Frozenoak, I share your annoyance at opening too many tins at once. I always teeter because I have so many samples, open jars (that is, jarred blends not being aged), pouches, etc. It's a balancing act. Too much hesitancy means I end up with many wonderful blends that are held for years. Balance in general is an under appreciated virtue, maybe because you never quite know when it is attained.
