Loop

Fermentation growth curve

You might say: yeast growth, how fast the dough rises

Fermentation moves through acceleration, a period of maximum gas production, and then slowing with weak gassing.

What it does
Explains why the rise speeds up, peaks and then slows as fermentation conditions change.
Ask
Where on the curve is this dough: still accelerating, near its peak, or past it?

What to look for

  1. Dough barely moves at first, then rises fast, then levels off
  2. Growth slows as the dough smells and tastes more sour

Gelinas, Baker’s yeast sampling and frozen dough stability, p. 609three steps could be observed during fermentation: 1) an acceleration period corresponding both to initiation of the yeast metabolism and to equilibration of the dough temperature with the 28°C of the water bath; 2) a period with constant and maximum fermentation rate; 3) a slowing down period of gas production
