Also keep in mind that you will use a different pressure setting based on temperature and warm beer absorbs co2 slower so it may take longer than normal.

I don't think this is correct. Given adherence to the chart for the exact same volumes of CO2, physics says the warmer beer should reach equilibrium faster than the cold beer.

You're exactly right, I was relying on memory and got it backwards...my bad.

Yup. Diffusion is faster when the system is warmer.

True but if you are boost carbing then cold is better

What's boost carbing?

Hi pressure low temp for a short period of time.

It is true that diffusion is faster given the same pressure and a higher temp. But also the required pressure for a given volume of CO2 is lower for lower temp. So if you doing it properly you can boost carb to 80% of the deaired vols overnight. At a low temp and high pressure.

The system can only handle a certain max pressure. That max press sure packs more of a punch at low temp

Hey Guys,

I have a few quick questions that someone can hopefully answer (and I assume have already been answered here). Sorry for the lack of foresight in planning on my part but I'd like to get my first keg up and running by Saturday if at all possible. Obviously I'd need to do the burst carb method at this point. So here goes:

1) Right now I'm using a full size fridge without a temp controller. I actually just got one in the mail today, but I'm not sure if I'll have time to get it up and running before I need to start kegging. Should I take the average temperature in my fridge when calculating carbonation rate? For example:

Min Temp: 34F
Max Temp: 43F
Avg Temp: 38.5F

The only issue with this method is that this assumes that it spends equal amounts of time. I guess this temperature could also be considered the "median" temperature. Either way, how should I go about planning my CO2 volumes until I can get it properly regulated?

2) Assuming we go for 38.5F and I want 2.5 volumes of CO2 (for a Cream Ale), I'd set the PSI to approx 3 time the level listed in the chart (12psi x 3 = 36psi) for 24hrs, purge the head space, then set the regulator to 12psi. That gets me to Saturday when I'd like to serve. Would it be ok to serve then at 12psi or do I drop the pressure further to a lower serving pressure, and if so how do I calculate that? Is that based off of keg line lengths? This is all assuming no shaking of the keg. Would I need to do some sort of shaking and adjustments to my original psi calculations?

3) I'll be dispensing from a picnic tap with a super short line length. I assume is close to 3.5', and everything I've read said that I should get a much longer length of line. Is there anyway that I could serve from this? If not I can make a run down to the LHBS and pick up a 10' line.

Thanks for helping out. I'll hopefully start getting this carbed up as soon as possible, so any quick responses would be greatly appreciated. I don't know what I'd do without you fine folks here at HBT!

Cheers!

Im sure someone will give you a proper answer, but this is mine

1. Taste it after your day of quick carbing (36psi)and degassing, you well be able to tell whats right by taste.

2. You should either get a longer line(+) or try 8-10psi to see if that works.

3. Drink up and cheers!
