Ruby Roman grapes are an extremely rare kind of fruit. Only 2,400 bunches of these grapes are produced each year and the reason for such low yield is simple cultivation.
Ruby Roman grapes are so magnificent that the cost of just one grape is about Rs 35,000 in India (€396). Each grape is thoroughly tested to guarantee its quality. A certification seal is kept on the grapes that are selected. There are strict rules for selling this grape.
