Buenos Aires' Coffee Artists and Their Latte Craft

In Buenos Aires, coffee isn’t just a drink—it’s a daily ritual, a social anchor, and for some, a canvas. The city boasts over 3,000 cafés, many with century-old roots, where locals linger for hours. But beyond the historic charm and strong espresso, a new generation of baristas is transforming the experience, turning each cup into a small masterpiece. Among them is Rafa Sosa, whose latte art captures both technique and emotion.

Buenos Aires has over 3,000 cafés, including nearly 70 with histories spanning a century. At the heart of the modern scene is 27-year-old Rafa Sosa, who crafts intricate latte art—including his signature swan—using steamed milk at around 70°C and expert microfoam control. He says great coffee starts with quality beans and the right milk ratio, and that latte art should forge a personal connection with the drinker.

The Café Culture of Buenos Aires

Buenos Aires is a city steeped in coffee tradition, shaped by waves of European immigrants, especially Italians and Spaniards, who arrived in large numbers during the early 20th century. They brought with them their coffee habits, leading to the proliferation of cafés across the city. Today, more than 3,000 cafés operate in Buenos Aires, with nearly 70 of them boasting histories of 100 years or more. Many still practice traditional methods like hand grinding and brewing, preserving the city’s rich café heritage.

All About Rafa Sosa, the Latte Artist

Rafa Sosa, 27, is the head barista at the compact yet renowned Café Todos los Santos, located in the Belgrano district. Though he’s been in the industry for just three years, Sosa has spent two of them training at the café, mastering the nuances of various coffee beans and their roast profiles. His signature drink is a latte adorned with a delicate swan made from steamed milk, which has become a customer favorite. Sosa believes that great latte art begins with a deep understanding of coffee flavor and texture, and that every pour should engage the drinker emotionally.

The Science and Art of Milk and Coffee

According to Sosa, the key elements of a great latte are the quality of the coffee and milk, and the precise balance between them. He uses high-quality coffee beans that produce a full-bodied, evenly extracted shot—describing the ideal crema as having “good stretch.” The milk, meanwhile, must be steamed to around 70°C, with microfoam that’s neither too thick nor too thin. Sosa emphasizes that achieving the perfect pour requires not just technical skill, but also patience, composure, and care. He also noted that milk should be textured to achieve optimal microfoam consistency for detailed latte art.

Designing Latte Art: More Than Just Looks

Sosa often tailors his latte designs to reflect a customer’s mood or personality. While he’s best known for his swan, Sosa explained that latte art typically starts with three basic shapes: the heart, the lotus base, and the tulip. These can be combined into more elaborate figures, such as a swan (lotus base with wings) or even a phoenix. However, many designs are abstract, meant simply to enhance the visual appeal of the drink. For Sosa, the primary goal of latte art is not decoration, but connection—drawing the customer’s attention to the craft behind their cup and creating a moment of shared appreciation.

How to Truly Enjoy Coffee in Buenos Aires

Sosa believes that Argentines, while fond of long café visits, often drink coffee out of habit rather than conscious enjoyment. He encourages both baristas and customers to treat coffee as an experience, not just a routine. Part of that transformation, he argues, comes down to the skill of the barista, who can guide drinkers toward better beans, blends, and ratios. In recent years, more Buenos Aires cafés have begun hiring trained baristas rather than just coffee servers, reflecting a shift toward a more intentional coffee culture.
