It All Started With A Cup of Coffee...

For us, coffee is more than just an energizing kick; it's a lifestyle of connection.

Tannin was born from a daily coffee walk between friends & roommates, Joe & Henry. Bonded by our love for coffee, we grew increasingly frustrated by funky-feeling mouths, yellowing teeth, and canker sores.

We set out on a journey to discover how coffee and oral health might thrive together. The result is Tannin - the original post-coffee mouth rinse. But beyond our product is the confidence and connection we hope to inspire through it.

Like the coffee that inspired Tannin, community lies at the heart of everything we do. From our Brewville community, that includes each of you, to the communities we seek to support and inspire. We believe we're all better when we spent time together.
