Is it necessary to stop fermentation before capping bottles of Kombucha Tea?
Some people leave the Kombucha Tea ferment longer than usual to avoid the carbon dioxide gas that tends to build up after the bottle has been capped, hoping to avoid broken bottles. Others prefer to let the carbon dioxide build up; this tends to make the beverage more effervescent. If you are worried about glass breakage you could use a cork instead of a screw-on cap, this way if the pressure builds up too much the cork will be forced out of the bottle and the CO2 can escape.
