We only came here for the brewery tour, which was $10 (tour + beer), but we opted for the $15 (tour + beer + beer schnapps tasting).
We came on a Saturday after and were the only ones on the tour, but our guide was SUPER knowledgeable about the history of Mills brewery and answered every single question we had (we had a lot). Really chill dude with origins at Muskoka brewery (forgot his name) and was very generous with the beer. We got the organic lager for the duration of the beer and came back to the bar for four different samples of their draughts, as well as small samples of their beer schnapps.
If you're someone who enjoys beer - I would definitely recommend this tour and come with lots of questions!
