Microoxidation

Often used but not correct term for microoxigenation; see there.

1 = Oxygen cylinder through which pure oxygen (O₂) is introduced into the system

4 = Wine tank - vessel in which the controlled introduction of oxygen takes place

Oxygen supply

In this relatively new winemaking technique (also known as microbullage), the colour or flavour development of the wine is optimised in a targeted manner by adding the appropriate amount of air or pure oxygen to the must or young wine. Patrick Ducourneau made his first attempts in 1991 to reduce the very high tannin content of the Tannat grape variety. Today, the process is used worldwide in many red wine styles to polymerise tannins, stabilise colour and refine the texture.

Difference to oxidative ageing

Micro-oxygenation differs significantly from the oxidative ageing of wine types such as certain varieties of Madeira, Malaga, port and...
