Hey. I started working on this when I saw the blog post about adding booze, but I unfortunatly only finished now after it's already been put in. For what it's worth though I'd like to suggest expanded brewing, to flesh it out a bit. This is something I've wanted in MC for a while.

Even this is simplified from real brewing, but most of the main steps are there. Boiling and fermenting are very important or else it just isn't beer at all. It's wheaty hop water. Some steps could be removed for the sake of simplicity like the milling stage, but it would be a good use of the macerator.
I did a mock up here.

The textures were just placeholders I made but I'd hand them over if you want to work on this and expand on brewing.
