Quick answer
To make a Diet Pepsi Caffeine Free soda at home, carbonate cold water in your SodaStream machine, then mix in the SodaStream Diet Pepsi Caffeine Free drink mix. Stir gently and enjoy a crisp, caffeine-free cola.
Why choose the caffeine-free version?
The SodaStream Diet Pepsi Caffeine Free drink mix delivers the same authentic Diet Pepsi taste without the caffeine. This makes it a great option for evening enjoyment or for anyone reducing their caffeine intake. The four-pack provides 16 servings, offering good value compared to store-bought cans.
What you need for the perfect fizz
Success starts with cold, filtered water. Cold water absorbs CO₂ better, giving you a more satisfying fizz. Fill your SodaStream bottle to the fill line, and make sure it's chilled before carbonating.
Steps to make Diet Pepsi Caffeine Free at home
- Chill your water: Fill your SodaStream carbonating bottle with cold filtered water. For best results, refrigerate the water for at least 30 minutes before carbonating. Cold water holds carbonation much better than room-temperature water. Using warm water will result in flat soda. Always start with cold water.
- Carbonate the water: Attach the bottle to your SodaStream machine and press the carbonation button in short bursts. Listen for 3-5 hisses or until you hear the CO₂ release sound. Over-carbonating can cause excessive foam when you add the mix. Stop carbonating as soon as you hear the release sound. Too many bursts will make the soda overly fizzy and cause overflow.
- Add the drink mix: Remove the bottle from the machine and add the Diet Pepsi Caffeine Free drink mix to the carbonated water. Use one serving (the cap of the mix bottle or the pre-measured packet) per 500ml of water. Stir gently with a long spoon to avoid losing carbonation. Pour the mix slowly and stir gently to keep the fizz intact. Vigorous stirring will cause the soda to go flat.
- Serve and enjoy: Pour the mixed soda over ice if desired, and enjoy immediately. For the best taste, drink within 10 minutes of mixing. Leftover soda can be stored in the refrigerator in a sealed container, but carbonation will diminish over time. This soda is best fresh. If you must store it, keep it sealed and cold, but expect some fizz loss.
