'Sous le manteau' is a French expression that appears in the 17th century in the world of literature, to designate prohibited works or objects circulated in secret, ‘under the coat’, because of their licentious or controversial character.

Over the centuries, these recipes have been passed on by stealth, 'under the coat'. Grimoires of alchemists, magicians, abbeys, and pharmacies have kept their traces.

One of these precious books crossed paths with Olivia Bransbourg and gave birth to Sous le Manteau in 2016. Her desire? Revive the spell of these essences.
