Introduction:Flat White and Flat White (also known as Flat White or Flat White) are actually the same Australian-originated drink — the Flat White. Like lattes and Dirty Coffees, it belongs to the milk coffee category, but due to differences in ratios and preparation methods, it offers a distinctly unique flavor experience. This article delves into the differences among the three, from espresso extraction ratios and milk foam thickness to coffee bean selection, and also provides practical ordering advice and flavor descriptions to help readers grasp the essence of this classic coffee.
Flat White and Flat White are actually the same coffee beverage — the Flat White, originating from Australia and primarily composed of espresso and milk. Although they use milk and espresso just like lattes and Dirty Coffees, their ratios and preparation methods differ greatly, resulting in distinctive flavor profiles. This article will break down the differences among these three coffees in detail, with a particular focus on the espresso extraction techniques for Flat White, including the proportions and key points of extraction for regular Espresso and concentrated Ristretto, and also includes practical ordering tips and milk steaming suggestions.
Many consumers commonly see “Flat White” and “Flat White” at Starbucks or chain coffee shops, which actually refer to the same Australian-originated Flat White, mainly consisting of espresso plus milk. As a result, most cafés simply call it “Flat White.” But customers might wonder, aren’t lattes and Dirty Coffees also milk-based coffees? In fact, although all three are based on milk and espresso, their ratios and preparation methods vary significantly, leading to very different flavor experiences.
The typical ratio for a latte is about one-third espresso and two-thirds milk. A hot latte usually has about 1 cm of milk foam on top, giving a smooth and velvety mouthfeel, with the aroma and texture of the milk being more prominent. In contrast, the ratio for a Flat White is usually two-thirds espresso mixed with one-third milk, with milk foam that’s only about 0.5 cm thick. Another method uses half higher-concentration Ristretto (concentrated espresso) and half milk, topped with 0.5 cm of foam. This combination usually results in the Flat White being served hot, with the coffee’s flavors being more pronounced and layered.
Dirty Coffee is completely different. It involves pouring two-thirds of cold milk directly over one-third of espresso, and it is only available as a cold drink. The hallmark of a Dirty is that the coffee and milk are not stirred, creating a distinct layered effect. When drinking, there’s no need to stir, allowing the consumer to transition from the boldness of the espresso to the subtle sweetness of the cold milk, experiencing a unique shift in layers.
When making espresso-based milk coffee, choosing the right coffee beans is crucial. A common practice is to use blended coffee beans to extract espresso, as roasters can formulate a blend based on the characteristics of beans from different origins, adjusting the ratio to suit high-pressure extraction. The advantage of blends is that they can effectively reduce flavor defects or instability that may arise from single-origin beans (single-origin beans) under conditions of very fine grinding and high-pressure extraction, ensuring consistent quality and flavor in every shot of espresso. Additionally, blends often offer better cost efficiency, which is more favorable for a café’s pricing strategy. Common blending strategies include medium-to-dark roasts to balance acidity and body, suiting the needs of various types of cafés.
Currently, there are two mainstream methods for making Flat White: one uses a double shot of espresso, and the other uses a double shot of Ristretto. Both types of espresso involve grinding coffee beans into extremely fine particles, tamping them into the portafilter basket of an espresso machine, and extracting under high pressure to obtain a highly concentrated coffee liquid. The main difference between Ristretto and regular espresso lies in the smaller extraction ratio. For example, when a coffee shop makes a double shot of espresso, it typically uses 20 grams of finely ground coffee beans, extracting 40 grams of coffee liquid at a 1:2 coffee-to-water ratio, with the entire process taking about 25 to 30 seconds.
In contrast, the coffee-to-water ratio for Ristretto is approximately 1:1.6, resulting in a more concentrated coffee liquid with a more focused flavor. It’s important to note that this “concentration” doesn’t necessarily mean the flavor is more intense, but rather that the tastes of acidity, sweetness, and bitterness are more condensed. If over-extracted, it can easily produce sharp acidity or burnt bitterness. Therefore, when making Ristretto, it’s necessary to flexibly adjust the amount of coffee and extraction time according to the beans’ characteristics to achieve the best balance.
In actual Flat White preparation, a professional approach is to use the “Sunflower Sunshine Blend” to make a double Ristretto. Taking a 200 ml cup as an example, first pour in the double Ristretto (about 35 grams of coffee liquid), then inject the steamed hot milk, textured to a thin layer, from the center. This creates a gradient-style flavor experience: the first sip highlights the fermented wine-like aroma of the espresso itself, followed by a soft, sweet sensation similar to strawberry milkshake as the coffee and milk blend, and finally a roasted nut aftertaste brought out by the small amount of coffee and milk fusion. The overall profile is rich in layers and smooth on the palate.
