Do I keep draining the tea during the final two weeks of fermenting when the bucket is full and nothing more will be added?
Yes! In fact, this is the period when the most tea will be produced. Draining the tea is required in order to prevent the liquid from building up and contacting the food waste in the bottom of the bin. Also, the tea is a useful product for your garden, so its worth doing! If you have no use for the tea, then its good and healthy to pour it directly down your sink drain. The microbes are a healthy addition to any septic system, and will help clear your drain pipes also.
