We use N-Butane for our extractions due to its unique ability to attain a richer terpene profile compared to other solvents. Using our closed-loop extraction system, we push ice cold butane through frozen cannabis, extracting all the beneficial cannabinoids and terpenes we want, leaving behind the impurities we don't.We use N-Butane for our extractions due to its unique ability to attain a richer terpene profile compared to other solvents.
