What temperature is suitable for serving a medium to full-bodied red wine such as Shiraz?

Serving medium to full-bodied red wines, such as Shiraz, at room temperature (15°C to 18°C) is considered ideal because it allows the wine to express its full range of aromas and flavors. At this temperature, the complexities of the wine, including its fruitiness, spiciness, and underlying tannins, can be appreciated without the wine feeling overly warm or muted.

Wines served too cold, as suggested in the other options, can suppress the aromatic qualities and flavors, making them less expressive. This is particularly important for richer, bolder wines like Shiraz, which benefit from being enjoyed at a warmer temperature. Therefore, maintaining the right serving temperature ensures an optimal tasting experience.
