Tokaji, particularly Tokaji Aszú, is a wine that has captured the imaginations of wine lovers, sommeliers, and connoisseurs around the world for centuries. Revered for its balance of sweetness, acidity, and complexity, Tokaji is one of the most distinctive and celebrated sweet wines globally. But what makes Tokaji so sweet?
The sweetness in Tokaji wine, specifically Tokaji Aszú, is the result of a combination of natural factors, traditional winemaking techniques, and the unique terroir of the Tokaj wine region. From the effect of botrytis cinerea (noble rot) on the grapes to the methods used in harvesting and aging, each element contributes to the distinct sweetness of Tokaji. This article will explore the various aspects that make Tokaji such a sweet and complex wine, and why it has earned the title “Wine of Kings, King of Wines.”
The Role of Botrytis Cinerea: Noble Rot
What Is Noble Rot?
The most significant factor that makes Tokaji wine sweet is botrytis cinerea, a fungus commonly known as noble rot. Unlike the destructive rot that spoils most grapes, noble rot is beneficial for producing certain types of sweet wines. This fungus grows on the grapes in conditions where there is morning fog, followed by warm, sunny afternoons—conditions often found in the Tokaj wine region during harvest time.
Noble rot works by partially dehydrating the grape, causing it to shrivel and concentrate its sugars, acids, and flavors. The fungus also breaks down some of the grape’s skin, allowing the juice to become more concentrated and flavorful. The result is a wine with higher sugar levels, a more intense flavor profile, and a unique complexity that is characteristic of sweet wines like Tokaji Aszú.
How Noble Rot Affects Tokaji
In Tokaji winemaking, the process of botrytis affecting the grapes is key to creating the sweetness of the wine. As the fungus dehydrates the grapes, it also enhances the complexity of the wine by contributing rich flavors such as honey, apricot, dried fruit, and spice. The effect of botrytis on Tokaji grapes is so significant that it is often referred to as “liquid gold” in the world of wine.
Tokaji Aszú wines, in particular, are made from aszú berries—grapes that have been severely affected by noble rot. The more the fungus affects the grape, the more concentrated the sugars and the sweeter the wine. Aszú berries are typically harvested by hand, as the affected grapes must be carefully selected from the bunch. This meticulous selection process ensures that only the best botrytized grapes make their way into the final product.
The Impact of Climate on Botrytis
The Tokaj wine region, which lies in northeastern Hungary and parts of Slovakia, is ideally suited for the growth of noble rot. The region’s unique climate, which combines cool mornings with warm afternoons, creates the perfect environment for botrytis cinerea to thrive. The proximity of the Bodrog and Tisza rivers also contributes to the humidity levels necessary for the development of noble rot, making it a key player in the sweetness of Tokaji wines.
Noble rot typically develops in the late summer or early autumn, just before the harvest. As the weather conditions become more favorable, the aszú berries become more concentrated in both sugar and flavor. These perfectly botrytized grapes are harvested at the peak of ripeness and used to create the sweet, honeyed wines for which Tokaji is famous.
The Fermentation Process
The Effect of Fermentation on Sweetness
Once the botrytized grapes are harvested, they are used to create the base wine for Tokaji Aszú. The fermentation process in Tokaji winemaking is essential for the final sweetness of the wine. Tokaji Aszú is typically made by adding the botrytized grapes (the aszú berries) to a base wine, which is made from healthy, uninfected Furmint grapes. The fermentation of Tokaji Aszú is slower and more complex due to the high sugar content in the botrytized grapes.
Fermentation is a delicate process. The yeasts consume the sugars in the grapes, converting them into alcohol. However, the sweetness of Tokaji is preserved by stopping the fermentation process before all the sugars are converted into alcohol. This is achieved by controlling the fermentation temperature and time. In Tokaji, the wine is often fermented in barrels, which also contributes to the wine’s complexity, adding flavors like spice and a subtle oak influence.
Sugar Content and Sweetness Levels
The sweetness of Tokaji Aszú is often measured by its sugar content, with wines classified by puttonyos, a Hungarian term that refers to the number of aszú baskets (puttonyos) added to the base wine. The more aszú berries used, the sweeter the wine. The puttonyos scale traditionally ranges from 3 puttonyos (the lightest sweetness) to 6 puttonyos (the sweetest).
A Tokaji wine with 3 puttonyos has a lighter sweetness, while a Tokaji with 6 puttonyos is intensely sweet, with a high sugar concentration. The modern classification system now uses the wine’s residual sugar content in grams per liter to determine its sweetness, but the traditional puttonyos system remains popular, especially among collectors and wine enthusiasts.
The higher the puttonyos level, the more intense and concentrated the sweetness, and this is a key characteristic of Tokaji Aszú. The balance between sweetness and acidity is crucial in creating a wine that is not cloying but rather refreshing and complex.
The Influence of Grape Varieties on Sweetness
Furmint and Hárslevelű
The primary grape used in Tokaji Aszú is Furmint, a native Hungarian grape variety known for its high acidity and ability to produce wines with excellent aging potential. Furmint grapes are typically the first to develop botrytis in the Tokaji region, making them ideal for the production of sweet wines. Their high acidity helps to balance the sweetness, preventing the wine from becoming too heavy or syrupy.
Another important grape used in Tokaji is Hárslevelű, which contributes to the wine’s aromatic profile. While Furmint provides the structure and acidity, Hárslevelű adds floral and citrus notes, creating a more rounded and balanced flavor. The combination of these two varieties, along with the influence of noble rot, is what makes Tokaji wines so distinctive.
Other Grape Varieties and Their Roles
While Furmint and Hárslevelű are the dominant grape varieties used in Tokaji, other varieties such as Kabar and Sárgamuskotály are also used in some Tokaji blends. These grapes can add unique flavors and aromas, though they are typically less common in the production of Tokaji Aszú.
The diversity of grapes used in Tokaji allows winemakers to create wines with different flavor profiles, ranging from more citrusy and floral to richer, more honeyed styles. This variety in flavor, combined with the influence of noble rot, ensures that Tokaji wines are among the most complex and delicious sweet wines in the world.
The Influence of Oak Aging on Sweetness
Oak Barrels and Flavor Development
The aging process is another factor that affects the final sweetness and complexity of Tokaji. Tokaji Aszú wines are often aged in oak barrels, which not only help to soften the wine but also contribute additional flavors and textures. Oak aging imparts subtle notes of spice, vanilla, and toasted wood, which complement the natural sweetness of the wine.
The length of time that Tokaji spends in oak barrels also plays a significant role in the development of its sweetness. Longer aging can lead to greater complexity and depth of flavor, with the wine developing more nuanced characteristics such as caramel, dried fruit, and honey. Oak aging also helps to integrate the sweetness and acidity of the wine, making it more balanced and harmonious.
The Role of Aging in Tokaji’s Longevity
Tokaji Aszú is known for its incredible aging potential. The wine can remain sweet and vibrant for decades, thanks to its high acidity and the preservation of its sugar content. As Tokaji ages, its sweetness evolves, becoming more refined and complex. Older Tokaji Aszú wines may develop flavors of dried fruit, candied peel, and even a hint of nuttiness, adding layers of depth to the sweetness.
The ability to age Tokaji for such long periods without losing its sweetness is one of the factors that has contributed to its legendary status. Wines that were made hundreds of years ago can still be enjoyed today, showcasing the remarkable longevity of Tokaji Aszú.
