An ever-rotating selection of Sprecher craft beer is on tap at each tour stop. While Sprecher remains the featured beverage at the TBG, we also offer options from Third Space, New Glarus, and 3 Sheeps Breweries. Cider, gluten-free options, and non-alcoholic beverages are available as well.
Bring your own Parks Beer Garden branded (or other) pint glass to pay the refill price! All standard pour pricing comes with a commemorative glass to take home.
Here is the full menu.
