The storage life of wine from Bangalore blue grapes (Vitis labrusca) is limited by the change of the desirable pink colour of the wine to a yellow hue. The wine may be kept untreated for up to 9 wk at 7 degree C with 91.7% retention of colour (measured spectrophotometrically at 520 nm). Addition of potassium metabisulphite or sodium bisulphite extended the storage period to 50 wk with retention of 68.8% and 66.7% of original colour, resp., and no browning. Storage life and colour retentions were 20 wk and 68.8-75.8% at room temp. (22-28 degree C) and 6 wk and 70.9-78.6% at 37 degree C for the sulphited samples.
