These Are The Types Of Bread That Last The Longest In Your Fridge And Pantry - Tasting Table
Briefly

Bread can spoil quickly if not stored correctly. Prepackaged sandwich loaves tend to last longer due to preservatives, while sourdough, whole-grain, and enriched breads like challah remain fresher. Contrary to common belief, the fridge is not ideal for bread storage. Instead, it's best to keep bread on the counter in plastic bags for soft loaves or in a bread box or paper bag for rustic varieties. Enriched breads contain higher fat and sugar content, which helps them stay fresh longer. Stale bread can still be used creatively in various dishes.
To avoid the issue, it's worth it to do some research into the type of bread you're buying and how you're keeping it.
For those, a bread box, paper bag, or a dish towel are better storage options.
The reason enriched breads keep longer is because of their ingredients... their higher fat and sugar content helps them stay moist and soft for longer.
If all else fails, you can still use stale bread in a variety of ways, like croutons, breadcrumbs, or recipes like stuffing.
