Compost Extract versus Compost Tea - What's the Difference?

Compost extract is made by flushing water through compost for about 30 minutes to "extract" the existing micro-biology into the water. Compost tea also washes the micro-biology into the water but then the water is "brewed". This consists of adding foods for the microbes like fish oil and vigorously bubbling the water for over 24 hours. The result is a bloom of beneficial protozoa in the tea.
