For Chinese, soy milk is one of the most familiar breakfast staples imaginable. No matter where you are, chances are you’ll see soy milk on the menu at a local breakfast shop. When it comes to combining soy milk with coffee, many people might first think of the soy latte once heavily promoted by Starbucks—a well-established and clearly defined drink concept. However, it never truly took off in mainland China.
So if I ask you: where is the combination of soy milk and coffee most popular?
The answer is: Taiwan.
When talking about Taiwanese breakfast culture, soy milk undoubtedly holds a dominant position. Take Fuhang Soy Milk, for example—one of the oldest traditional breakfast shops in Taipei. This style of breakfast can be traced back to 1955, when immigrants from mainland China settled in Yonghe District (in today’s New Taipei City) and brought pastries and breakfast dishes from their hometowns. That’s why you still see so many breakfast shops in Taipei with “Yonghe” in their names.
In traditional soy milk shops, customers can customize their drinks—adding sugar, drinking it hot or iced, or pairing it with fried dough sticks or rice rolls. Soy milk isn’t just a beverage here; it represents a deeply rooted food culture.
Perhaps it’s precisely because of this long-standing habit and flavor preference that something magical happened when soy milk met coffee. Globally, the place where soy milk and coffee have become the most popular, widely accepted, and mainstream combination is undoubtedly Taiwan.
Coffee culture flourished in Taiwan in the late 20th century. Western-style chains and local specialty cafés rapidly expanded across the island. In a region that already had a strong soy milk tradition while simultaneously embracing coffee culture, a creative fusion was almost inevitable. Although there’s no clear record of who first invented soy milk coffee, it was likely experimented with by different people in different places around the same time. The earliest versions were probably quite simple—perhaps just pouring a packet of instant coffee into a cup of soy milk at home.
When soy milk coffee truly became a widely recognized beverage, much of the credit goes to Starbucks. Around 2002–2004, Starbucks introduced the “Soy Latte” to the Taiwanese market. While soy-based lattes had already existed in Western markets as an alternative for vegans and people with lactose intolerance, launching it in Taiwan significantly helped educate consumers and popularize the idea that soy milk and coffee could pair perfectly together. It also standardized the drink’s name and preparation.
With Starbucks paving the way and shaping consumer awareness, many local independent cafés and breakfast shops began to follow. Instead of relying solely on commercial soy milk, some experimented with freshly ground, richer traditional soy milk, adjusting sweetness levels and thickness to better suit local tastes. During this period, soy milk coffee evolved from being merely an international dairy alternative into a distinctly Taiwanese-style beverage with its own local character.
Today, in Taiwan, soy milk coffee can be found almost everywhere—coffee chains, independent cafés, traditional breakfast shops, and even convenience stores. It has become a regular menu item, much like milk tea. It’s not just for coffee enthusiasts; it has seamlessly integrated into everyday breakfast and afternoon tea routines.
In that sense, the birth of soy milk coffee was not a single event, but a gradual process. It is not a traditional Taiwanese coffee in the historical sense, but rather a product of modern Taiwanese beverage culture—an innovative fusion that perfectly reflects Taiwan’s culinary identity: open to diverse influences and always ready to reinvent flavors in creative ways.
