Aging a straight Virginia couldn't hurt for the Red Cake. Lane 1Q being an aro IMHO wouldn't help much if at all. In fact you may find over time that the flavorings may dissipate.

When I "jar" pipe tobacco I take the jars right out of the case and use them. So far in 15+ years no adverse effects. When I change blends in a jar, I do run them through a hot water wash cycle in the dish washer.
