Some green Grolsch bottles, some brown misc. ones from German Christmas markets; I have a lot of 660ml Fischer bottles picked up from French supermarkets when on camping holidaya when the kids were wee. The youngest is now 35 so that gives an idea of how they last.
The Fischer Alsacian beer used to be really nice too!
( Oh dear - just looked it up in Google ... wikiP says
Fischer was a brewery in
Schiltigheim, France.
Heineken took over the owners in 1996 and closed the brewery in 2009.
Sigh.)
If you google the name and see ythe prices people are asking for the empty bottles .. I could probably get a deposit for a camper van...
