Most baking issues do not manifest when baking one or two loaves. But they present themselves immediately when you scale. Dough reacts differently. Any little inefficiency becomes evident in the final product.

Assuming that the dough will behave the same way

A scaled-up dough will not behave or act identically to a small batch. Larger doughs contain more heat. Therefore, they ferment differently. They can be tighter or looser than anticipated.

Do not depend solely on the timings of smaller bakes. You might risk under- or over-fermenting it. Rather, observe the dough itself:

• Volume increase
• Surface texture
• Extensibility.

These aspects are less sensitive to the timings. They are the best indicators when the batch size grows.

Miscalculating hydration at scale

Hydration rarely scales well. Large amounts of flour combinations absorb water differently. Therefore, small inaccuracies in measurement will be more pronounced.

Do not combine all the prepared water at once. This may result in a hard-to-fix dough. 

The solution is to withhold a small amount of water. Then, add it progressively during mixing if need be. This provides better control. It limits the possibility of over-loose dough.

Overloading mixing equipment

Mixers have their limits. Overworking them may result in uneven gluten structure. When you overload it, you risk overmixing the dough at the hook. And the dough at the edges will not develop well.

Consider the batch size in comparison to the equipment. Does the dough appear uneven? Divide it into two portions. Here, consistency is more important.

Ignoring ingredient variability 

Ingredient inconsistencies manifest when baking large quantities. Beware of variations in:

• The quality of flour
• Moisture level 
• Age.

These differences can influence each loaf in a batch.

If you bake on a large scale, have a reliable wholesale flour supplier. This will minimize variance. It also makes it easier to achieve repeatable results.

Underrating space and time

Larger batches occupy more physical space. This comes up during:

• Bulk fermenting
• Shaping
• Proofing.

Dough pieces that are crowded ferment unequally. They may also lose their structure.

Before scaling up, check that you have an adequate amount of:

• Bench space
• Proofing baskets
• Baking trays. 

Your timing should be right. Avoid wasting excess time between steps. This can cause the dough to lose strength or overproof.

Baking too much at once

When you load more than one loaf, the oven’s performance changes:

• It reduces heat recovery
• Causes uneven distribution of steam
• Airflow is constrained.

Do you experience pale crusts or uneven bakes? Reduce the load or bake in shifts. 

It can also be good to rotate loaves halfway through. But it is more convenient to plan batches that fit into your oven.

Skipping documentation

At greater volumes, it is dangerous to rely on memory. Minor changes are cumulative. Unless you take notes, you will not know what has led to a problem.

Document metrics like:

• Hydration
• Temperatures
• Fermentation durations
• Performance. 

This facilitates troubleshooting and re-running successful batches.

Concluding words

Baking at higher volume reveals the flaws of the process, equipment, and plan. Pay close attention to the dough, and improve sourcing and workflow. This will enable you to scale production without sacrificing quality and control.
