How to Use Coffee Powder in a Bubble Tea Shop: Full Tutorial
If you're running a bubble tea shop in Australia and you've been eyeing the café next door's coffee line, the shortest path into coffee-boba drinks isn't an espresso machine. It's a 1 kg bag of coffee powder on your existing powder shelf. This tutorial walks through exactly how to use Original Coffee Powder shop-style — the ratios, the order of operations, the issues that trip up new operators — so you can add three or four solid coffee drinks to the board without rebuilding your setup.
We'll cover iced coffee milk tea, hot coffee milk tea, and a brown sugar coffee boba build, plus the common mistakes we see when a shop first puts coffee powder on the menu.
What coffee powder actually is (and isn't)
Original coffee powder is an all-in-one instant blend designed for high-volume drink preparation. It's not espresso. It's not drip. It's not a specialty single-origin you'd pour over at a Third Wave café — and trying to position it as that will disappoint coffee purists. What it is, is a consistent, forgiving ingredient that lets a bubble tea shop serve coffee-boba drinks at the same speed and margin as milk tea, without a barista, without calibration, and without pulling a new workflow into your counter.
The blend is built around spray-dried (instant) coffee with a creamer base, a small amount of cocoa powder for body, sugar, and flavour compounds. The cocoa note explains why the drink reads as slightly rounder and less acidic than straight instant coffee — it's closer to a coffee-mocha profile than to a pure black coffee profile. That's a feature, not a bug, for bubble tea customers who aren't ordering with the expectations of a third-wave coffee drinker.
The texture after dissolving is smooth and clean. Flavour-wise it sits between a strong cold-brew concentrate and a commercial-grade instant — more rounded than you'd expect, with enough body to stand up to milk, ice, brown sugar, or a tapioca stack.
That positioning matters for menu copy too. Don't call it "specialty coffee". Call it "shop-style coffee" or "boba coffee" — own what it is, and customers who come to you for bubble tea will order it on trust.
What you need on the counter
Before you start, stage the following:
- A 1 kg bag of Original Coffee Powder
- A warm-water dispenser or kettle (you'll prep with hot water even for iced drinks — this dissolves the powder cleanly)
- Your standard shaker cup
- A sweetener of your choice. We'll use Pure Cane Sugar Syrup / Fructose for clean coffee milk tea and Brown Sugar Syrup for brown sugar coffee boba
- A pitcher of milk (dairy or oat — both integrate cleanly with the powder; see the dairy note below)
- Freshly cooked Tapioca Pearls holding in brown sugar syrup
- Optional: Coffee Jelly as a topping
If you already serve brown sugar milk tea, you have most of this stock on the counter already.
Step 1 — Iced coffee milk tea (the default)
This is your baseline drink and the one we'd put on the menu first. The ratios below are typical shop starting points — always sanity-check against the preparation guidance on the bag and adjust by 5–10% to match how strong your customers like it.
- Measure 20 g of coffee powder into a shaker cup. (Start at 20 g per 500 ml serve; adjust up to 25 g if your customer base skews strong.)
- Add 80 ml of hot water (around 80–85°C). Stir or shake briefly to dissolve fully. This is the non-negotiable step — don't try to dissolve coffee powder in cold milk, you'll get grit.
- Add 15–20 ml of fructose to taste.
- Fill the cup with ice to the top.
- Pour in 280–300 ml of cold milk over the ice.
- Shake or stir through briefly to integrate.
Seal and serve. The drink should be a clean tan colour with no sediment pooling at the bottom.
If you're adding pearls, drop them in the cup first before the coffee mixture — the brown sugar syrup on the pearls bleeds up through the drink and gives you a natural layered look without any extra work.
Step 2 — Hot coffee milk tea (for autumn and winter)
Exactly the same drink, different temperature handling. This one earns its place on the board from late April onward.
- Measure 20 g of coffee powder into the serving cup directly (not a shaker — the drink never needs ice).
- Add 100 ml of hot water. Stir to dissolve.
- Add 15 ml of fructose.
- Add 300 ml of steamed or warmed milk. If you don't have a steam wand, warm the milk in a stainless jug on a pot of simmering water until it's hot to the back of the hand but not scalding. Dairy sits comfortably around 60–65°C; oat milk a touch lower.
- Stir through. Serve.
Don't add pearls to a hot drink from the cold-holding container. Warm them through briefly in the syrup they're sitting in — cold pearls pull the drink temperature down fast, and your customer gets a lukewarm cup.
Step 3 — Brown sugar coffee boba (the signature drink)
This is the build that genuinely turns heads. If you've ever run a brown sugar milk tea well, you already know the technique — this just swaps the milk tea base for coffee.
- In the serving cup, dribble 15–20 ml of [Brown Sugar Syrup](https://bubbletea-supply.com.au/products/brownsugarsyrup_5kg) around the inside wall, rotating the cup so it leaves stripes from rim to base. This is the "tiger stripe" effect — it's half the reason customers order the drink.
