You use your Fizz Kit for sparkling water. Maybe occasionally for a mocktail. But have you ever tried making your own sparkling tea? Homemade Sparkling Tea is probably the best-kept secret in the home kitchen. Once you've had an ice-cold, fizzy hibiscus tea on a summer afternoon, there's no going back.
Here, you'll learn everything you need to know: which teas work best, how to prepare them, and why your flav& Fizz Kit is already the perfect tool for the job.
Why carbonate tea?
The sparkling tea trend is in full swing. Ready-made sparkling teas in cans have taken over the beverage market - but most are packed with sugar and artificial flavors. When you carbonate your own tea, you stay in full control: the tea you want, the fizz you love, and no unnecessary additives.
And it's surprisingly easy. The Fizz Kit doesn't care whether you fill the bottle with regular water or cold-brewed green tea - it simply adds CO₂. The result is a clean, lightly sparkling drink that tastes genuinely amazing - without much effort.
The golden rule: carbonate cold, never warm!
Before we dive into the different tea varieties, there's one golden rule for perfect sparkling tea: Your tea must be completely cold before carbonation.
Warm liquids hold carbonation much more poorly. You'll get less fizz and more foam. Brew your tea, let it cool to room temperature, then chill it in the fridge for at least one hour (preferably overnight). Cold tea + Fizz Kit = perfect bubbles every time.
Also remember:
- no milk
- no cream
- no thick syrups before carbonation.
Add those afterward. The Fizz Kit is designed for water-based liquids - carbonate first, then customize to taste.
The best teas to carbonate with the Fizz Kit
With the best teas for your DIY sparkling tea, you can turn ordinary tap water into a truly refreshing experience. If you're looking for an alternative to overly sugary sodas, carbonating your own tea is a fantastic option. The sparkling result is a treat for the senses - not only delicious, but beautiful to look at too. Here's how to create the perfect sparkling tea with your Fizz Kit.
1. Cold Brew Green Tea

Green tea is the perfect starting point if it's your first time carbonating tea. Cold brewed (simply steep loose leaves or tea bags in cold water in the fridge for 6–12 hours), it becomes light, gently grassy, and naturally almost sweet - without any sugar. Once carbonated, the result may surprise you.
Preparation: Add 2–3 green tea bags to 1 L of cold water. Chill for 8 hours. Remove the tea bags, pour into the Fizz Bottle, and carbonate with the Fizz Kit. Serve with ice, a slice of cucumber, or a splash of lime.
Why it works: The low tannin content helps the tea maintain a smooth and clean texture during carbonation, significantly reducing bitterness.
2. Hibiscus Tea (Agua de Jamaica)

If there's one tea made for carbonation, it's hibiscus tea. Its deep ruby color looks stunning in a glass, the tart-sweet flavor shines with bubbles, and it pairs perfectly with a squeeze of lemon or a few fresh mint leaves.
Preparation: Brew dried hibiscus flowers in hot water (1 tbsp per 500 ml) and lightly sweeten with honey or agave syrup if desired. Let it cool completely and refrigerate. Pour into the Fizz Bottle and carbonate. If the flavor is too intense, simply dilute with a little cold water.
Why it works: Hibiscus' natural acidity complements carbonation much like citrus fruits do. The bubbles enhance the perception of flavor.
3. Cold Brew Black Tea (Earl Grey)
Imagine delicious sparkling iced tea - but properly done. Cold-brewed black tea (especially Earl Grey) has a smoother, less bitter flavor than hot-brewed tea. Carbonated, it becomes an incredibly refreshing sparkling tea perfect for anyone skipping alcohol.
Preparation: Steep 2 Earl Grey tea bags in 1 L of cold water in the fridge for 10–12 hours. Remove the tea bags, carbonate, and serve with an orange slice and ice cubes. A splash of vanilla syrup turns it into something truly special.
Why it works: The bergamot aroma in Earl Grey creates a sensationally refreshing combination that feels bright, citrusy, and summery.
4. Sparkling Matcha Water
This recipe is something truly special! Instead of carbonating traditional tea, you're making delicious matcha-infused sparkling water. It's one of the hottest trends in trendy cafés across Berlin and Vienna - and you can make it at home in just minutes.
Preparation: Mix ½ tsp ceremonial-grade matcha with 50 ml cold water until smooth. Pour into the Fizz Bottle, top up with cold water to 1 L, and carbonate. The result: delicate green sparkling water with a subtle umami kick.
Why it works: Matcha has a naturally sweet flavor and rich umami notes, making it a fantastic alternative to regular water - especially when you need extra energy. And the color alone makes it worthwhile.
5. Chamomile & Honey

