How to Use This Calculator
  1. Enter milk volume in mL.
  2. Select culture type: mesophilic (room temperature, 12 hrs) or thermophilic (110 °F, 8 hrs).
  3. Choose target thickness (thin drinkable, medium spoonable, or thick Greek-style).
  4. The calculator shows culture amount in mL, incubation time, target temperature in °F and °C, and estimated yield.
  5. Heat milk to the target temp, cool slightly, stir in culture, then incubate undisturbed for the full indicated time.

What each input means

Milk Volume (mL)
Volume of milk in milliliters. 1 liter = 1000 mL.
Culture Type
Mesophilic cultures at room temp. Thermophilic needs a warm environment (110°F).
Target Thickness
Thicker yogurt requires longer incubation. Greek-style involves straining whey.
