The world of wine is full of fascinating varietals, aging techniques, and nuanced characteristics that keep even the most experienced sommeliers and winemakers intrigued. One such varietal that often piques curiosity is Zinfandel, particularly when it’s labeled as “Old Vine Zinfandel.” Many wine enthusiasts and novices alike may find themselves asking the question: “Is old vine Zinfandel red or white?” This seemingly simple question invites a deeper exploration of the wine’s origins, its unique characteristics, and why the age of the vines plays such a critical role in defining its profile. Let’s unravel this query by diving into the world of Old Vine Zinfandel, examining the nuances that distinguish it and understanding its classification in the grand scheme of wine production.
What Is Zinfandel? An Introduction to the Grape
Before answering whether Old Vine Zinfandel is red or white, it’s essential to understand Zinfandel itself. Zinfandel is a grape variety that has become one of the most iconic in California, though its roots trace back to Europe. Originating in Croatia and later brought to the United States through Italy’s Primitivo varietal, Zinfandel has been cultivated in California for over 150 years. Today, it is widely recognized for producing bold, flavorful wines that embody the Californian terroir.
Zinfandel grapes are known for their deep, rich colors and strong flavor profiles, which can range from sweet and jammy to dry and peppery, depending on the winemaking process. The wine can be produced in various styles, from fresh, light wines to full-bodied, complex expressions. The grape itself thrives in warm climates, which is why California’s Central Valley, Napa Valley, and Sonoma County are prime locations for Zinfandel cultivation.
The question of whether Zinfandel is red or white arises when considering its most well-known production: red wine. But does this apply to Old Vine Zinfandel as well? To answer this, we need to explore what sets Old Vine Zinfandel apart from regular Zinfandel.
Defining “Old Vine” and Its Significance
The term “Old Vine” is often associated with a special quality of grapevines, but there is no universal definition of what qualifies as an “old vine.” In general, old vines are typically over 50 years of age, though in some cases, vines as young as 30 years may be considered “old” depending on the region and grape variety. The importance of old vines lies in the fact that they produce fewer but more concentrated grapes, leading to wines that are more complex and balanced.
How Old Vines Influence the Wine’s Characteristics
Old vines are often able to develop deeper root systems that allow the vines to better withstand droughts and adverse weather conditions. This ability to tap into the earth’s minerals and nutrients gives old vines an advantage when it comes to producing fruit that reflects the unique qualities of the terroir. For Zinfandel, this means the fruit tends to be more intense in flavor, with pronounced fruitiness, spice, and tannin structure.
Another key characteristic of old vines is their reduced yields. While young vines may produce large quantities of fruit, old vines typically produce fewer, but more concentrated, berries. This leads to a wine that is often richer, with more complexity and layers of flavor. This is why many winemakers consider old vines to be invaluable when crafting premium wines, especially for varietals like Zinfandel.
But does this mean that Old Vine Zinfandel is only red wine?
Old Vine Zinfandel: Red or White?
Zinfandel is predominantly known for producing red wines, and when we refer to Old Vine Zinfandel, we are almost certainly talking about red wine. The Zinfandel grape, when harvested, has a deep purple-blue color, and its juice is fermented with the skins to create the characteristic red hues found in the final wine. The fermentation process, where the skins are left in contact with the juice, is what gives red Zinfandel its color and much of its flavor complexity.
However, Zinfandel can also be made into white wine through a process called “blanc de noir,” where the grape skins are removed quickly after pressing, allowing only the clear juice to ferment. This results in a much lighter wine, often called White Zinfandel. White Zinfandel is a style of rosé wine that became particularly popular in the 1980s, known for its slightly sweet and refreshing characteristics.
White Zinfandel vs. Old Vine Zinfandel
It’s important to distinguish between White Zinfandel and Old Vine Zinfandel. The former is a type of rosé wine made from Zinfandel grapes, while the latter refers to red wine produced from Zinfandel grapes grown on old vines. The production of White Zinfandel involves using the Zinfandel grape but processing it differently to achieve a pale, pinkish hue.
Old Vine Zinfandel, on the other hand, refers to the red wine made from older Zinfandel vines. These wines are typically more robust, concentrated, and often higher in alcohol content. The term “Old Vine” has become somewhat of a marketing tool, but it also signifies the unique quality and depth of flavor that comes from these older vines. When referring to Old Vine Zinfandel, we are almost always talking about red wine.
