I'm sure there are many reasons not to use the 2 liter bottle for this purpose, and many better alternatives. I'll thank everyone in advance for telling me those facts, but, will a 2 liter plastic soda bottle hold the beer or wine without exploding? Say if the fermentation was not complete or if it restarted?
I've seen 2 liter bottles pressurized to failure (not pressure gauge used) and they seem pretty strong. However I have no idea of the strength needed, nor any idea of what a fermenting beverage could generate.
Thanks
