Why aya degrade after faw months in the fridge?

[Fractalus]

cooked 2 different medicine from 2 different sources and after few months in the fridge its really lower its potency, and the medicine that's come from the jungle seems to stay potent even after a year...

maybe its because it was from dry herbs vs fresh in the jungle...i don't know...
it was good after the cooking but degrade after a while.

no vinegar was used, and multiple people feel the same thing so its not a subjective feeling.

any guesses why this thing happened?

Maybe it has to do with sludge.

If you have two bottles of the same brew, and you filter the first, then it will become less potent than the second one. Sludge is always very concentrated and strong.

2 Different brew on 2 Different bottles...i guess it wasn't concentrate enough when put in the fridge' but any other suggestion will be accepted
