Compost Extract Bag

The TeaLAB Extract Bag is a professional-grade tool designed for producing high-quality compost extract and vermicast extract at home or on-farm scale. Constructed from 400 micron nylon mesh with climbing-grade binding, this bag is engineered for strength, durability, and repeated heavy use.

Each bag is hand stitched in Seattle, USA, by a specialist cut-and-sew workshop known for producing high-performance backpacking gear. This level of craftsmanship ensures a long-lasting tool that can withstand repeated loading, agitation, and brewing cycles without breaking down.

The fine mesh allows beneficial microorganisms and soluble nutrients to move into solution while keeping coarse material contained, making it ideal for brewing biological extracts that can be applied directly to soil or foliage.

The included carabiner clip allows the bag to be easily suspended in a compost tea brewer, ensuring consistent flow and aeration during extraction.
