- What is baker's percentage and why do professional bakers use it?
- Baker's percentage (also called baker's math) expresses every ingredient as a percentage of the total flour weight. Flour is always 100%, so if a recipe uses 620g of water for 1000g of flour, water is at 62%. This system makes scaling any recipe trivial — multiply or divide all percentages by the same batch factor. Italian artisan bakers and pizzamakers universally use this method because it works regardless of batch size, from a home loaf to a 50kg professional batch.
- How do I convert a regular recipe into baker's percentages?
- Divide each ingredient weight by the total flour weight and multiply by 100. Example: 650g water ÷ 1000g flour × 100 = 65% hydration. Do the same for salt, yeast, oil and any other ingredient. Once you have the percentages, you can scale the recipe to any batch size by multiplying the percentages by your new flour weight in kilograms. The calculator automates this conversion for you.
- What are typical baker's percentages for Italian bread and pizza?
- Standard Italian benchmarks: Pizza Napoletana 58–62% water, 2.5% salt, 0.1–0.3% fresh yeast; pizza in teglia 75–85% water; ciabatta 80–85%; focaccia Genovese 70–75%, 2–3% salt, 3–4% olive oil; Pane di Altamura (semolina) 65% water; pane Pugliese 65–70%. Salt ranges from 1.8–2.8% depending on region and bread type. Yeast drops dramatically for long cold fermentation — Napoletana at 24h uses as little as 0.05% fresh yeast.
- Why doesn't baker's math add up to 100% like a regular percentage?
- Baker's percentages are not proportional shares of the total batch weight — they are ratios relative to flour only. This means they can exceed 100% in total (a 75% hydration dough has flour 100% + water 75% + salt 2.5% = 177.5% total). This is intentional and is what makes the system so powerful: the flour anchor stays constant, making mental arithmetic and scaling much easier than working with weight fractions of the total dough.
- How does hydration percentage affect dough handling?
- Below 65%: stiff, easy to handle, tight crumb — classic Neapolitan pizza, traditional loaf bread. 65–75%: moderate stickiness, good for most artisan breads, focaccia. Above 75%: very sticky, requires stretch-and-fold technique instead of kneading, produces an open irregular crumb (ciabatta, teglia). Professional Italian bakers usually start at 65% and gradually increase hydration as their handling skills improve. Temperature also matters — warmer dough absorbs less water effectively.
- What happens if I add too much salt in baker's percentage terms?
- Salt above 3% starts to significantly inhibit yeast activity and tighten gluten, slowing fermentation. The Italian standard is 2–2.5% for pizza and 1.8–2% for most bread. Focaccia and Pane di Altamura often go to 2.5–3% for flavour. Salt should always be added after the initial mix — never directly onto dry yeast — to avoid killing the yeast cells. In professional production, salt is added in the last few minutes of mixing.
