Sourdough Panettone — Hydration Guide
Target 50%. Workable range 45–55%.
Why this hydration for Sourdough Panettone?
Panettone is the Italian Christmas enriched bread — dramatically high in butter (40%), eggs (35%), sugar (25%), candied fruit (30%). Requires lievito madre (stiff 50% hydration sourdough) for 48-72 hours of complex multi-stage fermentation. Advanced-level baking — extremely butter/fat-laden dough tests gluten development. Traditionally proofed in paper panettone molds that support the final dome shape. Invert while cooling to prevent collapse.
Flour mix: 100% bread flour.
What 50% hydration does for Sourdough Panettone
At its 50% target, Sourdough Panettone bakes up with a tight, tender, even crumb that slices cleanly — the low water keeps the dough firm and structured rather than open. That's why the style sits where it does on the scale — push it much drier and it tightens toward a sandwich loaf; push it much wetter and it slackens past what the enriched structure can hold.
Worked water math for a 500 g batch
| Flour | 500 g (100%) |
| Water | 250 g (50%) |
| Salt | 6 g (1.2%) |
| Levain | 150 g (~30%) |
The levain already carries some of that flour and water. The calculator below subtracts its contribution so the numbers you actually weigh at the bench hit 50% exactly.
How this flour mix drinks
Sourdough Panettone uses 100% bread flour. That's straight white bread flour, which handles predictably at 50% — add all the water up front and adjust only if a new bag of flour behaves differently.
Technique at 50%
Stage 1 dough: flour, water, levain, sugar, egg yolks — develop gluten in mixer 15 min, let ferment 8h. Stage 2: add butter gradually, then candied fruit, raisins, vanilla, zests. Additional 10 min mixing. Short 3h bulk. Shape into ball, place in panettone mold. Proof 10-12h until dome rises 1 inch above rim. Cut cross in top with butter, bake 330°F for 50-55 min until internal 208°F. Immediately invert, cool hanging upside-down for 4+ hours (prevents compression).

How the math works
Total water = flour × hydration %. Your levain contributes 50 g flour + 50 g water — both count toward the totals. You add only the remainder as fresh flour and water.
Salt % is computed on total flour weight, not final-dough flour.
Sourdough Panettone hydration — FAQ
What hydration is Sourdough Panettone meant to be?
Target 50% — that's 50 g of water per 100 g of flour by weight. The workable range is 45–55% depending on your flour and handling skill.
How much water do I need for Sourdough Panettone?
Multiply your flour weight by 0.5. For a 500 g flour batch that's 250 g water, plus about 6 g salt (1.2%). The calculator on this page also subtracts the water your levain already contributes.
Can I make Sourdough Panettone at a lower hydration?
Down to about 45% gives a tighter crumb and much easier, less sticky handling — a good starting point if you're new to this style. Below 45% the open, characteristic Sourdough Panettone texture is largely lost.
Can I make Sourdough Panettone at a higher hydration?
Up to about 55% opens the crumb further but demands confident wet-dough handling (more folds, a well-floured bench, decisive shaping). Above 55% the structure usually slackens and the loaf spreads instead of rising.
