What is a Poolish?
A poolish is a type of pre-ferment used in baking, primarily for bread. It's a simple mixture of flour, water, and a very small amount of yeast, typically with a 100% hydration ratio (equal parts flour and water by weight). This mixture is left to ferment for several hours, often overnight, before being incorporated into the final dough.
The primary purpose of using a poolish is to enhance the flavor, aroma, and texture of bread. The long, slow fermentation process allows the yeast and enzymes to break down starches and proteins in the flour, producing complex flavors and organic acids. This results in a bread with a more open crumb structure, a crispier crust, and an extended shelf life.
Who Should Use a Poolish?
- Home Bakers: Looking to elevate their bread-making beyond basic recipes.
- Artisan Bakers: Seeking to impart depth of flavor and unique textures to their loaves.
- Anyone: Who wants to improve the keeping qualities of their bread.
Common Misunderstandings about Poolish
A common misunderstanding is confusing a poolish with a sourdough starter or a biga. While all are pre-ferments, a poolish uses commercial yeast and is typically 100% hydration, resulting in a pourable batter-like consistency. A sourdough starter uses wild yeast and bacteria, while a biga is a much stiffer pre-ferment, often with a lower hydration (around 50-60%). The "poolish calculator" helps clarify the precise ratios needed for this specific pre-ferment.
Poolish Calculator Formula and Explanation
Our poolish calculator uses standard baker's percentage principles to break down your total recipe into poolish components and final dough additions. All percentages are relative to the "Total Flour for Final Dough" unless otherwise specified.
Key Formulas:
- Poolish Flour:
Total Flour for Final Dough × (Poolish Flour % / 100) - Poolish Water:
Poolish Flour × (Poolish Hydration % / 100) - Poolish Yeast:
Poolish Flour × (Poolish Yeast % / 100) - Total Recipe Water:
Total Flour for Final Dough × (Total Dough Hydration % / 100) - Remaining Water:
Total Recipe Water - Poolish Water - Remaining Flour:
Total Flour for Final Dough - Poolish Flour - Remaining Salt:
Total Flour for Final Dough × (Total Dough Salt % / 100) - Remaining Additional Yeast:
Total Flour for Final Dough × (Total Dough Additional Yeast % / 100)

Practical Examples Using the Poolish Calculator
Let's walk through a couple of examples to demonstrate how to use this poolish calculator effectively and understand its outputs.
Example 1: Classic Baguette Poolish (Metric)
You want to make baguettes with 500g total flour. You plan for a 30% poolish at 100% hydration, using 0.1% yeast (of poolish flour). Your final dough should have 75% hydration, 2% salt, and no additional yeast.
Inputs:
- Total Flour: 500g
- Poolish Flour %: 30%
- Poolish Hydration %: 100%
- Poolish Yeast %: 0.1%
- Total Dough Hydration %: 75%
- Total Dough Salt %: 2%
- Total Dough Additional Yeast %: 0%
- Fermentation Temperature: 21°C
- Fermentation Time: 12 hours
Results (using the poolish calculator):
- Total Poolish Weight: 300.15g
- Poolish Flour: 150g
- Poolish Water: 150g
- Poolish Yeast: 0.15g
- Remaining Flour: 350g
- Remaining Water: 225g (375g total water - 150g in poolish)
- Remaining Salt: 10g
- Remaining Additional Yeast: 0g
This tells you to mix 150g flour, 150g water, and 0.15g yeast for your poolish. For the final dough, you'll combine the poolish with 350g fresh flour, 225g water, and 10g salt.
Example 2: High Hydration Sourdough-Style Bread with Poolish (Imperial)
You're aiming for a large loaf using 1.5 lbs of total flour. You decide on a 25% poolish at 90% hydration, with 0.05% yeast (of poolish flour). The final dough will be 80% hydration overall, 2.2% salt, and a tiny bit of additional yeast (0.05%).
Inputs:
- Total Flour: 1.5 lbs (approx. 680g)
- Poolish Flour %: 25%
- Poolish Hydration %: 90%
- Poolish Yeast %: 0.05%
- Total Dough Hydration %: 80%
- Total Dough Salt %: 2.2%
- Total Dough Additional Yeast %: 0.05%
- Fermentation Temperature: 70°F
- Fermentation Time: 14 hours
Results (using the poolish calculator, converted to Imperial):
- Total Poolish Weight: ~0.65 lbs (10.4 oz)
- Poolish Flour: ~0.38 lbs (6 oz)
- Poolish Water: ~0.34 lbs (5.4 oz)
- Poolish Yeast: ~0.0002 lbs (0.003 oz)
- Remaining Flour: ~1.12 lbs (17.9 oz)
- Remaining Water: ~0.75 lbs (12 oz)
- Remaining Salt: ~0.03 lbs (0.47 oz)
- Remaining Additional Yeast: ~0.0007 lbs (0.01 oz)
This example highlights the importance of the unit switcher in the poolish calculator for imperial bakers. Note that small yeast amounts might be difficult to measure precisely without a jeweler's scale.

