The Art and Science of



Worm teas are a product of vermiculture, or the raising of worms. Earth worms, specifically Red Wigglers, are particularly adept at breaking down plant matter. Their excretions (manure, or just plain poop), becomes highly enriched with nutrients through this process. It's pretty simple. Trim healthy plants, and feed those trimmings to the worms, and their poop will be filled with the very same nutrients those plants used to succeed in the first place. The worms also eat around (or pass) certain nutrients which are indigestible yet highly valuable (such as certain minerals). 

This poop is called a "casting", and by dissolving the contents of casts into a liquid solution, we create the beginnings of a worm tea! Other steps are necessary for the final product, including aeration to encourage bacterial cultures that aid in root systems, among other steps, but you get the picture. The result is a highly nutrient rich, easily applied (and odorless!) soil amendment with none of the downsides of nitrate-rich mineral fertilizers or the health concerns of traditional manures. Simple, sustainable, effective.

If you're interested in learning more about the science behind vermicomposting, we've compiled a list of publications here that describe the results of experiments on vermicompost teas and similar compounds to WriggleBrew. We've also added some of the graphs and tables from these experiments to give you a better idea of the metrics behind this potent soil amendment. Finally, we've added photos of our own experiments with this brew, in case you were interested in seeing how we've used it ourselves!
