Bread training: Overall no. The salary expenses will go down (fewer night shifts) – a normal person doesn’t eat more than 200g of bread per day (so it costs less) – plus you have to bake fewer times – big loaves of bread can be baked in bigger quantities at the same time in the oven, it is more efficient in terms of the workforce input,  the electric bill will get lower, and the sourdough bread lasts longer. Baguette lasts less and baking baguette consumes more electricity. Also, you can make avocado toast, croutons, pain perdu, and croque monsieur with sourdough bread. Panettone training: Yes, but you will sell about 50 dollars product.
