Extraction methods

Nine ways of getting smell out of plants, and what each one loses. The first three are all distillation, and differ in whether or not the raw material touches boiling water — a small difference in equipment, but one you can measure on an analysis.

Set all nine side by side to compare temperature, solvent and what each loses. If you are holding a bottle and are not sure what type it is, read what the words on the label mean first.
