Wheat-rye sourdough calculator
The everyday Polish loaf on zakwas: 80% wheat, 20% rye, a firm dough and a gentle sourness.
Chleb pszenno-żytni — the everyday Polish loaf: wheat-dominant with a rye share, on zakwas, with a tight crumb and a gentle sourness. This is the daily bread of Polish bakeries, per the trusted Moje Wypieki formula: 80/20 flours and a full 50% dose of starter.
How it works
The blend and the big zakwas
The base splits 80% wheat bread flour and 20% rye. The leavening is a generous 50% of active wheat zakwas — half a kilo per kilo of flour — which is what gives the loaf its recognizable, mild tang on a manageable schedule.
A firm dough by design
Added water is only 48% of flour — with the zakwas counted the whole dough sits near the upper 50s. This is deliberately stiffer than French-style loaves: the target is a tight, springy crumb that holds butter and ham.
Proofing and baking
Knead well, bulk about 90 minutes with a fold, shape two loaves (~980 g each) into baskets or pans, and give a final hour of proof. Bake hot with steam, starting around 250 °C and dropping — a Polish loaf wants real crust color.
Sources & methodology
Every percentage in this calculator traces to the published sources below — nothing is invented. Where respected sources disagree, the default sits inside the documented range.
- Moje Wypieki — chleb pszenno-żytni (przepis czytelniczki) — The chosen everyday loaf — a reader’s recipe in the site’s user section, not the author’s own: 80/20 wheat–rye, ~48% added water, 50% wheat starter (the family spans 60:40 to 84:16).
FAQ
What about chleb baltonowski?
The canonical Polish shop loaf is a cousin with a distinctive twist: it runs closer to 60/40 wheat-rye and combines a rye zakwas build with a small parallel yeast preferment. Same family; this calculator follows the simpler pure-zakwas home formula.
Why is the dough so firm compared to my other sourdough?
Because the style demands it: Polish everyday bread has a dense, even crumb, not open holes. Extra water produces a flatter loaf with the wrong texture.
Can I change the wheat-to-rye ratio?
The family spans roughly 60:40 to 84:16 across respected sources. More rye means a moister, denser, more aromatic loaf — adjust the composition and expect the dough to get stickier as rye grows.
