What to check first

Brewer type and filter type

The type of brewer you use will influence the strength and clarity of your coffee. Drip machines, pour-overs, and French presses are common. For hot milk coffee, a cleaner cup is often preferred, so paper filters (common in drip and pour-over) can be beneficial. If using a French press, ensure the plunger is fully engaged to minimize sediment.

Water quality and temperature

Filtered water is ideal for brewing coffee, as tap water can contain minerals that affect taste. For hot milk coffee, the water used to brew the coffee should be hot, typically between 195-205°F (90-96°C), but not boiling. The milk, however, will be heated separately to a lower temperature.

Grind size and coffee freshness

A medium-fine grind, similar to table salt, is generally a good starting point for most brewing methods used for hot milk coffee. Coffee beans should be freshly roasted and ground just before brewing for the best flavor. Stale coffee can result in a dull or bitter taste, even with the addition of milk.

Coffee-to-water ratio

The ratio of coffee grounds to water is crucial for achieving the desired coffee strength. A common starting point is between 1:15 and 1:17 (e.g., 1 gram of coffee to 15-17 grams of water). For hot milk coffee, you might want a slightly stronger brew than you’d typically use for black coffee, as the milk will dilute the flavor.

Cleanliness/descale status

A clean brewer and kettle are essential for good-tasting coffee. Mineral buildup from hard water can affect brewing temperature and introduce off-flavors. Regularly descale your coffee maker and clean all brewing components according to the manufacturer’s instructions.

Step-by-step (how to make hot milk coffee)

1. Gather your ingredients and equipment.

• What to do: Have your coffee beans, milk (dairy or non-dairy), coffee brewer, filter (if applicable), kettle, and a mug ready.
• What “good” looks like: Everything is within easy reach and clean.
• Common mistake: Forgetting an ingredient or realizing your brewer needs cleaning mid-process. Avoid this by having everything prepared beforehand.

2. Heat your water for brewing.

• What to do: Heat fresh, filtered water in your kettle to the optimal brewing temperature, typically 195-205°F (90-96°C).
• What “good” looks like: Water is hot but not actively boiling.
• Common mistake: Using boiling water, which can scorch the coffee grounds and lead to bitterness. Let boiling water sit for about 30 seconds before brewing.

3. Grind your coffee beans.

• What to do: Grind your coffee beans to a medium-fine consistency, similar to table salt.
• What “good” looks like: Freshly ground coffee with an aromatic scent.
• Common mistake: Using pre-ground coffee that has lost its aroma, or grinding too fine (which can clog filters and lead to over-extraction) or too coarse (leading to weak coffee).

4. Prepare your brewer.

• What to do: If using a paper filter, rinse it with hot water to remove any papery taste and preheat the brewer. If using a French press, ensure it’s clean and ready.
• What “good” looks like: The brewer is warm and free of any residual grounds.
• Common mistake: Not rinsing paper filters, which can impart a papery taste to your coffee.

5. Add coffee grounds to the brewer.

• What to do: Measure your coffee grounds using your desired ratio (e.g., 1:15 to 1:17). For a standard 8 oz mug, this might be around 15-20 grams of coffee.
• What “good” looks like: The correct amount of coffee grounds are evenly distributed in the filter or brewer.
• Common mistake: Inaccurate measuring, leading to coffee that is too weak or too strong. Using a scale is the most precise method.

6. Brew your coffee.

• What to do: Pour the hot water over the coffee grounds according to your brewer’s instructions. For pour-over, bloom the grounds for 30 seconds, then pour slowly. For a drip machine, let it run its cycle. For a French press, steep for 4 minutes.
• What “good” looks like: The coffee is brewing evenly, and the aroma fills the air.
• Common mistake: Pouring water too quickly or unevenly, which can lead to uneven extraction and a less flavorful cup.

7. Heat your milk.

• What to do: While coffee brews, gently heat your milk in a saucepan or microwave to your preferred temperature, ideally between 140-155°F (60-68°C). Avoid boiling the milk, as it can scald and change its flavor.
• What “good” looks like: Milk is hot to the touch but not bubbling or steaming excessively.
• Common mistake: Overheating the milk, which can create a skin and a burnt taste. Use a thermometer if unsure.

8. Strain or press your coffee.

• What to do: Once brewing is complete, remove the filter or press the plunger on your French press.
• What “good” looks like: You have a clear, brewed coffee concentrate ready to be mixed.
• Common mistake: Letting the coffee sit too long in the brewer after brewing, which can lead to over-extraction and bitterness.

9. Combine coffee and milk.

• What to do: Pour your brewed coffee into your mug, then gently add the heated milk. Start with a 1:1 ratio of coffee to milk and adjust to your preference.
• What “good” looks like: A harmonious blend of coffee and milk, creating a creamy beverage.
• Common mistake: Adding milk to very hot coffee too quickly, which can cause it to curdle slightly. Gently pouring helps.

10. Taste and adjust.

• What to do: Sip your hot milk coffee and adjust the coffee-to-milk ratio or milk temperature as needed. You can also add a touch of sweetener if desired.
• What “good” looks like: A balanced, comforting, and delicious beverage tailored to your liking.
• Common mistake: Not tasting and adjusting, leading to a beverage that isn’t quite right for your palate.

Decision rules (simple if/then)

• If your coffee tastes bitter, then try a coarser grind or a slightly lower brewing water temperature because bitterness often indicates over-extraction.
• If your coffee tastes sour or weak, then try a finer grind or a slightly higher brewing water temperature because sourness can indicate under-extraction.
• If you notice a papery taste, then ensure you are rinsing your paper filters thoroughly with hot water before brewing.
• If your milk develops a skin or tastes burnt, then you have likely overheated it; heat it more gently in the future.
• If you want a stronger coffee flavor to stand up to the milk, then increase your coffee-to-water ratio slightly (e.g., from 1:17 to 1:15).
• If the hot milk coffee is too strong for your liking, then increase the amount of milk or decrease the amount of coffee grounds used.
• If you are using a French press and get too much sediment, then try a slightly coarser grind and ensure the plunger is pressed down slowly and steadily.
• If your coffee tastes dull, then ensure you are using freshly roasted beans and grinding them just before brewing.
• If your hot milk coffee tastes too watery, then you may need to brew your coffee stronger or use less milk.
• If you prefer a sweeter beverage without adding sugar, then try using a milk with a natural sweetness like whole milk or oat milk.
