This will save the city $500 (£350) per day on the acetic acid it would have purchase to do the same job, said Chris Douville, Boulder’s wastewater treatment manager.
Weak wort, a type of sugar wastewater generated by Colorado-based Avery Brewing Co, will be donated to the city of Boulder for use in its wastewater treatment plant to break down nitrogen. But a growing number of craft breweries in the US are finding new ways to reduce their environmental footprint. Craft brewers turn greenīrewing beer from recycled water is an unusual approach. Getting the legislation to bring recycled water directly into the drinking water supply, would be the first step for mass application, just as Singapore has done with its recycled water plant. His focus instead is on using the beer as a tool to catch the eye of both policymakers and the public. California can’t legally directly pump treated recycled water back into the drinking water supply, so it’s currently not practical (shortage of supply) or cost effective. Mendonca has only made the greywater beer available for sampling twice and says commercialising the product isn’t his first priority. “So if I can demonstrate to people that not only is good, but it’s great, then why wouldn’t you use that water for everything else?” “This is the product people think that water is the most important ingredient,” said Mendonca. Made using the same Nasa water recycling technology as astronaut Scott Kelly used during his year long stint on the International Space Station, the tasting panel couldn’t detect which of the two pints was made with recycled water. Last October the brewery unveiled a version of its regular Mavericks Tunnel Vision IPA made with recycled water after a blind taste test at an urban sustainability conference in the Bay Area.
But when he broached the idea with the Half Moon Bay Brewing Company, a craft brewer located south of San Francisco, owner Lenny Mendonca didn’t hesitate.
Despite this, it took Drinker about a year to find a brewer up for the challenge. While some microbrewers have been working hard to get their water usage down – some to three gallons of water for every gallon of beer – the industry has a high water to beer ratio.
