EASTER HOURS: Freight services do not work on statutory holidays so deliveries will not be made on statutory holidays. We will not be despatching orders containing yeast on days which will result in the yeast sitting on the network over the long weekend. We will be responding to email support over the break. Thanks!
Precipitated chalk (also known as calcium carbonate or acid reducing powder) is used to reduce acidity (raise the pH) in wines (or other brews eg beer) that are too acidic. 60g pack.
Start by dissolving 1/2 teaspoon per 5 litres in a small portion of the must and then mix the treated portion back into the wine.
Retest (or retaste) and add more if necessary.
