Starter Cultures, Freeze Dried - Rehydrating?

[Buth Dairy]

Hello,

Does anyone out there have any information on how long and under what conditions (volumes, temperature, etc) you should rehydrate cultures before adding them to the milk? If you wait too long vs. not long enough, etc......I know non-chlorinated water is required. Difficult to find anything online.

Thank you!

Which cultures? The point of DVI is that you add directly to milk with no intermediary step.
