Put the pectolase in at the start of preparing the must or fermentation.Pectolase works slowly at fermentation temperatures.
The wine must has to be cool when its added.(important)
Pectolase is destroyed by heat
The wine should then be free of pectin as it settles down to clear.
It occurs naturally in fruit but is normally deactivated during juice extraction by heat.
So its not really an alien "chemical"
1/2 to 1 tsp/gal is usually enough.
Some fruits are so high in pectin you cant make clear wine without using it
Store it cool and use it fresh.
If you are making a fruit wine 1kg sultanas/raisins to the gallon is too much.
About a 1/4 of that amount is nearer the mark.
You can still get the benefits even using 100g to the gallon.
They have a very penetrating flavour and can easily overpower your fruit.
Thank you John. The plan for the sultanas was to use them as part of the flavour, (as opposed to for extra tannin or nutrient purposes) along with ginger. Does the same still apply?
Also I don’t typically use heat, I use the steeping from frozen method with the sugar. It’s all so complicated arghh lol. I will follow your advice and see what happens.
