+x Hasbun - 7/1/2019We never found anywhere in France that would refill foreign bottles. In fact, it appears to that refilling non-national bottles is now forbidden by European rules; this may explain why it is not commonly done in France. With some work, we found the rare individual that does refill a foreign bottle in Portugal and in Spain. From friends, we learned there are a handful of places in Italy that will do it as well, though we never did ourselves.In La Rochelle, Sofomarin sold us a brilliant kit, made in the UK, that allows about 15 different types of national bottles to be connected to a single universal fitting, via adapters. The owner speaks French.If you buy his adapter, in France, I recommend the Butagaz “Le Cube” bottle, made of fiberglass and soft rubber. Works wonderfully in a sailboat, provided it fits in your gas locker. Available all over France, including in Corsica, it can be had in a blue label butane or red label propane version. We used it with butane in the Med but exchanged it for free for a propane version before sailing for Scotland, as propane is better under lower temperatures.Map to Sofomarin:https://her.is/2J22DzhSofomarin:52 Rue de la Trinquette, 17000 La Rochelle, Franciahttp://www.sofomarin.com
