Insta Ferm Instant Yeast Dry is instant dry yeast obtained from a specially selected strain of Saccharomyces cerevisiae. Designed for use in regular bread and high-sugar dough with up to 10% sugar. Use in any recipe calling for active dry yeast: artisan loaves, pizza, sandwich bread, bagels, rolls, and more. No need to adjust the amount, use just as the recipe says. This yeast will keep for a year or more stored in an air-tight container in the freezer. Dry yeast comes in two forms: active and instant. "Active" describes any dry yeast that needs to be activated prior to use, while "instant dry yeast" describes any dry yeast that's ready for use the instant you open the package. Instant yeast has more live cells than active dry yeast. This is what allows it to be so fast-acting. Unlike active dry yeast, instant yeast does not need to be dissolved before it's added to the other ingredients.
