I did a little taste /potency testing during my last cure and I found that about three weeks in a jar was optimum, for both taste and potency. One week or less was rough with poor taste and lower potency , during the second week taste and potency improved , between third and fourth week I felt like taste and potency was at peak, I went on for three months like this, and after the first month the gains from staying in jar were negligible. Taste maybe decreased potency remained the same.

Of course this is all subjective. No scientific study or anything.
