The New Belgium Brewing Company offers tours all year round. They have multiple tours a day, but they are also very popular, so it helps to make an online reservation ahead of time. Like most breweries, guests of any age can tour, but only those who are 21 can take advantage of the samples along the way. The tours are free and last 90 minutes so you can see the entire brewery at a casual pace.
Deschutes Brewery was actually the original brewpub in Bend, Oregon and this is where Deschutes Brewery made their very first beers. Tours start in the Tasting Room and are guides and completely free. Along the way, you get to learn about every aspect of brewing, including the methods, tools, and ingredients that make this brewery different. There is only room for 15 people on each tour and you can make your reservation 3 months ahead of time. Although those over 12 can go on the tour, the four complimentary samples only apply to those over 21. Plan on the tour taking 45 minutes.
This brewery offers two types of tours: self-guided and guided. Self-guided tours are free, but guided tasting tours cost $5, which is well worth it as you get beer samples and a souvenir glass. Because guided tours only have room for 10 people, it helps to make a reservation. Even the free self-guided tour will teach you everything you want to know with informational cards along the way.
Sierra Nevada Brewing made their very first batch in 1980. Now there are two locations, including the original in Chico, California. The Brewhouse Tour is open to those who are at least 12 years old and includes the chance to smell hops, look into giant beer kettles and learn about the beer-making process. Those who are of legal age then get to enjoy an educational tasting.
Olde Mecklenburg Brewery is modeled after a German Bierhall and includes a Tap Room as well as restaurant. You can go on a free tour of the brewery on Saturdays or Sundays (with three time slots), whether or not you buy anything. Feel free to bring along your children as long as they are with at least one adult who is 21 or older. The tour, or "group experience" lasts 40 minutes and there is enough space for 50 people per tour, so you don't have to worry about a reservation. You can also schedule a paid private tour if you prefer.
