An accurate scale is needed for this...
The packs come marked in 'Units
' of 10, 20, or 50
We find that utilization of 1-2 Units will set 10 Gallons of milk, depending on milk and activity of starter desired.
So, how do we measure what we need?
The standard rate of recomended use is 2 units per 26.4 Gallons of milk or 1 Unit per 13.2 Gallons.
Since my last 20 Unit Pack of MA011 (less weight of package) was equal to 17.7 grams then 1 Unit was equal to .89 grams [17.7/20]
Now I have determined that my rate of Utilization is a bit less at 1 Unit per 10 Gallons and have 18 gallons of milk to set. Therefore, I can calculate my culture needed as :
.89 (weight of 1 U culture) x 18/10
= .89 x 1.8
= 1.6 grams of MA011 will set my 18 gallons of milk in the time I want
Please do your own tests to find the utilization rate that works for your milk .
