We went on a Mon thinking it wouldn't be very crowded. We were wrong! They had to split us into 2 tours - about 50 ppl in our group and 75 in the group after us.
You MUST wear closed toe shoes. If you show up in flip flops, they refer you to their box of sneakers you can look through to borrow a pair - kinda like the bowling alley. ha
On a weekday, the brewery is running. They still give the tour on Sat but the machines aren't running. This is the smaller of their plants but there is so much history here you don't want to miss it. It's FREE. No beer sold here but adults will get 2 free samples at the end of the tour. In town, there is a beer "outlet" (not discounted so not sure how they call themselves an "outlet") where you can buy some of the beer.
The tour ends in their gift shop. How convenient. ;-)
