If you run a bubble tea or coffee shop, you’ve likely noticed two green-tea stars driving premium orders: matcha and Longjing (Dragon Well). This guide gives you operator-grade recipes, parameters, and SOPs to produce consistent, great-tasting drinks—while managing batching, holding, and food safety. We’ll cover quick-start recipes, the science behind ingredients, scaling math, troubleshooting, and menu positioning. Let’s dig in.
Quick-start recipes
Below are three shop-ready builds. Use them as baselines, then tune to your milk, ice program, and sweetness profile.
Classic Matcha Milk Tea (16 oz / 500 ml)
Baseline (iced or hot):
Matcha: 3 g, sifted
Water: 100 ml at ~80°C / 176°F
Whisk: 10–15 seconds in a fast “M” motion for fine foam
Milk: 200–250 ml dairy (whole/2%) or plant (oat/soy), temperature per service style
Sweetener: 10–20 ml 1:1 simple syrup (adjust to taste)
Steps
Sift 3 g matcha into a bowl. Add 100 ml water at ~80°C. Whisk 10–15 s until smooth and lightly foamy. These parameters mirror the latte workflow described in Ippodo’s cafe guidance for usucha-strength preparation and lattes; see the method in the Ippodo matcha latte recipe (accessed 2026), which emphasizes sifting and ~80°C water.
For iced: Fill a 16 oz cup with ice to the top line. Add syrup, milk, then matcha. Stir or brief shake to integrate. Ippodo’s iced latte method supports the iced workflow using the same temperature logic.
For hot: Warm or steam milk to 55–60°C (131–140°F) for optimal sweetness; combine with whisked matcha; add syrup to taste.
Small-batch concentrate (yields ~10 iced servings)
Matcha: 30 g, sifted
Water: 1 L at ~80°C / 176°F
Method: Whisk in portions for full dispersion; strain through fine mesh if needed. Chill rapidly; keep cold ≤5°C / 41°F; rewhisk before service. For color and aroma, use within the same day. Technique choices (sifting, 10–15 s whisk) are consistent with Ippodo’s latte preparation notes.
Longjing Milk Tea (16 oz / 500 ml)
Two options: brew-to-order or use a mild concentrate for peak times.
Per-cup brew-to-order (iced or hot)
Longjing leaves: 2.5 g
Water: 180 ml at 80–85°C (176–185°F)
Time: 3–4 minutes; then strain immediately
Milk: 150–200 ml
Sweetener: 10–20 ml 1:1 simple syrup
Steps
Brew leaves at 80–85°C for 3–4 minutes. Strain promptly. Many producer pages—such as Teavivre’s Dragon Well guides—recommend around 85°C for balanced extraction; see Teavivre’s Premium Dragon Well parameters.
For iced: Add syrup to a 16 oz cup with ice; pour tea, then milk; stir.
For hot: Combine hot tea with warm milk (55–60°C); add syrup.
Rush-hour concentrate (yields ~16 iced servings at 150 ml tea per cup)
Longjing leaves: 50 g
Water: 3 L at 82–85°C (180–185°F)
Time: 3 minutes; agitate gently; strain promptly
Target mix: 150 ml concentrate + 150 ml milk in-cup; sweeten with syrup
Cooling: Ice bath or blast chill to ≤5°C / 41°F as quickly as feasible; hold cold
Note: Using the higher end of temperature and dose produces a milk-compatible base while managing bitterness. Validate with a brief sensory check per lot. Retailer/producer guidance like Harney & Sons’ Lung Ching notes also align around ~175–185°F with ~3 minutes, supporting these windows.
Signature Fusion: Matcha + Longjing (Layered)
Prepare matcha phase as above (per-cup). Brew Longjing at ~80°C for 2.5–3 minutes for a softer profile.
Cup build (iced): Ice to top line; 10–15 ml syrup; 150 ml milk; 120 ml Longjing; float freshly whisked matcha (60–80 ml) on top for a two-tone visual. Stir before drinking on request.
Ingredient science: matcha vs Longjing
Matcha is a stone-milled powder of shade-grown green tea; you drink the particles themselves. Longjing is pan-fired green tea brewed as an infusion; you drink extracted compounds from intact leaves. In milk, matcha’s fine particles deliver saturated color and texture. Longjing yields a lighter jade hue with fragrant, nutty notes.
Why milk softens green tea’s bite
Casein proteins in dairy can bind green tea catechins, reducing perceived astringency and bitterness; fats add body and smooth edges. A 2024 peer‑reviewed overview discusses milk protein–polyphenol interactions that stabilize polyphenols while moderating bitterness; see the 2024 review on milk protein–polyphenol conjugates. Trade summaries echo the mechanism that casein micelles interact with EGCG, moderating harshness.

Shop parameters and SOPs for matcha Longjing milk tea
This section summarizes the critical controls you’ll use daily, with tolerances.
Matcha preparation controls
Dose: 2–3 g per 16 oz serving (adjust for milk fat and sweetness).
Water: ~80°C / 176°F; too hot can taste harsh.
Sifting: Always sift to prevent clumps.
