And an inline carbonator requires extra tools, however balances the 2 different strategies to create a purposeful compromise.

Earlier than You Start

Cons

  • elevated threat of overcarbonation
  • the additional strain will increase the chance of CO2 leaks
  • it’s slower than the shake technique
