Why It Won Our Review

The main test for any milk frother is how tight and small its foam bubbles are, which is what gives foam its silky consistency. During our testing, the Miroco produced microfoam that was similar in quality to commercial espresso machines. And it was capable of doing so with hot and cold milk.

Aerating milk involves whipping air bubbles into liquid to create a foam, but it’s usually heat that makes foam last: as milk heats up, proteins begin to denature, and the loose amino acid strands around the foam bubbles to give them structure. However, the Miroco created a silky foam texture in cold milk as well using the speed of its whisk, while other models struggled with this task. And with two different-sized whisk attachments, we could control if we wanted a small or large amount of foam, too.

We also appreciated its heating element and auto-shut-off feature, which killed the heat as soon as the milk hit 160ºF. The handle and spout made it easy to pour milk foam into your cup without any drips or spills, while many other milk frothers were just cylinders without an elongated spout, making them awkward (and messy) to pour from.

Good to Know 

  • Normally $47, now $38
  • Comes in black or stainless steel
  • Comes with two different-shaped whisk attachments for different foam amounts
  • Features an auto-shutoff when it hits 160ºF
  • Its one con is that it has an 8-ounce stated capacity, which is only enough for one serving


Does the Miroco milk frother heat the milk?

Some milk frothers only feature a whisk that aerates the milk, but the Miroco Milk Frother includes a heating element that heats the milk to 160ºF while it aerates. You can also use it to aerate cold milk, too, if you’re looking for cold foam.

Can you put other liquids in a milk frother? 

Though they were designed for milk, you can also add plant-based milk, or use it to mix matcha powder or hot chocolate mix into your beverage.
