Around this time of year, cranberries are a traditional and cherished addition to the holiday table—and UMass researchers are working to ensure that these beloved burgundy gems will thrive for generations to come.

Like many other crops, cranberries are at risk from the effects of climate change. The first week of September 2023 saw overnight lows in the 70s in the cranberry bogs of southeastern Massachusetts, including at UMass Amherst Cranberry Station in East Wareham, part of the UMass Amherst campus. Those temperatures are in contrast with the 50s or lower that cranberry growers and the researchers at Cranberry Station hope to see at that time of year. The red pigments that give cranberries their signature color—anthocyanins—are produced in the fruit as a response to environmental cues, like day length and temperature. Without cooler temperatures, cranberries remain white or pink and growers are “chasing color”—waiting for the berries to turn deep red for collection and processing, and hoping to beat the rot that can happen if it takes too long.

Take a peek inside Cranberry Station to see how researchers are working to support the next generation of growers and the $1.7B Massachusetts cranberry industry.
