Update: Bottled one as a test last night. Ginger Ale was roughly room temperature and beyond shaking the canister I didn't allow much time for the Co2 to absorb. As expected the bottle was so lightly carbonated this morning it was hardly noticeable.
I just applied Co2 to very cold ginger ale and I have been shaking every few minutes. I'm going to allow the Co2 a few hours and some more shaking to absorb. I am also going to use some tubing so that I can try to prevent losing so much carbonation when dispensing from the canister. I had so much foam on the first test due to it spraying with a lot of force into the bottom of the bottle.
Wish me luck.
