i'm alittle confused now. i found a syrup mix that mixes with water to make 5 gallons. they said it needs to be carbonated with co2. now, i have the 5 gallon corny kegs and a co2 set up. if i mix a batch up, how does just the co2 carbonate it? i sell lemonades and we pump the syrup mixture out of the kegs with the co2 and it isn't carbonated? anyone help on this? thanks, kenny
co2 will dissolve into water all by itself, depending on time, temperature and pressure. if you were to mix up your rootbeer syrup with water in a keg, then place the keg someplace cold around 36-40F (like a walk-in cooler or large refrigerator, the keg must remain upright..) with the co2 gas connected at 40-50psi, in 4-5 days the contents of the keg will become carbonated. the process can be sped up by shaking the keg, which some people do, but shaking 5 gallons of liquid isn't easy.......... you dispense using the same type of tapping equipment that the homebrew beer guys use, except that you need about 20' of 'beer line' instead of the usual 5-10' used for beer, to prevent excessive foaming (the longer tubing equalizes the dispensing pressure so the co2 doesn't come out of suspension, causing foam)
i've made plain seltzer, coca cola, pepsi, various brands of root beer, all the same way. commercial soda syrups usually state the mixing ratio on the container, 5-1 for most, 5.5-1 for diet syrups.
