Here are instructions from Worm Digest:
Get a 5-gal. food-grade bucket, fill it w/water and let it sit overnight to evaporate the chlorine out. Get a mid-size aquarium pump and a few bubblers (the disk-shaped ones put out more air). Pick out several cups of your best compost, wrap it in cheesecloth, and hang it in the water.
Add some nutrients: If for vegie, row crops, lawns, or annuals, you want a more-bacterial rich mixture with food or green plant waste or livestock manure or sugars, algal extracts, or yeasts. If for deciduous trees, berries, or shrubs, you want more fungal rich additives like fish hydrolyzate, humic acids, or yucca. You can also purchase commercial tea starters.
Let this brew for several days, then dilute 10/1 with dechlorinated water. Use 5 gallons of concentrate per acre. Always use tea within 12 hrs of the time aeration has stopped (or it may turn anaerobic and become toxic!)
Tea should be sprayed over a plant's top and bottom leaf surface, preferably 1 - 2 X per month through the growing season, and as a root drench.
Vermicompost tea is even richer than compost tea. For more info., Worm Digest has Issue #27 available thru
