First-Timer: My water is not (fully) carbonating!
I am working on carbonating my own soda. I got a 5 gallon corny keg, a 5lb CO2 tank, and everything I need to connect it. The one suboptimal thing that restricts me is my fridge space. I don’t have enough to store my keg in it while carbonating and I don’t have a spare outlet to buy a chest freezer. It is simply not an option. The best thing I can do is keep it in my basement, which is colder than my house and should be enough.
I connected everything, ensured there were no leaks, and set my regulator to 45 psi. I then left it for a week (168 hours). When I went to check on it and try the water (I turn off my regulator before attaching my dispensing hose) the water was a little bubbly, but it barely tasted any different. It was lightly carbonated, and did not taste good.
In that time I bought a corny keg carbonation lid (with the cold stone and tube that goes to the bottom), which advertises carbonation in 1-2 days, which should really speed up my testing process. I also got a Zigbee temperature ready so I could track the average temperature in my basement. In that past week (including up to now) I found my basement temperature was always between 59.5° and 64° Fahrenheit. After re-crunching the numbers I found out I was under-pressurizing it, which is why it wasn’t very bubbly. I set my pressure to 60 psi. Lastly, I know this will barely do anything, but I set my keg in a 5 gallon bucket, and filled it with water and ice. Over the next few days I would go down to refill the ice and shake the keg. After turning back on the regulator (and shaking the keg) I hear a satisfying bubbling noise inside of the keg, which means I know this is working.
Almost 24 hours later I went to check on it again and it barely tasted different. Maybe even not different at all, I’m not sure. I turned the wheel on my CO2 tank and realized it was not locked to all the way open. I didn’t think it was any different as if it was moderately open the gas is at a high enough pressure (and the CO2 tube so small) that it barely mattered. Anyway, I ensured it was all the way open and left it again.
I went down 24 hours after that to try again. The water wasn’t any more carbonated before, and tastes pretty bad! When dispensing it there are some bubbles, and it foams, but it is just a layer of flim that dissipates quickly on the top layer. Nothing like the level a real soda machine dispenses.
It is now 24 hours after that. 72 hours carbonating with the carbonation lid. This time I looked everywhere online and tried to do the “optimal dispensing setup.” I turned off my regulator and turned it to 0 psi. I vented all of the pressure in my keg, then turned on my regulator and raised it to 10 psi. I then grabbed an ice-cold soda bottle from my freezer and dispensed my soda in it - and it tasted the same as before! I have no idea why my water is not carbonating. I know my basement isn’t the best temperature to do this at, but I should still be getting something, right? What am I doing wrong?
