How I Actually Use a Bread Making Planner

A bread making planner is just a structured way to track every variable in your dough before you ever mix a single ingredient. The ones I see most people using are Google Sheets templates with baker's percentages, hydration targets, autolyse windows, bulk fermentation timers, and bake schedules laid out in one place. It sounds tedious until you've lost three loaves to under-fermented dough because you forgot to account for a warm kitchen, and then it becomes the only thing standing between you and an edible result. My setup lives in Google Sheets. Columns include flour weight, water weight, salt percentage, starter percentage, total hydration, autolyse duration, bulk fermentation time, bulk fermentation temperature estimate, fold schedule, proofing time, and bake time with lid on versus off. The row structure is simple: one row per recipe variant, and you can clone it when you tweak something. The real value shows up when you have five versions of the same formula in front of you and need to remember which one rose too fast on Tuesday. I calculate hydration as total water divided by total flour, including the water already present in the starter. That detail matters more than people admit. A 20% starter at 100% hydration contributes water that most calculators ignore, which pushes your effective hydration up by about 1-2 percentage points. Most spreadsheets don't factor that in automatically unless you build it in yourself.

Here's a breakdown of the exact formula columns I use: Total flour (grams): This is the sum of flour from the main dough and flour from the starter. If your starter is 100g at 100% hydration, that's 50g flour and 50g water. Total water (grams): Main dough water plus water from the starter. Same example above gives you 50g water from the starter.

Hydration percentage: Total water divided by total flour, expressed as a percentage. At 76% hydration, your dough will feel quite soft and sticky during bulk but should hold its shape after folds. Salt percentage: Standard range is 1.8% to 2.2% of total flour weight. I use 2% consistently because it controls fermentation without over-salting the crust. Starter percentage: Usually 15% to 25% of total flour weight for sourdough. I settled on 20% because it gives reliable rise without making the tang overpowering.

Autolyse time: Ranges from 30 minutes for high-hydration doughs to 2 hours for dense whole grain blends. Longer autolyse develops gluten structure before any salt or starter touches the flour. Bulk fermentation window: This is the hardest column to nail down. It depends on ambient temperature, starter activity, and flour protein content. At 75°F room temperature, a 76% hydration dough typically needs 4 to 5 hours. At 68°F, that stretches to 6 or 7 hours. Write down the actual time each batch takes and you'll start seeing patterns within a month. Fold schedule: I do four sets of coil folds at 30-minute intervals during the first two hours of bulk, then switch to stretch and folds every 45 minutes until the dough passes the windowpane test. The spreadsheet row tracks how many sets I completed and how the dough responded.

Proofing time: This splits into bench rest plus final proof. Bench rest is usually 30 to 45 minutes after dividing and pre-shaping. Final proof can be room temperature for 1 to 2 hours or retarded in the refrigerator for 12 to 16 hours. The planner row notes which method I chose and why. Bake time: Dutch oven method is 20 minutes covered at 500°F followed by 20 minutes uncovered at 475°F. Open sheet pan baking requires a different approach—500°F with steam for 15 minutes, then 450°F for another 25 minutes without steam. I record oven spring height, crust color on a scale of 1 to 5, and crumb openness after cooling. The counter-intuitive part nobody mentions is that bulk fermentation time matters less than you think if you're doing cold retard. A dough that ferments for only 3 hours at room temperature but then sits in the fridge for 14 hours will often develop better flavor and structure than one that bulk ferments for 6 hours straight. The cold slows enzyme activity and allows starches to break down more gradually. I learned this the hard way when I accidentally pulled a batch from the fridge after 18 hours instead of 14 and got a loaf with deeper flavor but slightly denser crumb than usual. The spreadsheet logged both batches and the difference was clear.

Another detail beginners consistently mess up is the relationship between starter feeding schedule and bulk timing. If your starter was fed 8 hours ago at room temperature, it's at peak activity and your bulk will move fast. If it was fed 24 hours ago, it's past peak and your bulk will crawl. I now add a column for hours since last feed and cross-reference it with bulk time. A 6-hour-old starter at 75°F might need only 3 hours of bulk. A 20-hour-old starter under the same conditions might need 7 hours. That single column cut my wasted loaves in half over three months. Here's the practical problem I ran into that made me redesign my entire planner. I tried using a standard sourdough template for a 32% hydration pretzel dough and the fermentation estimates were completely wrong. The template assumed 76% hydration behavior, so it called for 5 hours of bulk. My pretzel dough sat for 5 hours and was barely alive. Low-hydration doughs ferment slower because there's less free water for yeast and bacteria to move through. I added a hydration modifier column that adjusts bulk time downward for every 5 percentage points below 70% hydration. That fixed the pretzel issue and also improved my bagel and focaccia calculations. I built the hydration modifier by tracking 12 different dough types over six months. The average correction factor came out to about 15% less bulk time per 5% hydration drop below 70%. It's not a perfect rule, but it's close enough to stop guessing. Doughs above 80% hydration need the opposite adjustment—roughly 10% more bulk time per 5% increase.

Downloadable templates exist everywhere, but most of them share the same blind spots. They assume room temperature fermentation, they ignore starter age, and they treat all flours the same. A whole wheat flour absorbs more water and ferments slower than bread flour at the same hydration percentage. I modified my sheet to include a flour type multiplier. Bread flour gets 1.0, whole wheat gets 1.15, rye gets 1.3. Those multipliers extend the bulk time estimate to account for bran cutting gluten strands and slowing yeast movement. The planner I use now has about forty columns because I stopped trying to simplify it down to something pretty. Each column represents a variable I've learned to track because ignoring it cost me a loaf. The core columns stay the same, but I add rows for special cases like high-hydration ciabatta, enriched brioche dough, or no-knead cold ferment. Brioche at 65% hydration behaves differently than a lean dough at 65% hydration because the butter coats flour proteins and slows gluten development. I added a fat percentage column and a corresponding bulk extension factor. Enriched doughs need roughly 25% more bulk time per 10% fat by weight. There are real limitations to this approach. A bread making planner cannot predict how your specific kitchen will behave. If your apartment runs 5°F warmer in summer than the thermometer outside says, the planner will be off by an hour. If your Dutch oven retains heat differently than the one I used to calibrate my bake times, your crust color will vary. The planner is a starting point, not a prophecy. The people who treat it like a rigid script end up frustrated when their dough doesn't match the sheet. The ones who use it as a reference frame and adjust based on visual cues end up with consistent results.

My workaround for the prediction problem is simple. After every bake, I write the actual outcome in the row next to the estimated values. Over twenty bakes, the gap between estimate and reality shrinks dramatically. I now trust my planner numbers within a 30-minute margin for standard sourdough at 75°F. That's good enough for home baking. Professional bakers need tighter tolerances and they use computer-controlled proofing cabinets. This planner isn't built for that environment. If you want to start using this without building it from scratch, search for "sourdough spreadsheet template google sheets" and modify whichever one you find to include the starter age column and hydration modifier I described. Those two additions alone will improve your results more than any fancy layout. The rest is just filling in your own data over time. One more thing that isn't obvious: a planner works best when paired with a simple log of observations. I keep a separate notebook where I write one sentence per bake about how the dough felt, how the crust looked, and what I'd change. The spreadsheet handles the numbers. The notebook handles the things the numbers can't capture. Together they form something closer to actual expertise than either one does alone.
