G'day,
I've got a Lager fermenting under pressure at the moment, I was hoping to carbonate as well, though my pressure gauge only goes to 15psi, and the valve itself seems to be limited to 12psi. (have to source some new parts before next attempt).
I'm at day 7, I was wondering if I'd get away with taking the spunding valve off, doing a D rest for 24 hours with keg completely sealed and let the pressure build up without regulating it. Then begin crash cooling it over following days. once it's cool and absorbed C02, whack the spunding valve back on and set to the desired pressure, and bleed off excess.
Am I asking for trouble doing this? should I just settle for partial carbonation instead? Is the worst that would happen, just over carbonation?
How many points from FG is too many to try this?
