How to Make Whipped Coffee That Requires '400' Hand Whisks?

While browsing the internet, FrontStreet Coffee came across a charming observation: in lockdown, Dutch people play electronic music at home, Italians perform on their balconies to cultivate their artistic sensibilities, and Koreans all make hand-whisked coffee. That brought to mind Dalgona coffee, which went globally viral during the pandemic.

It all started when the drink appeared on a South Korean variety show called "Pyeonstorang" (Convenience Store Restaurant). Its simple preparation sent Koreans confined at home imitating it one after another, determined to try this coffee that requires hundreds of whisks. That led to the scene described above — the whole of Korea became obsessed with making it. At one point many people mistakenly believed the drink was a Korean invention, when in fact it originated at Hon Kee Tea Cafe in the Macau Special Administrative Region of China.

Hon Kee Tea Cafe sits in an old shipyard area of Macau and was already well known years ago. What makes it distinctive is the owner's habit of building a specific coffee foam entirely by hand. The ingredients are ordinary instant coffee powder, mixed with hot water and sugar in a 1:1:1 ratio, then whisked continuously at high speed with a small spoon. As the number of strokes climbs, the liquid coffee expands and its fluidity drops. After about 400 whisks, you have a cup of extremely dense whipped coffee.

The Science Behind It

It makes perfect sense, really — this part of the world has a long love of handcrafted food, from Chaoshan hand-whipped beef balls to Cantonese hand-whipped lemon tea, so hand-whipped coffee in Macau fits right in. Coffee turns from liquid into "foam" because compounds in instant coffee can bind with sugar, and whisking injects tiny air bubbles that build a cotton-like, dense froth. The principle is the same as frothing milk, which means the method also works with espresso and with mocha. In other words, all of these can serve as materials for "400-whip coffee."

How to Make It at Home

As Koreans shared the drink more and more on Instagram, people elsewhere caught on too, though the methods differ somewhat. So how do you make a cup of hand-whipped 400-stroke coffee?

Preparation

Since most of us now work with freshly ground coffee, we'll use espresso as the base. Besides the usual coffee, you'll need sugar (or any flavored sugar) and an electric milk frother — though anyone with strong arms can do it by hand.

FrontStreet Coffee starts with 20g of coffee beans to extract 40ml of espresso.

Then pour the espresso and 10g of sugar into a cup together — that is already quite sweet, so adjust to taste.

Then bring out the electric milk frother and whip.

(FrontStreet Coffee owns a frother but wanted to try authentic hand-whisking. There is a good saying for this: you may not want to whip it yourself, but you can have a friend do it. So a lucky friend was recruited for the job.) When the coffee turns from liquid into a smooth, fine, shape-holding "cream," it is ready.

Leave it at the bottom of the cup and pour in 200ml of milk.

Done. The friend who did the whipping can rest now, and the tasting will be handled by FrontStreet Coffee itself.

Stir the milk and the coffee foam together with a spoon — otherwise the foam alone is very sweet. The result drinks like a silky, rich, sweet latte, and it is genuinely easy to make at home whenever you have a little free time.

FrontStreet Coffee Recommendation

Because whipped coffee leans so heavily on sweetness and body, a Brazil bean is a natural base. FrontStreet Brazil Cerrado Red Bourbon comes from the well-known Cerrado region and is a friendly everyday single origin — soft fruit acidity, good sweetness, and a rounded, delicate body, with the cream, peanut, and cocoa notes typical of Brazilian coffee. It gives the base a smooth, mellow character that plays well with milk and sugar.

For a little more depth in the base, FrontStreet Brazil Queen Estate is worth the step up. Grown at a higher altitude and made from the less common yellow bourbon, it brings a layered nut profile of butter, seeds, macadamia, and almond, plus a fresh sugarcane sweetness. The texture is thick and smooth, whether you drink it on its own or blend it into a milk drink.
