Why Choose Ethanol over CO2?
- CO2 is synthetically made in a lab where Ethanol is made with yeast in a fermentation process like the alcoholic beverages you consume
- You can NOT charcoal-filter CO2-extracted crude. The viscosity is too thick which leaves in many unwanted materials and provides a less than desirable taste.
- Ethanol has a higher extraction yield, so you receive more product for your processed flower
- Ethanol extraction provides better storage limits
- Ethanol is considered a fuller plant extract. It extracts more compounds than CO2
- CO2 is more likely to extract chlorophyll which is NOT wanted
- Ethanol helps form esters, which lead to a more stable product
- Ethanol can produce pure terpene fraction (maintains terpene chain integrity)
- CO2 needs to use ethanol to winterize out fats and lipids, many CO2 facilities use lower-quality ethanol for this. We use high-grade ethanol for extraction
- CO2 can be fine-tuned to extract specific compounds, however, this can be met or exceeded by ethanol extraction with filters and distillation.
