While this popular fruit is available year-round, fall is the harvest season for some of the most popular types including Thompson seedless and the red globe. Most grapes are processed into wine or raisins, but fresh grapes are a great for snacking, livening up autumn salads, adding a tangy-sweet note to fresh salsa, and even cooking alongside meat and poultry. Check for grapes that look plump and have a "bloom" similar to what you'd find on blueberries.
