How to Make Iced Mix Coffee
Combine instant mix coffee packets and black instant coffee packets at roughly a 3-to-1 ratio and dissolve them in a small amount of hot water, adding the water gradually and stirring until the mixture is thick and syrupy. Pour the concentrate into a narrow-nozzle squeeze bottle and refrigerate it. To serve, fill a glass with ice and milk, then squeeze in as much concentrate as you like.
A convenient, batch-friendly iced coffee made by dissolving instant mix coffee and black instant coffee together into a thick concentrated extract, stored in a squeeze bottle in the refrigerator, and poured over ice and milk on demand.
Ratio
3 instant mix coffee packets : 1 black instant coffee packet (baseline; adjust downward for smaller-format black coffee packets)
What you need
- heatproof cup or small container
- spoon or stirrer
- narrow-nozzle squeeze bottle
Method
Place your instant mix coffee packets and black instant coffee packets together in a heatproof cup or container
The creator's baseline is 3 mix coffee packets to 1 black instant coffee packet. For smaller-format black coffee packets, use 2 mix packets to 1 black; for the very smallest formats, a 1-to-1 ratio is fine. These are starting points — adjust freely to your own taste.
Expert tipThe balance between the sweet, creamy mix coffee and the stronger black coffee is what makes the blend interesting. Neither type alone gives the same depth.
Add hot water a little at a time, stirring continuously, until all the coffee is fully dissolved into a thick, syrupy concentrate
Add water gradually rather than all at once so you can control the consistency. The finished concentrate should flow in a steady, viscous stream — not thin and watery.
Expert tipResist the urge to add extra water for convenience. A thicker concentrate is far more versatile and will not water down your drink.
Let the concentrate cool slightly, then pour it into a narrow-nozzle squeeze bottle
The nozzle opening should be small — roughly the size of a coffee bean — so the liquid shoots in a controlled stream rather than spilling. Choose a well-made bottle; a flimsy or wide-mouthed one will make the pour messy and uncontrolled.
Seal the bottle and store it in the refrigerator until you are ready to drink
The bottled concentrate keeps in the fridge and can be pulled out whenever you want a quick iced coffee. You can make a larger batch and use it across several servings.
When ready to serve, fill a glass with ice and pour in your milk or preferred cold liquid
Use as much or as little milk as you like. For a layered, cafe-style look, add the milk over the ice first, before adding the coffee concentrate.
Point the squeeze bottle nozzle at the surface of the drink and squeeze the coffee concentrate in steadily
Squeezing through the narrow nozzle creates a clean, layered pour. For a larger glass use more concentrate; for a smaller serving use less.
Expert tipAdd concentrate gradually and taste as you go — the right amount is entirely personal, and you can always add more.
Stir, taste, and adjust the milk-to-coffee ratio to suit your preference before serving

Why this works
Combining sweet, creamy instant mix coffee with stronger black instant coffee in a single concentrate creates a balance that neither type achieves on its own — the mix coffee rounds out the bitterness while the black coffee adds depth. Using minimal hot water keeps the concentrate dense enough that it does not dilute the final drink when poured over ice. Storing the concentrate in a squeeze bottle keeps it airtight in the refrigerator and gives precise, controlled portion delivery at serving time. The narrow nozzle lets you layer the coffee into the glass in a single smooth stream without disturbing the ice or milk.

Where beginners go wrong
- 1
Squeeze bottle nozzle keeps getting clogged
The coffee was not fully dissolved before bottling. Stir more vigorously and add a touch more hot water if needed, until there are absolutely no granules remaining. Do not rush this step — undissolved particles are the main cause of blockages.
- 2
Concentrate is too weak or too strong
Adjust the ratio of mix coffee packets to black coffee packets to suit your taste. More mix packets makes the concentrate sweeter and creamier; increasing the proportion of black coffee makes it stronger and more bitter. The ratios in this recipe are personal baselines, not fixed rules.
- 3
The finished drink tastes watery
The concentrate was likely made with too much water, making it thin rather than syrupy. Use less water next time and stir longer. You can also squeeze more concentrate into the glass at serving time.
- 4
The squeeze bottle leaks or is hard to control
Use a squeeze bottle with a firm, narrow nozzle opening. Soft-tipped or wide-mouthed bottles release liquid too freely. A bottle with a nozzle opening roughly the size of a coffee bean gives the cleanest, most controlled pour.
What you should taste
The concentrate blends the sweetness and creaminess of mix coffee with the body and slight bitterness of black instant coffee, resulting in a balanced, smooth iced drink that is neither cloying nor harsh. Over ice with milk it is refreshing and easy to drink.
FAQ
Do I have to use a specific brand of instant mix coffee or black coffee?
No. The video references specific products only as examples of packet sizes and strengths. The technique works with any instant mix coffee combined with any black instant coffee. Match your ratio to the relative size and intensity of the packets you have and adjust to your own taste.
Can I use something other than milk?
Yes. The creator mentions coconut water as one alternative, and notes broadly that the liquid base and the amount of concentrate added are entirely up to personal preference.
How long does the bottled concentrate keep?
The creator stores the concentrate in the refrigerator and uses it as needed across multiple servings. As a general rule for dissolved coffee concentrates, keep it chilled and use it within a few days for the best flavor.
