A Message from Doc
For more than 20 years, Wine To Water has given clean water to millions of people in some of the toughest places on earth. Back then, people called us cowboys because we didn’t do things the “normal” way. We went where others wouldn’t. We cut through the red tape. We broke the rules if that’s what it took to get clean water in someone’s hands.
The DROP Filter is born out of that same grit. It’s built on the same tech we’ve carried into disasters and remote villages for over a decade — the kind of places where failure isn’t an option.
This isn’t just a filter. It’s a reminder of who we are: bold, relentless, and built to go beyond the last mile. It’s about changing the world, one wild adventure at a time.
Thanks for riding with us.
