Understanding Hungarian Oak

10 minutes read

It’s no longer a secret that Hungary is a great wine producing country. But it is not as widely known that Hungary is also a big producer of high-quality oak barrels. Hungarian oak has been used for making wine barrels for centuries, but wineries have only been emphasizing it as an important feature of their wines for the past few years. They say that Hungarian oak barrels give a different taste profile than American or French ones, and Hungarian oak is used in California, South Africa, Italy, and even France.

Why Do Oak and Wine Go So Well Together?

The first barrels we have records of were made of palm tree wood in Mesopotamia. In the past barrels were made mostly for transportation and storage. You could not simply buy a bottle of wine; you had to buy it by the barrel. Barrels are still made of many other woods, but oak’s characteristics make it the ideal companion for winemaking. Here are a few reasons why:

  • It does not rot when in contact with moisture.
  • It can be bent without breaking (with a little help from of our friend, heat).
  • Its texture does not allow liquid to leak, but it does allow a little oxygen into the barrel. This helps to soften and give complexity and mouthfeel to the wine.
  • It adds flavor, tannin, and texture to wines

Origin of the Wood Matters

An oak tree may need up to 120 years to grow before being used for barrel making. It is said that from one oak tree a cooper can make one, or maximum two, barrels. Luxury item, right? There are more than 600 species of oak in the world, and three of them are commonly used for barrel making: two European species (sometimes called “French oak”) and one American species.

Barrels made with European oak are usually more expensive than those made with American wood. The difference in price is due to the percentage of usable wood, of which European oak has less. European oak has to be wedge split along its grain, while American oak can be split using a saw. This means that only 20 to 25 percent of a European oak can be used for barrel making, while 50 percent of an American oak can be used for the same purpose.

Just as with wine grapes, oak trees are also highly influenced by the climate and the soil. The same type of oak grown in different areas usually produces a different barrel quality. Trees that come from cooler climates have a finer grain than those grown in warmer ones. A finer grain allows less oxygen contact and usually means a subtle, more elegant oak influence on the wines.

Types of Oak

European Oak

  • Quercus Robur: As the name suggests, this type gives rough tannins, low aromas, and less elegance to wine. It’s mostly used for ageing spirits, for example Cognac.
  • Quercus Petraea: This is the higher-quality oak for winemaking. Because of its finer grain it gives lower tannins and is much richer in aroma components.

American Oak

  • Quercus Alba: This has a wider grain and grows faster than the European types. It gives much lower tannins, releases aromas quicker, and gives higher amount of lactones (which are the sweet notes—like vanilla, caramel, and baking spices—which you can taste in wine). Because of its wider grain, it allows for a more pronounced oxidation. This type of oak is usually used to age wine with high tannins because the oak will not add more tannins to the wine and the higher amount of oxygen contact will soften it.

Hungarian Oak

Hungary has two oak forests where most of the raw material for barrel making come from: Mecsek and Zemplén.

The Mecsek forest is in southern Hungary, surrounding the Szekszárd and Villány red-wine-making regions. It has fertile soil and a warmer climate than Zemplén. It is planted with both Quercus Robur and Quercus Petrae. The barrels made with oak from this forest usually give sweeter notes and a lighter flavor influence than those from the Zemplén forest.

In Hungary, the Zemplén forest usually gives the best oak for barrel making. The Zemplén hills surround the Tokaj region in northeastern Hungary, holding this forest which has rocky volcanic soil. The climate is colder, winters are longer, and the average altitude is higher than the Mecsek forest. This makes the trees grow slower, creating a tight grain—the secret of success!—allowing wines to mature slowly and longer in the barrel without being overly-oxidized. Of the oak in the Zemplén forest 95 percent is Quercus Petraea. It is believed that barrels made of Zemplén Quercus Petraea give wines silkier tannins in comparison to barrels from the same type of oak from, lets say, a French forest.

From Tree to Barrel

Usually oak trees are harvested in the winter because the trees have less sap so are easier to cut. After the tree is split, it is seasoned either in the open air or in the kiln. Seasoning in a kiln consists of drying the wood in an oven-like environment for a few months. Open air seasoning is considered to produce a higher quality barrel, and means the wood staves are left out in the open air from 24 to 36 months. The weather conditions—rain, sunshine, and even snow—will help remove some of the wood’s harsh tannins. The longer the seasoning takes, the better. The wood’s moisture goes from 70 percent to about 15 percent after the seasoning period. The wood then goes into the cooperage where the staves are pre-heated, toasted to the desired level, formed, bent, and polished … resulting in a brand new barrel!

