What is the flavor of candy conversation hearts?

Candy conversation hearts that are made by the candy manufacturer NECCO underwent a major flavor revision in the early 21st century, converting from more old-fashioned fruit and spice flavors to fruit flavors such as strawberry, lemon and blue raspberry. The original candies had flavors such as mint, banana and grape.

There was some backlash to NECCO's decision to update their Sweethearts candy brand with more modern, "all-natural" flavors and colors. Fans of the original candy felt the change in color and texture made the conversation hearts unpalatable. In 2010, a columnist for The Dallas Morning News called the updated flavors "either cloyingly sweet or unexpectedly tart."
