Chleb prądnicki is a traditionally made brown bread produced within the administrative boundaries of the city of Krakow in Poland since the 15th century. It is a huge and unique bread - the loaves weigh 4.5 kilos, its crust is very thick and it has a long shelf life, staying fresh for at least seven days.

It has a typical flavor and smell of bread made with fermented rye, and just like some cheeses, it develops its unique organoleptic properties after a period of maturation, its full flavor is best appreciated the second day after it has been baked.

Even though it is five times more expensive than standardly-made bread, it is highly popular and during the annual Bread Festival, it is often bought four times more than any other day .