Whisking: 10–15 seconds in fast “M/W” motion until microfoam forms. Chasen, electric whisk, or micro‑frother all work; train for consistency. These cues reflect the latte workflow shared by Ippodo and café‑training features in the specialty coffee press.
Longjing extraction controls
Temperature: 80–85°C (176–185°F) for balance; many producers specify ~85°C for Dragon Well.
Ratio: For milk tea, brew slightly stronger: 2.5 g per 150–200 ml.
Time: 3–4 minutes; strain promptly to avoid bitterness. Producer guidance such as Teavivre’s Premium Dragon Well supports these windows.
Milk base choices and sweetness
Dairy: Whole or 2% often binds astringency better and adds body; warm hot drinks to ~55–60°C for sweetness without scorched notes.
Plant-based: Soy (higher protein) often offers stronger foam and astringency reduction; oat adds creaminess with neutral flavor. For nutrient baselines, see USDA FoodData Central entries such as oat milk per 100 g; brand-to-brand variability is high—run bench tests.
Sweeteners: For iced formats, use 1:1 simple syrup for instant dispersion; consider 2:1 rich syrup when you want higher sweetness with less dilution. Practitioner guides like A Bar Above’s simple syrup overview outline standard ratios for cold drinks.
Batching, scaling, and costing
Scaling math examples
Longjing concentrate above (50 g in 3 L for 3 minutes at ~83°C) yields 3,000 ml of base. At 150 ml per cup, you’ll serve ~20 iced drinks. If your profile prefers 120 ml tea + 180 ml milk, the same batch yields ~25 drinks. Adjust leaf dose upward if milk mutes aroma with your SKU.
Matcha batch at 30 g in 1 L water yields ~10 robust iced servings at 100 ml per cup; rewhisk before use to re‑suspend particles.
Holding windows and ice/dilution
Brew Longjing fresh, then chill rapidly and cold‑hold at ≤5°C / 41°F. For iced builds, account for ~25–30% dilution from ice in typical 16 oz cups; compensate by slightly stronger tea or richer syrup.
Avoid holding matcha mixed with milk for long periods; prepare matcha phase close to service. If you must pre‑batch, keep phases separate (tea vs milk/syrup) and rewhisk before service.
Yield and waste control
Weigh leaves and matcha daily; track TDS or simple sensory benchmarks (color and aroma) against a standard cup photo. Log brew start/end times and temps. Standardize syrup pumps to ml for consistency.
Food safety and holding
This guidance aligns with widely adopted food codes; always confirm local regulations.
Cold holding for milk-containing beverages is generally maintained at 41°F (5°C) or below. The U.S. standard reference is FDA Food Code 2022, which describes time/temperature control for safety (TCS) foods.
Hot holding is generally maintained at 135°F (57°C) or above per the Food Code 2022.
Cooling hot liquids quickly is essential; common methods include shallow pans, ice baths, stirring, and blast chilling. The FDA describes cooling from 135°F to 70°F within 2 hours and to 41°F within a total of 6 hours for applicable foods; see the Food Code 2022 PDF. Apply equivalent caution to tea concentrates you heat, and document procedures in your SOPs.
Allergen and labeling: Clearly identify dairy and soy/oat options; avoid cross‑contact by separating pitchers and rinsing tools between builds.
Troubleshooting and QA
Issue Likely cause Fast fix
Bitter Longjing base Temp too high or time too long Drop to ~80°C; shorten to 2.5–3 min; add slightly richer milk
Flat or weak aroma Under‑dosed leaves or low temp Increase leaves to 2.5–3 g/180 ml; brew at 83–85°C
Matcha clumps Not sifted; water too cool; poor whisking Sift; target ~80°C; whisk 10–15 s in fast “M” motion
Separation in cup Insufficient dispersion or long hold Rewhisk matcha; brief shake before serving; avoid long pre‑mix holds
Foam collapse (plant milks) Low protein or non‑barista formula Try soy or barista‑oat; adjust milk temp profile
QC tolerances
Visual: Matcha should show a uniform jade layer with fine bubbles; Longjing base should be clear to lightly opalescent, pale jade.
Taste: Bitterness acceptable but not dominant; sweetness integrated without grit.
Process: Brew temp within ±2°C of target; steep time within ±15 s; syrup dosing within ±2 ml.
Menu positioning and pricing signals
Position both drinks under “Signature Green Tea” with provenance cues: Uji‑style matcha; Hangzhou Longjing. Offer hot and iced. Use sensory copy like “chestnut‑nutty Longjing with a clean jade finish” and “creamy, umami‑forward matcha.”
Create a seasonal variant: yuzu‑matcha Longjing spritz (half‑strength milk, citrus syrup) for warmer months; warm koicha‑inspired matcha with micro‑foamed milk for winter (keep water ~80°C to avoid harshness).
Bundle upsells: add-on boba, grass jelly, or light salted cream caps. Keep toppings proportionate so tea character remains clear.
Next steps and sourcing
If you’re building a green‑tea program or vetting SKUs, a neutral place to start is the catalog at Bubble Tea Supplier, which lists matcha and green‑tea options suitable for shop trials. Evaluate lots with your own bench tests for dose, temp, and milk compatibility.
