The ideal temperature for a wine cooler depends on the type of wine being stored. Here are some general guidelines based on the search results:

• White Wine: The temperature range for white wine is generally between 45°F (7°C) and 50°F (11°C) . Some sources suggest a range of 46°F-48°F (8°C-9°C) for light to medium-bodied white wines like Riesling, Pinot Gris, and Sauvignon Blanc.

• Red Wine: The temperature range for red wine is generally between 50°F (11°C) and 65°F (18°C) . For short-term storage, a constant temperature of 50°F-59°F (10°C-15°C) is recommended to avoid premature aging or agitation. For longer-term storage, a temperature of 53°F-57°F (12°C-14°C) is recommended to prevent spoilage and allow the wine to age and mature gracefully.

• Sparkling Wine and Dessert Wine: These wines should be served nearly ice-cold, with an ideal temperature range of 40°F-45°F (4°C-7°C) .

Its important to note that each type of wine has its own ideal temperature range, and that temperature can affect the taste and aroma of the wine. Its also important to avoid drastic temperature swings, which can cause the wine to pop and push out the cork. A dual-zone wine refrigerator can be helpful for managing different wine cooler temperatures for multiple wines.
