I am often asked what constitutes the 'Misc. Costs' item in your batch costs and I'll provide an explanation here. It's basically a random number on each batch, these are the misc. costs (gasgets, replacement parts, etc.) that go with operating a brewery. In the real world this number would be a much higher percentage of your total operating costs. In the game its just a tool that helps keep the game balanced, fun, and challenging and adds a small touch of realism to brewery ownership.
