Extraction methods matter. And ours are the best.
Straight Hemp uses the widely-recognized top extraction method, Subcritical CO2, which takes place at cool temperatures and low pressures. It is the slowest of extraction processes, but the result is an oil that preserves many more cannabinoids and terpenes, for better taste and maximal "entourage" effects. We clearly notice the difference, and we’re sure you will too.
Another option is to use Supercritical CO2 extraction which takes place at high temperatures and significantly higher pressures While it’s a faster method, oftentimes it includes bitter by-products, and many terpenes are destroyed: Think over-steeped green tea.
For that reason, we never use the Supercritical CO2 extraction process.
| SUBCRITICAL CO2 EXTRACTION | SUPERCRITICAL CO2 EXTRACTION |
|---|---|
| Lower pressure/lower temperature | Higher pressure/higher temperature |
| Preserves terpenes | Sensitive oils evaporate (fewer terpenes) |
| Leaves behind bitter compounds, wax esters, etc. | Extracts bitter compounds, wax esters, etc. |
There are traditionally 3 major types of extraction, which depending on how they are used, and the type of input material, influence the extract quality. They are alcohol, CO2, and hydrocarbons. Up until now Straight Hemp has used a subcritical CO2 extraction method because at the time it was best in class, allowing for maximum extraction of essential oil Terpenes, and CBD while preserving the taste and leaving behind all the undesirable plant waxes and cell wall parts.
