About OpenBrew

A second life for a useful brewing tool

Built for homebrewers. Reborn for the next batch.

OpenBrew is a community recipe workspace for the practical side of homebrewing: building recipes, understanding the numbers, and recording what happened when you brewed them.

The Brewgr story

Brewgr was created in 2011 by software engineers and homebrewers Matthew Marksbury and Jason Zimmerman. They built a simple cloud-based place for brewers to create, share, and improve recipes at a time when tools like that were hard to find.

When the original service stopped operating at the end of 2025, its open-source codebase was still too useful to leave behind.

A fork, rebuilt for today

OpenBrew is a modernized fork of that original codebase: the familiar recipe builder, calculations, sharing, and brewing workflows are being restored carefully, with a cleaner interface and an open path forward.
