How to use it

  1. Enter dry yeast weight and yeast type.
  2. The result appears straight away and updates as you edit.
  3. Copy the result, or copy a link that keeps the same values to share it.

How it is calculated

Fresh = instant ÷ 0.33 or active dry ÷ 0.4. Instant = active dry × 0.825; active dry = instant ÷ 0.825.

Example

Inputs: Dry yeast weight = 10 g, Yeast type = Active dry. Result: Fresh yeast: 25 g; Or instant yeast: 8.25 g.

Limits and caveats

  • The 0.4 and 0.33 ratios are common baker references, not fixed for every brand.
  • Fresh yeast spoils within weeks in the fridge, so check it is still active.

Questions about this tool

How much fresh yeast replaces a 7 g sachet of instant?

About 21 g of fresh yeast.

How do I use fresh yeast instead of instant?

Crumble it into some of the warm recipe water or rub it into the flour, then carry on as usual.

Should I change the water?

The difference is small in most recipes, since the water in fresh yeast is tiny next to the dough water.
