We do not require a rental fee to reserve one of our spaces, just a minimum tab depending on the date and time. All orders by your guests count toward that minimum tab (including beer, food, and merch), so hopefully that means there is no additional charge. Rentals that require us to shut down the entire brewery taproom are available, but have an additional fee.
The full brewery is also available for parties of up to 200. Reserving the entire brewery requires us to close to the public (and thus is more expensive) so we typically recommend smaller parties reserve the brewery area, beer garden, or both.
