Prestige Instant Dry Yeast is a premium-quality yeast product designed for bakers and brewers. It offers faster results and consistent performance. Fresh yeast, sometimes called cake yeast or compressed yeast, is a block of fresh yeast cells that contains about 70% moisture and is commonly used by baking professionals. It's pale beige in color, soft and crumbly with a texture similar to a soft pencil eraser, and has a stronger yeast smell than dry yeast.
