Oxygen pickup – new filling technology is the answer
Oxidation processes | Brewers are all too aware of the fact that beer is probably the beverage that reacts most sensitively to oxygen. What is known as the oxidation off-flavor occurs if there is too much oxygen pickup. Trend beers made using the rediscovered cold or dry hopping technique quickly alter their taste with oxygen pickup. Standard light beers are also especially sensitive to oxygen, however. Dark beers, on the other hand, often display considerable flavor tolerance to an oxygen content of above and beyond 0.1 mg/l.
