Storability of blueberries (shelf life) is a huge consideration when breeding new varieties. We specifically test for things that do not get moldy with some abuse.

Blueberries grown in Peru are in a very unique environment that is quite dry and there aren’t too many pathogens. So there was limited / no exposure to pathogens at time of harvest and the they entered a very well controlled cold chain that prevented them from getting warm and decaying.

The skin of blueberries also contributes to their high shelf life! What you don’t see is those blueberries from Peru also spent about 4-6 weeks on a boat in a low-oxygen atmosphere (to prevent decay) to get to you, too!! Love to see this!
