culture question for raw milk

[scasnerkay]

I am on my way to pick up 4 gallons of raw Jersey milk. I plan on using MM100 and a little FD as I did for my prior make made with a nice cream top milk, so I can compare how they turn out. With raw milk should I use a smaller amount of the starter?

While I haven't moved onto calculating activity and weighting cultures accordingly, I usually use 3/8 teaspoon of starter per 4 gallons of my raw Jersey milk, typically gets things on a schedule on par with the recipes I use.

Typically (meaning, I've seen it this way from several authoritative folks), as a starting point you would use 1/2 the amount of pure culture than you would if using P/H milk.  You'll have to tweak it from there.