A gentler option - but one that shouldn't be underestimated. The delicate floral sweetness of cold-brewed chamomile becomes wonderfully elevated with carbonation. Add a small spoonful of honey before chilling (stir until dissolved), and you'll have a lightly sweet, fragrant sparkling tea that works just as well for brunch as it does in the evening.
Preparation: Steep 3 chamomile tea bags overnight in 1 L cold water. Remove the tea bags, stir in 1 tsp honey until dissolved. Carbonate with the Fizz Kit and serve with a slice of lemon.
Why it works: Chamomile's light character pairs beautifully with bubbles, creating a flavor experience that truly comes alive through carbonation.
Pro tips for the best carbonation results
To make sure your sparkling tea experiment succeeds on the first try and the carbonation stays perfect in the glass, keep these simple tips in mind. These small adjustments will help you get the freshest possible result from your homemade sparkling tea:
- Always start ice cold: Room temperature is the minimum, but straight from the fridge is much better for long-lasting bubbles.
- Strain well: Loose particles or sediment can affect carbonation. Always pour through a fine sieve before filling the Fizz Bottle.
- Don't overfill: Leave the same headspace you would for regular water - the Fizz Bottle has a fill line for a reason.
- Taste before sweetening: Cold brew teas often taste naturally sweeter and smoother than hot-brewed teas. Carbonate first, taste, then adjust.
- Use short bursts when carbonating: Flavored liquids can react more intensely than plain water. For better control, press the carbonator two or three short times instead of one long press.

Frequently Asked Questions About Sparkling Tea
Can you carbonate any tea with the Fizz Kit?
Yes, most cold-brewed and properly strained teas work perfectly. The key is making sure the liquid is completely cold and free from milk, cream, or thick syrups before carbonation. Light, water-based teas such as green tea, black tea, herbal tea, and hibiscus are ideal for carbonation.
Does carbonation change the flavor of tea?
Yes - and in a good way! Carbonation enhances the delicate flavor notes of tea, makes natural fruit acids (like hibiscus) feel brighter, and creates a refreshing mouthfeel. Teas that seem too subtle when cold brewed often become far more vibrant with a little fizz, almost resembling sparkling wine - just without the sugar.
Can I add fruit juice to sparkling tea?
Absolutely - but it's best added after carbonation directly in the glass! Once you've mastered carbonated tea, you can enhance it beautifully with fresh lemon, lime, or pomegranate juice. Carbonating juice directly in the bottle can work in tiny amounts, but highly acidic or sugary juices may cause carbonation to fade faster or make the liquid foam excessively inside the machine.
How long does homemade sparkling tea stay fizzy?
Sparkling tea is best enjoyed within 24 hours. If you seal the Fizz Bottle tightly and store it in the fridge, the carbonation will hold up well. But like all fresh sparkling drinks, it tastes most lively when freshly carbonated.
Is sparkling tea healthy?
If you make your sparkling tea at home using pure cold-brewed tea without added sugar, it's an extremely healthy choice. You benefit from all the natural antioxidants and vitamins in tea leaves while avoiding artificial flavors, preservatives, and sweeteners completely. The carbonation simply adds refreshing bubbles - with zero calories.
