Everything is here in my brewing closet. There's a 4th shelf at the top (not in pic) that has small storage drawers for spices, dry yeast, etc. Behind the bins is where I keep a bunch of other stuff like my portable control panel, etc. This closet is unique in that it has doors on both sides, so I can maximize shelf usage that way (very deep shelves).
I've got one of those huge rubbermaid storage sheds outside for all the large brewing gear. I brew out there, so it never comes in the house (only perishables inside).
