Ruby Roman grapes are the most expensive grapes on the planet. Meticulously cared for, cultivated, and harvested, it’s incredible what these grapes sell for once they make it to the market. And if they do meet the standards to sell, they could cost you around $90 to $140 a bunch.
But, why are these grapes so expensive, and what makes them so great? Keep reading to see why the Ruby Roman grapes are the priciest in the world.
History of the Ruby Roman Grapes
In 1995 a group of grape farmers in Ishikawa, Japan, started on their journey to producing a large red grape variety. These farmers submitted a proposal to the Prefectural Agricultural Research Center, where they planted over 400 experimental vines. Out of these 400 vines, only four produced red grapes, and only 1 met the expectations of these grape breeders.
Over the following 14 years, the breeders, farmers, and researchers constantly worked on selective breeding, increasing the grape’s size, enhancing the taste, color, and ease of growing and cultivating.
After making its big debut in 2008, there was a media sensation around the Ruby Roman grapes after a 700-gram bunch sold for 10,000 yen which is $910 American. This crowned it as the most expensive grape throughout the globe. Then again, in 2016, a bunch of 26 grapes sold for 1.1 million yen or $11,000 American.
The 3 Classes of Ruby Roman Grapes
Ruby Roman is a name that describes a variety of grapes, but every bunch must meet the highest of expectations to meet the qualifications of having said name. Each grape within the bunch needs to weigh 20 grams each and have a sugar content of 18 percent. And these numbers must be exact.
These grapes go through the wringer before going anywhere near a supermarket or luxury fruit market in Japan. They have to meet the size requirement a color requirement and can also bear no blemishes or odd shapes.
Superior Ruby Roman grapes meet the above qualifications and are good to sell.
Special Superior means these grapes have surpassed the above stipulations. Meaning they will have the best color, shape, size, and sugar content over 18 percent.
To be in the Premium class of Ruby Romans, each grape needs to weigh 30 grams, and the bunch has to total over 700 grams in total. This means the bunch of grapes has to meet a level of perfection. And when these grapes meet these perfection requirements, for example, they can sell at auction for around $12,000.

When planting the grapes, you want to pick an area with well-drained soil and tons sunlight. Waterings depend on your climate. If there is heavy rainfall, the waterings can be light, but if there is little to no rain, make sure the topsoil stays moist and never completely dries out.
When fertilizing, choose a well-balanced fertilizer specifically made for grapes and apply this twice a year, once in the spring and fall.
Pruning is another important aspect when keeping a Ruby Roman grapevine happy and healthy. It is best to prune the vine in March or April, along with the first fertilization of the year.