The Vinification Process of Old Vine Zinfandel
Old Vine Zinfandel is crafted through a traditional winemaking process that emphasizes the grape’s natural qualities. Here’s a detailed look at the vinification of this unique wine:
Harvesting and Sorting
The process begins with careful harvesting. Old vines generally produce smaller yields, but the quality of the fruit is exceptional. Winemakers typically hand-pick the Zinfandel grapes to ensure that only the best fruit makes it into the fermentation process. Once harvested, the grapes are sorted to remove any under-ripe or damaged fruit.
Fermentation
After sorting, the grapes are destemmed and crushed. The juice is then placed in fermentation tanks, where the fermentation process begins. In the case of Old Vine Zinfandel, the fermentation often takes place in open-top fermenters, which allows the winemaker to punch down the cap of skins that forms during fermentation. This process helps to extract more color, tannins, and flavor from the skins, contributing to the rich, full-bodied character of the wine.
Aging
Once fermentation is complete, Old Vine Zinfandel is typically aged in oak barrels, often French or American oak. The aging process imparts additional complexity, with flavors such as vanilla, spice, and subtle toastiness blending with the fruit-forward characteristics of the wine. The length of time spent in oak varies, but many winemakers choose to age Old Vine Zinfandel for anywhere between 12 and 18 months to achieve a balanced, harmonious wine.
Bottling
After aging, the wine is clarified and then bottled, where it may continue to evolve and mature for months or even years. Due to the concentration of flavor from the old vines and the oak aging process, Old Vine Zinfandel is often a wine that improves with age, revealing deeper layers and more refined tannins as it matures in the bottle.
The Flavor Profile of Old Vine Zinfandel
One of the defining features of Old Vine Zinfandel is its rich and complex flavor profile. The wine tends to have an intense fruit character, often showcasing flavors of ripe blackberry, black cherry, raspberry, and plum. This fruitiness is complemented by savory elements like black pepper, clove, and sometimes even a hint of smokiness, depending on the oak aging.
As Old Vine Zinfandel is usually a red wine, it also features a robust tannin structure, which contributes to its full-bodied mouthfeel. The acidity in the wine is typically balanced, providing a fresh, lively finish that prevents the wine from feeling too heavy or overly jammy. The long aging process imparts depth and richness, making Old Vine Zinfandel a wine that can be enjoyed both young and after some years of bottle aging.
What Makes Old Vine Zinfandel Unique?
The key factor that makes Old Vine Zinfandel so unique is the age of the vines. Older vines produce smaller, more concentrated grapes, which in turn results in wines with greater complexity and depth. Additionally, the lower yields from old vines mean that the vines are focusing their energy on fewer, higher-quality grapes, making every bottle of Old Vine Zinfandel a testament to the vine’s age and the winemaker’s skill.
Moreover, Old Vine Zinfandel reflects the terroir in a way that younger vines may not. The deep root systems of older vines allow them to access nutrients and water sources that younger vines cannot, contributing to the unique expression of the vineyard’s soil, climate, and weather conditions. This connection to the land is a significant part of the wine’s identity.
Conclusion
To answer the question definitively: Old Vine Zinfandel is almost always a red wine. The grapes used to produce Old Vine Zinfandel are the same as those used for traditional red Zinfandel, and the winemaking process emphasizes extracting rich flavors and colors from the grape skins. While Zinfandel can be made into a white wine, known as White Zinfandel, this is a different style entirely.
Old Vine Zinfandel, with its concentrated flavors, full-bodied structure, and complex aroma profile, stands as a testament to the advantages of growing Zinfandel on old vines. It is a wine that reflects the history of the vineyard and the craftsmanship of the winemaker, providing a truly unique tasting experience that is both rich in flavor and deeply rooted in tradition.
Whether you are a seasoned wine enthusiast or a newcomer to the world of Zinfandel, Old Vine Zinfandel is a wine worth exploring. It offers a glimpse into the past, showcasing the fruits of decades of vine growth, and offers a rich, complex, and thoroughly enjoyable experience that can be savored with each glass.
