Hi Dave-odave-o wrote:You need a lot of fruit to have any effect, perhaps 4kg of raspberries in a 5 gallon brew.
I'd add them after the initial fermentation has died down, and of course pasteurise them first. You might want to add pectic enzyme too or it will be cloudy, but not in a "good" way.
Think I may add pectolase to this if the cloudiness is likely to be 'globby'
Q. What is the dose per 1lb of raspberry fruit.
Q2. Can I add it during fermentation without affecting yeast metabolism. If so will the products of the broken down pectin (a polysaccharide) be fermentable sugars?
Q3. Will it catalyse the breakdown of pectin at fermentation temperatures 20 degrees C?
Q4. Will an overdose of pectolase give off flavour or other problems?
