The Coffee Bean & Tea Leaf Introduces Protein Lattes, Mexican Chocolate Drinks for Winter

Los Angeles, Calif. — The Coffee Bean & Tea Leaf is rolling out a new winter menu centered on functional beverages and seasonal flavors, introducing its first-ever Protein Lattes alongside a lineup of Mexican Chocolate drinks.

The limited-time menu launches nationwide on January 7 and runs through March 17, 2026, according to the company, with early access available now for loyalty app users.

The seasonal offering spans two distinct beverage collections. The Protein Latte line targets consumers seeking added nutrition, with each regular-size drink delivering at least 20 grams of protein.

The Mexican Chocolate beverages focus on comfort-driven flavors, combining dark chocolate with cinnamon-inspired spice. Both collections will be available at participating cafés and through The Coffee Bean & Tea Leaf mobile app while supplies last.

Protein lattes bring functional focus to espresso drinks

The Protein Latte collection marks the brand’s first entry into protein-enhanced espresso beverages, reflecting broader interest in functional coffee formats tied to wellness routines.

According to The Coffee Bean & Tea Leaf, the drinks are designed to fit into morning routines, post-workout occasions, or midday consumption. Customers also have the option to request a lower-sugar version. The lineup includes:

• Vanilla Protein Latte (hot or iced)
• Caramel Protein Latte (hot or iced)
• Hazelnut Protein Latte (hot or iced)

Each drink combines espresso, milk, and added protein, positioning the chain closer to competitors that have expanded beyond traditional indulgence-driven coffee menus.

Mexican chocolate beverages lean into seasonal comfort

Alongside the functional beverages, The Coffee Bean & Tea Leaf is also introducing Mexican Chocolate drinks aimed at winter indulgence. The drinks blend espresso, cocoa, and cinnamon notes, a flavor profile commonly associated with colder-weather menus.

The Mexican Chocolate lineup includes:

• Mexican Chocolate Hot Latte
• Mexican Chocolate Iced Latte
• Mexican Chocolate Ice Blended® drink

The company described the collection as an invitation for customers to slow down and lean into comfort-focused seasonal flavors during the winter months.

App-based promotions anchor winter strategy

The winter menu rollout is supported by a slate of app-driven promotions tied to specific dates and events. According to the company, these include:

• Wellness Wednesday on January 7, 14, 21, and 28, offering a $5 large beverage from 12 p.m. to 6 p.m.
• Super Bowl promotion from February 2–8, offering four beverages for $20
• Valentine’s Day deal from February 13–15, offering two beverages for $10
• Ongoing loyalty perks for rewards members from January 7 through March 17

The promotions reinforce the company’s continued emphasis on mobile ordering, loyalty engagement, and app-exclusive incentives.

Why it matters

The Coffee Bean & Tea Leaf’s winter menu reflects two converging CPG and foodservice trends: functional beverages and seasonal flavor storytelling. Protein-enhanced drinks have moved beyond smoothies and ready-to-drink formats. They are increasingly appearing on café menus as brands look to capture health-conscious consumers without abandoning core espresso offerings.

At the same time, the Mexican Chocolate lineup underscores how chains continue to rely on heritage-inspired flavors to drive emotional connection during peak seasonal windows. These flavors are often used to reinforce familiarity and seasonal comfort.

Together, the strategy highlights how coffee brands are striking a balance between wellness positioning and comfort-driven indulgence. Loyalty apps and limited-time promotions also play a key role in sustaining traffic in a competitive café landscape.

The trend of fortifying menu items with protein is quickly becoming the standard for January 2026. While Coffee Bean & Tea Leaf is tackling the morning caffeine routine, other fast-casual heavyweights are transforming their entire menu strategy to capture the fitness demographic. We just covered the launch of the Playa Bowls “Protein Wave”, a new dedicated lineup of high-protein bowls and smoothies that challenges the idea that superfruit shops are just for sugar-heavy treats.

The trend toward functional and comfort-driven beverages is not limited to traditional cafés. Just days later, Dutch Bros Coffee introduced a new lineup of breakfast-inspired drinks nationwide, translating familiar morning flavors like maple waffles, banana bread, and strawberries into customizable, all-day beverages. The launch reinforces how beverage chains are using nostalgia and flexible formats (including optional protein and energy-based variations) to extend consumption beyond the morning rush and maintain momentum during the early-year reset.

Editor’s note: Source86 perspective

For beverage manufacturers, ingredient suppliers, and private label partners, The Coffee Bean & Tea Leaf’s winter launch highlights a broader shift in café strategy. Brands are expanding beyond traditional coffee into functional formulations. Seasonal innovation is increasingly central to these menu updates. Protein fortification, flavor differentiation, and limited-time menus all require careful sourcing, formulation consistency, and operational readiness.

At Source86, we support food and beverage brands with ingredient sourcing, R&D collaboration, FSQA oversight, and private label and co-manufacturing solutions, helping ensure that functional and seasonal launches scale smoothly from concept to café. As consumer expectations continue to evolve, supply chains must be just as agile as the menus they support. Let’s talk.
