The final stages of bread making - scoring, baking, and cooling - represent the culmination of all your earlier work, yet many bakers underestimate how profoundly these steps affect the final result. Understanding the science behind crust formation, oven spring, and flavor development during baking helps you troubleshoot issues that appear only in the finished loaf.

Crust color and texture depend on complex chemical reactions that require specific conditions to proceed properly. The Maillard reaction, responsible for the appealing golden-brown color and complex flavors, needs adequate surface sugars and sufficient heat. Pale crusts often indicate insufficient oven temperature, excessive steam throughout baking, or dough that was over-proofed and depleted of surface sugars.

Steam plays a contradictory but crucial role in crust development. During the first portion of baking, steam keeps the crust flexible, allowing maximum oven spring as the bread expands rapidly in the heat. However, steam must be removed or reduced during the latter part of baking to allow proper browning and crisping. Many home bakers create beautiful oven spring with good steam but end up with pale, soft crusts because they don't vent the steam adequately.

Oven spring - the dramatic final rise that occurs in the first minutes of baking - represents the climax of fermentation. As the dough rapidly heats, gases expand, yeast makes its final burst of activity before dying off, and moisture converts to steam, creating internal pressure. Poor oven spring usually traces back to fermentation issues: over-proofed dough lacks the structural integrity to expand further, while under-proofed dough may not have developed sufficient gas cells for dramatic expansion.

The placement of your bread in the oven affects both crust development and overall baking. Bottom heat creates a crispy bottom crust, while top heat promotes browning. If your bread routinely burns on the bottom, try using a baking stone to moderate the heat transfer, or place your pans on a higher rack. Conversely, pale tops might benefit from moving closer to the top heating element during the final phase of baking.

Internal temperature provides the most reliable indicator of doneness, but understanding what those temperatures mean helps troubleshoot texture issues. Bread continues cooking after removing from the oven as residual heat completes protein coagulation and starch gelatinization. Underbaked bread feels gummy and may collapse slightly as it cools. The internal structure hasn't fully set, leaving a dense, moist crumb that's unpleasant to eat.

Cooling is perhaps the most overlooked phase of bread making, yet it's critical for proper texture development. Starches continue to transform during cooling, and moisture redistributes throughout the crumb. Cutting bread too early releases steam that should be redistributing, resulting in a gummy texture even if the bread was properly baked. The hardest part of bread making might be waiting for that perfect slice.

Off-flavors in bread often develop during fermentation or baking, and identifying their source helps prevent recurrence. Overly sour bread usually indicates over-fermentation or contamination with wild yeasts or bacteria. Bitter flavors might come from oxidized fats in the flour or over-development during mixing. Metallic tastes often trace to reactive bowls or tools, while stale flavors suggest old flour or insufficient fermentation time.

The environment during baking affects more than just crust color. Dry oven air creates different crust characteristics than humid conditions. Some bakers prefer the crispy, shattering crusts that develop in dry heat, while others favor the chewy, substantial crusts that form with steam. Understanding these preferences helps you adjust your technique to achieve the specific crust character you enjoy.
