We had Marcus as our tour guide for the Stiegl brewery tour, and he did a great job! The tour…read moreitself was interesting, informative, and definitely worth doing if you're visiting Salzburg.
My only suggestion would be to rethink how the beer tastings are worked into the tour. The entire experience, including the free beers, is listed as around 1.5 hours, but you don't really sit down to enjoy the beers until after the actual tour is finished. You get two pretty large beers, so drinking both can easily add quite a bit of extra time. I know this isn't something the tour guide controls, but it would be nice if you could enjoy a beer while walking through certain parts of the tour, or if they simply allowed more time at the end for the tastings.
Overall, though, the tour itself was very good, Marcus was a great guide, and we enjoyed learning more about Stiegl and the brewing process. Definitely just plan for more than 1.5 hours if you actually want to sit, relax, and enjoy the included beers afterward!