- Add a generous scoop of warm brown sugar pearls to the bottom.
- In a shaker, dissolve 20 g of coffee powder in 80 ml of hot water.
- Add another 10 ml of brown sugar syrup to the shaker for extra body. Stir to dissolve.
- Pour into the cup over the pearls.
- Top with 200–230 ml of cold milk. Do not shake or stir — the layering is the point.
Seal. When the customer pierces the lid, the layers integrate in the cup. This drink photographs well, which matters more than people admit.
Step 4 — Menu variations once the basics are locked
Once you've got the three drinks above running consistently, the next SKUs come cheaply:
- Coffee jelly milk tea — use the iced coffee milk tea base, add a scoop of Coffee Jelly as a topping. A customer ordering this is usually someone who likes coffee flavour but wants textural variety.
- Creamer-layered coffee — use the iced coffee milk tea base but replace half the milk with a scoop of 3 in 1 Milk Tea Powder dissolved in hot water, cooled, and floated on top. This gives a thicker, richer mouthfeel — closer to a Vietnamese-style iced coffee.
- Hot coffee oat latte — substitute oat milk, slightly lower sweetener. Sells well to the morning crowd if you're near any office foot traffic. See the dairy note below — oat milk does not make the overall drink dairy-free.
None of these require new stock. They're reuses of ingredients you already have.
What's in the bag (and what customers may ask)
Two ingredient-side points worth knowing before you build a coffee section on your board:
It's not dairy-free, even with oat milk. The coffee powder's creamer base contains whey powder and casein (milk proteins). Swapping in oat milk replaces the fresh milk in the build, but the powder itself still contributes dairy. For customers ordering specifically dairy-free or vegan, this product is not the right starting point — direct them to a different build (a tea-only iced drink, for example).
It's pre-sweetened, and the sweetener mix matters. The powder is sweetened during manufacture (sugar plus a small amount of an artificial sweetener, acesulfame potassium). That's a normal commercial formulation, but worth knowing for two reasons: dose your added syrup conservatively the first few drinks until you've calibrated to your shop's taste, and be ready to answer honestly if a customer asks about artificial sweeteners.
The full ingredient list and nutrition information are on the back of the bag, where Australian food law requires it. Customers who want the details can read it directly; you don't need to memorise the full list, just know the headline points above.
Common issues and how to fix them
Sediment pooling at the bottom. Cause: powder wasn't fully dissolved. Fix: always dissolve in hot water first, never cold milk. Stir for at least 5 seconds before adding anything else.
Grainy or grit-on-tongue mouthfeel. Same root cause as sediment — incomplete dissolution. A quick shake in the shaker cup with hot water alone (before milk or ice) catches this.
Drink tastes flat or under-strength. Dosage is low, or the water you used wasn't hot enough to fully extract. Bump to 22–25 g per 500 ml, and make sure your hot water dispenser is holding above 80°C.
Drink tastes too bitter. You've over-dosed or the coffee sat too long in hot water before milk was added. Prep one drink at a time during quieter periods rather than batching.
Drink tastes too sweet straight off the build. The powder is pre-sweetened. Cut your added syrup by 20–30% from the standard milk-tea dose and re-test. Most operators land at 10–15ml of fructose for the standard coffee milk tea, not the 15–20ml they'd use on a plain milk tea.
Clumping in the bag. Seal the bag properly after each use and keep it somewhere cool and dry. Coffee powder is hygroscopic — it pulls moisture from humid air and hardens. In a Brisbane or Cairns summer, this matters more than in Melbourne.
Separation over time if the drink sits. This can happen with oat milk specifically. Shake integration is key; remind staff to shake through, not just pour and stir.
Where coffee powder fits on your menu
A few thoughts on menu placement that we've seen work across shops we supply:
Group coffee-boba drinks together on the board as their own small section — three or four SKUs, clearly labelled — rather than sprinkling them through the milk tea section. Customers who want coffee find it at a glance; customers who don't aren't confused.
Price coffee-boba drinks at or just slightly above your milk tea tier. Customers psychologically expect coffee to cost a little more than tea, and you've given them the "speciality" framing without having to back it with barista equipment.
If you're near any cafés or office buildings, push the hot version in the mornings (8–11 am) and the iced brown sugar coffee boba through lunch. This captures two completely different order profiles off the same powder.
Adding coffee to the board
If you've been meaning to test coffee-boba drinks and kept putting it off because you thought it needed an espresso setup — it doesn't. A single bag of Original Coffee Powder and the stock you already run will get you three solid menu items by end of this week.
Stage the counter once, train your staff on the three ratios above, and let your first few customer orders tell you which version your shop's crowd actually prefers. Most operators we talk to find the brown sugar coffee boba pulls the numbers fastest, with the hot version building a quieter but loyal morning following through autumn and into winter.
