I used to drink a blended Canadian. As my taste and disposable income changed, I went with Crown Royal. Generally straight up. A friend introduced me to Bourbon of which I managed to partake of many bottles and varieties. I visited a number of Bourbon distilleries including Maker's Mark. Dipped a couple of bottles myself like Hillary Clinton did. Then found Scotch, or better put, malted single malt.
While Scotch is the number one whisky of choice in any and all varieties, there's many other countries that make a malted whisky and many worthy of a taste. I do prefer Scotch but Wales has Pendrose, a couple of nice ones from Japan, and then there is Ireland.
Oh, and there is enough variety in Scotch whisky there really isn't any reason for any other. Single malts are better than blended or vatted but Famous Grouse beats Johnny Walker every time.
And I haven't given up on Bourbon either. There's a nice new one worth trying called Angels' Envy.
