Siete Foods adds sourdough-style tortillas, extending fermentation beyond bread

Sourdough has left the bakery aisle and landed in tortillas. Siete Foods is rolling out Gluten Free Sourdough Style Tortillas alongside Maíz Organic Yellow Corn Tortillas, turning a bread-world flavor cue into a packaged-food pitch built around softness, tang and cleaner-label claims.

The sourdough-style tortillas are described as heritage-inspired and “made in the spirit of gathering,” with a flour-like texture and mild tang. That is a very different promise from traditional long-fermented sourdough, where time, wild culture and fermentation do the heavy lifting for structure and flavor. Here, the sourdough idea reads more like a sensory signal than a bread-baker’s fermentation project: the aim is not a blistered crust or a dramatic rise, but a soft tortilla with a familiar sour note.

Siete’s Maíz tortillas take a different route. The company says they are “rooted in heritage” and made with organic corn, sea salt and a touch of organic olive oil. Both new products are gluten-free, vegan and non-GMO, and the Maíz tortillas also carry USDA organic positioning. The Maíz pack is sold in 12-count bundles for a manufacturer’s suggested retail price of $4.99, while the sourdough-style tortillas come in 10-count packs at $6.99.

Andrés Figueroa, Siete’s vice president of innovation, framed the launch as more than a flavor exercise, saying tortillas are a symbol of connection, culture and gathering. That matters because Siete has built its identity around Mexican-American family roots, and the brand says it was founded in 2014. PepsiCo completed its $1.2 billion acquisition of Siete Foods on January 17, 2025, after announcing the deal in October 2024, making this tortilla launch part of a much larger consumer-products machine.

The products rolled out to retailers nationwide in late April, including Whole Foods Market, Target and Sprouts. Siete is also tying the launch to a 2026 taco truck tour with stops in Austin, Phoenix, Los Angeles, San Francisco and Denver, where it says it will serve free tacos featuring the new tortillas.

For home bakers, the takeaway is straightforward: “sourdough-style” in packaged tortillas is innovation in flavor marketing, not a substitute for a properly fermented loaf. The label still signals something useful, though, because it tells you exactly what the brand is chasing: soft texture, mild tang and the cultural cachet of sourdough, packaged for the tortilla shelf.
