Guava and matcha is a high-margin “tropical + earthy” combo that sells on looks and repeat orders—if you can make it consistent. The problem is that guava and matcha both punish sloppy prep: guava can taste thin or overly sweet, and matcha clumps fast when the station’s busy.
If you’re aiming to catch both search behaviors, this SOP also naturally matches queries like iced guava matcha, guava matcha milk tea, and guava matcha latte recipe—but written the way operators actually need it.
This SOP gives you a staff-ready 16 oz matcha guava boba build using guava syrup, dairy milk, ice, and tapioca pearls, with a simple 50% sweetness default and quality checks that catch problems before customers do.
What you’re building (specs at a glance)
Cup size: 16 oz
Drink style: layered iced milk tea / latte-style
Default sweetness: 50%
Ice level: full ice (standard)
Topping: tapioca pearls included
Target experience: bright guava aroma + smooth matcha finish, no grit, no sour/curdled notes
Pro Tip: If you want the “three-layer” look every time, build in this order: boba → guava syrup → ice → milk → matcha. The order matters more than fancy tools.
Station setup (what staff needs)

Core ingredients
Matcha powder

Dairy milk
Simple syrup (optional, if your guava syrup isn’t your sweetness control)
Cooked tapioca pearls
Ice

Guava matcha recipe SOP: 16 oz boba build (50% sweet)
Ingredient targets (per 16 oz)
Use these as starting ratios, then lock your final spec after 1–2 days of staff tasting.
Cooked tapioca pearls: 50–60 g (about 1/4 cup)
Guava syrup: 20–30 mL
Matcha powder: 2–3 g
Water for matcha (warm): 45–60 mL
Dairy milk: 180–220 mL (top off after ice)
Ice: fill cup to the top
Sweetness control (simple rule):
Treat guava syrup as your primary sweetener for the 50% default.
If your guava syrup is very concentrated (or very light), adjust with small increments of simple syrup after the first test batch.
Step 1: Portion boba
Add 50–60 g cooked pearls to the cup.
Optional (recommended): add a small splash of brown sugar syrup or light simple syrup over pearls to keep them glossy.
Done when: pearls look shiny, not dry; they don’t stick in one big clump.
Step 2: Add guava syrup
Add 20–30 mL guava syrup directly onto the pearls.
Rotate the cup once so syrup lightly coats the bottom.
Done when: you can see a bright pink layer pooling at the bottom.
Step 3: Ice and milk
Fill the cup with ice to the top.
Pour in dairy milk until it reaches your normal 16 oz fill line (leave headspace for matcha).
Done when: milk is cold, cup is packed with ice, and the drink base looks clean (no “chunky” syrup).
Step 4: Make matcha (the clump-free method)
Matcha doesn’t “dissolve” like cocoa—it suspends. Your job is to create a smooth suspension that won’t break into gritty clumps.
Sift 2–3 g matcha into a small cup or bowl.
Add 45–60 mL warm water (aim roughly 140–180°F / 60–80°C).
Whisk/froth hard for 15–20 seconds in a zigzag motion until smooth and lightly foamy.
This warm-water range is a common best practice in iced matcha prep guides because it mixes the powder evenly without scorching it into bitterness (see the water temperature note in Preppy Kitchen’s iced matcha latte guide (updated 2026)). And if your shop sometimes tries “cold-only” mixing, note that multiple recipe sources stress that sifting is non-negotiable for cold matcha drinks if you want to avoid visible green lumps.
Done when: no visible powder specks; matcha looks glossy and uniform.
Step 5: Pour matcha + finish the layered look
Pour the matcha slowly over the ice.
Cap and serve layered (looks great) or shake once (more uniform flavor).
Done when: the drink has a vivid green top layer and customers can stir or shake before drinking.
Quality checks (quick, but catches 90% of issues)
Visual QC
Bottom: pink guava layer (not pale)
Middle: milk looks clean (not curdled)
Top: matcha is bright green (not dull/brown)
Texture QC
No gritty matcha dust at the end of the sip
Boba is chewy with no hard center
Flavor QC
Guava is present on first sip, matcha comes through on the finish
No “over-sweet” candy note
No sharp sour note (can happen if guava base is acidic and the build gets aggressively mixed)
Boba holding SOP (so the topping doesn’t ruin the drink)
Even a perfect guava matcha build gets complaints if the pearls are hard.
Cook pearls in smaller batches and hold them at room temp in syrup.
Many operator guides cite ~4–6 hours as the peak quality window before texture degrades; after that, you’ll often see hard centers or mushiness (one example: Chicken Pieces’ tapioca pearl guide (2026)).
Discard cues staff can use without arguing:
Pearls feel chalky or have a firm center
Pearls clump heavily even after stirring
Pearls taste stale or “doughy”
Troubleshooting (fast fixes during service)
“Matcha is clumpy”
Sift every time.
Use warm water for the matcha shot.
Switch to frother or a sealed shaker cup when the line is busy.
“Matcha tastes bitter”
Lower the water temperature and avoid boiling water.
Reduce matcha dose slightly (e.g., 3 g → 2.5 g per 16 oz).
Check whether staff is over-whisking with too-hot water.
“Guava tastes thin”
Increase guava syrup in small steps (e.g., +5 mL).
Reduce milk slightly to keep flavor intensity.
“Too sweet at 50%”
Drop guava syrup by 5 mL.
Keep the same matcha dose so the drink doesn’t turn bland.
“Layering looks muddy”
Add ice first, then milk, then matcha.
Pour matcha slowly onto ice.
(For the basic layering concept, see this guava matcha latte build example—we’re adapting the look for a faster syrup-based shop SOP.)
Optional upgrades (if you want a signature version)
Upgrade 1: Cheese foam top
A salty-sweet cheese foam turns this into a premium “dessert matcha” without changing the base drink.
Use your existing foam SOP, or reference BubbleTeaSuppliers.com’s HEYTEA-style cheese tea SOP for consistent service and apply it as a 25–35 mL top layer.
Upgrade 2: Two sweetness defaults (to reduce remakes)
Default A (menu standard): 50% sweet
Default B (fruit-forward): 70% sweet (same matcha, +5–10 mL guava syrup)
Train staff to recommend B when customers ask for “more guava.”

If you’re building a matcha menu that’s consistent across drinks—not just this one—start with BubbleTeaSuppliers.com’s bubble tea hub and the companion SOP for barista-level iced matcha latte ratios and techniques. You’ll get better consistency, faster training, and fewer “this tastes different today” complaints.
