Botanical source

Myrica gale is a small shrub growing in northern hemisphere wetlands, Scotland, Scandinavia, North America, Russia.

Traditionally used as a beer flavoring ('gruit') before hops became widespread.

Family Myricaceae, not Myrtaceae as the name might suggest.


Notes

Very small-scale, niche production. In perfumery, bog myrtle contributes a cool, green, slightly piney note.

Traditionally used in Scotland to repel midges and mosquitoes.
