Managing Oxygen at Packaging Wes Ward, Nomacorc Oxygen Management Technology NOMACORC Research Nomacorc has partnered with renowned wine institutes around the world to conduct cutting-edge fundamental research in the area of oxygen management in wine. Our Academic Partners Geisenheim UC Davis INRA AWRI PUC But also… BPHR Asti Research Center Universidad Valladolid Conzortio Tuscania IFV COFCO China Stellenbosch Talca What do we mean with Oxygen Management in the Winery? Being able to deliver the right amount of oxygen in a measurable and reproducible way at each step of the winemaking process in order to meet the winemaker intention and the consumer expectations Is Oxygen Management Important?
