Chemicals - Precipitated Chalk (50g)
Quantity in Basket: none
Code: CHE020
Price: 1.45

Shipping Weight: 0.00 kilograms
To reduce acidity in wines the addition of 7g per gallon will lower the acidity by about 1.5 PPT. The liquid will start to foam because gas is given up by the chalk as it neutralizes some of the acid.

Obviously this must be done in vessel from which some of the juice has been removed to allow adequate headspace for the foam.
