When comparing consecutive vintages in a vertical tasting, there are several key differences in aroma, flavor, and structure that can be observed:
Aroma
-
Each vintage will have its own unique aromatic profile, influenced by factors such as weather conditions during the growing season, grape ripeness, and winemaking techniques.
-
Younger vintages may exhibit more pronounced fruit aromas, while older vintages might show more developed secondary and tertiary aromas like earthy notes, tobacco, or leather.
-
The intensity of the aromas can also vary between vintages, with some years producing more expressive and powerful scents compared to others.
Flavor
-
Flavor profiles can differ significantly between consecutive vintages, reflecting variations in grape quality, ripeness levels, and overall growing conditions.
-
You may find that younger vintages have brighter, more vibrant fruit flavors, while older vintages display more complexity and depth with nuances of spice, herbs, or mineral notes.
-
Tannin levels can also vary between vintages, affecting the wine’s texture and mouthfeel. Some years may have softer, more integrated tannins, while others might be more firm and gripping.
Structure
-
The structural components of a wine, such as acidity, tannins, and alcohol levels, can differ from one vintage to another, impacting the overall balance and aging potential of the wine.
-
Acidity levels play a crucial role in a wine’s structure, providing freshness and ensuring longevity. Some vintages may have higher acidity, making the wine more vibrant and age-worthy.
-
Tannins, derived from the grape skins and seeds, contribute to a wine’s structure and aging potential. Differences in tannin ripeness and extraction can result in varying levels of astringency and mouthfeel.
