For what it's worth, I recently did an experiment and collected samples at various points in time during the cure, and put them in the freezer in vacuum sealed sous vide bags.
Samples were all taken from the same plant and were curing in jars a very strict environment of 70 degrees at exactly 62% humidity.
It started off with a typical 5 day hang dry. After that, buds were trimmed and jarred.
Samples were removed from the jars, placed into sous vide plastic bags and vacuum sealed and immediately placed into my garage freezer inside of a cardboard box.
I took samples at the following intervals once in the jars:
- 2 Weeks
- 4 Weeks
- 6 Weeks
- 8 Weeks
- 12 Weeks
- 16 Weeks
- 24 Weeks
I then passed out samples to all of my friends and it was pretty unanimous. Here were the results:
There was no noticeable difference between the 2 week and 4 week samples. Visually, the samples looked great still. The taste was good, but not complex.
There was a noticeable difference with the 6 week samples. Visually, the samples still looked very fresh and had not begun to darken. The taste was noticeably different, however. More complex. More refined. It was also a bit stronger.
There was not much of a difference between the 6 week and 8 week samples. One person reported an additional bump in the taste complexity but I screwed up and he knew what he was sampling so I don't count his review.
The 12 week sample was noticeably different from the 8 week. It no longer had that nice visual freshness. It was considerably darker and, while still looking great, it did not look as nice as the others. The taste was only marginally different but the inhale was noticeably smoother.
The 16 and 24 week samples continued to show declines in appearance and smell. These no longer had the bag appeal and the nose just wasn't there any more. No real improvements in taste.
My conclusions:
A 6 to 8 week cure is optimum without sacrificing appearance.
