Winterization

Winterization is the process of purifying hemp extracts to remove unwanted fats, waxes and lipids. The concentrate is mixed with ethanol and frozen to separate unwanted components, which are then filtered out. This step is often used with BHO and CO₂ extracts to achieve a cleaner and finer end product. After winterization, extracts have a better consistency and less harsh taste when dabbing or vaping.
