49% of Americans are trying to drink less. Not because they have a problem.
Because there's nothing good to drink instead.

Until now.

Same evening. Different growler.

A 32-ounce growler is a full evening. You're full. You're satisfied. Beer never entered the picture.

How it works.

01

Local brewers make the kombucha

Boulder producers like Upstart, Mortal, and Rev brew in licensed facilities. They fill kegs. We pick them up.

02

Kegs go to member garages

Your neighbor has a kegerator in their garage. Cold, clean, on tap. The keg shows up every week from the co-op delivery route.

03

You walk over with your growler

32oz glass growler. Fill it up. $5. Walk home. That's your evening sorted. Bring it back empty next time.

04

The cooperative owns the network

No franchise. No corporation. The members own the taps, the routes, the relationships. 3% of every pour builds your cooperative equity.

Why it's half the price.

We removed everything that makes kombucha expensive. What's left is the kombucha.

Starting in Boulder, CO.

This is a small thing. One neighborhood. One keg. Ten neighbors who walk instead of drive and fill instead of throw away. If that works, we do it again in the next neighborhood. That's the whole plan.

A co-op.care Health Program

Rid the world of single use.

Single-use bottles. Single-use cans. Single-use relationships that end when the transaction does.

Fill Forward is a co-op.care initiative — a cooperative where your kombucha tap, your growler, and your neighbor are all part of the same network. You own it. You fill it. You pass it forward.
