Turn flat water into sparkling water in the palm of your hand

SodaStream has been the biggest name in home carbonation for generations, but a revolutionary new water bottle has been introduced. CES 2025 he hopes you will drop (or increase) yours countertop soda machine for a more portable way to get your fizz.

The Roam SodaTop is like a portable SodaStream. The head is where the magic happens. A tight seal and a small CO2 cartridge turn stagnant water into something more exciting. You can screw the top on a water bottle Roam is sold, or on a compatible water bottle (like a HydroFlask).

Roam plans to start selling the SodaTop directly from their website in the first quarter of 2025, for $50. CO2 cartridges are expected to cost about 70 cents each.

Manual carbonation on the go

The Roam SodaTop process is simple. Insert a CO2 cartridge into the special lid of the SodaTop, release that carbon dioxide into the bottle, leave the excess gas inside and drink. Each cartridge is good for only one liter of water.

Roam says its stainless steel water bottles are designed to keep drinks cold for 24 hours. If you already have a SodaStream, Roam also has an adapter cap, which will sell for $13, that allows you to carbonate your drinks from your countertop machine.

The taste is in the crisp air

The only thing you should carbonate in the bottle is the water, but that doesn’t mean you can’t add flavor. Flavored syrups or other drink mixes can be added after the CO2 if you want something that tastes like, well, something. But Roam also develops its own ways to add variety.

CEO Sunjay Guleria said the company is working on flavored CO2 cartridges, which contain the essence of a flavor and allow you to make your own calorie-free sparkling water with just plain water and the cartridge. Imagine the flavors of ginger, lemon, yuzu, grapefruit or white peach – natural sparkling water or flavored sparkling water fresh in your bottle. It’s refreshing.
