RTD Cold-Brew Oolong Product Development Checklist
RTD cold-brew oolong development should begin as a controlled product-development project: define the beverage concept, choose an oolong base, build a pilot formula, validate sensory performance, then separately verify stability, food safety, packaging, labelling and market compliance before sale.
Where FEISHUIJI fits in the RTD process
FEISHUIJI can support the tea-base and application-development stage: choosing an oolong direction, preparing sample formulas, comparing cold brew, roasted oolong and fruit oolong routes, and helping the buyer define what should be tested next. The buyer or qualified manufacturing partner must validate finished RTD safety and market compliance.
RTD development checklist
| Stage | Question to answer | Practical output |
|---|---|---|
| Concept | Is the drink plain cold brew, fruit oolong, sparkling oolong, milk tea or tea coffee? | One-page product brief and target consumer. |
| Tea-base selection | Which base gives the intended aroma after chilling and processing? | Shortlist TG-01, TG-04 or BQ-01 for pilot testing. |
| Pilot formula | What are tea, water, sweetener, acid, fruit, milk or carbonation levels? | Gram-based bench formula and sample code. |
| Sensory validation | Does aroma, body, bitterness and color survive the intended holding time? | Panel notes and preferred formula version. |
| Processing route | Will the product be refrigerated, pasteurized, aseptic, hot-fill, carbonated or made fresh? | Manufacturing route decision by qualified plant. |
| Safety and stability | What microbial, pH, water activity, packaging and shelf-life testing is required? | Lab and QA test plan before public sale. |
| Label and market | What ingredients, caffeine, allergens, nutrition, claims and import rules apply? | Reviewed label and destination-market compliance checklist. |
Best FEISHUIJI bases to test first
| RTD concept | Starting base | Why |
|---|---|---|
| Clean cold-brew oolong | TG-01 Light-Aroma Tieguanyin | Fresh floral profile and clean finish. |
| Roasted cold-brew oolong | TG-04 Charcoal-Roasted Tieguanyin | Roast depth, caramel and coffee-adjacent structure. |
| Fruit cold-brew oolong | BQ-01 Baiya Qilan High-Aroma Oolong | Floral-fruity aroma supports peach, pear, citrus and light syrup. |
| Milk or oat RTD concept | TG-02 Rich-Aroma Tieguanyin | Rounded body for dairy or plant-milk testing. |
Bench formula starting points
| Concept | Small pilot formula | What to evaluate |
|---|---|---|
| Plain cold brew | 10 g TG-01 + 500 g cold water, 6-8 hours, filtered. | Aroma clarity, color, bitterness and chilled finish. |
| Roasted cold brew | 10 g TG-04 + 500 g cold water, 6-8 hours, filtered; optional 10 g syrup. | Roast depth, caramel note, coffee drinker acceptance. |
| Fruit oolong | 180 g BQ-01 cold brew + 45 g fruit puree + 15 g syrup + 120 g water. | Fruit compatibility, cloudiness, acidity and sweetness. |
| Sparkling oolong | 180 g cold brew + 160 g sparkling water + 20 g syrup + ice for fresh trial. | Carbonation feel, aroma release and sweetness balance. |
Important RTD boundaries
- A fresh cold-brew formula is not automatically shelf stable.
- A cafe recipe is not automatically suitable for bottled distribution.
- Caffeine values require the exact formula and testing method.
- Fruit, milk, oat milk and sweeteners change safety, allergens and label requirements.
- Export, import, barcode, nutrition and claims rules depend on the destination market.
What to send before asking for a quotation
- Target market and channel: cafe bottle, supermarket, convenience store, online, distributor or foodservice.
- Product type: plain, fruit, sparkling, milk, tea coffee or functional-style concept.
- Package type and size: PET, glass, can, carton, pouch or foodservice concentrate.
- Expected first trial volume and monthly volume after launch.
- Required documents, certifications, lab tests and label constraints.
