Valpolicella Ripasso is a form of Valpolicella Superiore made with partially dried grape skins that have been left over from fermentation of Amarone or recioto. Winemaking in the region has existed since at least the time of the ancient Greeks.
Barium chloride, or any other barium salt, should burn with a green flame. When a barium salt is burned, the thermal energy is transferred to the outer electrons of the barium ions. They gain enough energy to excite them to a higher energy level. They then drop back to their ground state, releasing energy.
What you probably mean is copper salts, which are used to color flames. There are two commonly used flammable copper salts and they produce different colors. Cupric chloride burns blue. Cupric sulphide burns green. There are other metal salts that burn other colors as well, for instance Potassium chloride burns purple.
