Instant vs. Active Dry Yeast on the Package

If a recipe calls for instant yeast, look for the word “instant” on the package. For active dry yeast, look for the full phrase “active dry yeast.” Both are sold dry. If the front says only “dry yeast,” turn the package over and read the mixing directions.

What to check on the back

Instant yeast usually goes straight into the flour. Some active dry yeasts are dissolved in warm liquid first, while some manufacturers also allow their active dry yeast to be mixed with the dry ingredients. Use the liquid temperature and any waiting time specified for your particular product.

Match the weight and the type

When the recipe gives a weight, compare it with the net weight on the packet. For 5 g from a 10 g packet, weighing out 5 g is more precise than judging half by eye. If you need to swap yeast types, follow your yeast maker’s conversion guidance and watch how the dough rises. For an example of a yeasted dough, try our fresh herb focaccia.

Common questions

Does active dry yeast always need to be dissolved?

It depends on the product. If the label calls for dissolving, take the liquid from the amount in your recipe and use the temperature specified on the label.

Can I use the same weight of instant and active dry yeast?

Some makers give a one-to-one swap for particular recipes. Check the product instructions and mixing method before assuming the amounts are equal.
