Cruvinet is the name of a company which invented a system for dispensing wine similar to the way beer is dispensed on tap. Cruvinet systems, which can be mobile or installed and can accommodate anywhere from two to 120 bottles, immediately recork a bottle of wine. Nitrogen gas is pumped through a valve in the replacement cork to prevent oxidation. This allows a bottle of wine to remain open for up to two weeks without spoiling. The system was invented in 1978, although many different companies make "wine bar systems" today. See: Chamberlain, Chris. "Cruvinet: It's Like Wine on Tap."Nashville Scene. December 21, 2010.
