What Is Fresh Yeast?
Fresh yeast is the fresh form of the live cells of Saccharomyces cerevisiae used in breadmaking, sold as moist, compressed cubes or blocks. Unlike dry yeast, it has not been dried.
It is light gray-beige, soft and crumbly in texture, and has a distinct yeasty, bread-like smell. It has long been preferred in bakeries and traditional home baking.

Fresh yeast can be rubbed directly into the flour or dissolved in a warm liquid; it is generally used at 2 times the amount of dry yeast. The rising time may also differ slightly.
Frequently Asked Questions
Can fresh yeast be substituted for dry yeast?
Yes, but the ratio changes; as a general rule, use approximately 2–2.5 units of fresh yeast for every 1 unit of dry yeast.
Why does fresh yeast spoil quickly?
Its high moisture content causes the live yeast cells to lose activity quickly and makes the yeast more prone to mold; for this reason, it has a much shorter shelf life than dry yeast.
Is fresh yeast available in Türkiye?
Yes, it is widely available; most grocery stores sell it refrigerated in the baking supplies section.
