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.
