The manufacturer of alternative closures for wine bottles was founded in 1993 by the Belgian entrepreneur Gert Noel and his son Marc in Zebulon, North Carolina. The European headquarters are based in Thimister-Clermont (Liège). In January 2015, Nomacorc became part of Vinventions LLC, in which the Noel family has the largest stake. The product range includes various internal sealing closures, such as Nomacorc PlantCorkTM and Plastic corks, but also the Vintop twist lock. With manufacturing facilities in the United States, Germany, Belgium, Argentina and China, Nomacorc produces around 2.5 billion wine closures annually. In collaboration with several research institutes, Nomacorc is involved in basic research in the field oxygen management active with wine. The company produces its extensive range using a patented CO extrusion process. The corks consist of an oxygen-permeable inner core and an elastic outer shell, which ensures a tight seal.
According to the manufacturer, the closures produced in this way result in a calculable, constant oxygen permeability and protect against undesirable taste notes as a result of oxidation. reduction or corked, Reductive notes can be obtained through chemical reaction during the fermentation due to uncomfortable sulfur compounds, but also be formed in the bottle. There are different oxygen rates in the range sparkling wines or short-lived Still wines to long-lived wines. The selection of a company for the "right" closure for each type of wine is supported by the software that vine, Manufacturing process, wine parameters and variety specifics in relation to oxygen management are taken into account.
The products for the long-lived wines ensure controlled oxygen management in two phases. In the initial phase, the closure allows almost no oxygen to pass through. During the maturity stage, however, there is an extremely low constant oxygen transfer called nanooxygenation (see below micro-oxygenation ). The corks of the "Nomacorc Green Line" product line are made from plant-based polymers made from sugar cane. It comprises five brands for wines with different maturation periods or durability as well as different cork lengths from 36 to 53 mm. The individual corks cause a different oxygen transfer. These are Reserva (up to 25 years), Select Green (100 to 15 years, 300 to 10 years, 500 to 8 years), Classic Green (up to 5 years), Smart Green (up to 3 years) and the Zest Premium champagne cork (up to 2 years).
