The wineberry is the small, glossy, translucent-red aggregate fruit of an East Asian bramble, Rubus phoenicolasius, a raspberry relative that has become one of the most familiar wild-foraged berries of eastern North America. Bright, jewel-like and pleasingly tart-sweet, each berry is a hollow cup of many tiny juicy drupelets that slips cleanly off its core like a raspberry, and it is prized by foragers for its clean, sweet-sour, faintly wine-like flavour and for the ornamental red-bristled canes and calyces that make the plant unmistakable.
