Cyberbrau is a Web-based program to help the homebrewer. It allows for very simple and intuitive beer, mead and cider recipe creation, and it automatically calculates all the pertinent information based on the selected ingredients and schedule.
In addition to the recipes, it allows multiple brewers to track their batches, emailing them on racking, bottling, and lagering dates. Finally, it has a 'taster's review' section which allows those who try your brew to rate and comment on the batch. This information goes into the overall recipe ranking.
