There are several; types of grapes:
Grapes are grown throughout the United States and Canada, and there are numerous varieties grown across different regions of the countries. These grape varieties differ in their characteristics, flavor profiles, and ideal growing conditions.

- Concord grapes are ready for harvest in late summer or early fall when the berries turn deep purple with a slight bloom. The fruit should be firm but not overly soft.

2. Thompson Seedless Grapes:
- Thompson Seedless grapes, also known as Sultana, are a popular green grape variety in the U.S., favored for eating fresh, making raisins, or using in salads.
- They are primarily grown in California, where the Mediterranean climate provides ideal conditions for grape cultivation.
- Thompson Seedless grapes reach their peak ripeness in late summer. Look for a pale green color, slightly translucent berries, and a sweet fragrance.

- When harvesting wine grapes, it is essential to consider the winemaker's desired characteristics. Grapes can be hand-picked or machine-harvested, depending on the vineyard's practices.
It's important to note that grape harvesting times can vary depending on the specific region and local climate conditions. Additionally,
different grape varieties may have slightly different harvesting techniques. Always consult local resources, vineyard experts, or agricultural
extension services in your area for precise information on grape varieties, growing regions, and harvest timing.
Properly harvested grapes can be enjoyed fresh or used in various culinary applications such as winemaking, cooking, or preserving.

Wikipedia and the USDA provide the following nutritional analysis of grapes
As raw fruit, sweet grapes provide little nutrient content per
100 g serving (nutrient table). Dietary fiber and vitamin C are
present in moderate content while other vitamins and dietary
minerals each supply less than 10% of the Daily Value (DV) per
serving, respectively (table).
Compared to sweet grapes, raw sour grapes contain slightly higher content per 100 g of vitamin C (12% DV) and vitamin A (8% DV) (table).
