What kind of Berry? mulberry, strawberry, raspberry, or Blackberries?
just kidding I know what you mean. The sharp taste of some varieties does resemble a raspberry flavor. In my collection Mavra Sika has that flavor, Hardy chicago is good, but has a sweet milder flavor. Negronne,
Some of the white varieties of figs have that flavor as well, Verdal Longue, Calvert, and Bataglia.
