What is the principle behind milk-washed coffee? How to make a clarified latte with milk and espresso, plus the method and recipe ratios

When most people think of a combination of milk and espresso, the first things that come to mind are classic milk coffees with milk foam, such as lattes and cappuccinos. But the same ingredients, processed with a different method, can take on a completely different appearance and texture. This article introduces a technique called "milk washing"—using the principle that casein coagulates when milk meets acid to remove the fat and protein particles from milk, leaving behind a transparent whey liquid. This time, Front Street Coffee's approach differs from the usual one: during the clarification process, espresso is added directly, so that the entire drink is clarified together, resulting in a "special latte" that looks similar to pour-over coffee but has rich, layered flavors. The article will explain in detail the required materials, recipe ratios, and step-by-step instructions, making it a useful reference for enthusiasts who want to try making specialty coffee at home.

Espresso Special Milk-Washed Latte Making Guide: Ingredient Ratios, Step-by-Step Details, and Practical Recipe

Milk washing is a process that involves mixing an acidic ingredient with milk to curdle the casein, then filtering out a transparent milk serum. Thanks to its striking visual presentation and unique mouthfeel, it is used by many coffee shops in the making of specialty coffee drinks.
