Bubbles prefer cooler temperatures
Light, fruity sparkling wines, such as the majority of those produced using the tank (Charmat) method, are at their best when well-chilled, between 6 and 8 degrees Celsius. Sweet sparkling wines require slightly lower temperatures, between 5 and 7 degrees, as warmth would overly accentuate the taste of sugar. Non-vintage sparkling wines produced via the traditional method (secondary fermentation in the bottle) are best served between 7 and 9 degrees. This temperature preserves the balance between acidity and delicate notes of berries or yeast. Complex sparkling wines, primarily Champagnes and most vintage ones, best reveal their aromas of toasted bread and nuts at temperatures between 9 and 12 degrees.
Preserve freshness, highlight complexity
Lighter white wines, such as young Sauvignon Blanc, Pinot Grigio, and even recent vintages of Graševina from cooler climates or Malvazija, are best served at temperatures between 7 and 10°C to preserve their refreshing acidity. For more aromatic whites like Riesling or Traminer, a slightly higher temperature range of 8 to 11°C will highlight floral notes without compromising other characteristics. Full-bodied white wines and those aged in wood, most commonly Chardonnay, should be lightly chilled to between 10 and 13°C to allow their texture and complex aromas and flavors to shine.
Room temperature? Not even for reds
Light-bodied red wines, Pinot Noir being a typical example, retain their lively fruit aromas at 12 to 15 degrees Celsius, a temperature that also softens any excessive acidity. Medium-bodied wines, such as those made from Merlot, Frankovka, or certain Teran or Crljenak grapes, achieve a balance between fruit and spice notes and smooth out their tannins when served at 14 to 17 degrees. Full-bodied reds, like Cabernet Sauvignon, Syrah/Shiraz, Malbec, or Plavac Mali, are best served between 16 and 18 degrees so that the alcohol does not overpower the other flavors. Those were the room temperatures found in castles 100 or 200 years ago. Today, our rooms are often well above 20 degrees, far too warm for any wine, so the term room temperature should be avoided.
Sweet wines should also be chilled
Most dessert wines are served chilled to between 7 and 12 degrees Celsius, though the ideal temperature depends on the style. Sweet white wines and those from special harvests, such as Sauternes, Tokaji, Moscato and predikat wines (late harvest, selected harvest, and berry/dried berry selection), should be chilled to 7–10 degrees. This prevents an impression of cloying sweetness, where high sugar levels might otherwise feel heavy, while preserving the freshness of fine acidity. Fortified red wines, such as Port and most Sherries, handle temperatures between 13 and 18 degrees well. At this range, complex flavors develop beautifully without the higher alcohol content becoming overpowering.
