Mostly blueberry and raspberry notes then blackberry and strawberry. It does have a overall jam flavor and not overtly sweet. It is not a dry vape and perfectly blended. It is sweet and jammy and does not need sweetener (my thoughts). The 4 berries are blended well in this flavoring.@Koolkiz what does the Jammy Berry taste like to you? Blackberry? Or is it more like boisenberry or a raspberry kind of berry?
