FAQ
1. What is the ideal ratio of espresso to milk in a latte?
The traditional latte ratio is approximately 1:3 or 1:4 espresso to steamed milk, meaning one shot of espresso (about 30ml) combined with 90-120ml of steamed milk. This ratio can be adjusted based on personal preference or size variations, but maintaining this proportion ensures the coffee flavor remains present while being complemented by the creamy milk texture.
2. What temperature should milk be heated to when steaming for lattes?
Milk should be heated to 140-150°F (60-65°C) for optimal taste and texture. Heating beyond 160°F (71°C) will scald the milk, creating an unpleasant burnt flavor and breaking down the proteins that create smooth microfoam. Using a thermometer during initial learning helps develop the ability to judge temperature by touch and sound.
3. Can I make lattes without an espresso machine?
While traditional lattes require espresso as the base, you can create latte-style drinks using strong coffee from methods like French press, moka pot, or concentrated cold brew. For milk steaming without a steam wand, use a French press plunger to froth heated milk, or try heating milk in a saucepan while whisking vigorously to create foam.
4. How do I fix bitter-tasting lattes?
Bitter lattes typically result from over-extracted espresso. Try adjusting your grind to be slightly coarser, reducing extraction time, or checking that your coffee beans aren't over-roasted or stale. Also ensure your espresso machine's brewing temperature isn't too high, as temperatures above 200°F can contribute to bitter extraction.
5. What's the difference between a latte and a cappuccino?
The main difference lies in milk texture and ratios. Lattes contain more steamed milk with minimal foam (microfoam), creating a creamy, smooth texture with a subtle coffee flavor. Cappuccinos have equal parts espresso, steamed milk, and thick foam, resulting in a stronger coffee taste and lighter, airier texture. Cappuccinos are also typically served in smaller cups (5-6 oz) compared to lattes (8-12 oz).
