Important advantages of direct SO2- injection into empty bottles prior to bottling of wine are reported: 1. In advance determined SO2-amounts injected into the empty bottle: 2. sterilization of the inner bottle walls: 3. intensive antiseptic SO2-effect on wine microorganisms. Molecular SO2 very quickly kills yeast and bacterial cells. The binding ability with wine constituents (acetaldehyde, polyphenols) is very slow. Sulphur dioxide may be injected as concentrated water solution or in wine that is to be bottled. The antimicrobial effect of SO2 in water solution or in wine at low pH is compared with kaliummetabisulphite (K2S2O5) solutions.
