Abstract
Disclosed is a method for filling barrels (,), specially kegs, with liquids, wherein at least one gas is dissolved. The barrel (,) is pre-stressed using a gas before the liquid is filled. Liquid is then fed into the barrel (,) by means of a filling valve (,) pertaining to a filling station (,) and connected to a feed line (,). During filling, the pre-stress gas contained in the barrel (,) is evacuated. So as not to impair the product, the pre-stress gas in the barrel (,) is pre-stressed at only a partial pressure which corresponds approximately to the saturation pressure of the CO,or N,which is dissolved in the filled liquid. Said partial pressure is lower than the maximum product pressure occurring in the feed line (,) prior to the filling valve (,).
