Most foamers will form hard foam on milk, which is not good for latte or cappuccino. Milk of the right texture is creamy, light, breathable, and never stiff or separate. This is why our current favorite is Subminimal’s Nanofoamer.
As the darling on Kickstarter, Nanofoamer is now a real product. It looks like a very small immersion blender, more or less exactly what it looks like. It has two different screens installed on the blade: one for fine-textured milk and the other for ultra-fine-textured milk.The difference is subtle, but the milk produced by the fine filter is A small amount The air bubbles are larger than the ultra-fine filter.The filter allows Nanofoamer to do what a barista does with a steam wand: it Texture Your milk is the perfect cream top.

Machines that have not finished cutting
Neat K-Latte (90 USD): K-Latte is an admirable and affordable little Keurig with a traditional electric bubbler on it. It can spray concentrated foam like our recommended K-Café, but the foaming agent is no better than the one you can buy separately, and its non-stick coating sometimes requires gentle scrubbing.
De’Longhi Lattissima One ($380): For many years, Nespresso has been installed in my house. Nespresso is not as delicious as freshly brewed coffee in a coffee shop, but it is fast and effective. There are other Nespresso coffee machines with foaming agent, but De’Longhi’s Lattissima One is an elegant small machine with a stable pressure of 19 bar. This used to be one of our choices, but it ended up leaking and there was water everywhere. It is not a bad machine, but based on our experience and other reviews on the Internet, it cannot be maintained for long.
Questions and answers
How do you test each machine?
In order to find the best latte and cappuccino machines, I first researched widely available products and insisted on using models under $800. I tested about a dozen machines with different types of coffee, pods, and milk, each for one to three months (depending on the model). I tried to adapt to each machine to some extent and use them at will, but I also (where possible) tested the same milk and coffee grounds to compare the milk/foam ratio and taste.
Setup and cleaning are especially important, as is durability.The whole point of a device like this is to save time and energy and/or produce higher quality beverages than those without it, so we do not recommend any products that cannot produce delicious espresso with save time.
How do you make latte, cappuccino or macchiato?
Here is a quick way to remember one latté with one Cappuccino: Traditionally, latte is more milk than coffee without froth, while cappuccino, milk and froth are equal. There are many different opinions on the exact ratio, but usually a cappuccino is 2 ounces of double espresso (or 1 ounce of single serving), 2 ounces of steamed milk, and 2 ounces of frothy milk. For a latte, you will usually see a single or double cup of espresso, 6 (ish) ounces of steamed milk, and a bit of foam mixed with the espresso cream when the milk is poured.
This is why latte art is mostly brown (espresso crema) with a little white (micro-foam in milk). Sometimes I use a spoon to hold the foam to the end. This is a good way to make sure your latte does not foam too much. But to be honest, sometimes I just scoop the foam with a spoon afterwards, because the foam is delicious.
