## Abstract A mass spectrometric‐based procedure for anthocyanin profiling was set up to distinguish authentic __Vitis vinifera__ from hybrid red grapevine cultivars. 3‐__O__‐Monoglucoside and the related acetyl‐, __p__‐coumaryl‐ and caffeoyl‐monoglucoside anthocyanins occurred only in __Vitis vini
