At the end of the tour, visitors who are 21+ get one, six-ounce pour for free. (It's $5 to get two full-sized beers.)
The Fort Collins brewery has two special attractions that many other breweries do not. It has a Biergarten where you can buy food, and the Fort Collins brewery is the home base for a Clydesdales team. Watch the website for announcements on special events involving the Clydesdales.
New Belgium Brewery
New Belgium Brewery, the company known for its Fat Tire Ale and other brews, started in a Fort Collins basement in 1988 and went commercial in 1991.
While New Belgium charges for tasters, pints and growlers in the Tasting Room, if you take a free 90-minute, guided tour, you get 3 to 4 tasters along the way. The tasters are four, or so, ounces each.
