So, I've just filled my first two kegs with homebrew and hooked them up to CO2 in the new chest freezer conversion. Got about 7-10 days to wait on carbonation, and, honestly I want my beers to age a little more before drinking. The question I have is, I have looked up serving line length equations which tell me I need ~4 feet of 3/16 ID thickwall tubing to reduce my pressure enough to serve foam free. My pressure is set ~12PSI and my temp is ~38F. I'm shooting for 2.7 volumes of CO2. This line length seems a little low from what I've read on this board about line lengths in other folks kegerators. What are ya'll doing?
