Which bread molds the fastest bakery or store bought bread?

Bakery bread.

Bakery bread is typically made with fresh, high-quality ingredients and contains more nutrients than store-bought bread. This means that it also has a higher moisture content, which makes it more susceptible to mold growth. Store-bought bread, on the other hand, is often made with processed ingredients that have a lower moisture content, making it less likely to mold. Additionally, store-bought bread is typically packaged in airtight containers, which further inhibits the growth of mold.
