HYDROMETER
Wine Ingredients

Basic facts:

Volume of 1 kg dissolved sugar = 0,63 litres

Weight of 1 litre of dissolved sugar = 1,59 kg

Volume of 1 kg extract = 0,63 litres

Weight of 1 litre of dissolved extract = 1,59 kg

Weight of 1 litre alcohol = 0,8 kg (800 grammes).

Weight of 1 litre of water = 1 kg (1 000 grammes)

Wine comprises:

Residual sugar

2-5% (20-50 grammes/litre) extract (unfermented residues such as
colour, taste, vegetable matter, aromatics)

Alcohol

Water

Example, a white wine with 10% alcohol:

Residual sugar

17 ml

27 grammes sugar (17 x 1.59)

Extract 3%

19 ml

30 grammes extract (19 x 1.59)

Alcohol

100 ml

80 grammes (100 x 0.08)

Water

864 ml

864 grammes

This gives 1 001 grammes, i.e., 1 grammes over 1 kg =
+1 degree on the hydrometer
