Engelberg (grand cru)

Slope below the Scharrach hill

Alsace Grand Cru ‘’Engelberg’’ is a French white wine produced in the Bas-Rhin department, in Alsace.

On the Alsace Wine Route, Engelberg is located between the communes of Dahlenheim and Scharrachbergheim-Irmstett. It is one of the fifty-one grands crus of the Alsace region, each enjoying its own appellation but sharing the same Alsace Grand Cru specifications (with more stringent constraints than for the Alsace appellation in general).

History

In 1983, Engelberg was not one of the twenty-four lieux-dits selected to become the geographical names of the Alsace Grand Cru appellation. It joined the list in 1992.

There have been some changes since then: the decree of 1 March 1984 regulates the terms vendanges tardives and sélection de grains nobles within the appellation and the decree of 24 January 2001 reduces yields and offers the option of modifying the specifications of each denomination (each vintage) after consulting the local wine syndicate.

In October 2011, all the grands crus of Alsace went from the status of geographical denominations within the same appellation to that of separate appellations sharing the same specifications.

Etymology

The name is made up of the German word Engel meaning 'Angel/s' and the word Berg meaning mountain, meaning 'mountain of angels'.

Geology

The area is marked by Muschelkalk lime.

Character

The wines here - particularly the Riesling - are structured and lean, a character attributed to the limestone and pebbles.

Climatology

To the west, the Vosges protect the hillside from wind and rain. The prevailing westerly winds lose their moisture on the western slopes of the Vosges and reach Alsace in the form of foehn winds, dry and warm. Precipitation is therefore particularly low.

As a result, the climate is much drier (Colmar is the driest station in France) and a little warmer (with an average annual temperature 1.5 °C higher) than would be expected at this latitude. The climate is continental and dry with warm springs, dry and sunny summers, long autumns and cold winters.

The vineyard is located on the side of a hill, between 250 and 300 metres high; on the slopes of Mont Scharrach and facing due south, west of the village of Dahlenheim. The area of the vineyard is 14.80 hectares.

Climate

The appellation shares features with Alsace in general, namely the protection from wind and rain provided by the Vosges mountains. The winds lose their humidity as they pass eastward over the hills, with dry and warm Foehn wind passing over the vignoble, leading to very low rainfall.

The nearest meteorological station to Kintzheim is the Entzheim station. Values between 1961 and 1990 are as follows:

Grape varieties

Wines corresponding to the Appellation d'Origine Contrôlée Alsace Grand Cru followed by the geographical name (place name) Altenberg de Bergheim must be produced with the following grape varieties, either as a single variety or as a blend: Riesling, Pinot Gris, Gewurztraminer or one of the Muscats (Muscat Ottonel, Muscat Blanc à Petits Grains, or Muscat Rose à Petits Grains).

Gewurztraminer (meaning "aromatic traminer" in German) is the most cultivated grape variety in Engelberg. It is a pink grape variety with orange or purple berries. This close relative of Savagnin and Savagnin Rose (called Klevener de Heiligenstein in Alsace) is rather vigorous, produces large yields and gives better results on marl or limestone soils than on granite or schist soils.

Riesling is a grape variety with late budburst and late ripening, requiring hillsides well exposed to the sun, whose harvests can take place around mid-October. On the other hand, it resists winter frosts well.

Pinot Gris (called Grauburgunder, "Gray Burgundian" in German, "Malvoisie" in Valais or Pinot Grigio in Italy) is a fragile grape variety and ripens quite early. It comes from a mutation of Pinot Noir and is therefore of Burgundian origin, where it is called "Pinot Beurot". It gives better results on soils composed of limestone gravel provided they are well drained thanks to a hillside exposure.

Muscats are rarely grown, either in the entire Alsace vineyard or in plots classified as Grands Crus. Muscat Blanc à Petits Grains, also called "Muscat d'Alsace", is originally from Greece; it has been grown in Alsace since at least the beginning of the 16th century. It is rather early. Muscat Ottonel is more recent, discovered in the 19th century in the Loire Valley before arriving in Alsace in the middle of the century. Ottonel is a hybrid of Chasselas, so it ripens even earlier than Muscat d'Alsace.

