BrewComputer can become the main tool for any homebrewer or a small craft brewery. Its core tool is a recipe calculator. With BrewComputer, you can create, adjust and calculate recipes, record brew sessions, manage equipment, share recipes with other brewers.

BrewComputer - a free homebrew recipe calculator. We are a team of software developers and are also passionate about homebrewing. We created BrewComputer to test our own software framework, this is why it is free. We are going to keep the basic functions free forever. We are also working on a new recipe interchange format – BeerJSON, and hope the industry adopts it. BrewComputer's core tool is a recipe calculator. It also has additional calculation tools covering various aspects of brewing as well as unit conversion tools. Batch session recording and recipe sharing are also available.
