Why bake with Platinum® Instant Sourdough: Yeast + Sourdough Culture? Platinum® Yeast’s unique formula blended with a real dried sourdough starter provides a variety of benefits!
Benefits of Baking with Platinum® Instant Sourdough:
- No need to maintain a sourdough starter. This yeast product is already blended with a dried sourdough culture, so you don’t have to!
- Adds a real sourdough flavor to any yeast recipe.
- Contains a premium instant yeast, giving a consistent rise to all your baked goods. Plus, there’s no need to proof the yeast; simply add it to your flour and other dry ingredients.
- Added dough improver provides tolerance to the dough if it is under-kneaded or over-proofed and extends the freshness shelf life of your baked goods.
Platinum® Instant Sourdough adds real sourdough flavor to ANY yeast recipe that calls for one (0.25 ounce) packet or 2 ¼ teaspoons of dry yeast (active or instant). No need to maintain a sourdough starter!
It truly is real sourdough made easy!
When Should You Use Platinum® Instant Sourdough: Yeast + Sourdough Culture?
Use Platinum Instant Sourdough to add real sourdough flavor to your favorite yeast bread recipes.
Only use a full packet of Platinum Instant Sourdough to get the correct amount of yeast and flavor. Simply substitute one full packet for one (0.25 ounce/7 gram) packet or 2 ¼ teaspoons of dry (active or instant) yeast.
When used in place of a standard (0.25 ounce/7 gram) packet of dry yeast in any of your favorite yeast recipes, Platinum® Instant Sourdough adds a mild sourdough flavor to the final baked good.
IMPORTANT USAGE NOTES:
- Since the packet contains a blend of yeast and dried sourdough starter, only full packets of Platinum® Instant Sourdough should be used in recipes.
- A full packet must be used. Use one full packet in place of one standard (0.25-ounce/7-gram) packet or 2 ¼ teaspoons of dry (instant or active dry) yeast. Only full packets should be used.
- Platinum® Instant Sourdough is NOT intended to be used in place of a sourdough starter in a traditional sourdough recipe that calls for a sourdough starter. Use it to replace active dry or instant yeast in a recipe.
How to Use Platinum® Instant Sourdough
- Simply substitute one full packet of Platinum® Instant Sourdough for one (0.25 ounce/7 gram) packet or 2 ¼ teaspoons of any dry yeast in any recipe.
- Follow the recipe instructions or blend Platinum® Instant Sourdough with dry ingredients.
- Add very warm liquid — make sure it’s not too hot to touch. Suggested temperature range: 120˚F to 130˚F.
One packet of Platinum® Instant Sourdough will raise up to 4 cups (about 1 pound) of flour.

Be good to your yeast, and it will perform well in your bread! Don’t forget that yeast is a living organism, and its freshness and shelf life are dependent on how the yeast is stored. Dry yeast will lose its leavening power if exposed to air, moisture or heat, even when it is still in a sealed jar or package. Learning the correct way to store your yeast will keep it fresher longer.
Shelf Life Information
