Abstract (en)
[origin: WO9851776A1] The invention relates to a method for producing cold-filtered beer. According to said method, beer is filtered through a membrane filter which is able to absorb calcium ions. After filtration, said membrane filter is cleaned and rinsed with aqueous substances. The washed and rinsed membrane filter can then be reused. The invention is characterised in that an acidic aqueous substance with a pH less than 5.0 is used for rinsing, or in that the substance used for rinsing is treated in order to reduce the quantity of calcium ions it contains. The inventive method provides a means of producing beer with less tendency to gush.
