2. Taste & Consumption

• Flavor Profile:
  • Table Grapes: Sweet (Thompson) to tart (Concord).
  • Wine Grapes: Varies from floral (Riesling) to earthy (Pinot Noir).
• Consumption:
  • Fresh: Snacks, salads, cheese boards.
  • Processed: Wine, juice, jams, raisins.
  • Cooking: Roasted with meats, in tarts, or fermented into vinegar.

3. Nutrition & Health Benefits

• Nutritional Value (per 100g fresh):
  • Calories: 69 | Fiber: 0.9g | Vitamin C: 18% DV | Vitamin K: 28% DV
  • Glycemic Index (GI): 45–53 (low to moderate).
• Health Benefits:
  • Heart Health: Resveratrol lowers LDL cholesterol and improves circulation.
  • Antioxidants: Polyphenols combat oxidative stress and inflammation.
  • Digestion: Fiber and water content aid gut health.

4. By-Products & Processing

• Wine: Fermented grape juice; global market worth $364 billion (2023).
• Raisins: Sun-dried or mechanically dehydrated grapes.
• Grape Seed Oil: Cold-pressed for cooking and cosmetics.
• Pomace: Leftover skins/seeds used for animal feed, fertilizer, or biofuel.

5. Storage & Preservation

• Fresh Grapes:
  • Refrigerate unwashed in ventilated bags (1–2 weeks).
  • Rinse only before eating to prevent mold.
• Freezing: Wash, pat dry, and freeze on trays (6–8 months).
• Drying: Sun-dry or use dehydrators at 60°C for 24–48 hours.

6. Culinary Uses & Recipes

1. Roasted Grape & Goat Cheese Crostini:
   • Toss grapes with olive oil and rosemary; roast at 200°C for 15 mins. Serve on toasted baguette with goat cheese.
2. Grape Clafoutis:
   • Bake grapes in a custard batter (eggs, milk, sugar) at 180°C for 30 mins.

7. Major Producers, Exporters & Importers

• Top Producers (2023):
  1. China (14M tons; table grapes).
  2. Italy (8M tons; wine and table grapes).
  3. USA (6M tons; California leads wine production).
  4. Spain (5.5M tons; Tempranillo and Airén grapes).
• Leading Exporters: Chile, Italy, Spain, South Africa.
• Key Importers: USA, Germany, UK, China.

8. Cultivation & Climate Requirements

• Ideal Conditions:
  • Climate: Mediterranean (15–25°C); requires dry summers and mild winters.
  • Soil: Well-drained, loamy soil; pH 5.5–6.5.
  • Pollination: Self-pollinating; wind and insects aid fertilization.
• Home Planting:
  • Choose disease-resistant varieties (e.g., Mars Seedless).
  • Use trellises for support; prune annually for airflow and yield.

9. Return on Investment (ROI)

• Costs:
  • Vineyard Setup: $20,000–$50,000/acre (vines, trellises, irrigation).
  • Maintenance: Pruning, pest control ($2,000–$5,000/acre annually).
• Yield: 5–15 tons/hectare (table grapes); 3–5 tons/hectare (wine grapes).
• Profitability: Wine grapes earn $1,500–$3,000/ton; premium table grapes fetch $4–$8/kg.

10. Challenges & Innovations

• Pests/Diseases: Phylloxera, powdery mildew, and botrytis.
  • Solutions: Grafted rootstocks, organic fungicides.
• Sustainability: Drip irrigation, cover crops, and solar-powered processing.
