Alcohol evaporates when the bread cooks

Seems like the consensus is that some remains.

A lot of online sources cite a 1926 study that said bread can have ‘up to 1.9%’ alcohol content. This more recent study from 1998 suggests that 0.4-0.6% ethanol by mass is more typical: https://auventdunord.ca/wp-content/uploads/2018/05/food-alco...

Some of it, but not all of it or even the majority[1]. For reference some breads bake in as little as 20 minutes so a fair bit of alcohol remains.
