Carbonated Coffee

For my first carbonation attempt I tried coffee. I brewed one serving (about a pint) via the usual method then added another half cup of water, chilled it, and then force carbonated it at ~27psi until it seemed to stop taking gas. After letting it sit in the fridge for 20 or 30 minutes I impatiently tried it, but the initial opening produced a LOT of foam. After dealing with some bottle overflow I tried a couple ounces, and it was both what I expected and something bizarre. It was cold (like iced) coffee, but with an extra bitter flavor likely from the carbonic acid formed during the carbonation.

I’ll drink it tomorrow, likely with breakfast or lunch. It should be colder and less foamy and maybe even enjoyable. After that I’ll probably try making some soda, likely ginger or cream. I feel like I’m getting dangerously close to molecular gastronomy. If I post about acquiring a Dewar and some LN2 please warn me.

Carbonating / Kegging Supplies

While planning a New Year’s Eve party I realized that it’d be particularly handy to have supplies for dispensing kegged beer with CO2. Well, after a run to Cap n’ Cork I now have everything needed: a CO2 tank, regulator, thick-wall PVC line, a corney keg, picnic tap, keg rebuild kit, and ball lock fittings. I also picked up cherry and cream soda mixes and a special cap that allows one to carbonate things in plain plastic bottles. Now I can make carbonated water, juice, milk, or anything else whenever I want. Hmm. I think I could even try carbonating fruit…
