Here’s an excellent write-up on making a beverage carbonation system from Jeffrey Morgenthaler, bar manager of Clyde Common and drinks blogger extraordinaire. Jeffrey has published some delicious carbonated bottle cocktail recipes on his site, but gets a lot of questions about the actual act of making them fizz:
… about once a week I get an email from someone asking me how to do one of several things:
- Carbonate cocktails in a way that won’t result in exploding equipment.
- Carbonate ginger beer or other mixers without resorting to yeast.
- Carbonate cocktails for draft delivery.
So here are the two systems that can do all of those things. Here we go.
… I was able to put together a kit that takes less than five minutes to assemble, cost me around a hundred and fifty bucks to build, and costs next to nothing to operate.
I have a SodaStream at home, but it uses expensive, proprietary refill cartridges, so I’m tempted to build a system following Jeffrey’s directions. He outlines assembling a CO2 tank, regulator, carbonator cap, and fittings to then carbonate beverages in standard plastic two liter bottles. Total cost is around $160.
