The Yéyo Story
Yéyo began with an idea in 2009. What followed was a relationship with Arandas, the Vivanco family, and Sergio Cruz that continues to shape every bottle.
Explore the StoryThe founder

Yéyo started with Jon Bullinger in 2009. At 25, Jon left a full-time job at Intel with an idea that was far from fully formed: a tequila built around discovery, experimentation and an unwillingness to simply make what already existed.
That idea brought him to Arandas, Jalisco. There, among red soil, Blue Weber agave and generations of tequila knowledge, he found the place and the people that would become part of Yéyo’s story.
Jon’s path to tequila didn’t begin in the spirits industry. A trip to Mexico led him to a family-run distillery in the Highlands of Jalisco and the Vivanco family and Sergio Cruz. Curiosity became an obsession with the details: agave, fermentation, distillation, flavor and, eventually, barrels.
Yéyo wasn’t created from a single recipe. Hundreds of iterations were crafted, tasted, tested and scored as Jon worked with the team in Arandas to find the character he wanted Yéyo to have. That willingness to keep trying became part of the brand. It still is.
Jon is at the distillery in Arandas roughly 10 times a year. Not for a photo. To work alongside Sergio, the Vivanco family and the distillery team: tasting, reviewing production, discussing agave, working through barrels and looking for ways to improve what comes next.
Different proofs. Unexpected barrels. Single-barrel experiments. Limited releases. The question behind much of it is simple: what happens if?
For Jon, Yéyo has always been about the pursuit
Love. Travel. Family. Experience. Pursuit.
The curiosity that started Yéyo still drives it. The same conversation continues in the Barrel Room: Jon and Sergio keep exploring different woods, previous fills, aging approaches, proofs and blends together. Some experiments become releases. Some simply teach the team what to try next—always looking for directions that take tequila somewhere unexpected without losing what makes it tequila.

Today, Jon and Sergio continue to work side by side on Yéyo, together with the Vivanco family and the team at NOM 1414. Yéyo isn’t a formula handed to a distillery. It’s built through an ongoing collaboration.
Arandas, Jalisco
Friends. Partners. Still experimenting.
From the field to the bottle
Yéyo isn’t made from a recipe that gets handed off and repeated. Jon, Sergio and the team work through the process together, from the agave fields through production, fermentation, distillation, barrels and the final bottle. Every batch gives them another opportunity to learn, adjust and make Yéyo better.
Tequila is agriculture
Agave doesn’t grow in a laboratory. Soil, temperature, weather and growing conditions continue to change, and fermentation and production respond to those conditions too. So making Yéyo isn’t simply a matter of repeating the last batch. It means paying attention. Tasting. Learning. Adjusting. Improving.
The goal isn’t to make the last batch again. It’s to make the next one better.
Jon, Sergio and the team approach every production with the same question: what did we learn last time, and what can we do better this time? The aim is to preserve the character people love about Yéyo while continuing to refine it.

Built over time.
Jon first built relationships with Sergio Cruz and Sergio Vivanco in 2010. Since then, he’s returned to Arandas year after year to work alongside them, learn, experiment, and spend time together. More than 15 years later, they’re not just people Yéyo works with. They’re friends.
Founder & Master Distiller

Master Distiller and part owner of Yéyo. Part chemist, part artist, Sergio Cruz spent more than a year working with Jon to develop Yéyo’s cooking methods and flavor profile. He lives and works in Arandas, where he guides Yéyo’s fermentation and distillation at NOM 1414.
Jon brings the questions. Sergio and the team in Arandas turn them into tequila.
