So I recently purchased all the required toys to start serving beer on nitro (tank, regulator, stout faucet). In researching how to serve I've come across a lot of conflicting ideas and tips.
I understand that ideally you should use a mixture of nitrogen and CO2 (roughly a 75%, 25% mixture from what I've read). This allows you to keep the beer carbonated and served at the same time.
However, my local gas supply store does not carry this mixture readily. They can get it but it's like a month waiting time.
So I came up with this idea (picture below):
I would keg my beer and carb to around 1.9 volumes with 100% CO2. After it is carbonated I would put it into my kegerator hooked up to this design. The idea would be to use the isolating ball valves from each line to serve while maintaining carbonation when not serving. Open the valve to nitro to serve, then close, purge, and open to CO2 when not serving to maintain my carb.
Would this work or am I totally missing something?
