How Blend Coffee Fits Flat White vs Latte: Milk Foam, Size and Espresso Ratio
A flat white uses the same espresso base as a latte but with less milk and a thinner layer of steamed milk foam, which keeps the coffee flavor forward. The drink rose in the 1980s in Australia and New Zealand, where drinkers wanted a creamy texture without letting milk crowd out the espresso, so the serving size stays smaller.
Australia and New Zealand developed separate approaches, one built on a double ristretto with steamed fresh milk, the other on a single espresso with thin foam. Shops pick a blend coffee to match the flavor they want. On milk foam and ratio, the national coffee association cappuccino latte difference milk foam espresso comparison still holds: cappuccino has the thickest foam, latte the most milk.
It's also espresso plus milk, so why is a flat white always a size smaller than a latte? Behind this lies the original intent of the flat white—to make the coffee flavor more prominent, with milk only as a supporting act. From the perspective of Front Street Coffee, this article sorts out the background of the flat white's rise in the 1980s, the respective approaches to making it in Australia and New Zealand, compares its specific differences from a latte and a cappuccino in milk foam thickness and milk ratio, and includes the parameters used at Front Street's shops plus buying suggestions for five espresso blend beans, helping coffee lovers recreate a rich, smooth flat white at home.

Whether large or small, whether diluted with water or with milk added, common drinks like americano, latte, flat white, and cappuccino are all built on espresso. Espresso itself is extremely versatile: swap one accompaniment or adjust the ratio, and it transforms into another popular coffee. Today's topic, the flat white, evolved precisely by subtracting from the hot latte, and later rose to become a hot pick among espresso drinks.
How did the Flat white come about?
When it comes to the flat white's origins, Australia and New Zealand each have their own account, both claiming to be the birthplace. Although the origin can't be settled, one thing is certain: the flat white emerged from Australians' higher demands for coffee flavor. In the 1980s, the flat white began to gain popularity. At the time, people wanted higher-quality coffee but didn't want too much milk crowding the cup; they hoped to still feel the strong character of espresso while getting a creamy smoothness on the palate, which placed demands on milk steaming. The flat white satisfied exactly these needs and gradually became an underpinning of coffee culture in both Australia and New Zealand.
According to the flat white's characteristics, Australia and New Zealand each developed different presentations, forming two approaches. One uses a double ristretto as the base, combined with steamed fresh milk, highlighting a rich milk-coffee texture; the other blends a single espresso with thin milk foam into the drink.
How exactly to make it depends on the coffee beans a shop uses and the flavor it wants to express. The flat white served at Front Street's shops uses its own roasted "Sunflower Warm Sun Blend," which is fresh in style and soft on the palate, so the base is a double ristretto.
What's the difference between a flat white and a latte?
The most intuitive way to identify a flat white is that thin, glossy layer of milk foam. The "Flat" in flat white means flat: a finished flat white's surface must be thin enough to sit level with the rim of the cup, with the foam not domed, so that every sip of strong coffee carries a silky layer of foam.
Among the three common hot milk coffees, cappuccino has the thickest foam, usually 1–2cm; flat white has the thinnest, generally only 0.3–0.5cm; latte foam is mostly 0.5–0.7cm and forms a little dome, whereas a flat white must stay under 0.5cm, otherwise it can't be called a "flat" surface. Foam thickness varies by shop; some baristas, to let guests experience the upper layer of coffee crema to the fullest, skip steaming foam altogether and simply pour heated milk into the espresso. Front Street wants guests to drink a flat white that is dense and smooth, so it keeps a 0.3cm layer of foam.
For a flat white that pursues a rich mouthfeel, the amount of milk is less than in a latte, and exactly how much to add likewise depends on the cup size a shop serves. Imagine if you made it with a latte's milk ratio—it would drink more like coffee-flavored milk. For example, the ceramic cup Front Street's shops use for a flat white is 180ml; the base is two ristrettos totaling 30g, and 150g of hot milk must be added to present a richer, fuller flavor.
