Could be a simple answer. If I force carbonate too 3 volumes at 58 degrees when I drops the temp down to 37 degrees will it still be at 3 volumes c02?
It should retain it's carbonation level at the lower temperature. You'll eat up a lot of CO2 doing it at 58F though. You'll also want to check the pressure on the keg before you connect it up to a regulator for serving. If you're already setup to serve at 3 CO2 volumes, why not carbonate in the fridge/keezer/kegorator?? Chances are, you'll need to pull the pressure relief a few times on the keg once it's at temperature (24-48 hours after putting in the 37F environment). Use a keg pressure tester to see where it's at BEFORE you connect up the gas feed.
Are you saying that it will take more CO2 to carb to 3V at 58F than at, say, 35F? Maybe you can explain that.
We're talking about a measurement of VOLUME. A beer at 3 volumes at 58F will still have the same volume (3) of CO2 at 35F. The change in temperature will change the pressure at the head, not the volume. Volume, pressure, and temperature. Carbing at a higher temperature means you need more pressure to achieve the SAME volume. The same amount of CO2 is be absorbed at either temperature.
I have no room to bring the temp down to serving standards. So I force carbonate at garage temps. Is that a wrong way to do it. May not be ideal but need to get the job done. Been told my beer was under carbonated by someone who would know. This after I force carb at 58 degrees and THEN put in into the kegerator for a week at 37 degrees and 7lbs for 2 weeks. Thoughts?
The temperature of the liquid impacts it's ability to retain the gas in solution. Hence the ability to carbonate to the 3 CO2 volumes using 16psi at 37F, where it takes 30psi to reach the same level at 58F.
The handy-dandy slow force carbonation chart featuring pressure vs. temperature (in degress F)... This is the same chart used to do the 2 week 'set and forget' method of carbonating.
As for MalFet's comment, I don't think so... If you need to push more psi into the keg to obtain the same CO2 volumes level at different temperatures, you will use different amounts of CO2 from the tank.
Chances are, you'll need to pull the pressure relief a few times on the keg once it's at temperature (24-48 hours after putting in the 37F environment). Use a keg pressure tester to see where it's at BEFORE you connect up the gas feed.
This is easy to test if anyone is still skeptical. Carb at one pressure, hook up a pressure gauge and then watch it change as you drop or raise the pressure.
There's really no problem carbonating beers at warm temperatures, though in my only anecdotal experience it can sometimes take longer. If you're trying to carb something really warm (mid70s), you can run the risk of moving past your regulators range, too. But, otherwise, 'salgood!
