Latte Coffee to Milk Ratio: How to Make Perfect Latte Coffee with Step-by-Step Instructions

Latte is one of the most common coffee beverages, made by combining espresso with a large amount of milk, which significantly masks the bitterness of coffee. Even if you don't typically enjoy coffee, it's hard to resist a well-made latte.

Although a latte might seem like a simple combination of coffee and milk, creating a delicious one requires specific techniques and attention to detail.

A. Extracting Espresso

The quality of your espresso directly impacts the flavor of your latte. For instance, if your espresso has a burnt or bitter taste, adding milk will struggle to mask these unpleasant flavors. Under-extraction will result in a sour and tasteless latte. When extracting espresso, you should establish a proper extraction plan and execute it consistently. (Note: In some cases, the standard 1:2 coffee-to-liquid ratio with 20-30 seconds extraction time may not be suitable for making latte espresso; adjustments should be made based on specific conditions.)

B. Milk Ratio

There is no fixed ratio for how much milk to add to a latte. Typically, for a standard latte, the ratio of espresso to milk ranges from 1:5 to 1:8. The main factors affecting this ratio are flavor expression and the characteristics of the espresso.

If you prefer a milder coffee flavor, you can add more milk to mask more of the coffee taste. Conversely, if you enjoy a richer coffee flavor, use less milk to make the coffee more prominent. This adjustment is based on personal taste preferences.

The characteristics of the espresso also play a crucial role. Some espresso made from certain coffee beans has an intense bitter profile, which benefits from adding more milk to balance the flavor. Other espresso may have a lighter, more delicate character, where adding too much milk would overpower the coffee taste, turning your drink into what might be called "milk with coffee" rather than a proper latte. Therefore, to balance coffee and milk flavors, you may need to use less milk in such cases.

FrontStreet Coffee's lattes use espresso made from their "Warm Sun Blend" as the base. This blend has a flavor profile that isn't overly bitter, and when made with a 1:6 milk ratio, the coffee flavor remains present without being overpowered by milk, while the bitterness isn't too prominent. However, this 1:6 ratio is specific to FrontStreet Coffee's approach. If you're using this as a reference, it's best to focus on taste rather than fixed numbers.

C. Fine and Thin Milk Foam

A latte with proper milk foam offers an enhanced mouthfeel and texture. The key is that the foam must be sufficiently fine. The standard for checking quality is that the surface of properly frothed milk should have no large bubbles, appearing so fine that it reflects light like a mirror.

The foam shouldn't be too thick either, or you'll end up with something closer to a cappuccino. For a standard latte in a regular-sized coffee cup, the foam thickness should be around 0.5cm.

D. Milk and Coffee Integration

Can you simply pour frothed milk directly into coffee? This approach will likely result in uneven flavors—alternating sips of strong coffee then milky sweetness—which creates an inconsistent drinking experience.

A well-integrated latte shows uniform fusion between the milk foam and coffee crema, presenting a consistent "golden brown" color with a smooth, fine surface. Poorly integrated lattes display uneven "golden rings" and deliver inconsistent flavors with each sip.

For better integration, the general technique involves stirring in one direction. Hold the coffee cup with your left hand and the milk pitcher with your right hand, positioning them slightly offset from each other while making circular motions. This stirring technique, with one hand slightly higher than the other, easily achieves thorough mixing of coffee and milk. However, it's not recommended to pour from too high—generally no more than 7 centimeters above the liquid surface—to avoid creating large air bubbles.
