The Revival of Riesling

By W Peter Hoyne

Rieslings have been misunderstood and overlooked for decades. It is a grape varietal that has a refreshing, everyday appeal yet it is immediately thought of as a semi sweet alternative to dry white wine. In reality, it is a versatile grape that can assume a wide spectrum of diverse flavor profiles ranging from crisp mineral and lemon-grass-driven acidity to delicate floral attributes with hidden fresh fruit notes of green apple, citrus and white nectarine. If you opt for more exotic tropical notes, you can find them in late-harvest renditions. Either way, you have a wealth of options and countries to choose from that are sure to offer you an elegant and harmonious white that can find affinity with Mediterranean cuisine, balance the heat in spice-inspired recipes or will glisten on its own during a warm summer day.

Riesling’s official day of origin is recognized as March 13, 1435. This birthdate recognizes the first evidence of this grape in the cellar log of Count Katzenelnbogen near Rheingau, Germany. In the 16th century there was a push for higher quality Rieslings and by the 1850’s Riesling wine had achieved notoriety with pricing at the same level as the wines of Bordeaux and Champagne. World Wars led to the decimation of vineyards and a lack of international demand for German wine. Production of Liebfraumilch, German for “Our Lady’s Milk” originally derived from vineyards surrounding the Church of Our Lady in Worms, Germany. Although its stoic history can be traced back to 1745, it achieved popularity in 1923 within Germany when Peter Sichel launched Blue Nun. It became fashionable within the US and the UK between the 1950’s and the 1980’s when nearly two million cases were exported. Later, it became recognized as a more generic, regionally blended wine which lead to its decline along with the perception of quality German wine.

Reform of German wine laws occurred in 1971 with a new quality oriented classification. The two most important categories established by this system were Qualitätswein (quality wine) and Qualitätswein mit Prädikat or Prädikatwein (quality wine with a special attribute). This stringent classification framework categorized wines according to their natural ripeness level at harvest. The ascending levels of sweetness include Kabinett, Spätlese, Auslese, Beerenauslese, Trockenbeerenauslese and Eiswein.

These wines must adhere to a minimum alcohol level and need to originate from one of the 13 German wine-growing districts. They can only be made from legally permitted grapes in Germany and the addition of sugar in Prädikatwein is prohibited. The framework for Qualitätswein was further defined in 2021. Later wines with the term, Trocken (dry) and Halbtrocken (half-dry) were introduced. Today, nearly 48% of German wines are considered to be dry by European Union definitions. The VDP eagle logo atop the capsule further signifies wines from Germany’s finest vineyard sites.
Germany's wine regions are predominantly situated along river valleys such as the Rhine, Mosel, and Nahe. These areas benefit from a temperate climate that balances warm summer days and cool nights, which is essential for slow ripening of the grapes and developing complex flavors with vibrant acidity. The acidity provides the backbone for the ripeness in the wines. Riesling is a transparent grape with an innate ability to be reflective of the varied soils where it is grown revealing a rich tapestry of flavors and aromas. In the Mosel Valley, Rieslings can express striking floral aromas with green apple and white peach elements with an underlying wet mineral or crushed limestone-driven texture. Within the Rhine, Rieslings exhibit a fuller body with stone fruits layered with baking spices.

One of Riesling’s most remarkable attributes is its aging potential. The high acidity and natural sugars allow Rieslings to develop gracefully over decades. With age, Rieslings transform, developing complex tertiary aromas of petrol, honey, and dried apricot, while retaining their natural fresh acidity.

Rieslings' revival and increased notoriety broadened in the 1990’s and in 2001 as Germans spent more money on wine than beer. Today, a younger generation of German winemakers are carrying on family legacies with organic and biodynamic farming with a close eye on tradition.

Rieslings’ rise in Alsace, France dates back to 1477 when it was part of the German Holy Roman Empire. The wine regions of Alsace are situated in the northeastern corner of France directly across the Rhine River bordering Germany’s Baden wine growing region. The vineyards run in a narrow swath from north to south. Since 1681, Alsace has changed hands multiple times with Germany. It was officially annexed to France for the last time in 1918 following the Treaty of Versailles. While the national language is neither French nor German, but Alsatian, the regional cuisine closely resembles that of Germany and the Riesling wines are distinctly Alsatian.

