Oktoberfest season is back. Here’s your guide to Colorado’s beer-and-bratwurst-drenched events.

It’s hard to make your way through September in Colorado without running into Oktoberfest. The traditional German celebration has become almost as big a deal as St. Patrick’s Day, and you’ll find events at nearly every craft brewery in the state, beer gardens and mountain towns.

This year, there is also a dogtoberfest, an oldtoberfest and a falltoberfest. Many of these events have similar activities, from stein-hosting to traditional keg tappings, but each has its own unique attributes and they’re spread out all over the state. Enjoy one for us. Prost.

Copper Kettle Brewing

Sept. 9-10. Copper Kettle in Denver hosts one of the larger brewery Oktoberfest parties in the city each year, offering up German-style music, food and games like hammerschlagen) over two days. There will also be branded steins for sale and a stein-holding contest. The brewery will also tap its Oktoberfest lager, along with several other German-style beers, including a hefeweizen and a Dunkel lager. No tickets are necessary; copperkettledenver.com.

Dogtoberfest

Sept. 10.

For dogs, the Fetch Photo Truck will be doing dog photo shoots (signups required) from 2 to 5 p.m., while Clover Dog Co. will be selling dog treats, toys and bandanas.

Vail Oktoberfest

Sept. 9-11 in Lionshead and Sept. 16-18 in Vail Village. Vail’s Oktoberfest has an unfair advantage every year since it is located in a town with a plethora of pseudo-Bavarian architecture and very real mountains. That setting is part of why it was named among the 10 best Oktoberfests in the U.S. by USA Today. But the free, family-friendly celebration also boasts a heavy metal polka band, among other musical acts, a keg-bowling championship, bratwurst-eating contests, German food, costumes, a stein-lifting contest, and plenty of beer, available for sale in three sizes of German-style steins; oktoberfestvail.com.
