One the of co-founders here (George). I totally agree with you here. One of the challenges we have is just the pure amount of information a real business has and the realities of getting that information shared. We piloted most of the beers on a custom built 15 gallon system and in the future many new beers maybe be "designed" on the bigger 15bbl system. The 15 gallon system is bigger than most homebrewers use and going bidirectional from 5 gallon to 15 bbl is a bit more complicated than just linearly scaling the recipes. I would like to add a feature to the website that lets you choose the batch size but just need to find the time to do it! Long story short we are still committed to being open source and feel free to keep us honest on that front. If there are particular things you interested in please don't hesitate to contact us directly.
