My name is GG and I am a Seltzer Addict. I got my husband hooked, too. We each have a 1 or 2 bottle a day habit. I started feeling schmucky about the environmental impact of all that bottled soda (especially when I see the giant plastic bags full of bottles waiting to go to recycling). And it's a lot of schlepping of bottles from the grocery store. So I started looking into making our own.
Some research turned up that your basic soda siphon doesn't make very fizzy seltzer, and that those little CO2 cartridges get expensive and are a PITA. Then I found a thread on Chowhound about the Soda Club soda maker. Sounded like just the ticket. I ordered one. It arrived yesterday.
It makes incredible seltzer. I'm sure using our sweet Vermont well water helps, but I can control the amount of fizz – I can make it strong enough to burn my nose and make my eyes water (spectacular!). And each big CO2 canister will carbonate up to 110 liters of water. And it comes with reusable plastic bottles. Excellent.
Check it out:
– Soda Club website– Pictures and review on Cooking for EngineersThe set-up also comes with a sampler of the soda flavorings available from the company. I threw them away – even the non-diet ones have Splenda in them.
But I'm looking forward to experimenting with making my own soda (I had a lemon verbena soda at Hugo's in Portland that has haunted me for nigh on 3 years).
I have a similar unit that we bought some five years ago. They use mini canisters. The problem with these things is getting the canisters refilled locally. It has to do with the fact that they use a non-standard fitting.
If you are lucky, you can establish a rapport with your local fire extinguisher supply or paintball gun sports store and they can refill the CO2, if they can get the mating fitting for their gas supply to attach to the canister.
I gave up on my machine a few years ago when my local guy went out of biz who could do the refills and just had my local Nestle Waters supplier deliver me
six cases of 16oz plastic bottles of Poland Spring Sparkling every month. Its a lot more convenient than having to schlep home water bottles.
If you're really serious about soda -- you get yourself a standard 10 or 20 pound tank that you can exchange with a regular CO2 supply company periodically and hook up a restaurant-style gun. The guns and associated hardware for a basic soda setup can usually be found on eBay for less than 200 bucks.
My primary interest was in getting away from massive consumption of plastic bottles. The set-up I bought came with 3 CO2 canisters, each capable of carbonating up to 110 liters of water. When you need more CO2 you ship back the empties and order full ones (@$20/ea + shipping). It does require a little advance planning, but I'm compulsive enough that I don't see its being a problem.
