   • Red Globe: Large, red grapes with a sweet flavor, often used in fruit salads.
   • Crimson Seedless: Reddish-purple grapes, seedless and sweet, popular for snacking.
   • Concord: Dark blue or purple grapes, known for their intense flavor, used in juices, jams, and jellies.

2. Wine Grapes:
   Grapes specifically cultivated for winemaking are called wine grapes. They vary significantly in flavor profiles and characteristics. Some notable wine grape varieties include:

   • Chardonnay: A white wine grape producing wines ranging from light and crisp to rich and creamy.
   • Cabernet Sauvignon: A red wine grape known for its deep color, full body, and rich flavors of dark fruits.
   • Merlot: Another popular red wine grape, softer and less tannic compared to Cabernet Sauvignon, with flavors of plum and berries.
   • Pinot Noir: A delicate red wine grape producing light to medium-bodied wines with notes of red fruits and earthiness.
