A process for the crossflow-microfiltration of wine from a storage container through a membrane filter with membranes having a nominal pore diameter of 0.1-5 m, in which the mean velocity in the membrane filter is 0.5-6 m/second, wherein before entering the membrane filter the wine is warmed to a temperature which is above a temperature threshold that produces a definite increase in filter performance but at the most to 45 DEG C. Crossflow-microfiltration is carried out without addition of filtering aids and the filtrate obtained is cooled to storage temperature. An apparatus for carrying out the process comprises a storage container, a membrane filter with a nominal pore diameter of 0.1-5 m, a feed pump and piping, a heating device being attached upstream of the membrane filter and a cooling device and filtrate container being attached downstream therefrom. |
