The variety has been grown for the past 150 years in the districts of Bangalore Urban, Chikkaballapur and Kolar.[2][3] It is cultivated exclusively in an area of about 5,000 hectares, mainly in the Nandi Valley;[4] and about 450,000 tonnes of the fruit are produced annually.[2]
Bangalore Blue is closely related to the American Concord variety which has a strong natural resistance against phylloxera bugs. The variety has a "foxy flavor" and a soft skin.[5]
The ideal conditions needed to grow Bangalore Blue are: soil of red sandy loam type, day temperature of 35 °C to 37 °C and night temperature of 12 °C to 15 °C. As these conditions are found around the Bangalore region, the variety is grown exclusively there.[2]
The grape is mainly used for raw consumption, making jams and jellies, juice and juice concentrates; and in fortified wines.[2][3]
The Department of Horticulture proposed the registration of Bangalore Blue under the Geographical Indications of Goods Act, 1999, to the Office of the Controller-General of Patents, Designs and Trademarks, Chennai, in order to make it exclusive to the farmers in the region and increase its brand value.[3][6] It was granted the Geographical indication status, three years later, in 2013.[2] This allowed the Bangalore Blue Grapes Growers' Association headquartered in Chikkaballapur to get patent rights to cultivation of the variety.[6]
