Barrel aging - How does the oak actually get into the wine?

For people who don't know much about wine, the language of wine connoisseurs must sometimes sound strange. Recently, a winemaker friend of mine said: "Oh, you can really taste the American oak!" Of course, he meant that the wine was "aged in oak barrels". As an expert, he can also taste what kind of oak it must be. Even if hardly anyone has such a trained palate, the topic of "aging in wood" is very present in the wine scene. Reason enough to take a closer look at it. /// 2 min. reading time


Into the Wood

 

After fermentation, some wines are placed in wooden barrels instead of stainless steel tanks. Wooden barrels come in various sizes. The smaller the wooden barrel, the larger the contact surface between the wooden barrel and the wine. A barrique barrel, for example, has a capacity of 225 liters, while a large wooden barrel holds more than three times that amount. (Side fact: The world's largest wine barrel is located in Bad Dürkheim. It holds an impressive 1.7 million liters and houses a restaurant as well as a cozy wine tavern.)

 

 

Micro-oxidation

 

The wooden barrel differs from the stainless steel tank, among other things, in that it is not completely airtight. This fact leads to micro-oxidation (oxygen contact). The wine matures faster and more harmoniously in wooden barrels. For the taste, this means more spice and somewhat less fruit/acidity. Tannins (also called tannins) become softer, rounder, silkier and creamier through micro-oxidation.

Toasting

 

Not only the wood itself imparts a flavor. The so-called toasting of the barrel has a strong influence. For this, the inside of the wooden barrel is heat-treated and flamed. This later leads to more or less intense roasted aromas in the wine.

Usage

 

Barrique barrels can be used multiple times: In the first year, the wood imparts the most flavor. This diminishes year after year until, after about the fourth year, its flavor is so leached out that it is primarily used as a neutral storage vessel. Often, a portion of the wine is placed in neutral wooden barrels and another portion in new wooden barrels. Later, both portions are combined to achieve a harmonious influence of wood in the wine.
