$6.40

Pectolase/Pectinase breaks down the pectins found naturally occuring in fruit, releasing juice, colour and flavour and enhancing yield. If pectins are not destroyed then there is a good chance your finished wine will remain "hazy" and never clear, even with the use of finings later on. It is recommended you add 1 heaped teaspoon of enzyme per gallon (4.5 Litres) of wine to prevent hazes. If your fruit has been heat treated then double the dosage rate. Enzymes need to be kept fresh, use up and replace every 6 months if possible, definitely every year, old enzymes do not work.

Pectolase should be added before fermentation is allowed as enzymes do not work well in the presence of alcohol. Add at the same time as addition of Campden OR Potassium Metabisulphite allowing 12-24 Hours for them all to work together before either straining fruit juice from pulp to continue on to do a juice fermentation (our recommendation) or adding the yeast in with the pulp itself to do a pulp fermentation.

If you have a stubborn "hazy" finished wine that isn't clearing even with the use of finings you likely have a Pectic Haze. You can test for this by using some methylated spirits on a sample of the wine and seeing if "clots" form, if they do it still contains pectin. You can try adding 2 heaped teaspoons of pectic enzyme per gallon of hazy wine to see if it will destroy it, but this is not always successful.

Pectinase breaks down the pectins in fruit, releasing juice and flavour and enhancing yield. It is used primarily in fruit and white wine making. Keep refrigerated. Pectinase should be added whilst the fruit is being crushed. Prepare 1 t spoon (5g) of Pectinase per 5kg of fruit in a 100ml warm water solution. Stir through the pulp. Leave for a minimum of 6 - 12 hours before pressing. Pulp: Add 1 tspn per 5L directly to pulp, leave two hours @ 50C before diluting for main fermentation.
