How much starter for 500g flour?
The answer
Starter is usually given as a percentage of the flour. For 500 g flour with a 100% hydration starter:
| Starter | Grams | Its flour | Its water |
|---|---|---|---|
| 10% | 50 g | 25 g | 25 g |
| 15% | 75 g | 38 g | 38 g |
| 20% | 100 g | 50 g | 50 g |
| 25% | 125 g | 62 g | 62 g |
How it is worked out
Multiply the flour by the percentage: 500 g × 20% = 100 g. A 100% starter is equal weights of flour and water, so each gram of it adds half a gram of each to the dough. The calculator below starts at 20% and 70% hydration as an example.
