How to Make Tea Concentrate for Bubble Tea: Ratios & Tips
How to Make Tea Concentrate for Bubble Tea: Ratios, Brewing & Storage
Making tea concentrate for bubble tea is a simple way to prepare a strong tea base before adding milk, fruit flavor, sweetener, or ice. Start with about 20 grams of loose-leaf tea and 500 ml of water as a practical black tea concentrate recipe, then adjust the strength to suit your tea and drink. Once brewed and strained, the concentrate is ready to use in milk tea, fruit tea, and other bubble tea drinks.
For home users, tea concentrate can make drink preparation easier. For bubble tea shops, it can help staff prepare drinks more consistently and serve customers faster.
What Is Tea Concentrate for Bubble Tea?
Tea concentrate is brewed tea that is stronger than the tea you would normally drink on its own. You prepare it using more tea leaves for a given amount of water, then dilute it when making the final drink.
For example, you can brew a strong black tea base and later combine a measured amount with milk, sugar syrup, and ice to make milk tea.
A tea concentrate is different from a milk tea powder mix. A concentrate comes from brewed tea leaves or tea bags, while a powder mix is a separate ingredient that you prepare according to its product instructions.
Bubble tea shops often benefit from preparing the tea base separately because each drink can then follow a consistent recipe.
Ingredients and Equipment
For a basic batch, you need:
20 grams of loose-leaf black tea
500 ml of fresh water
A kitchen scale or measuring spoon
A kettle or suitable heating equipment
A heat-resistant brewing container
A fine strainer
A clean container with a lid for storage
The amounts above are a starting recipe, not a universal formula. Different tea varieties, leaf sizes, and suppliers can produce different results.
If you use tea bags, begin with approximately twice the normal number of bags for the same volume of water. Check the instructions on the package and adjust the strength after testing the finished drink.
How to Make Tea Concentrate for Bubble Tea
Step 1: Measure Your Tea and Water
Measure the tea before heating the water.
For the starter recipe, use 20 grams of black tea with 500 ml of water. Weighing the tea gives you a more repeatable result than estimating the amount by eye.
For a larger batch, you can scale the ingredients proportionally:
Water | Loose-leaf black tea |
500 ml | 20 g |
1 litre | 40 g |
2 litres | 80 g |
These measurements are starting points for a strong concentrate. You may need to adjust the quantities for your particular tea.
Also remember that the finished liquid volume will be lower than the original water volume because some water remains in the tea leaves.
Step 2: Heat the Water to the Right Temperature
Water temperature affects how tea releases its flavor.
For many black teas, use water close to boiling, around 95–100°C (203–212°F). For green tea, a lower temperature near 80°C (176°F) is a useful starting point.
Green tea can become bitter if you use water that is too hot or steep it for too long. Always check the tea supplier's preparation instructions when they are available.
Step 3: Steep the Tea
Add the tea leaves to the hot water and allow them to steep.
Use these starting ranges:
Tea type | Water temperature | Starting steep time |
Black tea | 95–100°C | 3–5 minutes |
Green tea | Around 80°C | 1–3 minutes |
Oolong tea | Depends on the variety | Follow supplier guidance |
A concentrate needs to deliver enough flavor to remain noticeable after you add milk, water, or ice. However, leaving tea leaves in water for too long is not always the best way to increase strength.
If the concentrate tastes bitter, try increasing the amount of tea slightly while keeping the steeping time controlled.
For more brewing guidance, see the Tea and Herbal Association of Canada's tea-brewing guide.
Step 4: Strain the Tea Immediately
Remove the tea leaves or tea bags as soon as the chosen steeping time ends.
If you leave them in the liquid, extraction continues and can make the concentrate harsher than you intended.
Use a clean strainer and transfer the tea into a suitable container. Avoid squeezing tea bags or leaves aggressively if that makes your particular tea taste more bitter.
Step 5: Let the Concentrate Cool Safely
If you plan to serve iced drinks, cool the concentrate promptly.
For a larger batch, divide it into smaller, clean containers so it can cool faster. Keep the container covered where practical, and refrigerate the concentrate promptly rather than leaving a large pot at room temperature.
For more consistent results, prepare plain tea concentrate and add milk, syrups, and toppings when you make each drink.
Step 6: Test the Flavor Before Using It
Taste a small amount of the concentrate before preparing the full drink.
It should be stronger than ordinary drinking tea, but it should not taste unpleasantly bitter or harsh.
The important test is how it tastes after dilution. A strong concentrate should retain its tea character when you combine it with milk, fruit flavor, sweetener, or ice.
What Is the Best Tea Concentrate Ratio for Bubble Tea?
There is no single ratio that works for every tea or beverage. A useful starting point is to brew a concentrate that is roughly two to three times as strong as the regular tea you would normally prepare.
At serving time, begin with a ratio of one part concentrate to one part additional liquid, then adjust according to taste.
For example:
One part concentrate plus one part milk creates a starting point for milk tea.
One part concentrate plus one part water creates a starting point for a lighter tea drink.
One part concentrate plus two parts liquid creates a milder drink if your concentrate is very strong.
These ratios are starting points rather than fixed industry standards. The final drink also depends on ice dilution, added syrup, milk, fruit ingredients, and the intended serving size.
For bubble tea shops, write down the final amounts after testing the full drink. This makes it easier for every staff member to follow the same recipe.
How to Use Tea Concentrate for Milk Tea
You can use black tea concentrate to prepare classic milk tea without brewing a new batch for every order.
For an initial test in a 16-ounce cup, try:
100–120 ml of chilled black tea concentrate
90–120 ml of milk
Sugar syrup to taste
Ice to fill the cup
Cooked tapioca pearls, if desired
Mix the concentrate, milk, and sweetener first. Taste the mixture and then pour it over ice. Add the tapioca pearls when preparing the finished drink.
