According to Greg Pease (and what does HE know!) Virginia and Va-Pers will age best. The high sugar content in Va tobacco aides in the aging process. Va's will age well beyond their 20s and 30s. Lat/Orientals are good to around 10-15 years, with the Latakia starting to fade after 8-10 years. Burley has very little sugar, so while it won't "age" it stores well...there's a difference there. Most of your "flavored" tobaccos...those with a lot of cherry/rum/chocolate/vanilla toppings...will not hold up to long term storage. The toppings will actually sour after a few years. This is of course, pointed toward long term storage. If you plan to smoke it before the 3-5 year mark, anything will "store" well for that long.
