A new collaboration between Stone Brewing Co., Aleman Brewing Co and Chicago, Ill.-based Two Brothers Brewing Co. is an imperial version of a beer that won first place at the Iron Brew home brewing competition.

The new beer is Champion of the Sun, a 9.1 percent ABV imperial IPA brewed with coffee beans sourced from Five Elephant. An earlier version of the IPA was brewed by Jim Moorehouse, Nate Albreht and Brad Zeller of Aleman and won first place at the Iron Brew home brewing competition that was judged by both Greg Koch from Stone and Jason Ebel of Two Brothers, among others. That beer was eventually brewed and released by Stone as Dayman Coffee IPA (8.7 percent ABV) in 2013.

The IPA is one of Stone’s Groundbreaking Collaborations that has been brewed at Stone’s new Berlin facility, which opened in September 2015 after more than a year of construction. In 2014, Stone launched an Indiegogo campaign to help crowdfund the Berlin-based brewery. Contributors of the project were promised 1.5l bottles of 14 collaborative beers brewed at the German facility.

However, a label filed with the Alcohol and Tobacco Tax and Trade Bureau (TTB) indicates that Champion of the Sun will be offered in 750ml bottles. In addition, a calendar on Stone’s website indicates that the IPA was brewed in Berlin on Jan. 17.

An email sent to the brewery for additional information was not immediately returned.
