The US company headquartered in Napa Valley was founded in 2007 by Tim Keller (former winemaker). This developed during his MBA studies at the University of California in Davis a special one screw cap, which provides a targeted oxygen supply during bottle storage or bottle aging allows. It is assumed that a continuous supply with oxygen has a positive effect flavorings and colour especially in the case of red wines, which is the result of attempts at AWRI (Australian Wine Research Institute) confirmed. The cap contains microscopic holes through which oxygen (Air) can pass through. A special seal with several layers of plastic is located in the aluminum closure ( polyethylene and polyester). Due to this density, oxygen reaches a very low, constant level OTR (Oxygen Transfer Rate) means quantity through the closure in the bottle (nanooxygenation).

VinPerfect screw caps

According to the company statement, VinPerfect combines the reliability of a conventional screw cap with the oxygen permeability of conventional ones cork (Natural cork) in a controlled form. This enables producers to control the maturation of their wines after bottling. Because the closure can be selected so that it matches the amount of oxygen supplied to the intended storage life of the wine. It is therefore possible to lock the closure to the intended storage capacity or durability to adapt a wine or to determine this via the oxygen permeability of the closure.
