Wiinesave is 100% pure, food grade argon gas. Argon is totally inert. It is
colourless, odourless, flavourless and has no taste. Above all, it combines
with nothing. That means it has no effect on anything it comes in contact
with. Argon is 2½ times heavier than air! Because of its weight, it
falls through air and rests on whatever lies beneath it. Dispensed into an
open wine bottle, it falls down and lays across the surface of the wine,
forming a barrier between the wine and the air. Each canister yields
approximately 75 uses.
