Ruby Roman is a traditional table grape variety originating from Iskihawa prefecture. This variety of grapes dates back to 2008. The grapes are red in color and their size is close to that of a ping pong ball – each grape weighs more than 20 grams.
Ruby Roman is very juicy and has low acidity and high sugar content. Each grape is tested and comes with a seal of certification. These rare grapes are very expensive – in 2019, a bunch of Ruby Roman grapes were sold for 1.2 million yen.
