Introduction:Wondering how Flat White differs from latte, and why the former has a stronger coffee flavor and thinner milk foam? This article delves into the origins of Flat White, its key differences from latte and cappuccino, and details the professional barista-recommended recipe ratios and brewing parameters to help you understand the characteristics and brewing tips of this classic southern hemisphere milk coffee from a professional perspective.
Many coffee enthusiasts first encountered Flat White (Fulrui Bai) after Starbucks officially added it to its menu in 2015. Since then, various translated names have emerged, including Costa’s Chengyi Bai and Luckin’s Aorui Bai. In fact, this globally popular milk coffee originated in Australia and New Zealand, and is widely loved for its prominent coffee flavor and delicate milk foam. So, what exactly is the difference between Flat White, latte, and cappuccino? Why does it taste more intense and have thinner milk foam? We’ll take you through a comprehensive understanding, from historical background and recipe ratios to professional techniques.
The Origins of Flat White: Coffee Preferences in the Southern Hemisphere
The name Flat White first became popular in Australia and New Zealand, essentially referring to what locals call “milk coffee.” In the 1980s, as Italian immigrants brought espresso culture to the southern hemisphere, local consumers gradually developed a preference for a form of coffee with a more pronounced coffee flavor and thinner milk foam. The English word “Flat” means “flat,” and “White” refers to the addition of milk, symbolizing the smooth and delicate milk foam surface and its close integration with the espresso.
Unlike Italian or American styles, Australians prefer smaller serving sizes with a stronger coffee flavor, leading to the gradual formation of Flat White, which soon spread to European and American markets and became a staple in many specialty coffee shops.
Flat White vs Latte: Differences in Milk Foam Thickness and Coffee Body
Flat White and latte may seem similar, both being based on espresso with hot milk and milk foam added, but they actually differ significantly in ratio and taste. A typical latte uses a larger serving size, commonly around 300 milliliters, with a relatively lower coffee proportion and milk making up the majority, and the milk foam layer is about 0.5 centimeters, resulting in an overall smoother taste and greater satiety.
In contrast, Flat White opts for a smaller serving size, usually between 150 and 180 milliliters, with a higher proportion of coffee liquid and the milk foam controlled at0.3 centimeters or less, extremely fine and close to the liquid surface, delivering a more concentrated coffee flavor with milk playing a supporting role. Additionally, the milk foam in Flat White is denser and smoother on the palate, with almost no noticeable foam layering.
Comparison with Cappuccino: Differences in Milk Foam and Structure
Cappuccino is known for its thick milk foam, typically reaching 1 to 2 centimeters in depth, presenting a “hamburger-like” structure that often requires sipping the top foam first. In contrast, Flat White’s milk foam adheres more closely to the liquid, offering a simpler and more refined visual and taste experience. This also makes Flat White an ideal vehicle for showcasing the intrinsic flavors of the coffee beans in the trend of specialty coffee.
Professional Recipe: How to Brew an Authentic Flat White?
In specialty coffee shops, the preparation of Flat White typically emphasizes small serving size, finely extracted espresso base, and extremely thin milk foam. Many baristas choose to use a double Ristretto as the base, i.e., extracting the first and middle parts of the espresso, to achieve higher concentration and a more focused flavor profile.
For example, using 20 grams of coffee grounds, approximately 30 grams of coffee liquid can be extracted, with the time controlled between22 to 24 seconds. This extraction method preserves more acidity and aroma, making the overall taste brighter. However, the characteristics of each coffee bean vary, so actual extraction parameters should be adjusted daily based on bean variety, roast level, and grind size.
For the milk foam, it is recommended to use about 150 milliliters of milk, controlling the air intake during frothing to make the foam finer and the thickness lower, with the temperature maintained between55 to 60°Cto ensure the optimal drinking temperature and smoothness. Finally, slowly pour the milk foam into the coffee liquid; due to the extremely thin foam, the overall appearance will have a relatively flat visual effect.
Tip: Avoid Common Mistakes
Common mistakes beginners make when making Flat White include having too thick milk foam, too low coffee proportion, or using too large a serving size that dilutes the flavor. It is recommended to start with a small serving size, focus on the balance between coffee and milk, and strictly control the milk foam thickness to showcase the delicate and balanced characteristics of Flat White.
Conclusion: A Delicately Balanced Coffee Experience
The reason Flat White is so popular lies in its perfect balance of intense coffee and smooth milk. Whether you’re a coffee novice or an advanced enthusiast, understanding its origins, recipe, and brewing details will help you better appreciate this classic coffee beverage originating from the southern hemisphere.
