Colorado Craft Root Beer is proudly brewed in small batches at Mighty River Brewing in Windsor, Colorado. We use only real roots, spices, and pure cane sugar — no high fructose corn syrup, no artificial flavors, and nothing you can't pronounce.
Our recipe has been refined over years of tasting and testing to create the perfect balance of spicy, sweet, and herbal notes that will transport you back to the root beers of your childhood — only better.

Licorice-like brightness and aromatic lift.
Rich chocolate notes without the sugar.
