At first glance, dewberries look incredibly similar to their cousin, the blackberry. The main visual distinction between the two is the color. Dewberries have a purple-red hue while blackberries are a deep black color. These are larger than the blackberry when it comes to size. In taste, the blackberry has the edge as it is sweeter while the dewberry is a lot more acidic. Dewberries were widely cultivated at the start of the 20th century but started going out of fashion when year-round availability of other fruits started with the advent of modern canning and transportation.
