A continuous process for producing a tea extract which contains solubilized tannins and which has good color. Tea solids are extracted from tea leaves using an extraction liquid to provide a tea extract containing soluble tea solids and insoluble tannins. The insoluble tannins are separated from the tea extract and oxidized and solubilized under raised temperature conditions to provide a solubilized tannin liquor. The solubilized tannin liquor is either returned to the extraction liquid during extraction of tea solids or added to the tea extract after separation of the insoluble tannins. The tea extract which contains solubilized tea tannins is collected.
