The reason for asking about quantities of raws being ordered is because of the popular saying here: A source is only as good as their last batch of raws. While they may have always done you right with their purity, knowing full well what you’re putting out goes a long way. In the long run, it not only serves you, but the community. The stuff that was bought and is being sent for testing from the person who bought is only going to prove that batch is good. Future batches of course are dependent solely on the new raws. Obviously if you buy a kilo at a time and that kilo tests good, you SHOULD have quality batches for what that kilo produces - granted that you know what you’re doing when it comes to brewing.
