What Are the Most Common Varieties of Chilean Grapes?

  • Flame

Cherry red color, seedless, sweet-tart, and crunchy. Medium-large grapes. Time to ripens/harvest around late May with a pH around 5.5 - 6.5 and years to bear along 2-4 years.

  • Thompson

Light green seedless, firm, round berries, sweet, juicy with very tender skin. One of the most popular table grapes. It is also the grape most used for raisins. The color of the grapes is yellow-green. Medium-large grapes. Time to ripens/harvest around August with a pH around 5.5 - 6.5 and years to bear along 2-4 years.

  • Crimson Seedless

The color of grapes is light red, very distinctive, sweet, juicy flavor, and elongated, pale pink berries. They have a crisp, firm skin with juicy pulp. The flesh is greenish-white and has a medium level of crispness. Time to ripens/harvest around July with a pH around 5.5 - 6.5 and years to bear along 2-4 years.

  • Red Globe

Red Globe is a variety of very large spherical, seeded crunchy, and juicy red grapes with firm flesh used mainly as a table grape. With an average bunch weight of approximately around 1000 G. The color of the grapes is red. Time to ripens/harvest around July with a pH around 6 - 6.5. Very good suitability for cold storage.

  • Superior

Frosty Green seedless, white round berries. Fairly small to medium long, compact, tapered bunches, and Tart-sweet flavor. Firm flesh and tender skin. With an average bunch weight of approximately around 250 to 500 G. Time to ripens/harvest around May with a pH around 5.5 - 6.

Quality Control/Certification

What is the best climate and soil to grow grapes?

  • Temperature

Table grapes typically require a hot and dry climate, i.e. warm days, cool nights, and low humidity. These generally produce higher-quality grapes. The season at a particular site must be long enough to allow both the fruit and the vegetative parts of the vine to mature. It must provide enough heat energy to ripen the fruit and vegetation. There must be adequate sunlight hours to ensure that a sufficient supply of carbohydrates is produced by photosynthesis to mature the fruit and vine and to maintain the future productive potential for healthier vines and sweetness of the fruit. There must be very little rain during the ripening period—this will prevent various grape diseases. Winter must be long enough to ensure a period of dormancy for the vines, and there should be no late frost because it will be a threat to the young buds. They are sensitive to freezing temperatures, which normally occur in winter and can damage and destroy flower clusters.

  • Soil requirements

Table grapevines must be vigorous to ensure high yields and quality; the better the soil, the healthier the vines, and the greater the chance for high tonnage and quality. Table grapes can be grown in a wide variety of soil types. The most important characteristics are good internal drainage and adequate depth. Waterlogged soils will lead to a reduction in vine health and added difficulties in vineyard management. Grapevines require deep, well-drained soil with a minimum of 75 CM to 1 M of permeable soil with no impeding layers (shallow bedrock, chemical, or physical hardpans) for optimum vine growth. Although grapevines can be grown in different soil types, they grow well in sandy loam soil with average fertility. Regardless of soil type, the drainage must be good because this will help the roots to spread and grow well. Avoid growing grapes in soils that contain clay because it may cause poor drainage and salt accumulation. Grapes are fairly tolerant to a wide range of soils and pH but do well in a pH of 5,5 to 6,0.
