Converting High-Yeast 14g (2 Packets) Active Dry Yeast to Sourdough Levain in 1000g Flour
High-inoculation conversion math comparing 160g direct yeast equivalency vs. 200g (20% baker's math) for 1000g flour recipes.
Here is the conversion in one line for a 1000g flour and 700g liquid dough built with 14g (2 Packets) active dry commercial yeast: 160g of ripe 100% hydration starter, deducted from the main mix as 80g flour and 80g water, giving 920g and 620g. Standard 20% baker's math on the same 1000g base wants 200g of starter and 900g / 600g.

Yeast-to-Sourdough Conversion Table: 14g Active Dry Yeast on a 1000g Base
Starter hydration shifts the deduction asymmetrically: a stiffer levain carries more flour and less water per gram.
| Starter Hydration | Packet-Equivalent Starter (Deductions) | Adjusted Main Dough (Packet Mode) | 20% Artisan Starter (Deductions) | Adjusted Main Dough (20% Mode) |
|---|---|---|---|---|
| 100% starter on 500g [Exact Target] | packet mode 160g | main 420g / 270g | 20% mode 100g | main 450g / 300g |
| 50% starter on 1000g Alt Row A | packet mode 160g | main 893.3g / 646.7g | 20% mode 200g | main 866.7g / 633.3g |

Balancing Osmotic Stress & Hydration When Replacing 14g Active Dry Yeast in 1000g Flour
Inoculation rate, not yeast weight, sets the fermentation clock. Converting 14g of active dry yeast by packet equivalency on a 1000g base yields an effective inoculation of 16%, which is why the bulk window can stretch well past the 4.0 â 5.5 hours at 76°F (24°C) quoted for standard 20% inoculation.
Keep a log. The most useful column is not the starter weight but the total elapsed time from mixing to shaping, because on the second and third bake the 1000g formula with 160g of levain is a different dough to the one you remember.
3-Step Conversion Checklist (14g Active Dry Yeast â Sourdough in 1000g Flour)
- Weigh Active Levain (200g or 160g): Measure 200g peaked 100% starter for 20% inoculation, or 160g for direct 14g Active Dry Yeast equivalency.
- Deduct Main Flour & Liquid (1000g Base): Scale main grain to 900g (-100g) and liquid to 600g (-100g).
- Ferment for 4.0 â 5.5 hours at 76°F (24°C): Hold the 1000g dough at 75°Fâ78°F until +50% volumetric expansion before shaping and cold proofing.
- Retard and Bake: Cold-proof the shaped dough for 12â16 hours at 38°F, then bake covered and uncover to a deep mahogany crust.
Diagnostic Answers: Replacing 14g (2 Packets) Active Dry Yeast w
Does the type of commercial yeast change the starter weight?
Yes. Active Dry Yeast has its own potency per gram, so 14g of it converts to 160g of sourdough culture rather than the 200g that the 20% rule would prescribe on a 1000g base.
Can I use a 50% hydration levain when converting 14g of Active Dry Yeast?
Yes, but the deduction changes: 160g at 50% hydration holds 107g grain and 53g water, so deduct those two figures instead.
How much longer does sourdough take to rise than 14g of Active Dry Yeast?
Expect bulk fermentation on a 1000g flour batch to take 4.0 â 5.5 hours at 76°F (24°C), roughly 3 to 4 times longer than commercial active dry yeast.
