If you have heard of Coors, you probably have heard of the town of Golden. Just a skip from downtown Denver (about 15 minutes to the brewery), it is worth the journey to see. Coors has a big tour that runs every day. Golden is right next to the foothills and is basically just a suburb.
Anyway the tour runs 45 minutes and gives the brewing experience from beginning to end. You are able to smell the hops (kind of weird but interesting) and see the malt being roasted.
The start of the tour is like a small gallery of advertisements and history. You get a genuine beer bottle label and when your label is called, you are on your way to seeing the brewing process.
The tour is over a mile long and has stairs - just so you know. The children will like this tour as well - it gives a lot of insight on responsible drinking. The canning process is a kid thriller.
The end of the tour is the sampling session. There are alternate beverages for those not interested in beer at the moment and a gift shop if you are Coors crazy.
