Abstract

Grape juice for wine prodn. is concd. by reverse osmosis, pref. after pretreatment by filtration and/or centrifuging and opt. by pasteurising and/or treatment with pectase. Sugar concn. is increased without impairing grape juice quality, heat-caused irreversible changes are prevented, and quality can be improved by removing part of acid with the water.
