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.
This light is given off by specific atoms or molecules at specific wavelengths, and no others. This is called an emission spectrum. Blue and green flames, it turns out, have an emission spectrum. But they don't contain copper, barium, cesium, or any of the other elements that burn to give off blue or green light.
