ℹ️ What is autolyse?

A pre-mix rest of just flour + water (no salt, no levain) that allows flour to fully hydrate, activates enzymes, and develops gluten passively — reducing mix time and improving extensibility.

How yeast conversion works

Fresh : Active Dry : Instant = 3 : 1.5 : 1 by weight. Fresh yeast has the highest moisture content (~70%). Instant yeast is most concentrated and can be added directly to flour without rehydrating.

Sourdough starter is a live culture of wild yeast and bacteria in flour + water. You need 35–50g of 100% hydration starter to replace 1g of instant yeast. The range reflects starter activity: a vigorous freshly-fed starter sits at the lower end; a sluggish or cold starter needs more.

Why weight beats volume in baking

Volume is inconsistent; weight is exact. Scooping flour compresses it — a carelessly packed cup can weigh 50g more than a sifted one. A gram is always a gram. Professional bakers and King Arthur Baking publish ingredient weights because they produce consistent results every time.

Millilitre conversions for dry ingredients are marked with ~ (approximate) because volume-by-density assumes ideal packing. The ml figure is a useful estimate, not a precise measure.

Vital Wheat Gluten

Boost weak flour to bread-flour strength

AP: ~10–11%, bread: 12–14%
Strong dough: 12–14%, high-hydration: 14–16%

What is vital wheat gluten?

Vital wheat gluten (VWG) is a dry powder extracted from wheat — approximately 75% pure gluten protein. Adding it to weaker flours raises protein content, giving dough more strength, extensibility, and structure.

When to use it: upgrading plain flour for bread baking; strengthening whole grain flours (rye, spelt) which have weak gluten; high-hydration doughs needing more structure.

Caution: More than ~5% baker's % (50g per 1kg flour) can make dough tough and inelastic. Use the minimum needed to reach your target.

The preferment calculator for
poolish, biga, and pâte fermentée

The preferment calculator above takes your total flour weight and target preferment percentage, then calculates the exact flour, water, and yeast quantities for your chosen preferment type. It also adjusts the final dough ingredients so the overall formula stays balanced.

A preferment is a portion of your dough mixed ahead of time and left to ferment before being folded into the main mix. That extra fermentation time builds flavour compounds, organic acids, and enzymatic activity that you simply cannot replicate in a same-day dough. The result is a deeper, more complex flavour and a loaf that stays fresh noticeably longer.

Poolish gives you an open, blistered crust with mild acidity. Biga produces a slightly denser crumb with a sweeter, more complex character. Pâte fermentée is essentially a piece of yesterday's dough held back, adding body and mild tang with minimal extra work. Each suits different bread styles and baking schedules.

Frequently Asked

Questions about
preferments and pre-ferments

What is a preferment and why use one?
A preferment is a portion of the dough mixed in advance and left to ferment before being incorporated into the main dough. It builds flavour, extends shelf life, and improves crust colour and crumb structure. Common preferments include poolish (equal weights of flour and water with a small amount of yeast), biga (stiffer, Italian-style, typically 50 to 60% hydration), and pâte fermentée (a piece of dough held back from a previous bake). Each produces a distinct flavour profile and texture.
What is the difference between poolish and biga?
Poolish is a wet preferment at 100% hydration, meaning equal weights of flour and water. It produces a light, open crumb with mild acidity and a caramelised crust. Biga is a stiff Italian preferment, typically 50 to 60% hydration. The lower water content slows fermentation, producing a more complex, slightly sweeter flavour with an irregular open crumb. Biga is associated with ciabatta and Italian breads. Poolish is more common in French-style breads and baguettes.
How much preferment should I use in a recipe?
Most recipes use between 20% and 40% preferment as a proportion of total flour weight. Lower percentages give a subtler flavour contribution and a longer final fermentation. Higher percentages produce more complex, tangy flavour and a slightly shorter overall fermentation time for the main dough. The DoughRise preferment calculator lets you set your target percentage and calculates exact quantities alongside the adjusted final dough ingredients.