Cultivation practices

The vines are trained high to protect them from frost, with the foliage espaliered; the height of the trellised foliage cannot be less than 0.675 times the spacing between the rows. The pruning of the vine must be done in single or double guyot with a maximum of ten buds per square meter of ground surface for the Gewurztraminer grape variety and eight buds per square meter of ground surface for the other grape varieties.

The average maximum load per plot is set at 10,000 kilograms of grapes per hectare.

Yields

The yield limit for the entire Alsace Grand Cru appellation is set at 55 hectoliters per hectare, with a maximum yield of 66 hectoliters per hectare which is much lower than the 80 hectoliters authorized by the Alsace appellation. The actual yield of the entire appellation (the 51 Alsatian crus) was 50 hectoliters per hectare on average for the year 2009. Although this is well below the average yields of the Alsace area in general, it is a yield within the French average.

The grands crus of Alsace must be harvested by hand.

Wines

Alcoholic strengths

The grapes harvested must have a minimum average natural alcoholic strength by volume of 12.5% for the Pinot Gris and Gewurztraminer grape varieties and 11% for Riesling and the Muscats. Wines from a blend have a minimum average natural alcoholic strength by volume of 12%.

Any single batch of grape harvests with a sugar content of less than 193 grams per litre of must for the Pinot Gris and Gewurztraminer grape varieties and 168 grams per litre of must for the other grape varieties are not considered to be at good maturity. When authorisation for chaptalisation (enrichment with sugar for fermentation) is granted, the increase in the minimum average natural alcoholic strength by volume cannot exceed 1.5% vol. On the advice of the union of producers of the vintage, the regional committee of experts of Alsace wines can propose annually to the national committee of wines and spirits of the National Institute of Appellations of Origin, for the name and for each grape variety, a minimum average natural alcoholic strength higher and a sugar content of the unit batches higher than those mentioned above, as well as a maximum chaptalization lower than the rate mentioned above.

Vendanges tardives and selections des grains nobles

Vendanges tardives wines (Late harvest wines) refer to wines made from grapes whose harvest has been delayed to allow them to overripen, resulting in wines rich in sugar and alcohol, with more powerful and often mellow tastes. According to the law, the must must have at least 243 grams of sugar per litre if it is Gewurztraminer or Pinot Gris (or 14.4% of potential alcohol), or at least 220 grams of sugar per liter if it is Riesling or Muscat (or 13.1% of potential alcohol); no chaptalization is allowed. As for selection des grains nobles, this is a wine made from grapes harvested by successive selective sorting of the grains affected by noble rot (the fungus Botrytis cinerea), which gives even more concentrated, sweeter wines.

Vinification and aging

The grands crus of Alsace must be harvested manually. On the day of the harvest, upon arrival at the winery, the grapes are crushed and pressed to separate the must from the grape pomace. For this work, pneumatic presses are gradually replacing horizontal presses with plates. Then the pomace is put into a vat for settling, which is the drawing off of the juice without the lees, either by filtering or by decanting while waiting for them to settle at the bottom of the vat.

Alcoholic fermentation begins under the action of indigenous yeasts or selected yeasts introduced during the yeasting: this operation transforms the sugar in the grapes into alcohol. Controlling the fermentation temperature using a refrigeration system allows the aromatic potential of the product to be expressed. Once fermentation is complete after a month, the wine is drawn off to remove the lees. Malolactic fermentation is generally not carried out, blocked by sulfiding to preserve the acidity of the wine. The latter can be stored in vats to prepare it for bottling or aged in oak barrels or tuns.

Bottling

Alsace wines must be bottled only in flutes, i.e. bottles of the "Rhine wine" type of 75 centiliters, regulated by several decrees.

Labelling

Throughout the Alsace vineyards, wines are most often identified by their grape variety(ies): Riesling, Gewurztraminer, etc. This mention dominates the label even if it is optional.

When the Alsace Grand Cru appellation was created, the aim was clearly to promote the terroir. The mention of the grape variety is not obligatory and it is possible to put the name of the denomination in larger characters than that of the grape variety. So several mentions on the bottle label are possible, either simply the name of the appellation and the geographical name (Alsace Grand Cru Brand), or with in addition a mention of grape variety (Riesling, Pinot Gris, Gewurztraminer or Muscat), to which can be added the terms selection des grains nobles or vendanges tardives, as well as the name of a place name within the name:
