International Beer Day: a toast that can combat water pollution

Beer is one of the most popular drinks in the world. In every place in the world you will find a unique and representative variety of its culture. But did you know that it plays a key role in the fight against pollution, and that its production is being affected by climate change?

International Beer Day is a celebration that unites people from all over the world in bars, breweries and any place where it can be provided with a well-filled jug. This celebration began in 2008 from a proposal by the California Brewers Association, and during the last decade its popularity has been increasing.

The first Friday of August has been established as the day on which more than 200 cities around the world celebrate their passion for this drink. The reason is none other than to enjoy some beers in the company of friends, and take the opportunity to pay tribute to all the people in charge of manufacturing and serving the beer.

It is the ideal day to try new varieties and explore the different nations and cultures that provide their own identity in the manufacture of beers. Spain, as a Mediterranean country, is one of the world’s largest consumers and is enjoyed with responsibility, moderation and in society.

Beer, despite being one of the most consumed beverages in the world, could be one of the biggest victims of climate change. Heavy droughts affect agricultural production, and inevitably have an impact on barley crops, the main ingredient. Some of the most direct consequences could be the limitation in exports, the increase in prices, the shortage of supplies and, ultimately, a destabilization of the global market.

Beer, key to saving rivers and seas
On the other hand, it could also play a key role in the fight against water pollution.

According to a study led by the Center for Advanced Studies in Blanes, waste from brewing could be a very effective method to remove nitrates from water in rivers and seas. The dumping of these wastes could increase bacterial denitrification rates up to 40%, as well as combat the proliferation of microalgae and improve water quality.
