So somehow I made a doofus mistake. After force carbing for 30 hours at 30psi and purging the keg I dialed the pressure down to 13psi but somehow forgot to open the CO2 valve. Don't know how this happened as I even checked the next day and can swear the valve was open. So anyhow, I reset it to 30psi this morning figuring maybe 12 hours or so to make up for some of that lost time. Questions are: 1. Should I just do more time at 30psi or would that equal more than 2.5 days at 13psi? And question 2: I doubt there would be any negative affect on the beer at such low pressure since it was still under CO2 and the beer will off-gas some pressure (plus it's at 36F), but is there any chance of negative affect on the beer other than loss of CO2 volumes and more time needed to get back to where it should've been after 2.5 under 13psi?
