weight of yeast

From the Red Star web site, 1 packet of active dry yeast is typically 1/4 oz (7.1g)

1 package is usually 2-1/4 teaspoons, but not exactly.

Good to know for conversion of volumetric recipes.

Other interesting things I learned about ADY on the Red Star site:

1. Active Dry Yeast can be added directly to dry ingredients! Use liquid temperatures of 120°F-130°F. Yeast activity may decrease if it comes into direct contact with salt or sugar.
2. If dissolving ADY, add to 110°F-115°F water.

yeast amounts

From Daniel DiMuzio's "Bread Baking: An Artisan's Perspective"

This applies to instant yeast in a lean dough, at 77F, for rising times during bulk fermentation

• 0.3% - 3-4 hours
• 0.4 - 0.5% - 1.5 to 2 hours
• 0.7% - 1 hour
• 1% - 30 to 45 min