Key Factors That Affect Your Poolish
Understanding these factors is crucial for successful poolish usage and getting the most out of your poolish calculator results:
- Fermentation Temperature: This is perhaps the most critical factor. Higher temperatures (e.g., 24°C / 75°F) accelerate yeast activity, leading to a faster poolish ready in 4-6 hours. Lower temperatures (e.g., 18°C / 65°F) slow down fermentation, extending the time to 12-18 hours, which often develops more complex flavors. Our poolish calculator provides a guide for this.
- Yeast Percentage: The amount of yeast directly impacts fermentation speed. A tiny amount (0.05-0.1% of poolish flour) is typical for long, slow ferments. Increasing this will shorten the fermentation time significantly.
- Flour Type: Different flours absorb water differently and have varying protein contents. Stronger flours (higher protein) can handle longer fermentation, while weaker flours might degrade too quickly. The poolish calculator assumes a general-purpose flour.
- Hydration Level: While 100% hydration is classic, a slightly lower (e.g., 90%) or higher (e.g., 110%) hydration will affect the poolish's consistency and yeast activity. A wetter poolish ferments slightly faster.
- Fermentation Time: The duration is key. An under-fermented poolish won't contribute much flavor, while an over-fermented one can lead to a soupy, acidic pre-ferment that negatively impacts dough structure. Look for a domed surface with small bubbles and a slightly collapsed center as indicators of readiness.
- Salt: Salt is typically *not* added to the poolish itself as it inhibits yeast activity. It's added later with the final dough ingredients. This is why our poolish calculator only assigns salt to the remaining dough ingredients.
Frequently Asked Questions (FAQ) about Poolish
Q1: What's the ideal hydration for a poolish?
A: The classic poolish is made with 100% hydration, meaning equal parts flour and water by weight. This creates a very wet, batter-like consistency, which is ideal for yeast activity and flavor development. Our poolish calculator defaults to 100% for this reason.
Q2: Can I use different types of flour for my poolish?
A: Yes, you can. All-purpose flour or bread flour are common choices. Using a portion of whole wheat or rye flour can add different flavor notes, but be aware they absorb water differently and might affect fermentation speed. Adjusting the "Poolish Hydration %" in the poolish calculator can compensate for this.
Q3: How do I know when my poolish is ready?
A: A ready poolish will be very bubbly, have a domed surface, and often start to show a slight collapse or cratering in the center. It should smell pleasantly yeasty and slightly alcoholic. If it's completely deflated and smells strongly acidic, it might be over-fermented.
Q4: What if the "Remaining Water" result is negative?
A: A negative "Remaining Water" means the water contributed by your poolish alone is more than the total water required for your final dough's desired hydration. This is uncommon with standard recipes. You'll need to either increase your "Total Dough Hydration %" or decrease your "Poolish Hydration %" in the poolish calculator to get a positive remaining water amount.
Q5: Can I prepare my poolish in advance and store it?
A: Yes, you can. Once your poolish is mature, you can retard its fermentation by placing it in the refrigerator for up to 24-48 hours. Bring it back to room temperature for 30-60 minutes before mixing into your final dough. This flexibility is a great benefit when using a poolish calculator for planning.
Q6: How does using a poolish affect the overall baking process?
A: A poolish adds an extra step to your baking schedule, but it significantly improves flavor and texture. It also reduces the amount of yeast needed in the final dough, as the poolish contributes a vibrant yeast culture. The dough will generally be easier to handle and develop gluten more readily.
Q7: What's the difference between a poolish and a biga?
A: Both are pre-ferments using commercial yeast. The key difference is hydration: a poolish is typically 100% hydration (liquid, batter-like), while a biga is much stiffer, usually 50-60% hydration (firm dough). The poolish calculator focuses specifically on the former's characteristics.
Q8: Why is temperature important for poolish fermentation?
A: Temperature profoundly influences yeast activity. Warmer temperatures speed up fermentation, while cooler temperatures slow it down, allowing for longer flavor development. Consistency in temperature ensures predictable results. Our poolish calculator includes temperature as a key input for accurate planning.
