A compost tea system uses a water-holding tank for containing process water. Compost is immersed into the water in the tank in baskets defining a filter media. Air is pumped into membrane disk diffuser modules in the tank and the liquid is sparged with fine bubbles to thoroughly agitate the liquid, extract nutrients and microorganisms from the compost, and to ensure a high concentration of dissolved oxygen in the liquid. The high level of oxygen selects for desired aerobic organisms to produce a rich compost tea. The finished tea is drained out of the tank and the tank and its components are easily cleaned and sanitized.
