The uKeg 64 (half-gallon) and uKeg 128 (one-gallon) can be used to force carbonate homebrew & other beverages. Force carbonating a half-gallon of homebrew to 10 psi would require about 8g of CO2. Then, another 8g of CO2 would be required to dispense that beer from the vessel while maintaining the desired pressure. Thus, a total of 16g of CO2 is needed. Similarly, 33g would be needed to sufficiently force carbonate and dispense a one-gallon batch, without needing to remove the cap to replace the cartridge, and expose your brew to harmful oxygen.
The uKeg cap is interchangeable and will fit either the uKeg 64 or uKeg 128. We’ll also be offering extra 16g and 33g cartridge holders so larger CO2 cartridges can be used to both force carbonate and dispense in one swoop. The uKeg 64 will ship standard with an 8g cartridge holder, and the uKeg 128 will ship standard with a 16g cartridge holder. Additional sized cartridge holder accessories will be available via our website following our Kickstarter campaign and before uKeg rewards ship in May & June.
