Soaked Seed & Multigrain Sourdough Country Loaf
Hearty bakery multigrain sourdough loaded with a 20% toasted flax, sunflower, sesame, and pumpkin seed soaker and rolled in a crunchy seed coat
Soaked Seed & Multigrain Sourdough Country Loaf Baker's Formula & Schedule At A Glance
The Soaked Seed & Multigrain Sourdough Country Loaf is formulated at 78.0% apparent hydration (yielding 80.0% true total hydration once starter water and flour are factored in), featuring 75% Unbleached High-Protein Bread Flour / 15% Stoneground Whole Wheat Flour / 10% Stoneground Whole Dark Rye Flour, 20% active 100%-hydration levain, and 2.1% fine sea salt. Bulk fermented at 78°F (26°C) for 3.5–4.0 hours with lamination at Fold 2 + 3 coil folds, followed by 12–16 hrs cold retard @ 38°F (3°C), and baked at 450°F (232°C) Dutch Oven (22m covered / 22m uncovered so seeds toast golden). Including the 90g of carried water inside the hydrated inclusion raises Gross True Hydration to 96.6% (vs 80.0% free dough hydration).

Boundary Caveat: Static gram weights for Soaked Seed & Multigrain Sourdough Country Loaf assume 1 Seeded Country Loaf (1050g) at 78% apparent hydration (80% true hydration with 20% levain); if your pan volume, loaf count, or starter hydration differs from 100%, use the interactive gram scaler below to rebalance main flour and water automatically.
Dough Rheology & Handling Dynamics
Physics of gluten hydration, elasticity, and tackinessFlax and chia seeds exude water-binding mucilage gels when hydrated at a 1:1 ratio with boiling water. Pre-soaking the seeds ensures zero moisture theft from the 80.4% true hydration wheat-rye matrix while adding soluble fiber that keeps the crumb moist for a full week. Hydrological Accounting Note: Soaking the 90g 5-seed blend in 90g boiling water binds ~85g of water inside flax and chia mucilage gels (+16.1% seed-bound moisture), preventing dry seeds from stealing free hydration from the wheat gluten network.

Step-by-Step Artisan Method
Carefully curated instructions designed for consistency, oven spring, and blistering.
Build Active Sourdough Levain
Phase: Levain BuildMix 1 part mature sourdough starter with 2 parts lukewarm water (78°F / 26°C) and 2 parts unbleached flour to yield at least 96g active levain (20% inoculation). Ferment for 4–5 hours until doubled, domed, and buoyant.
Enzymatic Autolyse & Hydration
Phase: AutolyseCombine the 480g total flour blend (75% Unbleached High-Protein Bread Flour / 15% Stoneground Whole Wheat Flour / 10% Stoneground Whole Dark Rye Flour) with 337g filtered water (90% of formula water) in a broad mixing bowl. Mix until zero dry flour remains, cover, and rest for 45 minutes.
Incorporate Levain, Salt & Enrichments
Phase: Mixing & BassinageDimple 96g active levain, 10.1g fine sea salt (2.1%), and the reserved 37g bassinage water into the autolysed dough. Work using the Rubaud method or stand mixer for 4–6 minutes until smooth, incorporating any recipe enrichments.
Bulk Fermentation & Strength Folds
Phase: Bulk FermentationFerment at 78°F (26°C) for 3.5–4.0 hours with lamination at Fold 2 + 3 coil folds. Perform 3 to 4 sets of stretch-and-folds or gentle coil folds spaced 30–40 minutes apart during the first 2 hours, laminating any solid inclusions at the second fold.
Portioning, Pre-Shaping & Final Shaping
Phase: ShapingTurn the aerated dough onto the work surface to yield 1 Seeded Country Loaf (960g) (1 × 960g). Pre-shape gently, allow a 20-minute bench rest for gluten relaxation, then execute final shaping with taut surface skin tension.
Final Proofing & Cold Retardation
Phase: Proofing & RetardProof according to schedule: 12–16 hrs cold retard @ 38°F (3°C). Cold retardation at 38°F (3°C) slows yeast respiration while lactobacilli synthesize complex organic flavor compounds and organic acids.
Artisan Bake & Internal Cooling Cure
Phase: Bake & CureBake at 450°F (232°C) Dutch Oven (22m covered / 22m uncovered so seeds toast golden). Remove onto a wire cooling rack immediately after baking so bottom steam escapes cleanly, and allow starches to set before slicing.
Artisan Baker's Golden Rules for this Recipe
Account for True Total Hydration (80.0%): Because a 100%-hydration levain at 20% inoculation contributes equal parts water and flour, your true dough hydration is 2.0% higher than the 78.0% apparent water ratio.
Respect Desired Dough Temperature (DDT): Target 76°F–78°F (25°C–26°C) right after mixing so wild yeast and heterofermentative lactobacilli stay in optimal metabolic balance during 78°F (26°C) for 3.5–4.0 hours with lamination at Fold 2 + 3 coil folds.
Master the Handling Protocol: Delayed Lamination & Damp-Roll Crust Protocol: Never add seeds during initial mixing. Build full gluten strength for 60 minutes first, then stretch the dough on a wet counter and laminate the cooled seed soaker evenly across the sheet.
Verify Thermal Doneness: Bake at 450°F (232°C) Dutch Oven (22m covered / 22m uncovered so seeds toast golden) and always confirm core starch gelatinization with an instant-read thermometer before cooling on a wire rack.
Frequently Asked Questions & Troubleshooting
Q:What is the difference between 78.0% apparent hydration and 80.0% true hydration in this Soaked Seed & Multigrain Sourdough Country Loaf?
Apparent hydration (78.0%) only divides formula water (374g) by main flour (480g). True total hydration (80.0%) includes the 48g water and 48g flour inside your 96g sourdough levain, reflecting the real physical moisture of the dough.
Q:How can I scale this Soaked Seed & Multigrain Sourdough Country Loaf formula for multiple loaves or different pan sizes?
Use the live Baker's Percentage Calculator above: adjust Target Loaf Count or Target Unit Weight (default 1 × 960g = 960g batch) and every flour, water, levain, and salt gram weight recalculates automatically while preserving 78.0% hydration.
Q:Why does my dough feel stickier than expected during bulk fermentation?
Flax and chia seeds exude water-binding mucilage gels when hydrated at a 1:1 ratio with boiling water. Pre-soaking the seeds ensures zero moisture theft from the 80.4% true hydration wheat-rye matrix while adding soluble fiber that keeps the crumb moist for a full week. Ensure your flour meets the recommended protein spec and keep your hands lightly damp or oiled rather than adding raw bench flour.
Q:Can I cold-retard this dough longer in the refrigerator for deeper sourdough tang?
Yes! Keeping your refrigerator calibrated between 36°F and 38°F (2°C–3°C) puts wild Saccharomyces yeast into dormancy while lactic acid bacteria continue producing organic acids for up to 16–24 hours.
