Yum…acidy.

RainHarvest Systems has partnered with 5 Seasons Brewery to produce beer made entirely from on-site captured rainwater. RainHarvest Systems, an expert in rainwater catchment systems, and 5 Seasons Restaurant and Brewery, Atlanta’s premier micro brewery, both believe this to be the first micro brewed beer to be made entirely with rainwater in the United States.

As part of the partnership, 5 Seasons Brewery is creating a beer to be used by RainHarvest Systems for publicity events intended to promote awareness of rainwater catchment. The first event [occurred] on September 14th, 2009 at 7PM at The Decatur Square in Decatur, Georgia, during the National Conference for the American Rainwater Catchment Systems Association.
