What to check first

Brewer type and filter type

What are you using to brew your coffee? Drip machine, pour-over, French press? The method matters for strength. A paper filter will give a cleaner cup than a metal one. For milk tea, we want a robust coffee flavor, so consider a method that gives you control.

Water quality and temperature

Good water makes good coffee. If your tap water tastes off, your coffee will too. Filtered water is usually best. For brewing coffee, aim for water between 195-205°F. Too hot burns it, too cool under-extracts.

Grind size and coffee freshness

Freshly ground beans are a game-changer. Pre-ground coffee loses its zing fast. Grind size depends on your brewer. Coarse for French press, medium for drip, fine for espresso. Use beans roasted within the last few weeks for peak flavor.

Coffee-to-water ratio

This is crucial for strength. For coffee milk tea, you’ll want a higher coffee-to-water ratio than your usual cup. Think more coffee, less water. A good starting point might be a 1:10 ratio for a concentrate, but experiment.

Cleanliness/descale status

Is your coffee maker clean? Old coffee oils can turn a delicious drink bitter. If you haven’t descaled your machine in a while, now’s the time. A clean brewer means clean flavors.

Step-by-step (brew workflow)

1. Brew strong coffee.

• What to do: Use your preferred brewing method, but increase the coffee grounds or decrease the water. Aim for a concentrated brew. For example, if you normally use 2 tablespoons of coffee for 6 oz of water, try 3 or 4 tablespoons for the same amount of water.
• What “good” looks like: A rich, intense coffee liquid that smells amazing. It should be much stronger than your everyday coffee.
• Common mistake and how to avoid it: Brewing a standard cup of coffee. This won’t have enough coffee flavor to stand up to the tea and milk. Use more grounds or less water.

2. Brew strong black tea.

• What to do: Steep good quality black tea leaves in hot water. Use a ratio of about 1-2 teaspoons of loose leaf tea per 6 oz of water, or 1-2 tea bags. Let it steep for 3-5 minutes.
• What “good” looks like: A deeply colored, aromatic tea. It should have a robust flavor that you can still taste after adding other ingredients.
• Common mistake and how to avoid it: Over-steeping the tea, which makes it bitter. Stick to the recommended time.

To ensure you get the best flavor from your tea leaves, consider using a quality tea infuser. This allows the leaves to expand fully, releasing their full aroma and taste into the water.

3. Sweeten the tea.

• What to do: While the tea is hot, stir in your sweetener of choice. Sugar, simple syrup, or condensed milk work well. Start with a tablespoon or two and taste as you go.
• What “good” looks like: A pleasant sweetness that complements the tea without being cloying.
• Common mistake and how to avoid it: Adding too much sweetener at once. It’s easier to add more than to take it away.

4. Combine coffee and tea.

• What to do: Pour your strong brewed coffee into the sweetened tea.
• What “good” looks like: A beautiful amber-brown liquid. The aromas should start to meld.
• Common mistake and how to avoid it: Using weak coffee. The coffee flavor will get lost.

5. Add milk or creamer.

• What to do: Stir in your chosen milk or creamer. Evaporated milk is traditional for a richer taste, but half-and-half or even whole milk works. Start with about 1/4 to 1/2 cup per serving and adjust.
• What “good” looks like: A creamy, opaque beverage. The color should be a pleasing milky brown.
• Common mistake and how to avoid it: Using skim milk. It won’t provide the necessary richness and body.

6. Chill everything.

• What to do: Refrigerate the coffee-tea-milk mixture until it’s thoroughly cold. This can take a couple of hours.
• What “good” looks like: A cold, refreshing drink. Serving it warm just isn’t the same.
• Common mistake and how to avoid it: Skipping this step. A warm coffee milk tea is a sad coffee milk tea.

7. Prepare your serving glass.

• What to do: Fill a tall glass with ice.
• What “good” looks like: A glass packed with ice, ready to keep your drink frosty.
• Common mistake and how to avoid it: Not using enough ice. The drink will melt the ice too quickly and become watered down.

8. Pour and serve.

• What to do: Pour the chilled coffee milk tea over the ice.
• What “good” looks like: A visually appealing, cold beverage.
• Common mistake and how to avoid it: Pouring a hot mixture over ice. This melts the ice too fast.

9. Taste and adjust.

• What to do: Take a sip. Need more sweetness? More coffee flavor? Add a splash more of whatever you think it needs.
• What “good” looks like: A perfectly balanced drink that hits all the right notes for you.
• Common mistake and how to avoid it: Settling for a “just okay” drink. This is your chance to make it perfect.

Common mistakes (and what happens if you ignore them)

Decision rules (simple if/then)

• If your coffee tastes weak, then add more coffee grounds or use less water next time, because a strong coffee base is essential.
• If your tea tastes bitter, then shorten the steeping time next time, because over-extraction ruins the flavor.
• If the drink isn’t sweet enough, then add more sweetener gradually, because you can always add more.
• If the drink lacks creaminess, then use evaporated milk or half-and-half next time, because these provide richness.
• If the drink tastes watery, then chill your ingredients more thoroughly before mixing, because a cold base prevents ice melt.
• If you want a stronger coffee flavor, then brew your coffee at a finer grind size (if your brewer allows), because a finer grind can yield more extraction.
• If you detect off-flavors, then check your water quality and clean your equipment, because impurities can significantly impact taste.
• If the drink is too sweet, then add a bit more unsweetened brewed tea or coffee, because this will dilute the sweetness.
• If you want a bolder tea flavor, then use a higher quality loose-leaf tea, because premium teas have more robust profiles.
• If you’re short on time, then brew extra coffee and tea concentrate earlier in the day, because it will be ready to go when you are.

FAQ

How do I make the coffee concentrate?

You can make a concentrate by using more coffee grounds than usual for the amount of water, or by using less water. For example, brew your coffee using a 1:10 coffee-to-water ratio instead of the typical 1:15 or 1:17.

What kind of tea is best for coffee milk tea?

Black tea is the classic choice. Varieties like Assam, Ceylon, or a good quality English Breakfast blend work well because they have a robust flavor that can hold its own against the coffee.

Can I use instant coffee?

You can, but it might not give you the best flavor. Instant coffee can sometimes have a more artificial taste. If you must use it, dissolve it in a small amount of hot water to create a concentrated shot.

What’s the deal with evaporated milk?

Evaporated milk is a common ingredient in many traditional milk teas. It’s milk that’s had about 60% of its water removed, giving it a richer, creamier texture and a slightly caramelized flavor when heated.

How much sugar should I add?

This is totally up to your preference. Start with a tablespoon of sugar or simple syrup per serving and taste. You can always add more. Some people prefer condensed milk for sweetness, which also adds creaminess.

Can I make this ahead of time?

Yes, you can brew your coffee and tea, sweeten them, and combine them. However, it’s best to add the milk and ice just before serving to prevent separation or a watered-down taste. Store the coffee-tea base in the fridge.

What if I don’t have a fancy coffee maker?

No problem! A simple drip coffee maker, a French press, or even a Moka pot can work. Just focus on getting that strong, concentrated coffee flavor. Even a good quality instant coffee, dissolved well, can be a starting point.

How can I make it less sweet?

Reduce the amount of sugar or condensed milk you add. You can also increase the amount of unsweetened brewed tea or coffee to dilute the sweetness.
