Make your favorite drinks sparkle at the touch of a button! For the first time ever, you can carbonate any liquid and infuse drinks with real ingredients directly in the bottle, without a CO2 tank. Whether you’re infusing fruits, sparkling water or alcoholic products, each Spärkel Carbonator perfectly customizes one bottle, ensuring a perfect (and delicious!) experience every time without dilution. No clunky CO2 tanks, just bubbles. Say goodbye to exchange programs and returning CO2 tanks. Spärkel carbonators are a special granulation of citric acid and sodium bicarbonate. Each carbonator is placed in a sealed chamber within the appliance and generates CO2 gas that travels to the bottle.
