750mL Cork-Finish Belgian Beer Bottles

I was wondering if anyone knew of what CO2 volume that 750mL Belgian-style cork-finish beer bottles with wire bailers will handle? I’ve seen it listed at both 3.5 vols and 4 vols. I’m planning on bottling up a Belgian Quad for extended aging.

Thanks

Can’t give you numbers, but they’re heavy bottles, and those corks really hang on.

Probably over 4.0. Regular beer bottles will hold 4.0.
IDK if you want to carbonate higher than that but you could in the Belgian style bottles.
