FIELD: food industry.

SUBSTANCE: grapes are subjected to crushing and destemming; Tannin SR Terroir preparation of condensed tannins at a concentration of 100-15- mg/dm³ is introduced into the produced mash. The mash is sulfited, heated up to 45-55°C, maintained during 2-3 hours and cooled to 20-30°C. The free-run must is separated; the run-off mash is pressed. A mixture of ascorbic acid (50 mg/dm³) and Glutarom preparation is introduced into the must at a ratio of 1:4-6. The must is clarified and fermented to produce wine material for low-oxidised table red wine production.
