CO2 is like that deliciously fresh squeezed orange juice, whereas other extraction techniques that do not use CO2 are like store bought orange juice from concentrate. Let’s be real – it tastes way different. CO2 extraction is considered the gold standard for hemp processing because it doesn’t require solvents like ethanol, butane or propane, which inevitably leave residue behind. CO2 is carbon dioxide, just like the gas found in the air we breathe. After passing through the hemp plant and extracting all those lovely nutrients, CO2 evaporates and no residuals are left behind – just pure, nutritious full spectrum hemp extract.
