This post is a follow up to "Foamy Beer? No fear!" that I put up part way through December.
For some follow up, I had some issues with the beer lines in my kegerator. At the very first installment, I didn't realize that they needed to be any certain length. They were roughly 3 feet long, and they poured a very foamy beer. Then with some research at Homebrewtalk, I found (but I misinterpreted) that my lines should be 5 feet long. However, I was still pouring foamy beer. After more research, I found that for different beers, at different levels of carbonation, really need different lengths of line. Some might pour foamy, some might pour too flat.
This can be cured with the worst case scenario lines, which would end up being about 10 feet. I wasn't ready to throw out my old lines, and I wasn't ready to run 40 feet of tubing inside my kegerator. In comes the post "cure for your short hose troubles" (Link here).
These handy plastic mixing sticks, used for mixing epoxy, fits perfectly in the dip tube on the liquid side of your keg. The intent is that it creates the resistance in your line you need to pressurize your keg to the appropriate carbonation level, and still pour a good beer.
And here's proof. At this point in my pour, I would've had an entire pint full of foam. But by the time the pint is full, I've got a nice 3/4" head on the beer. Now it's not perfect across the board, some beers pour a little foamier than others. But that's quite alright. My system pours a hundred times better now, and I can keep all the kegs carbonated at the correct level.
In my opinion you shouldn't operate a homebrew kegerator without one of these handy dandy little mixers. So if you have one, go back to my December post about them, and order a few of McMaster Carr. They're so inexpensive, especially compared to how much you've spent on the rest of your system, there's no reason not to.
