I've got an old 2 1/2 gallon keg I don't use so I thought I'd make some caffeinated root beer to keep on tap.
I bought some Zatarain's extract and some pure caffeine capsules (200mg) to give it a shot. Luckily I decided to test dissolving the contents of the caffeine capsules in water prior to dumping them into the keg with the syrup. I can't get the caffeine to dissolve. It just makes the water cloudy, then eventually settles to the bottom of the glass.
My calculations say that for 2 1/2 gallons I should add 8 capsules to nearly match the caffeination levels of a normal commercial cola. The way the capsules acted in water I would just end up with a bunch of caffeine laying on the bottom of my keg and a bad news caffeine overdose waiting to happen.
Has anyone figured out a way to add caffeine to a homemade soda and keg it?
