First off, I've been to a lot of breweries and brewery tours, this by far has been my favorite means of doing so!
The initial price you pay includes all beer**, the tour bus fee and all the tour info and brewers time provided by each brewery (each is different).
**that's unlimited beer for 3 hours!!!
Each brewery was so welcoming. We went to Northgate, socialable ciderwerks and boom island.
The bus driver, Eric, was awesome, total sweetheart and very welcoming. You can tell great customer service is a priority in there company!
I do recommend tipping ALL staff, as you can tell they care a great deal about your experience (brewery staff and drivers)
Great job guys!
