Yes, there are terpenes that are more pronounced in wines made from old vineyards. These terpenes contribute to the unique and complex aromas and flavors found in these wines. Let’s delve into the reasons behind this phenomenon and explore some of the key terpenes that are commonly found in wines made from old vineyards.
Why are terpenes more pronounced in wines from old vineyards?
Old vineyards, typically defined as vineyards that are 30 years or older, often produce wines with distinct characteristics that set them apart from wines made from younger vines. There are several reasons why terpenes are more pronounced in wines from old vineyards:
- Root system: Older vines tend to have deeper and more extensive root systems, allowing them to access a wider range of nutrients and minerals from the soil. This can influence the synthesis of terpenes in the grapes.
- Lower yields: Old vineyards tend to produce lower yields of grapes, but with more concentrated flavors. This concentration of flavors can also result in higher levels of terpenes in the grapes.
- Vine maturity: As vines age, they develop more complexity and depth in their flavors. This maturity can also manifest in the terpene profile of the grapes.
Key terpenes in wines from old vineyards
Terpenes are a diverse group of organic compounds that contribute to the aromas and flavors of wines. While there are many terpenes found in wine, some are more commonly associated with wines made from old vineyards. Here are a few key terpenes that are often more pronounced in these wines:
- Linalool: This terpene is known for its floral and citrusy aromas, often found in white wines made from old vineyards. It can impart notes of lavender, bergamot, and lemon.
- Geraniol: Geraniol is another terpene with floral characteristics, often described as having rose-like aromas. It is commonly found in aromatic white wines from old vineyards.
- Myrcene: Myrcene is a terpene that can contribute to earthy and herbal notes in wines. It is found in both white and red wines made from old vineyards.
- Terpinolene: Terpinolene is a terpene known for its woody and herbaceous aromas. It can add complexity to wines from old vineyards, particularly red wines.
- Limonene: Limonene is a terpene with bright citrus aromas, often found in wines made from old vineyards. It can bring notes of lemon, orange, and grapefruit to the wine.
Effects of terpenes on wine quality
Terpenes play a crucial role in shaping the overall aroma and flavor profile of wines. When present in appropriate concentrations, terpenes can enhance the complexity and character of a wine. However, excessive amounts of certain terpenes can lead to overpowering aromas or off-flavors in the wine. Here are some ways terpenes can affect wine quality:
- Aroma intensity: Terpenes contribute to the aromatic profile of wines, providing a range of floral, citrus, herbal, and fruity notes.
- Flavor complexity: Terpenes can add layers of complexity to the flavor profile of wines, making them more interesting and dynamic on the palate.
- Ageability: Certain terpenes can help wines evolve and develop more nuanced flavors over time, contributing to their ageability.
- Balance: It is essential for wines to have a harmonious balance of terpenes and other compounds to ensure a pleasant drinking experience.
