I have a brewery producing 40 units of beer per month, but not consuming any woodchips in the process. The brewery did not start production until all reagents were delivered, but no woodchip has been used.
The brewery claims to use grain (83%) and woodchip (17%), so I would expect it to need about 35 units of grain and 7 units of woodchip per month, but it is actually consuming 10 units of grain and no woodchips according to its information window.
