The alternative bottling company for wine bottles was founded in 1993 by Belgian entrepreneur Gert Noel and his son Marc in Zebulon, North Carolina, with headquarters in Thimister-Clermont (Liège). In January 2015, Nomacorc became part of the company Vinventions LLC, in which the Noel family owns the largest share. The product range includes various inner sealing closures, such as Nomacorc PlantCorkTM and Plastic corks, but also the screw cap Vintop. With manufacturing facilities in the US, Germany, Belgium, Argentina and China, Nomacorc produces around 2.5 billion wine closures annually. In collaboration with several research institutes, Nomacorc is in the field of basic research oxygen management active with wine. The company manufactures 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 thus produced give a calculable, constant oxygen permeability and protect against undesirable flavors as a result of oxidation. reduction or corked, Reductive notes may be due to chemical reaction during the fermentation due to unpleasant sulfur compounds but also be formed in the bottle. There are different oxygen rates in the range sparkling wines or short-lipped Still wines to long-lasting wines. The selection of a shop for the "right" closure per type of wine is supported by one software, the vine, Production process, wine parameters and variety specifics related to oxygen management.
The products for the long-lasting wines ensure a controlled oxygen management in two phases. In the initial phase, the closure allows almost no oxygen through. On the other hand, during the maturity stage, there is a very low level of constant oxygen transfer called nanooxigenation (see micro-oxygenation ). Corks from the Nomacorc Green Line product line are made from plant-based sugar cane polymers. It includes five brands for wines with different maturity periods or durability as well as different cork length 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 champagne corks Zest Premium (until 2 years).
