Which type of foam is classified as micro foam?

Milk foam is classified as micro foam due to its fine, velvety texture and stable structure that results from the fine microbubbles created during the steaming process. This type of foam is essential in various coffee beverages, especially for crafting drinks like cappuccinos and lattes. The microfoam is characterized by its microbubbles that create a creamy mouthfeel and allow for better integration with espresso, enhancing both the flavor and visual appeal of the drink. In milk foam, these tiny bubbles create a consistent and luxurious texture, making it ideal for latte art and for providing an enjoyable drinking experience.

Other types of foam, such as sea foam and lace foam, do not achieve the same fine quality or stability as microfoam. Sea foam typically refers to the frothy structure found in ocean water, while lace foam usually relates to other contexts in culinary arts or beverages but does not match the characteristics of microfoam used in bartending or coffee preparation.
