Pectic enzyme different brands

[Mallerstang]

I just bought more pectic enzyme, and it's a different brand - with a different usage rate on the label. Does anyone know if they make it different strengths, or if it's due to a difference in opinion about how much to use?

Both are powders:

Spagnols says 1.25 tsp per 23 litres, which is about 1 tsp for every 18 litres
Brewcraft says 0.75 tsp per gallon, which is about 1 tsp for every 5 litres

I'm following the package instructions for whichever one I use, but am curious as to why the difference.

I have been confused also. Fruit wines use different rates a d different brands have different rates. I'm not sure. I try to follow directions of receipt and product. It has turned out so far. The densier the fruit the more it requires unless you slow cook them to a pulp but then you change the flavor of the wine if you ask me. I like a room temp breakdown of fruit flavor. The water melon I just started called for 1/2 teaspoon. Which I though was low. Who knows.
