What Are the Primary Aromas in Wine?

Primary aromas in wine are aromas that come directly from the grape variety itself and are the scents that develop during the growing of the grapes and the fermentation process. These primary wine aromas in most wines are the most immediate expression and smell associated with the grape’s varietal character.

Fruit Aromas

Red and white wines will express different fruity notes depending on the grape variety and the winemaking process that is used.

  • Red wines: Red fruits of Cherries, blackberries, raspberries, strawberries, plums, currants
  • White wines: Apple, pear, citrus fruits (lemon, lime, grapefruit), stone fruits (peach, apricot), tropical fruits (pineapple, mango, passion fruit).

Floral Aromas

  • Roses, violets, orange blossom, honeysuckle, jasmine, lavender
  • More common in white wines like Gewürztraminer, Riesling, and Viognier

Herbal & Vegetal Aromas

Spice Aromas

  • Black pepper, white pepper, anise, licorice
  • Typical in varieties like Syrah/Shiraz and Gewürztraminer

Mineral Aromas

  • Wet stone, slate, flint, chalk, saline
  • Often found in cooler climate wines from areas with distinctive vineyard soils

These primary aromas are most prominent in young wines and tend to diminish as a wine ages, giving way to secondary aromas (from winemaking) and tertiary aromas (from aging). The intensity and specificity of primary aromas are influenced by factors like climate, soil, farming practices, and ripeness at harvest.

Secondary Aromas

After the primary characteristics in a wine reveal themselves, secondary wine aromas (also called fermentation aromas) may begin to express themselves. These wine aromas develop during the alcoholic fermentation process and malolactic conversion. The secondary characteristic emerges as yeasts convert grape sugars into alcohol and other compounds.

Key characteristics of secondary aromas include:

  • Yeast-derived aromas: Bread, toast, biscuit, beer, cheese rind
  • Lactic notes: Butter, cream, yogurt (from malolactic fermentation)
  • Fermentation fruits: Banana, pear drop, apple
  • Other notes: Nuts, lees contact, mushroom

These aromas are distinct from primary aromas (which come directly from the grape variety) and tertiary aromas (which develop during aging). Secondary aromas contribute significant complexity to a wine’s aromatic profile and reflect the winemaking techniques employed during fermentation.

Tertiary Wine Aromas

Tertiary wine aromas in wine are the scents that develop over time as the wine ages, either in oak barrels or in the bottle. These are not from the grapes themselves, but rather from other factors such as chemical reactions and oxidation that occur during maturation. They add complexity and depth to the wine.

Here are the main types of tertiary aromas:

Oak-Aging Aromas (from time spent in barrels)

  • Vanilla
  • Cedar
  • Clove
  • Coconut
  • Smoke
  • Toast
  • Chocolate
  • Coffee
  • Caramel

These come from the breakdown of wood compounds like lignin and hemicellulose, especially in toasted oak barrels.

Bottle-Aging Aromas (from long-term aging in bottle)

  • Dried fruits (fig, prune, raisin, dried apricot)
  • Nutty notes (hazelnut, walnut, almond)
  • Earthy tones (mushroom, forest floor, wet leaves)
  • Leather
  • Tobacco
  • Petrol (notably in aged Riesling)
  • Soy sauce or balsamic (in very mature reds)
  • Savory or umami character

Conclusion

Understanding the key difference between these three categories: Primary, secondary, and tertiary wine aromas, will enhance the wine enjoyment experience. Primary aromas will reveal themselves first, while secondary and tertiary aromas will often reveal themselves when tasting wine after it has had time to breathe. The next time you open a bottle of wine, try to see how many primary, secondary, and tertiary wine aromas you can identify.
