Compound product made from isinglass, albumin and gelatine for reducing or eliminating astringency and off-flavours originating from oxidation, roughly handled, over-pressed fruit/grapes or faults in fermentation. In case of serious flavour changes or faults, it can be used in combination with Granucol. Treat with Granucol first and after 1 to 2 days, with Gerbinol Super. At low doses it can also be used for 'rounding' dry wines.
Dosage: 0.5-2 g/10 litre, dissolve stirring firmly in 10x its own volume of water, then add to the wine that needs treatment while mixing thoroughly. Siphon after 2 to 3 days.
