Q&A for How to Make a Latte

Sift a teaspoon of matcha into a cup. Add a bit of hot water and stir until the matcha becomes a smooth paste. Transfer the matcha tea into a cup. Pour steamed milk over matcha tea. Scoop foamy milk on top.

It’s good, but it is not as good as homemade froth. However, it is also completely up to your personal preference.

An Aeropress is similar to a French press, but much faster, making 1 - 3 cups in about a minute and espresso in 30 seconds. It's worked directly into the cup. You can find them on Amazon and elsewhere.

Serve it in a mug (tall and thin or short and wide, either one) and top it with whipped cream.

You can always use less, but most lattes are made with a double shot of espresso. A double espresso wouldn't have as much milk as a latte. There's the difference.

It may just depend on the brand/quality of coffee. Maybe the commercially purchased coffee is better quality - you could try buying that brand's coffee to brew at home, if available. Alternatively, maybe the water you use is impure - be sure to filter tap water before using it for coffee or other drinks. And I assume you're having it the same way at home (with soy milk) - if not, try to do so; plain coffee with nothing added could be too acidic for some people, and lactose intolerance is a factor for others.

A shot of espresso is around 4 ml.
