Cero Coffee Roasters is a certified B Corp micro roastery established in Madrid in 2017. They roast on Coffee Tech equipment, using Ghibli and Silon roasters to produce specialty coffee with a focus on natural and organic offerings. Their philosophy centres on making quality coffee accessible while keeping the full supply chain visible, from cherry harvest through to the finished roast. Cero supplies both direct consumers and business clients across Europe, and also offers private label solutions for events and corporate partners. The roastery is open to the public in central Madrid.
