I agree. You won't know what you want to cellar until you try it.Honestly, if you haven't tried them I wouldn't waste the time cellaring anything. If you like something a lot, then buy more and cellar it.
Oh I also reccomend smoking it in a smaller bowl because it's the only pipe tobacco that taste the same no matter if you go fast or slow or how far into a bowl you are. It's taste is constant, thank god it's got a few things going on.Rainy day is such an aromatic beast that keeping it in a jar for a month is a good idea just so there is a little bit of tobacco flavor. Good stuff but it's very heavily cased and as far as what the base is could be any leaf or even cardboard.
