carbonating root beer

[jungdahl]

I get my 3 gal cornet keg, pressure gauges, co2 and lines next week.
I plan on making my first batch using Sprechers syrup/extract. The taste is close to the old midwestern root beer I grew up with. Did n Suds and A&w before the recipes were changed.
Question I have.
What pressure do I carbonate at and for how long and what to serve at?

These videos may be helpful. Two different methods for carbonating soda. Your serving line length may also affect what pressure you can serve at so maybe start with a pressure of 15 or 20 psi and then increase until you get the carbonation you like. It will take a few days for a 3 gallon keg to fully carbonate.

I would do the same thing I do with beer - 12 psi at 38-39 degrees and let it sit for a week and adjust as needed. I also use a standard 3/16" beer line with about 10-12 feet of line at 12 psi. You probably don't want to over carbonate root beer.
