Food grade argon Е938 – is the simplest and most effective solution for keeping opened bottles of wine and other packaged foods fresh for days, weeks or months.   Consists of 100% high-quality food-grade argon E938, which is completely inert, completely harmless, colorless, odorless and tasteless.   Argon is heavier than air and sinks below the air level in the bottle, forming an ideal protective layer directly above the wine, reducing oxygen absorption and oxidation. Suitable for all types of wine – red, white, sparkling (with any fixing stopper), as well as for storing any other food products.
