Riesling has a long history, and there are several written references to the variety dating from the 15th century, although with varying orthography. The earliest of these references dates from March 13, 1435, when the storage inventory of the high noble Count John IV. of Katzenelnbogen in Rüsselsheim (a small principality on the Rhine, close to today’s Rheingau) lists “22 ß umb seczreben Rießlingen in die wingarten” (“22 shillings for Riesling vine cuttings for the vineyard”). The spelling Rießlingen is repeated in many other documents of the time. The modern spelling Riesling was first documented in 1552 when it was mentioned in Hieronymus Bock’s Latin herbal. A map of Kintzheim in Alsace from 1348 contains the text zu dem Russelinge, but it is not certain that this reference is to the grape variety. However, in 1477, Riesling was documented in Alsace under the spelling Rissling. In Wachau in Austria, there is a small stream and a small vineyard both called Ritzling, which are claimed locally to have given Riesling its name. However, there seems to be no documentary evidence to back this up, so this claim is not widely believed to be correct.
Riesling wines are often consumed when young, when they make a fruity and aromatic wine which may have aromas of green or other apples, grapefruit, peach, gooseberry, honey, rose blossom or cut green grass, and usually a crisp taste due to the high acidity. However, Riesling’s naturally high acidity and range of flavours make it suitable for extended aging. International wine expert Michael Broadbent rates aged German Rieslings, some hundreds of years old, highly. Sweet Riesling wines, such as German Trockenbeerenauslese are especially suited for cellaring since the high sugar content provides for additional preservation. However, high quality dry or off-dry Riesling wine is also known to have not just survived but also been enjoyable at an age exceeding 100 years.
The most expensive wines made from Riesling are late harvest dessert wines, produced by letting the grapes hang on the vines well past normal picking time. Through evaporation caused by the fungus Botrytis cinerea (“noble rot”) or by freezing, as in the case of ice wine (in German, Eiswein), water is removed and the resulting wine offers richer layers on the palate. These concentrated wines have more sugar (in extreme cases hundreds of grams per litre), more acid (to give balance to all the sugar), more flavour, and more complexity. These elements combine to make wines which are amongst the most long lived of all white wines. The beneficial use of “noble rot” in Riesling grapes was discovered in the late 18th century at Schloss Johannisberg. Permission from the Abbey of Fulda (which owned the vineyard) to start picking Riesling grapes arrived too late and the grapes had begun to rot; yet it turned out that the wine made from them was still of excellent quality.
Fruit wines are fermented alcoholic beverages made from a variety of base ingredients (other than grapes); they may also have additional flavors taken from fruits, flowers, and herbs. This definition is sometimes broadened to include any fermented alcoholic beverage except beer. For historical reasons, mead, cider, and perry are also excluded from the definition of fruit wine. Fruit wines have traditionally been popular with home winemakers and in areas with cool climates such as North America and Scandinavia; in Africa, India, and the Philippines, wine is made from bananas.
Fruit wine can be made from virtually any plant matter that can be fermented. Most fruits and berries have the potential to produce wine. Few foods other than grapes have the balanced quantities of sugar, acid, tannin, nutritive salts for yeast feeding and water to naturally produce a stable, drinkable wine, so most country wines are adjusted in one or more respects at fermentation. However, some of these products do require the addition of sugar or honey to make them palatable and to increase the alcoholic content (sugar is converted to alcohol in the fermentation). Two commonly produced varieties are elderberry wine and dandelion wine. Tainted elderberry wine is the beverage used to commit murders in Joseph Kesselring’s play and Frank Capra’s film adaptation Arsenic and Old Lace. (A wine made from elderberry flowers is called elder blow wine.
The amount of fermentable sugars is often low and need to be supplemented by a process called chaptalization in order to have sufficient alcohol levels in the finished wine. Sucrose is often added so that there is sufficient sugar to ferment to completion while keeping the level of acidity acceptable. If the specific gravity of the initial solution is too high, indicating an excess of sugar, water or acidulated water may be added to adjust the specific gravity down to the winemaker’s target range.
Many kinds of fruit have a natural acid content which would be too high to produce a savory and pleasant fruit wine in undiluted form; this can be particularly true, among others, for strawberries, cherries, pineapples, and raspberries. Therefore, much as to regulate sugar content, the fruit mash is generally topped up with water prior to fermentation to reduce the acidity to pleasant levels.
Unfortunately, this also dilutes and reduces overall fruit flavor; on the other hand, a loss of flavor can be compensated by adding sugar again after fermentation which then acts as a flavor enhancer (known as a back-sweetener), while too much acid in the finished wine will always give it undesired harshness and poignancy. Many fruit wines suffer from a lack of natural yeast nutrients needed to promote or maintain fermentation. Winemakers can counter this with the addition of nitrogen, phosphorus and potassium available commercially as yeast nutrient. In the opinion of one wine writer fruit wines often do not improve with bottle age and are usually meant to be consumed within a year of bottling.
Wine is regulated by regional, state, and local laws. The laws and their relative rigidity differ for New World and Old World wines. Old World wines tend to have more stringent regulations than New World wines. Various wine laws, however, may include appellation-based regulations that cover boundaries as well as permitted grape varieties and winemaking practice-such as the French Appellation d’origine contrôlée (AOC), Italian Denominazione di origine controllata (DOC), Spanish Denominación de Origen (DO) and Portuguese Denominação de Origem Controlada (DOC). In some New World wine regions, such as the United States and Australia, the wine laws of the appellation systems (American Viticultural Area (AVA) and Australian Geographical Indication (GIs)) only pertain to boundary specifics and guaranteeing that a certain percentage of grapes come from the area listed on the wine label.
