Walk through any common area at Cal Poly San Luis Obispo, UC San Diego, Claremont McKenna, or Occidental College on a weekday afternoon, and you will likely spot them: the distinctive tall cans of Guayakí (now Yerba Madre), Mateína, or Drink Weird in the hands of students heading to seminar, study session, or gym. What was once a niche import has become — quietly and then suddenly — a defining beverage of American campus culture in the 2020s.
Why Students Are Making the Switch
The appeal of yerba mate to the college demographic is multifactorial. At its core, it offers a caffeine delivery mechanism that students describe as 'smoother' and more sustained than coffee — typically 70–85 mg of caffeine per serving, delivered alongside theobromine and a complex polyphenol matrix that appears to modulate the stimulant experience. In practical terms, students report better focus without the jitter-crash cycle that accompanies high-caffeine espresso drinks or canned energy beverages.
Health consciousness plays a significant role. Generation Z consumers, who represent the majority of current university students, have demonstrated measurably higher preference for beverages with natural ingredients, low sugar content, and functional health claims compared to preceding cohorts. Yerba mate checks these boxes while also offering an antioxidant profile that exceeds green tea — a comparison that features prominently in brand marketing and campus word-of-mouth.
The Brand Strategy That Built a Market
The phenomenon did not emerge spontaneously. Yerba Madre (formerly Guayakí) invested heavily in campus marketing beginning in the late 2010s, including brand ambassador programs, sponsorships of campus events, and strategic placement in university retail outlets. The company's 'Come to Life' branding — emphasizing sustainability, community, and natural energy — resonated with the values-driven purchasing patterns of college-aged consumers. Competitors including Mateína and Drink Weird have since followed similar strategies, expanding the category's campus presence.
Yerba mate has become almost a campus staple. Students who wouldn't touch a Monster or Red Bull are completely comfortable with a can of Guayakí. It's the aesthetic, the values, and the feeling.
A $722 Million Market with Room to Grow
The US yerba mate market was estimated at approximately $722.7 million in 2025, growing at an annual rate of 6.0%, according to Future Market Insights. The campus channel — while not separately quantified — is widely viewed within the industry as a critical pipeline: consumers who adopt yerba mate during their university years tend to maintain the habit into professional adulthood, creating long-term brand loyalty. Athletes have proven particularly receptive, with yerba mate's reputation as a source of 'clean' energy appealing to student-athletes seeking performance support without banned substances.
The cultural dimension adds staying power. Unlike energy drinks, which are consumed primarily for functional effect, yerba mate carries a social ritual dimension — sharing a gourd of traditionally prepared mate is a bonding activity that campus clubs and cultural organizations have actively promoted. At schools with significant Latin American student populations, mate circles have become visible symbols of cultural identity; at others, they serve as points of intercultural curiosity and connection.
