ABOUT BREAD MACHINE YEAST
Source: Red Star Yeast

RED STARŪ Bread Machine Yeast is a fast acting yeast with excellent performance in bread machines. Ascorbic acid, a dough conditioner, is added to help dough stretch easily.

TO USE ACTIVE DRY YEAST IN A BREAD MACHINE:
use 3/4 teaspoon of yeast for each cup of flour and have liquids at 80 degrees F liquids. Active dry yeast is not recommended for use on one-hour or less bread machine cycles.

For bread machine baking on regular cycles, use 1/2 teaspoon Bread Machine Yeast for each cup of flour and 80 degree F liquids. For one-hour bread machine cycles, yeast amounts must be doubled or tripled; suggested liquid temperatures vary with machines.

Bread Machine Yeast can be used for traditional baking as a fast acting yeast. When mixed with dry ingredients, heat liquids to 120 to 130 degrees F. To hydrate before combining with other ingredients, use 110 to 115 degrees F liquids. For traditional baking, 2 teaspoons Bread Machine Yeast is sufficient to raise 4 cups, approximately 1-pound, flour.

Hope this helps.
