Inert Gas System Gas systems work by injecting an inert gas, usually CO2, into the bottle, which pushes the wine out and takes up the volume displaced. Each bottle requires its own valve and plumbing set up, which becomes expensive and unreasonably bulky as the wine selection increases. These systems are expensive to operate, as the cost of the CO2 gas is significant and the plumbing requires constant maintenance. Gas systems also have major operational shortcomings. Bottles must remain fixed, dispensing is slow and every glass poured must come from the same location, which is impractical for a busy operation with multiple bartenders and servers. Replacing empty bottles is clumsy and slow, and sanitation is a constant issue. Patrons sitting in the dining room may not be able to see the wines being poured, and may not know what he or she is actually drinking. Vinfinity® resolves these issues in an elegant and simple way. >back
