Soda makers have been around for quite a while, but mostly in the guise of soda siphons that were meant for dispensing soda water into a cocktail. Now, home soda makers are used for making sparkling water, flavored sodas, and more to cut down on packaging waste and replace store-bought products. After all, when you make your soda yourself, you know exactly what you’re consuming.
Home soda makers are also great for making original and unusual flavors using fruit juices as flavorings. Many soda... makers are designed for carbonating water and adding flavor after, but some can be used to carbonate any liquid you like, including fruit juices, cocktails, and wine.
Soda makers require small (usually 8-gram) CO2 cartridges or small cylinders (14 1/2 ounces, usually described as 60 liters) of CO2 to carbonate the liquid. While brand-name and proprietary cartridges can be expensive, there are many alternatives on the market. Bought in bulk, the 8-gram cartridges can be less than 35 cents each. There are also ways to adapt these machines to use re-fillable tanks intended for beer brewing. With that in mind, these are the best picks for most people.
One of the first brands to make soda makers popular, it’s no surprise that SodaStream tops our list. This model comes with a 4-ounce starter cylinder of CO2 for carbonating up to 6 liters of soda, depending on how fizzy you like your water. That starter cylinder can be replaced with a 60-liter cylinder that will make up to 60 liters of fizzy water, or it might make much less if you like your water with extra bubbles. The kit comes with a coupon for a free 60-liter cylinder as well. Because of... its popularity, these CO2 cylinders can be found at many retail locations as well as online. A 60-liter cylinder costs about $30 to purchase a full tank, and about $15 to exchange an empty tank for a full one.
You can choose one of three levels of fizziness, and the proprietary snap-lock bottle snaps in and out of the machine for secure carbonating. The bottle has a special fizz-preserving bottle cap for storing the carbonated drinks as well. A two-pack of extra one-liter bottles is will cost about $16. The company also has more than 60 flavorings available for purchase that enable you to create your own sodas by adding them to the water after it’s carbonated.
Beautiful, functional, and efficient, the Crystal starter kit from SodaStream includes a reusable glass carafe rather than plastic and makes the process faster and easier with quick bottle flask insertion, so there’s less fiddling to get the bottle in place.
