This thread is fun. So on the topic of cellaring...
So I switched from cigars to pipes about a year ago. I found a well-recommended blend that I really liked (FMC), and as I neared the end of the tin and went to re-order, found out that it was no longer being made and the company went out of business. Then I heard of the deeming regs for the first time...
So my first year of pipe smoking has been characterized by trying small tins of well liked blends and if I find something I really like, grabbing a little bit extra. Something that I try and LOVE I might order a few pounds to cellar. Right now I'm sitting on about 25 pounds. Most of that is bulks I like and got on serious discount and want to get some age on it. I probably have 5 pounds of PS LBF after that last sale a few weeks ago. But my main emphasis is to find out if I like a blend enough to cellar deep because it is going to be affected by the deeming. For example, I love Chelsea Morning and Plum Pudding. So whenever I can get 8oz cans on sale I grab a few. I also love GLP Westminster, but it came out before the arbitrary date, so I'll grab some of that after the hammer falls.
So in summary, I guess my cellaring is in part for aging, and in part for future scarcity. Right now, there's only a few blends that I "can't live without" and will get affected by the FDA so I'm focusing on them. In the meantime, I'm still trying out a bunch of new stuff and trying to enjoy the last days of the "golden age".
