I would like to make some of the cocktails described in this wine merchant's brochure from 1934.
But I don't know what "F.P." means in the given cocktail recipes and I can not devise a search term which gives me useful results.
I suspect, from the context, that it means something like "Your Preferred Brand".
What does "F.P." mean?
Here's an example (the link above is to a scanned document, hence not not easily copied):
**
Port Whine Cocktail
** Dans un verre à mélange; mettre quelques morceaux de glace - 3 traits de Bitter - 2 traits de Curaçao F.P. - Finir avec Porto Rouge F.P. - Remuer et passer dans un verre à Madère - Servir avec un zeste de citron.