To make a hybrid barrel—75 percent American oak and 25 percent French oak— the body is made of American oak and the heads of French wood. This way a winemaker has the possibility of having the two flavor profiles of the different oaks at the same time. The heads of the barrels can also be toasted, or not, depending on the winemaker’s preference.

For white wine making there is another option: steam bent barrels. This type adds the smallest amount of flavor to the wines, because steam is used instead of fire to shape the barrels.

What Oak Ageing Does To Wine, and Why

Oak barrels usually give a distinct taste to the wines they hold, with each oak type giving a different taste. The level of toasting, age of the barrel, and barrel size are the most important factors that determine the flavors that a barrel give to wines.

These are some of the aromas that come from oak barrel ageing:

  • Medium toasted American oak: coconut, vanilla, caramel, toast, roasted nuts, roasted coffee, or cocoa
  • Medium toasted French oak: cedar, cigar box, dark chocolate, nutmeg, allspice, or crème brulée
  • Medium toasted Hungarian oak: butterscotch, vanilla, clove, cinnamon, or toffee

The level of toasting on the wood is one of the most talked-about features of oak barrels. Toasting is the charring of the inside of a barrel with fire. There are several levels of toasting: light, medium, medium+, heavy, and toasted head. The level of toasting influences the quantity and type of flavors a barrel gives to the wines: the heavier the toasting, the stronger the oak flavor will be in the finished wine.

The age of the oak determines the quantity of flavor that a barrel gives to a wine. A new barrel will give about 70 percent of its flavor in the first year of ageing. During the second and third years of use the barrel can give some flavor. But after four years of use barrels don’t really influence the flavor profile of the wines anymore, only their texture and mouthfeel. Old barrels are used more as vessels and less as taste influencers.

The size of the barrels can vary dramatically depending on the region and style. The smaller the barrel, the bigger the influence it has on the wine’s flavor, texture and final profile. Some of the more common barrel sizes are:

International:

  • Barrique: 225 liters. Originally from Bordeaux, this has become one of the most common sizes. Its size was designed to suit shipping boats.
  • Piéce: 228 liters. This is the classic Burgundy style barrel. It is about the same size as Bordeaux’s, but is wider. This small difference makes it easier for winemakers to use the lees stirring technique commonly used in the region (battonage) and for carriage shipping, instead of boat shipping.
  • Hogshead: 300 liters. Most commonly used in Australia and New Zealand.
  • Puncheon: 500 liters. This bigger size makes it good for dry white wines.

Hungarian:

  • Gönci: 136 liters. The historical Hungarian barrel. Highly associated with Tokaji aszú wine making. This size gives the most pronounced oaky flavors to the wines and allows the highest amount of oxygen contact. For this reason, it is not widely used these days.
  • Szerednyei: 220 liters. Named after a historical Hungarian town, Szerednye/ Serednje, which is now located in Ukraine. This is the size of choice these days among Tokaj wine producers.

Cooperages in Hungary

In addition to the three important cooperages in Hungary, there are still several smaller family-run cooperages (mainly in the Zemplén region).

Established in 1851, Kádár used to be called Budapesti Kádár. It is partially owned by the French cooperage, Taransaud. Their stave mill is located in Erdőbenye, in the Tokaji region. Their annual production is around 6,000 barrels. They supply more than 400 wineries in 12 major winemaking markets.

Established in 1992, Trust Hungary is the biggest producer of oak barrels in the country, making two-thirds of Hungary’s barrels. Located in Szigetvár—in southwestern Hungary near the Mecsek forest—the company started as just a stave producer, only later also becoming also a barrel maker. It produces between 18,000 and 20,000 barrels annually, with only about 2,000 staying in Hungary. The rest are exported), mainly to the USA (about 10,000 a year), France, and China.

European Coopers, which was established in 1997, is located in Palotabozsók, near the Mecsek forest. It is partially owned by the Antinori, Gamba and Mazzei wine families. They produce barrels mostly for the Italian market.

Attila Hotyek‘s family has been making handmade barrels the traditional way in Erdőbénye for generations. He also makes his own wine and pálinka. Both his son and daughter are carrying on the tradition. (All of the photos in this post are from the Hotyek family’s cooperage!)

Miklóssy Kádár is a reputable operation in Erdőbénye. It makes barrels for Oremus in Tolcsva, amongst others.

As with its wines, Hungarian oak has a unique personality. But while the wines are no longer an undiscovered secret, Hungarian oak remains one of the best-kept secrets in the wine business.
