OTR

Abbreviation (Oxygen Transfer Rate) for the amount of oxygen that passes through the closure into the filled wine bottle. As a rule, the amount is relatively low with conventional screw caps and relatively high with corks (natural corks) with a factor of three to four. Oxygenation in such a small quantity is called nanooxigenation. See also micro-oxygenation, bottle ageing and oxygen management.
