There are many taxes, all of which end up as a percentage of beer production cost.
Most states you pay property taxes on the building. In some you also pay property tax on all the equipment, vehicles, supplies, etc. In Oregon you will pay property tax on every bit of equipment of any kind that is not already being taxed as part of the building. Also all sales material, brochures, glassware, and office supplies down to paper clips -- everything used except ingredients to make beer or finished beer inventory. It's nuts.
Also, if you have employees you will be paying FICA tax, workers comp, unemployment, and probably more depending on state and city. And if you manage so show income after all expenses then you will be paying income tax on that too.
