I am doing small batch BIAB (2 gal ) indoors during the winters now and bought a carbonator cap.
I intent to use either 3-4 2L bottles or a few 1L’s to “keg” my trial 2G batches using the cap to add CO2.
My question is for anybody keen on math or prior experience doing this specific function.
I tried doing an extra bit of my last 5G batch into a 1L and added CO2 via cap to cold wort for about 2-3 days at normal keg pressures of 11-12 PSI.
Although it had some carb it didnt seem fully carbed, do I need to keep 1 or 2L bottles on gas 1-2 weeks like my 5 gallon kegs to get proper CO2 in solution or should it only take 1-2 days each time I want to carb up to fully saturate the CO2 to 2.5 ish volumes I would like.
Also I understand well I could play around with 20+ psi etc… But I like to set my “kegs” etc… to normal serving pressure to ensure correct carb everytime not high/ low depending on.
