Case Summary
To promote DB Export, we gave Kiwi men a brilliant reason to drink more beer. Brewtroleum is a biofuel made from leftover brewing yeast. It cuts carbon emissions by 8%, meaning every time a man drank DB Export, he was helping to save the world. Suddenly every sip made a difference, every party was for the planet. We turned 58,000 tonnes of yeast slurry into 300,000 litres of biofuel – enough to supply 62 service stations around the country and to open our own flagship Brewtroleum station.
