Chai Concentrate Ratios and the Right Amount of Milk for Your Carton
Start with the dilution on your exact pack, then calculate the liquid you want before adding ice. A 1:1 concentrate needs a different pour from a 1:3 or 1:5 product, even when the brand names look familiar.
Published .
For 300 mL of prepared liquid, those three ratios use 150 mL, 75 mL and 50 mL of concentrate respectively. The rest is the milk specified by the manufacturer. The lookup and worksheet below show how to do the same calculation for your own drink.
This guide uses named North American products and manufacturer directions checked on 8 October 2026. Match the exact product and series; follow your current pack if its directions differ.
Find the ratio for the exact product
Read the preparation panel before using a recipe from another carton. In this guide, ratios always run concentrate to milk: 1:3 means one measure of concentrate plus three equal measures of milk.
On small screens, scroll the table sideways.
| Exact product | Manufacturer's starting ratio | Total parts of liquid |
|---|---|---|
| TAZO Classic Chai Latte concentrate, US 32-oz carton | 1 part concentrate + 1 part milk | 2 |
| Oregon Chai Original Chai Concentrate, US 32-fl-oz carton | 1 part concentrate + 1 part milk or dairy substitute | 2 |
| Say When Organic Authentic Chai, More to Pour series | 1 part concentrate + 3 parts milk or milk substitute | 4 |
| Oregon Chai Original Super Concentrate, US 64-oz jug | 1 part concentrate + 5 parts milk or soy | 6 |
The two Oregon Chai products make the distinction especially clear. The word “Original” appears on both, but Super Concentrate changes the preparation from equal parts to five parts milk for every part concentrate. The linked Kerry listings sell cases; the sizes above identify each individual container.
Say When's example is specifically its More to Pour Organic Authentic Chai. Do not extend that row to every product sold under the same brand.
These are preparation instructions, not a taste comparison. Different ratios do not establish that the finished drinks will have equal sweetness, spice intensity or texture.
Read parts as amounts added
For a 1:3 recipe, choose any convenient volume measure and use it four times in total:
- One measure of concentrate
- Three measures of milk
That makes the concentrate one-quarter of the measured liquid. “One part concentrate to three parts milk” does not mean the concentrate is one-third of the finished mixture.
For example, 75 mL concentrate plus 225 mL milk gives 300 mL. Using 100 mL concentrate plus 200 mL milk would give a 1:2 ratio instead.
Use the same volume unit throughout. A measuring jug marked in milliliters or fluid ounces works; ounces of weight on a scale are a different measurement.
Choose the liquid amount before the ice
A cup sold as 16 oz does not tell you how much liquid it will hold with your usual ice and room below the rim. The amount of ice and the space you leave both matter.
Choose the concentrate-plus-milk amount first. Measure and mix it in a jug, then pour it into a suitably sized cup and add the ice that fits. If you prefer filling the cup with ice first, allow room for the measured mixture; use a larger cup or less ice if needed.
Keep these three quantities separate:
- Cup capacity: the container's nominal size
- Prepared liquid: the measured concentrate plus milk
- Ice and headroom: additional space needed in the cup
The table below gives two different liquid targets. 300 mL and 12 US fl oz are separate examples, not equivalent volumes. Neither includes ice, melted ice or foam.
On small screens, scroll the table sideways.
| Concentrate-to-milk ratio | For 300 mL of liquid | For 12 US fl oz of liquid |
|---|---|---|
| 1:1 | 150 mL concentrate + 150 mL milk | 6 fl oz concentrate + 6 fl oz milk |
| 1:3 | 75 mL concentrate + 225 mL milk | 3 fl oz concentrate + 9 fl oz milk |
| 1:5 | 50 mL concentrate + 250 mL milk | 2 fl oz concentrate + 10 fl oz milk |
These quantities are calculated from the ratios above. For example, the 12-fl-oz 1:5 drink has six parts altogether: each part is 2 fl oz, so the milk accounts for five of them.
Calculate your own serving
For a label that says 1 part concentrate to N parts milk:
Concentrate = desired liquid amount ÷ (1 + N)
Milk = desired liquid amount − concentrate
Suppose your More to Pour carton calls for 1:3 and you want 360 mL of liquid. Divide 360 by 4 to get 90 mL concentrate. Subtract 90 from 360 to get 270 mL milk.
If you have already measured some concentrate, work in the other direction:
Milk to add = measured concentrate × N
For 60 mL of a 1:5 concentrate, add 300 mL milk. The resulting measured liquid is 360 mL, so check the cup size before pouring everything in.
A worksheet for your carton
- Exact product and series: __________
- Pack directions: 1 part concentrate + _____ parts milk
- Liquid to add, as specified on the pack: __________
- Desired concentrate-plus-milk amount: _____ mL or US fl oz
- Total parts, including the concentrate: _____
- Concentrate amount: desired liquid ÷ total parts = _____
- Milk amount: desired liquid − concentrate = _____
- Check: concentrate + milk = _____
- Cup has room for that liquid, plus any ice or foam: _____
Use these formulas only when the directions are written as one part concentrate to a stated number of parts milk. If your pack specifies other ingredients or a different preparation, follow that complete recipe.
Adjust the drink after establishing a baseline
Prepare a small serving at the pack's ratio first. Follow its shaking and heating instructions too. TAZO, for example, tells you to shake its Classic Chai concentrate, mix equal parts with milk, then heat or pour over ice. TAZO preparation directions
Once you have a repeatable starting drink, change one quantity at a time and write it down. If you replace some sweetened concentrate with milk, you reduce the tea, spice and sugar contributed by that concentrate together. The milk you choose can also contribute sweetness.
Adding water does not selectively remove sugar. If the concentrate amount stays the same, its sugar contribution stays the same; you have simply added more liquid. Replacing some concentrate with water reduces the amount of concentrate, including its tea and spices.
If you want less sweetness while keeping a particular chai intensity, changing the dilution alone may not give you both. Look at the current ingredients and preparation directions of a less-sweet product rather than assuming every concentrate can be adjusted independently.
When the pack does not answer the question
For an unidentified café concentrate, find the exact product and its official preparation directions before making a drink. A pump count from another recipe is not a usable volume unless the product and the amount delivered by that pump are both known.
Keep storage separate from dilution. Check your own concentrate and milk instructions, including what changes after opening. A ratio calculated correctly does not establish that an unfamiliar or improperly stored product is suitable to use.
The useful recipe to save is short: exact concentrate, label ratio, measured concentrate, measured milk and liquid amount before ice. That gives you a starting point you can repeat without borrowing the wrong carton's instructions.
