A lot of recipes out there call for two gallons of milk. I usually make goat cheese with ten gallons of milk. I have just kind of improvised, and things have worked out fine, but I wonder if there is a conversion rate for adding culture and rennet.
For example, if a recipe for cheese with two gallons of milk calls for 1/4 teaspoon rennet and 1 teaspoon rennet, how do I convert this to a batch with ten gallons of milk?
I love to make Gouda and Cheddar.
Thanks,

In general, it is 9 ml of single strength rennet per 100 lbs milk (about 200 IMCU strength). In terms of culture, for starter culture it is as follows:
Bulk % Danisco DVI equivalent CHR Hansen DVS CHR Hansen DV frozen pellet
0.50% 3.25 DCU per 100 liters 5 U per 100 liters 5 g per 100 liters
1.00% 6.5 DCU per 100 liters 10 U per 100 liters 10 g per 100 liters
1.50% 9.75 DCU per 100 liters 15 U per 100 liters 15 g per 100 liters
2.00% 13 DCU per 100 liters 20 U per 100 liters 20 g per 100 liters
Normal rate for most cheeses is from 1.0% to 1.5% bulk equivalent. So for example the 25 DCU pack is good for about 200 liters of milk.
