O
Oud Bruin
“Old brown” in Dutch. Top-fermented beer, burgundy-brown in color, with a sweet-and-sour aroma and taste. One of the most surprising types of beer, and one that can be very refreshing. Typically represented by Rodenbach (in the same vein, there are also Vichtenaar, Oud Piro, Zulte, Petrus...).

Oxidation
Deterioration of beer through contact with oxygen, which over time gives it flavors of wet cardboard, sherry or honey. Slight oxidation can, however, be appreciated in some strong beers made for aging (see Foam).
Oxygenation
While the wort is cooling, it can be oxygenated in order to promote the action of the yeast during fermentation.
