Plan milk kefir with reusable kefir grains, whole milk and a room-temperature fermentation.
The simulator above opens with this recipe's milk, starter, heat step, temperature and taste targets pre-selected. Adjust them to match your ingredients and kitchen.
Starting ingredients and settings
Milk: Whole milk (3.25%)
Starter: Heirloom Milk kefir grains
Starter dose: grains 1 : 20
Heat step: No heat step
Method: Countertop
Incubation: 22 °C; simulation window: 26 hours
Plan your batch
Use whole milk (3.25%) without a separate heat step for this preset. Bring it to 22 °C before adding the culture.
Add Heirloom Milk kefir grains using the starting dose of grains 1 : 20. Follow the culture supplier's instructions for activation and dosing.
Use Countertop at 22 °C. The simulator explores up to 26 hours; use the predicted ready window and the cook-along to plan your batch rather than treating the full window as a fixed fermentation time.
Separate the kefir grains from the finished kefir, then refrigerate the kefir.
These are starting defaults, not a guaranteed outcome. Check the simulator’s warnings and science sources for your chosen milk and culture.
