{"schema":"askedwell-earned-page-v1","url":"https://askedwell.com/pages/what-ratio-of/sourdough-hydration","question":"What is the right hydration ratio for sourdough bread?","short_answer":"Standard sourdough hydration is 70–80% (water-to-flour weight). Beginners: 65–70% (easier to handle). Open-crumb artisan: 75–85%. Above 85% (high-hydration / \"ciabatta-style\"): requires advanced technique.","long_answer":"Hydration is the ratio of water to flour in dough, expressed as a baker's percentage (water weight ÷ flour weight × 100). Sourdough hydration affects everything: texture, crumb structure, flavor, ease of handling, and bake time.\n\n**Standard sourdough hydration ranges:**\n\n**Low hydration (60–68%):**\n- Easier to shape + score\n- Dense, tight crumb\n- Good for beginners + breakfast loaves\n- Examples: Tin loaves, sandwich bread, pain de mie\n\n**Standard hydration (70–75%):**\n- Balanced texture + flavor\n- Workable for most home bakers\n- Slightly open crumb\n- Examples: Most country loaves, classic sourdough boules, Ken Forkish-style breads\n\n**High hydration (75–85%):**\n- Open-crumb \"artisan\" sourdough\n- Requires good technique (stretch + fold, no kneading)\n- Wet, sticky dough — challenging to shape\n- Examples: Tartine-style, ciabatta-style, focaccia\n- Modern artisan bakery standard\n\n**Very high hydration (85%+):**\n- \"Liquid dough\" texture\n- Requires bench scraper for handling\n- Extreme open crumb (large irregular holes)\n- Long ferments at low temperatures\n- Examples: Some Italian ciabattas, modern croissant variants\n\n**Why hydration affects texture:**\n- Water enables gluten development (stretchy network)\n- More water = more gluten extensibility (stretchier dough)\n- More water = larger CO2 bubbles trapped → more open crumb\n- More water = stickier dough (harder to handle)\n\n**Calculating hydration:**\n- Total water (grams) ÷ Total flour (grams) × 100 = Hydration %\n- Example: 750g water + 1000g flour = 75% hydration\n- Note: includes ALL water sources (starter water, milk if used, eggs counted as 75% water by weight)\n- Doesn't include flour from starter (starter's flour adds to total flour)\n\n**Standard starter hydration:**\n- 100% hydration starter (1:1 flour:water): industry standard\n- 60–80% hydration \"stiff\" starter: more sour, slower fermentation\n- 120% hydration \"liquid\" starter: less sour, faster\n\n**How hydration affects fermentation timing:**\n- Higher hydration → faster bulk fermentation (more accessible water for yeasts)\n- 65% bulk: 4–6 hours at 75°F\n- 75% bulk: 3–5 hours at 75°F\n- 85% bulk: 2–4 hours at 75°F\n\n**The \"do you have flour for this?\" reality:**\n- Bread flour (12-13% protein): handles 75-85%\n- All-purpose flour (10-12% protein): max 75%\n- 00 flour (Italian, low gluten): 65-70% best\n- Whole wheat: less hydration capacity due to bran absorbing differently; 70% for whole wheat usually equivalent to 75% white\n\n**The \"open crumb\" obsession:**\n- Big open holes correlate with high hydration BUT also depend on shaping technique\n- Tight tension shaping creates small even crumb (sandwich loaf)\n- Gentle shaping creates open crumb (artisan boule)\n- Hydration alone doesn't guarantee open crumb; technique matters as much\n\n**Don't:**\n- Increase hydration without adjusting technique (need stretch-and-fold instead of kneading)\n- Use water at room temp for high-hydration dough (use cooler water — dough warms during work)\n- Skip the bench rest (high-hydration needs more time to relax)\n- Add water mid-process (won't incorporate properly)\n\n**Cross-reference:** see /pages/how-long-does/sourdough-rise for the timing side + /pages/how-long-does/pizza-dough-rise for similar high-hydration considerations.\n\nMost published references (Ken Forkish \"Flour Water Salt Yeast\", Chad Robertson \"Tartine Bread\", Maurizio Leo \"The Perfect Loaf\", Jeffrey Hamelman \"Bread\") converge on 70-80% as the standard home-baker range, with 85%+ for advanced applications.","duration_iso":"PT0M","ranges":[{"condition":"Beginner loaves + tin breads","duration":"60–68% hydration"},{"condition":"Standard country loaves","duration":"70–75% hydration"},{"condition":"Artisan open-crumb sourdough","duration":"75–85% hydration"},{"condition":"Very high (Tartine-style or ciabatta)","duration":"85%+ hydration"},{"condition":"Recommended for beginners","duration":"70% (1000g flour : 700g water)"}],"variables":[{"name":"Flour protein content","effect":"Higher protein (bread flour 12-13%) holds more water;

Don't jump straight to 80%+ without technique foundation."},{"question":"How do I increase hydration without ruining my dough?","answer":"Increase by 2-3% per attempt, not 10%. Adjust technique: more stretch + folds (every 30 min), longer bulk, slightly cooler water. Watch the dough — if it's breaking down, hydration jumped too much."},{"question":"Why is open crumb so prized?","answer":"Open crumb is the visual signature of well-fermented + properly-handled high-hydration bread. It indicates: (1) good fermentation (CO2 produced enough), (2) good shaping (didn't compress), (3) right hydration (water enabled large bubbles).
