I'm up to over 30 cans in the fridge already, and have still more on order since I'm only about halfway through the list of everything Northerner has that I want to taste.
But look on the back of your tins, and you will find an expiration date. My General Onyx says "Best Fore 22-07/2009" (I presume that means July 22nd) my Nick & J West says "Bast Fore 01-06-09" (yes it is apparently expired) and my Thunder Frost says "Bast Fore 30/10: 2009" which I guess is the day before Halloween. I understand from people who should know more about these things than I do that the "best used by" or "bast fore" dates do matter. They are a perishable product that really does go seriously bad eventually, from what I've read, and that date assumes they are refrigerated. Looking through the date stamps on a bunch of them, I get the idea at least some of them can keep (chilled) for as long as six months from whenever they were made.
But my understanding is that they keep a long time if frozen, preferably in an airtight container so they don't dry out. So I guess my drill should be to keep most of my stock frozen, with a few tins in the fridge, moving a new tin from deep freeze to chilled storage as I use them. But I must try a few of each first, you know, so I haven't actually frozen any yet myself, only keeping them in the lettuce crisper so far. I also got the idea somewhere that they can benefit from being kept in a container with a little moisture added to it once in a while to keep from drying out in the fridge if they are there for more than a week or so after being opened. Makes
sense to me, and I have some little water absorbing
devices that I got long ago to hydrate bulk smoking
tobacco, but I imagine a little piece cut off of a sponge or something like that would probably do the job.
Or, you could probably cure yourself of this thing for a while by choking on a vile Marlboro "snus." And those, suspiciously enough given their bizarre chemical taste, are the only snus I've found or heard of so far which are NOT kept chilled before sale. Hmmmm.
