does mature weed improve like a wine?

I found a few old jars of Blueberry and Jack Herer the other day that are about 18 months old. Question: Has anyone else found that very old weed actually matures with age? Grows more complex in high, more interesting, more balanced, and sometimes stronger? Although neither smelled very strong, the high was really beautiful.

Im about to find out. oldest ones I got right now are 10 month and so far better than right after cure
