soda not carbonating, what am I doing wrong
I put together an extract and water mix and placed it in my soda keg about 2 weeks ago.
I wanted to get the soda force carbonated quickly for my kids. I have two regulators on my co2 tank, one for soda and the other for my beer.
I put my soda under higher pressure to speed up the force carbonating. I have had it around 40-50 psi for the entire two weeks. I am just beginning to see some tiny bubbles in the soda, but it is still very flat.
What am I doing wrong or missing???????

Are you cooling the soda? Try getting it down to 30ish and then hit it with gas. Also shaking it helps.

Keg is in keezer at 36 degrees. I can shake, but it still should carbonate on its own, right?

It should carbonate if just left alone yes. But will take much longer. One thing to remember is beer starts out with dissolved CO2.

Call me crazy but...what will allow the water plus extract to self carbonate? There has to either be a fermentation process and contained carbonation or forced carbonation. Or am I reading this thread incorrectly?

He is talking about force carbing the soda.

Will a small leak cause this issue??? I turned the main valve off at the tank and when I checked back the next day, the pressure dropped to around 5 psi from 25 psi. I am wondering if the soda is not absorbing the CO2 because it is just running out some small leak.

I believe that as the liquid absorbs the CO2, the pressure will drop. Thats why a constant pressure is required to carb effectively.

I've had this problem for over a year since I switched from Yeast carbonation to C02 and kegging carbonation. I have gotten very flat sodas with microbubbles on the sides.
Primary setup: 5 Gallon corny keg -> 25 feet of hose ->Blichmann beer gun -> bottles
I was trying to mix soda concentrates with water and then add the C02 (30 PSI for 3-7 days) -> failed
I tried mixing concentrate with seltzer water -> failed

I just purchased a carbonation stone-lid to try and gas my water and concentrate mixture in the keg. Has anyone has success or experience doing it this way?
