Brewing Sparkling Tea: From Tea Leaves to Premium Ready-to-Drink Beverage
Sparkling tea has become one of the fastest-growing categories in the premium beverage market. Combining the delicate aroma of high-quality tea with refreshing carbonation, sparkling tea offers a sophisticated alternative to beer, soft drinks, and alcoholic beverages. Whether it is a non-alcoholic sparkling green tea, kombucha-inspired sparkling tea, or botanical tea beverage, manufacturers require carefully controlled brewing, filtration, carbonation, filling, and pasteurization processes to ensure excellent flavor and shelf stability.
As a professional manufacturer of beverage processing equipment, TIANTAI provides complete turnkey solutions for sparkling tea production, from raw material handling to canning or bottling.
What Is Sparkling Tea?
Sparkling tea is a carbonated beverage produced by extracting tea leaves, blending with sugar or natural sweeteners (optional), adjusting acidity, chilling, carbonating with food-grade CO₂, and packaging under hygienic conditions.
Popular products include:
- Sparkling Green Tea
- Sparkling Black Tea
- Sparkling Oolong Tea
- Sparkling White Tea
- Herbal Sparkling Tea
- Fruit-Flavored Sparkling Tea
- Botanical Sparkling Tea
- Premium Non-Alcoholic Sparkling Tea
Unlike kombucha, traditional sparkling tea usually contains no active fermentation and has virtually no alcohol, making it easier to produce with consistent quality.
Typical Sparkling Tea Production Process
Raw Water Treatment ⇒ Tea Brewing ⇒ Tea Filtration ⇒ Cooling ⇒ Sugar Syrup Preparation (Optional) ⇒ Blending Tank ⇒ Fine Filtration ⇒ Deaeration (Optional) ⇒ Carbonation
⇒ Buffer Tank ⇒ Can Filling & Seaming ⇒ Tunnel Pasteurization (Optional)⇒ Cooling ⇒ Packaging
Step 1 – Water Treatment
Water quality directly affects tea flavor.
Typical treatment includes:
- Sand filter
- Activated carbon filter
- Water softener (optional)
- Reverse Osmosis (RO) system
- UV sterilizer
Recommended conductivity after RO: 10–50 μS/cm
Step 2 – Tea Extraction (Brewing)
Tea extraction is one of the most critical steps because excessive temperature or prolonged extraction can increase bitterness and astringency.
Green Tea
- Water temperature: 75–85°C
- Brewing time: 5～10分
Black Tea
- Water temperature: 90–95°C
- Brewing time: 8–15 minutes
Oolong Tea
- Water temperature: 85–90°C
- Brewing time: 6–12 minutes
White Tea
- Water temperature: 75–80°C
- Brewing time: 6–10 minutes
Agitation during extraction helps improve extraction efficiency without damaging tea leaves.
After extraction, spent tea leaves are removed using filtration equipment.
Step 3 – Tea Filtration
Proper filtration ensures excellent appearance and prevents sediment.
Typical filtration stages include:
- Coarse filter
- Bag filter
- プレートフィルター
- Cartridge filter (1–5 μm)
For premium sparkling tea products requiring crystal-clear appearance, membrane filtration can also be used.
Step 4 – Cooling
Tea should be cooled rapidly after extraction. Recommended temperature: 2–4°C
Rapid cooling preserves aroma while preparing the product for carbonation. A plate heat exchanger combined with chilled water or glycol cooling is commonly used.
Step 5 – Syrup Preparation & Blending
Depending on the recipe, ingredients may include:
- 砂糖シロップ
- Natural fruit juice
- 植物エキス
- Natural flavors
- クエン酸
- Vitamin C (ascorbic acid)
- Natural sweeteners
Blending is performed in a sanitary mixing tank with gentle agitation.
Step 6 – Fine Filtration
Before carbonation, final polishing filtration removes remaining particles.
Typical filtration:
- 1 μm cartridge filter
- 0.45 μm filter (optional)
This greatly improves product clarity and shelf stability.
Step 7 – Carbonation
Carbonation gives sparkling tea its refreshing mouthfeel. The beverage should be cooled before carbonation.
Recommended product temperature: 0–4°C
Typical carbonation pressure: 2.0–4.0 bar
Typical CO₂ level: 2.5–4.5 volumes
Higher carbonation requires lower beverage temperature for improved CO₂ absorption. A dedicated carbonation unit ensures stable dissolved CO₂ and consistent product quality.
Step 8 – Can Filling
For sparkling beverages, counter-pressure filling is essential to minimize CO₂ loss.
Typical packaging:
- 250 ml Slim Can
- 330 ml Standard Can
- 355 ml Can
- 500 ml Can
A complete canning line typically includes:
- Empty Can Depalletizer
- Can Rinser
- Counter-Pressure Can Filler
- Can Seamer
- Date Coding Machine
- Tunnel Pasteurizer (optional)
- Can Dryer
- Labeling Machine (optional)
- Carton Packing Machine
- パレタイザー
Counter-pressure filling minimizes foaming while maintaining carbonation.
Step 9 – Pasteurization
Whether pasteurization is required depends on the beverage formulation.
Products requiring pasteurization
- Sugar-containing sparkling tea
- Fruit tea
- Juice tea
- Botanical tea beverages
Typical tunnel pasteurization:
- Product temperature: 60–65°C
- Holding time: 10–20 minutes
- Typical pasteurization value: 10–20 PU
After pasteurization, cans are gradually cooled to ambient temperature.
Products that may not require pasteurization
Some premium sparkling teas produced under aseptic conditions with preservatives or sterile filtration may omit thermal pasteurization. The appropriate preservation method depends on the desired shelf life, distribution conditions, and local food regulations.
Step 10 – Packaging
Finished cans are packed into:
- 4-pack
- 6-pack
- 12-pack
- 24-pack cartons
Automatic carton packers and palletizers improve production efficiency while reducing labor costs.
