, despite their other faults, DO understand what gin should be. Try some Tanqueray, and see what gin is supposed to taste like. I specify the "T" for my martini's when dining out, but it is also great in a gin and tonic, (keeps the malaria away, don't you know) and we also drink a lot of it with Squirt, which makes a "field-expedient" Tom Collins.
Bombay is also very good, but a bit sweeter than the Tanqueray. Beefeaters must be the "cheap stuff" in England, as it is barely better than American gin.
