If you have aromatics you (and your wife) enjoy, you might want to stick with those, and try a new one now and then ... or not. If you want to play around with getting into tasting other tobaccos, just for curiosity, get two or three one-ounce bags of bulk, maybe one Virginia like McClellands 5100, and one burley like Lanes Burley Without Bite, and smoke them now and then as a change of pace, take them slow, and see if you can pick up on their tastes over time. I don't think you can force yourself to taste anything, but over time it might kind of dawn on your taste buds. I don't think you can work real hard at this. It's supposed to be a pleasure, so either it will kind of occur to you, or you can stick with your aromatics and enjoy those. You're the "king" of your pipe, so whatever pleases you is what you need.
