ORGANIC ALL NATURAL TERPENES With a THC content just over 90% Sovrin Extract’s THC Distillate is one of the most potent products on the market. It contains no PG/VG/PGE and no artificial colours or sweeteners. Sweet Mint Sovrin Extract distillate is made through a BHO process and their distillate is done on a short path extraction method. The Sovrin Extract vape pens use distillate and a small amount of natural plant-derived terpenes. The terpenes are mixed to create a flavour profile as close to the plant as possible. Through using non-cannabis plant terpenes, it helps maintain a consistent flavour across the different batches. When growing cannabis the flavour will vary slightly depending on the growing and drying/curing conditions, affecting the taste in the pen.
