Sommelier Level 2 Practice Exam

What ave temp must be achieved to successfully ripen red grapes?

60°F 70°F 65°F 75°F

Correct Answer:

70°F

Explanation:

Grape ripening hinges on heat to drive sugar buildup and color development in red varieties. An average around 70°F provides the right balance: warm enough to push ripening forward, while not so hot that acidity drops too quickly or flavors become unbalanced. Cooler averages, like 60°F, slow ripening and can leave acidity higher and color less developed. Slightly cooler, such as 65°F, can still ripen but more slowly and with less emphasis on color, while hotter averages, around 75°F, can hasten sugar accumulation but risk sacrificing acidity and structure. So, 70°F is the optimal target for successful ripening of red grapes.
