Sourdough starter peak prediction.

How Lievanto estimates sourdough starter peak time from feeding history, feeding ratio, and temperature, plus what to log for better predictions.

What the app tracks.

Starter peak prediction starts with the variables bakers actually control: feeding time, starter weight, flour, water, flour type, and the temperature around the jar.

  • Log feedings with ratio and temperature, not only a timestamp.
  • Add observations as the starter rises, domes, flattens, and recedes.
  • Use the estimate as a planning window, then confirm with the starter itself.

Why temperature belongs in the model.

A starter fed at 18°C and the same starter fed at 25°C are not on the same clock. Lievanto uses a simplified Q10 model so the estimate moves when the kitchen changes.

Where this helps.

Peak prediction is most useful when you want to mix at a specific time, build a levain for an overnight dough, or stop guessing whether the starter will be ready before bed.

FAQ

Common questions.

Can any app know the exact starter peak time?

No. Starter strength, flour, temperature, jar shape, and observation quality all matter. Lievanto gives a planning estimate and keeps the visible cues in the loop.

What should I log for better predictions?

Log the feeding ratio, flour and water weights, ambient temperature, and a few observations around rise, dome, peak, and collapse.
