We use small-batch, CO2 extraction and test continuously throughout the process to ensure that the final extract delivers the purity, potency and phytochemical composition that our customers demand. Small batches allow for rigorous quality control, and CO2 is a much safer, cleaner technique than solvent-based methods, which require additional post-processing that degrades the quality of the extract (while still leaving trace amounts of solvent). While CO2 extraction demands more expensive, sophisticated equipment and expertise, we think a cleaner product and a cleaner environment are more than worth it.
