I never really understood kilo-size bulk extractions to be honest. 100-200 grams extracted properly can keep someone happy for quite a few months. When one extracts 2-3 kilos for himself runs the danger of his spice degrading or going bad before he manages to finish it aff. Better extract smaller amounts (if one has a big batch) while the rest of the bark can rest in the freezer for quite a long time.

Without wanting to force any suspicions around, some shady business plans always comes to my mind when someone asks questions about bulk extractions. Not that it is the case, how could I ever be sure about such a claim? Just what comes to my mind and I reserve the right to be blatantly wrong on that.
