I have 7 jars on the shelf and a pouch of 5 Brothers always at the ready ,
I try to just keep a nice variety of all the families going for when the mood hits.
But I mostly smoke 5 Brothers and Peterson Flake with the occasional Oriental for some spice.
Eight: Bayou Morning, Bayou Night, Bold Kentucky, Old Dark Fired, Nightcap, Quiet Night, Brebbia Balkan, Old Joe Krantz are in my normal rotation. I smoke other blends as well, but just a few times a year. Although my most smoked tobacco is Bayou Morning, I can't get enough of it. Before it was only my Summer (or warm weather) blend, but it has grown on me.
I only have jars/tins that are not open because they are back up inventory to what I already have an open jar of. I don’t faff about with buying and hoarding tobacco to age. I’m new enough I’ve only got a couple/few dozen blends but all are “available”. Inventory increases on blends I find I like, as a function of “stocking up” on what gets used more (or blends I know I like that have more limited availability).
For me it’s not complex, pretty much like anyone’s kitchen pantry-there’s more of what gets used more and less of things that don’t.
As for true “rotation”, that’s more like my work week. I carry four smaller repurposed Snus tins in my lunchbox that get stuffed with an ounce or so each of a variety of what I’m into at the moment on Sunday night. I’ve got masking tape labels with a tab folded over on one end that get peeled off side of jar or back of tobak cabinet door and stuck on tin. Unsmoked tobacco will get dumped back in its jar to rebalance its hydration, except straight VA flakes-any scraps of those at the end of the work week get all dumped together into an ongoing tin labeled “flake shake” that gets grabbed from often, and has become a favorite to grab from because it’s always interesting and never bad.
3 on a regular basis: a VA, VA aromatic, and a burley blend that changes summer to winter. Then a few others for a change of pace, maybe half a dozen. Then some old ones I never reach for I've been meaning to toss, but haven't been able to, they just may come in handy some time.
I don't smoke a lot of one particular blend. I like variety. In general, I will only have 2 ounces of any particular blend open at a time.
I have about 40 jars in my cellar that I will dip into. I have a lot more blends in the backlog waiting for their turn in the jar.
I like that number. It's a wide enough variety that I have a lot of options, but it forces me to go back to those jars until they are empty. That way, I feel like I can really dive into a particular blend and get to know it. By the end of the jar, I'll know if I want to re-up or not. And if I think it's a dud, I'll pass it on to make room in the cellar to open a new tin.
