The Great American Beer Festival lands on Denver October 2-4, along with myriad other craft beer events around town. How to get back and forth? Uber, the car-ride service has launched a promotion called the Battle of the Breweries.

More than twenty beer makers in Denver, Boulder and Fort Collins (where Uber has services) will battle it out to see who can get the most Uber signups. To participate, people can go to Uber's website and click on the logo of their favorite brewery to sign up -- and get $25 bucks of their first ride (new users only).

Odell Brewing officially releases its 25th anniversary beer, 180 Shilling, today with a party in the Fort Collins taproom. Jax Fish House will have its food truck out with guest chef Kevin Grossi from Lola in Denver. There will be live music from the Commoners. The 9.6 percent ABV beer is a play on Odell's flagship 90 Shilling. 180 is a double version of the recipe. It has a "hearty roasted malt base balanced by subtle earthy hops and aged on oak to create notes of toffee, plum, vanilla and dried cherry," Odell says.

Copper Kettle will tap a firkin today that was inspired by the Tequila Sunrise cocktail. They startd with their Imperial Pilsner and aged it in tequila barrels, then added fresh crushed oranges and maraschino cherries giving it a sweet twist with a hint of tequila. CKrêpes & CKatering will be serving food.
