Good point! I've updated the calculator also to include the absorption, which is almost always the dominant effect if the system is left to reach equilibrium. In MagicMatt's case he'd need about 12 feet of 1" line, and 3 feet of line would allow up to 3 pints of suck back!

Are you carbing cold? If so, do you notice any difference in how long it takes to get the dry hop flavors? Do you do anything to purge oxygen from the hop bags before you put them in? And when you want to remove the dry hops, presumably you disconnect the gas, de-pressurize the keg, open the...

Time for some math: Assuming that you're cold-crashing from around 70F to just above freezing, the volume of the gas in the head-space will shrink by about 7%, and of the beer by about 0.2%. As a specific example, a 6G fermentor with 5G of beer will suck back ([6-5] x 0.07 + 5 x 0.002) =...

If you went BIAB you'd only need a bag to be all set to do 10G batches in the 20G kettles right now.

The other cold-crashing bugbear is sucking air back into the fermentor as it cools and the associated risks of oxygenation, especially for hoppy beers. Some people even attach a balloon full of CO2 to the air lock to avoid this. As a physicist, my head just assploded. Things drop out of...

For bonus wedding symbolism, how about giving everyone a pair of 12oz bottles that are both fine alone but also mix well ... something like a black and tan. Then you can even do labels that associate one with each of the brides, and they become a keepsake beyond the beer.

Once more for luck.

Did the daily drawings stop after Friday?

I made a brown porter.

If at first you don't succeed ...

Final note: a sanke coupler adapted for either ball- or pin-lock disconnects (depending on which you go with) is a really nice addition, letting you run a commercial keg if and when your pipeline runs dry - much cheaper than 6-packs!

Check out the chest freezer specs here: https://www.homebrewtalk.com/showthread.php?t=377518 Decide on ball- or pin-lock kegs and stick with one type. Ball-lock are narrower and taller (so fit better in a chest freezer with a collar) and have pressure relief valves, but they're more expensive...

Cracked the last bottle of my February 2015 batch after dinner last night and it had aged beautifully (the rest were gone by New Year). Wonderful balance of dark stone fruits, walnut, and chocolate, lots of warmth but no heat, fantastic with a slice of pecan pie.

Love me some kegconnection.

Where in NorCal are you?

Nope ... let it ride and hope for the best (90% chance everything is just fine).

You're right - the volume of beer is irrelevant. The only information the calculator should need is the desired carbonation level and the temperature. Which calculator are you using? Are you sure you're not confusing the volumes of CO2 with volume of beer?

I'm missing something ... how were you previously pushing the Star San *without* tubing on the "out" side?
