How to tell if compost tea is ready?

Properly brewed compost tea can be recognized in several sensory categories. Finished tea has a robust, earthy aroma similar to that of forest dirt after rain. The appearance resembles dark brown, similar to weak coffee. Aerated teas develop thick creamy foams, indicating dynamic concentrates. I can tell when it is ready based on a combination of smell, sight, and bubble activity.

Perform some simple tests before applying. The smell test is immediate feedback. Foam consistency is an indication of microbial health. I perform microscope checks every week and monitor the density of bacteria. The ideal time to brew the tea is when the pH level is between 6.5 and 7.5. The temperature of the brew determines how quickly it brews. Changes in the temperature can influence your seasonal expectations.

Tea's effectiveness is also related to timing. Aerated tea should be used within 4 hours of preparation, while non-aerated versions remain effective for up to 12 hours. I plan to apply my tea early in the morning when the leaves have the best chance to absorb it. The longer you wait to use your tea, the less microbial population will be present. Store temporarily in shaded containers.

Troubleshooting issues in home brewing. Lapses in the aroma of the brew indicate that you need to brew the mixture for a longer period. Add a tablespoon of molasses if foaming does not occur. Any Coudiness means to filter it through cheesecloth. My success rate improved after I logged temperature changes throughout the brewing process. Maintain the sample temperature at 55-80°F.
