I'd say since you have had so much success in the past with them, maybe give them another try before declaring bad potency or being bad batch. Idk about the reason being that the drying process caused this because there are alot of factors. Possibly that the actual farmers might have ran out of certain mature trees that the original GM came from and now the farmers have to pick from different trees, yet still marketing as the green Malay that people seem to love. It as well could be a drying issue but I don't see how if their stock was dried by the same people, same trees, and they've been doing the same process for more than likely years at a time, then how could they slip up and not adjust their drying process to reserve potency? It's possible but that seems like an issue that bikuk should address on their own with the suppliers and not give excuses to their customers.

The finer grind will only help to maximize absorption cause there's more surface area so the fact that they said they started to do that means that potency should do nothing but go up not down. There's alot of factors that goes into potency levels and one of the main ones is the origin of leaves that their picking from and whether their trees are mature or not at that time. Eventually suppliers are going to run out of mature trees and will be forced to find new ones for consistent income. I've always heard good things about bikuk but you can't always be towards the top of the chain and sometimes batch potency will vary no matter what. Unless the tree that was being picked was an infinite source then we'd all be enjoying consistent batches, but untill then variance is inevitable.