This is a recipe-development starting point, not a finished formula for every tea. Adjust the amounts until the drink has the tea strength, creaminess, and sweetness you want.
If your milk tea tastes too weak, check the strength of the tea base before adding more sugar. Sweetness can change the flavor balance, but it does not replace the depth of a properly brewed tea.
How to Use Tea Concentrate for Fruit Tea
Tea concentrate can also form the base of fruit tea.
For a 16-ounce test drink, start with:
100–120 ml of chilled tea concentrate
120–160 ml of cold water
Fruit syrup or another suitable fruit ingredient, according to its instructions
Ice
Stir the tea and water together before adding the fruit ingredient. Taste the mixture and adjust the flavor gradually.
You can use a suitable black, green, or oolong tea depending on the fruit flavor and the style of drink you want to create. A lighter tea may work well when you want the fruit flavor to stand out, while a stronger tea may suit a bolder recipe.

Can You Make Tea Concentrate Ahead of Time?
Yes. Preparing the tea base ahead of service can save time, particularly when a shop makes a high volume of drinks.
However, prepare the batch in a way that supports both food safety and drink quality.
For best results:
Use clean brewing equipment and a clean storage container.
Strain the tea after the intended steeping time.
Cool it promptly in smaller containers when necessary.
Keep it covered and refrigerated.
Add milk and other ingredients when making each order.
Label the batch with its preparation date and time.
For conservative handling, refrigerate prepared concentrate within two hours, keep the refrigerator at 4°C (40°F) or below, and use it within three to four days at most. These are general refrigerated-leftover guidelines, not a validated shelf-life study for every tea concentrate. Follow stricter local food-service rules whenever they apply.
For everyday café service, preparing fresh concentrate each day is a sensible way to maintain flavor and simplify batch management.
Never rely on smell or appearance alone to determine whether a stored drink is safe.
Common Problems When Making Tea Concentrate
The Concentrate Tastes Too Bitter
You may have used water that was too hot for the tea, steeped it for too long, or used a tea variety that becomes harsh when concentrated.
Try reducing the steeping time, following the supplier's temperature guidance, or testing a slightly different amount of tea.
The Tea Tastes Too Weak After Adding Milk
Your concentrate may not be strong enough, or the milk quantity may be too high.
Test the tea-to-water ratio first. Then adjust the milk amount gradually until the tea remains noticeable.
The Drink Tastes Watery
Ice may be melting too quickly, or your concentrate may be too weak for the final amount of liquid.
Test the drink at serving temperature rather than evaluating it only before adding ice. Use consistent ice portions and measure the other ingredients.
Every Batch Tastes Different
Inconsistent measurements, steeping times, water temperatures, or tea quantities can change the result.
Use a scale, a timer, and written preparation instructions. If a recipe works well, record the exact quantities and repeat them rather than relying on memory.
The Drink Is Too Sweet
Some syrups, powders, and toppings already add sweetness.
Prepare the tea concentrate without unnecessary sweetener, then adjust the final drink after checking the sweetness of the other ingredients.
Hot-Brewed vs. Cold-Brewed Tea Concentrate
You can prepare a tea base using hot water or a cold-brewing method.
Feature | Hot-brewed concentrate | Cold-brewed concentrate |
Preparation | Uses heated water | Uses cold water |
Time | Usually a few minutes | Usually several hours |
Flavor | Depends on tea and brewing method | Often smoother, depending on the tea |
Planning | Can be prepared closer to service | Requires advance preparation |
Best method | Follow the tea's hot-brewing instructions | Follow the tea supplier's cold-brewing guidance |
Cold brewing can work well for some tea-based drinks, but it requires planning because the process takes much longer. Keep the tea refrigerated while cold brewing, use clean equipment, and test the result with the full bubble tea recipe.
Do not assume cold brewing is automatically safer or that every tea needs the same steeping time.
How Bubble Tea Shops Can Standardize Tea Concentrate
A repeatable process helps shops maintain flavor across different shifts and employees.
Create a written recipe that records:
Tea variety and batch quantity
Water volume and temperature
Steeping time
Straining method
Approximate finished yield
Concentrate quantity per drink
Milk or water quantity
Sweetener and topping portions
Cooling, refrigeration, and batch-labeling steps
Test the recipe in the actual serving cup, including ice and toppings. Record what works, and change one variable at a time if the result needs improvement.
For larger operations, consider using a simple batch sheet to record preparation time, the person who prepared the batch, and the amount remaining. Follow applicable local food-safety requirements and your business's food-safety procedures.
The goal is not to make the strongest possible tea. It is to make a tea base that produces a balanced, repeatable final drink.
Frequently Asked Questions
How much tea should I use for 500 ml of water?
For a strong black tea concentrate, start with around 20 grams of loose-leaf tea per 500 ml of water. Adjust the amount for your tea variety, supplier instructions, and desired strength.
How long should I steep tea for bubble tea?
A common starting range is three to five minutes for black tea and one to three minutes for green tea at a suitable temperature. Check the supplier's brewing guidance, because tea varieties differ.
Can I use tea bags to make bubble tea concentrate?
Yes. Start with roughly twice the normal number of tea bags for the same amount of water, then adjust after testing the finished drink. Bag size and tea strength vary by product.
Should I add milk before storing tea concentrate?
It is usually more practical to store the plain tea base and add milk when preparing each drink. This also makes it easier to use the same concentrate for different beverages.
Can I use green tea concentrate for bubble tea?
Yes. Green tea concentrate works in suitable fruit teas and other tea-based drinks. Use a temperature and steeping time that suit the specific green tea.
How long does tea concentrate last in the refrigerator?
