Ruby Roman is a variety of table grape grown and marketed entirely in Ishikawa Prefecture, Japan. It is red in color and about the size of a ping-pong ball. The first Ruby Roman grapes went on sale in August 2008 for 100,000 Japanese yen (US$910) per 700-gram bunch, or $26 per grape.[1] They are said to be the most expensive variety of grapes.[2] In July 2016, a single bunch of Ruby Roman grapes, containing 26 grapes at a weight of about 700 grams, sold for 1.1 million yen (around $8400) in the year's first auction at a wholesale market in Kanazawa.[3][4][5] | ||||||
