Since I've started smoking a pipe I've bought more tobacco than I'll likely ever smoke in my lifetime. Not because it's too much but because I've bought a lot I thought I liked, but then ended up not liking. OGS and Dreams of Kaddath being two that come to mind on that list. It took about 1.5 years to realize how I determine what I actually like. Its not a mental choice for me I don't think...it's a desire or a craving. I love the flavor of Newminster 400, bought a pound, never went back to it. Mentally I like the flavor but I can do without it and so I rarely ever grab it. My desire seems to be related to a variety of factors most of which are not really conscious. Nic hit, desirable flavor, enjoyable when sipped, enjoyable when pushed, quick to prepare, all seem to be factors that keep me coming back time and time again naturally. As of right now, there are only 4 blends that meet these requirements for me - Erinmore, Royal Yacht, Nightcap, and St Bruno. I am confident I could only smoke these 4 and be quite happy. Right now I could smoke St Bruno all day everyday, easy. I'll still explore a bit I think, but not much. And my standard for cellaring will be much more strict.
