Looking for the best way to nitrogenate a beer
I have a high pressure tank rated to 45psi and I’m wondering what the best way is to nitrogenating a beer. My understanding is that the beer should be carbonated to a volume of aprox 1.8 (vol) and then introduce a mixed gas (25% co2 and 75% N2) at aprox 35-40 psi. and then let it sit for 2-3 days. My question is; Would it not be better to use a “Stout gas” (20% Co2 – 80% N2). I will also be using a 4inch carbstone during the process. I was going to filter the beer first and nitrogenate immediately afterwards. My reasoning for this is that I believe the carbonation level will be lower after filtration.
I’m thinking of using a 20% Co2-80% N2 gas mix and adding it to the beer slowly, right after filtration through a 4” carb stone until a pressure of 40psi is reached..
What I don’t understand is if I want the beer to have a 1.8 Vol of C02 why carbonate in the first place if I'm adding C02 later as part of a mixed gas ?
I will edit this post later as I don't think I have made my self clear.
