Cognac oil is native to France and is part of the Vitaceae family.
It is extracted by steam distillation from dried, fermented grapes. It is distilled to produce brandy, where it is separated from the residues created during the manufacture of the alcohol.
Cognac oil is pale yellow to green with a very strong, alcoholic and fruity aroma. In the past, green cognac oil was the result of using copper stills to distil the liquid. Now, companies add the green in artificially in order to fit their customer's expectations!
The main constituent in cognac oil is ethyl pelargonate. It is used mostly in flavours and perfumes to give a subtle fruity note.
