Introduction:Flat White (also known as "Australian White" or "Velvet White") is a milk coffee that emphasizes the essence of coffee itself, and is highly favored by consumers who love strong, bold flavors. Compared to a latte, it is characterized by thinner milk foam, a smaller serving size, and double ristretto shots, creating a rich yet balanced taste. However, most cafés do not offer Flat White in iced form, which is closely related to its foam design and extraction philosophy. This article delves into the characteristics of Flat White, how it differs from a latte, practices in both New Zealand and Australia, actual preparation parameters, and explains why this coffee is only suitable for hot servings. It also extends to introduce the flavor contrast with Dirty coffee.

Flat White (Velvet White / Australian White) is considered by many coffee enthusiasts as a classic milk coffee that combines a strong coffee flavor with a delicate layer of milk foam. Originating from New Zealand and Australia, although this beverage shares the same foundation of fresh milk and espresso as a latte, it follows a distinctly different extraction logic and tasting focus.

The charm of Flat White lies in its extremely fine milk foam, with a thickness of only about 0.3～0.5 centimeters . Paired with a small cup size and double ristretto shots, each sip allows you to simultaneously experience the velvety foam and intense coffee liquid. For this reason, most specialty cafés only offer it in hot form to maintain the stability of the foam and the consistency of the taste.

Among the many types of coffee, if you prefer a softer and sweeter profile, a latte would be your first choice; but if you want to more directly experience the layers and aromas of coffee itself, Flat White is superior. Taking a professionally made Flat White as an example, it often exudes a captivating whiskey-like aroma, a soft base of cream and vanilla, along with a refreshing acidity reminiscent of berries, showcasing a very full and three-dimensional coffee flavor.

So, what exactly is the difference between Flat White and a latte? Although both are made with fresh milk and espresso, their preparation philosophies are quite different.

Latte (Caffe Latte), when translated directly from Italian, means "milk coffee", emphasizing the balance between coffee and milk—highlighting both the essence of the coffee and the warmth and sweetness of the milk, giving equal importance to both. In contrast, Flat White puts coffee at the forefront, using milk to complement and enhance the aroma and richness of the coffee, making the overall coffee characteristics more prominent and the flavor more intense.

It is worth noting that there is currently no fully unified standard recipe for Flat White within the industry. Each café adjusts to create their own version based on the coffee beans used, extraction methods, and brand style. Taking the approach of New Zealand baristas as an example, they typically use a smaller cup size than that of a latte, about 150 milliliters, and base it on double ristretto shots. A smaller cup size means relatively less milk, naturally increasing the proportion of coffee, making the drink’s flavor more concentrated and intense. As a result, it is often affectionately nicknamed a “mini latte”.

With the advancement of espresso technology, some Melbourne cafés have taken it a step further by using double ristretto as the base while maintaining a milk foam thickness similar to that of a latte. Ristretto is an extraction method that uses the same amount of coffee grounds but yields a smaller volume of coffee liquid, and can be considered a more concentrated version of espresso. Its flavor focuses more on the fruity acidity and sweetness extracted in the early to mid-stages, resulting in a bolder taste and higher demands on coffee bean quality.

In Australia, baristas tend to maintain a cup size similar to that of a latte, but place emphasis on controlling the thickness of the milk foam. The “Flat” in Flat White means “flat”, indicating that its milk foam layer must be extremely thin, with thickness controlled between 0.3～0.5 centimeters , and it must not rise above the rim of the cup, ensuring that every sip can enjoy both the coffee liquid and the delicate foam. In comparison, a latte’s foam usually rises about 0.5～0.7 centimetersabove the rim, whereas Flat White requires the foam to be level with the liquid surface, presenting a visual and textural trait of “flat white”.

In reality, each café adjusts to create a unique Flat White style based on its own understanding, the characteristics of the coffee beans used, and technical capabilities. For example, one establishment insists on three core elements when making Flat White: small cup size, extremely thin milk foam, and a base of double ristretto shots.

In terms of extraction, one establishment opts for 20 grams of coffee grounds, extracting 30 grams of coffee liquid, over approximately 25～27 seconds. These parameters are fine-tuned daily based on the characteristics of their classic blend. This extraction method fully showcases the aroma and sweet-sour layers of the coffee, serving as the core flavor source of the Flat White.

After completing the espresso extraction, the coffee liquid is poured into a 200-milliliter hot drink cup, followed by steaming 150 milliliters of milk to the appropriate temperature and foam thickness. During steaming, care must be taken to control the air intake, making the foam layer finer and denser, with an ideal temperature of 55～60°Cto ensure a smooth and comfortable mouthfeel. Finally, the steamed milk foam is evenly poured into the coffee liquid without any mandatory latte art, completing a Flat White with distinct layers.

The Flat White from one establishment typically carries aromas of chocolate milk and whiskey truffle chocolate, with a smooth, rich entry and a long-lasting aftertaste, delivering a milk coffee experience that is intense yet balanced.

So, can Flat White be made into an iced drink? The answer is usually no. This is closely related to its foam design and overall drinking logic.

Baristas generally believe that the charm of Flat White lies in experiencing the interaction between the foam and the underlying espresso with every sip. This experience can only be fully realized when the foam remains fine, thin, and warm. Once ice is added, the drink’s temperature drops rapidly, diluting the integration of milk and coffee, and the foam is prone to collapse or layering, disrupting the originally uniform texture.

If you crave a cool milk coffee that still retains a strong coffee flavor, consider trying an iced latte. Alternatively, the recently popular Dirty coffee is also a great option. The hallmark of Dirty lies in pouring hot espresso directly into chilled fresh milk, allowing the coffee to slowly seep down and create a visually “dirty” layered effect, along with a contrasting cold-hot, intense flavor impact—a truly unique taste adventure.
