Mixing/Degassing
Agitating the unsettled contents of Better-Bottle carboys in order to mix ingredients, add oxygen, or remove CO2 is very simple and, in contrast to glass carboys, no special equipment is required. If the wine or beer has already been settled in preparation for racking, slapping the side of the Better-Bottle carboy will cause shock waves that will drive CO2 out of the liquid and hasten settling of low density suspended or clinging solids – without significantly disturbing the sediment on the bottom of the carboy. To prevent oxygen contamination during degassing, carboys should be closed or equipped with a DryTrap air lock. Use the DryTrap tab to the left of this page for detailed information.
A Better-Bottle carboy can be placed on a cloth or towel and rolled back and forth to slosh the contents vigorously with very little effort. Leave extra head space during initial mixing and aeration to maximize agitation.
Swirling or rocking a Better-Bottle carboy vigorously requires almost no effort, if a tennis ball is placed in the punt space under the carboy. Leave extra head space during initial mixing and aeration to maximize agitation. To avoid wearing the bottom of the carboy, perform this operation on a smooth or soft surface.
