The Fundamentals of Milk Fermentation
Kefir grains are living symbiotic settlement of bacterium and yeasts (SCOBY) that consume lactose.

Conversely, if you use too few grains, the milk may spoil before the acidity drops sufficiently to preserve it.

💡 Line: Always use room-temperature milk when start a new batch to forefend thermic impact to the grains, which can cause them to get sulky regardless of the ratio used.
Managing Grain Growth