Nearly 90% of Alsace wine production is white with Riesling being the dominant grape varietal. Nestled between the Vosges Mountains and the Rhine River, Alsace offers a terroir that is as diverse as it is enchanting, creating the perfect canvas for Riesling.
The Vosges Mountains play a crucial role, shielding the vineyards from excessive rainfall and creating a rain shadow effect that results in one of the driest climates in France. Alsace, with its patchwork of soil types and microclimates, provides an extraordinary environment for viticulture. The region's geology is a mosaic of granite, limestone, schist, clay, and sandstone, each contributing to the nuanced characteristics of its wines.

Rieslings from Alsace have a full-bodied texture with an aromatic intensity and dried fruit characteristic that is notably different from their lighter-weight counterparts in Germany. Alsatian Rieslings are mouth-filling and dry with a juicy, stone peach and white flower personality complimented by fresh acidity.

Alsatian Rieslings can be designated as Alsace AOC or Alsace Grand Cru wines. The vineyards with the best terroir and restricted yields are designated as Grand cru parcels of which there are 51 sites. Late-harvested wines with higher natural residual sugars are labeled as Vendange Tardive (VT), “late harvest” and Sélection de Grains Nobles (SGN), “selection of noble berries.”

In the verdant heart of New York State, between Rochester and Syracuse, lies the Finger Lakes region. It unveils an enchanting landscape of glacial lakes, rolling hills, and vine-clad slopes. Finger Lakes, named for its eleven long, narrow lakes resembling fingers, is a testament to the power of glacial activity. These deep, cold lakes play a crucial role in moderating the climate, providing a unique microclimate that is ideal for viticulture. The steep slopes that rise from the lakeshores offer excellent drainage and a variety of soil compositions—ranging from shale and limestone to gravel and clay. This is a land where Riesling reigns supreme with wines that speak of the ancient soils and the innovative spirit of its winemakers. The diversity of this terroir allows Riesling to express itself in a myriad of ways with each vineyard site imparting its own distinct character to the wine.

New York has an influential role in the evolution of winemaking dating back to 1647 when early Dutch colonists and French settlers planted the first European varietals and vineyards in the Hudson Valley. Afterward, it wasn’t until 1829 when Reverend William Bostwick planted vines in his rectory garden in the Finger Lakes region.

Early pioneers who blazed a path in this region included Dr. Konstantin Frank, a Ukrainian immigrant with a Ph.D in viticulture who worked at Cornell University and was the first to introduce Riesling to this region. Hermann J Weimer was born into a winemaking family in Bernkastel, Germany. His father was adept in grafting German Riesling to American rootstock. Hermann moved to New York in 1965 and was inspired by the achievements of Dr. Frank, planting a vineyard on a parcel of land on Seneca Lake cultivating Riesling and Chardonnay.

Riesling has since become the most planted varietal in the Finger Lakes with 950 acres under vine and nearly 150 wineries in the region. The Finger Lakes AVA was established in 1982 and is separated into two sub-AVAs, the Cayuga Lake AVA and the Seneca Lake AVA.

In Australia, the first cuttings of Riesling were imported by William Macarthur in 1838. In the 1960’s Riesling was the top white grape varietal planted in Australia and its total plantings are second only to Germany. The Claire Valley in South Australia is considered one of the premium wine growing regions for Riesling, followed by the Eden Valley. The majority of today’s Riesling from Australia has a dry, mineral-like expression with overtones of yellow citrus.

Riesling is not just a grape; it is a reflection of Germany’s rich winemaking heritage and influence around the world. It is a canvas of the terroir and a testament to the winemaker’s artistry. Its versatility, complexity, and ability to age make it a favorite among wine lovers and collectors worldwide. Whether enjoyed young and fresh or aged and intricate, a glass of Riesling is a journey through time and place, a celebration of the vine, and a tribute to the enduring allure of early German viticulture. Cheers to Riesling, the crown jewel of white wine!
