A distillate is a viscous liquid that contains the active ingredient in its refined form. It is free from terpenes, pollutants, and other cannabinoids, so it has no smell, taste or aroma.
An isolate is nothing more than a pure form of a substance that has been separated from the remaining active substances from hemp flowers and cleaned of plant sediment. Full spectrum cannabinoid hemp extracts and terpene tend to be dark in color. Sometimes it will be golden brown and sometimes dark green.
