Compare observations before and after the oven
| Stage or observation | Clues it may have been early | Clues it may have gone too far |
|---|---|---|
| At the end of bulk | Little expansion for that recipe, limited aeration, tight feel. | Expanded earlier and now feels weak or hard to handle. |
| Shaped at room temperature | Loaf still feels tight and shows little expansion for its formula. | Loaf has lost strength or is difficult to move without deflating. |
| After baking and cooling | Dense areas with a few large irregular tunnels. Sometimes a tight base or a burst where the dough found a weak point. | Low profile and weak oven spring, especially if the loaf visibly lost shape before baking. The crumb may look compressed. |
The table gives clues for a wheat sourdough that you can compare with its own recipe. Flour blend, hydration, shaping, and oven conditions also affect the result. A loaf shaped with loose tension can spread even when its fermentation is on track. If you use a poke test, treat it as an observation during a suitable final proof. The response of cold dough can be misleading. [3] [4] [5]
Separate bulk from final proof
When you compare two loaves, write down the moment you shaped each one. Before that point, record the dough temperature, rise from the same baseline, and whether the dough felt tight, aerated or weak. After shaping, record the proof location, time and condition. For a fridge proof, include the fridge reading if you have one and any time on the counter before chilling. [6] [2]
Suppose a loaf started final proof tight after limited expansion in bulk. A short final proof would add to the evidence of an early bake, but that record still cannot tell you which stage mattered most. Repeat the formula with the same final-proof conditions and first adjust the bulk decision. If the dough was well developed at shaping and became fragile only after a much longer proof than usual, compare a shorter final proof with bulk kept as similar as possible.
A published comparison and how to use it
Tom Cucuzza’s *A Tale of Four Loaves* compares multiple sourdough loaves with different fermentation histories. Use his photos and observations to see how changes in the dough and in the baked slice can line up. Compare your own loaf with the observation sequence as well as the appearance. A single matching tunnel or flat edge gives you a hypothesis to check. [7] [3]
To make your own comparison, use one familiar formula and keep the flour, loaf size, shaping method, oven setup and cooling time consistent. If you want to examine final proof, keep bulk as similar as you can and vary the final proof only. If you want to examine bulk, hold the final-proof plan steady and record when each dough looked ready to shape. Slice through the same part of each cooled loaf. Photograph both slices in the same light and label the timings beside them.
What to do with an ambiguous loaf
Imagine a flat loaf with a tight base, a few holes near the top and no record of how it handled before baking. The crumb is compatible with insufficient fermentation, but the profile could also reflect poor shaping tension, a sticky turn-out or an oven issue. For the next bake, take a photo at the end of bulk and another immediately after you release the loaf from the basket. If it held shape until scoring but failed to spring in the oven, check preheat and baking setup. If it had already collapsed on release, look back at dough strength, proof and how it released.
Crispy Crust’s planned bake log would pair those photos with separate bulk and final-proof entries. You could review a loaf in order and see where its behaviour first changed, then copy the formula for a single-variable repeat.
