The Reichsgraf von Kesselstatt Winery is located at Marienlay Castle in Morscheid on the Ruwer. Previously, the wines were produced in the well-known Palais Kesselstatt, in the heart of Trier city center directly opposite Trier Cathedral, before the winery moved to the Ruwer in 1999. Today, the Palais is the winery's own wine tavern and a popular restaurant. The winery now cultivates a total of 46 hectares of vines, almost equally distributed across all three river valleys (Mosel, Saar, Ruwer) – a unique feature, as, besides Kesselstatt, only the Bischöfliche Weingüter in Trier own vineyards in all three river valleys. Listing all the winery's sites would simply take too long, as the portfolio boasts one top site after another. It includes a total of 11 VDP Grosse Lagen, which are among the best sites on the Mosel, Saar, and Ruwer. These include legendary sites such as Wehlener Sonnenuhr, Piesporter Goldtröpfchen, Kaseler Nies'chen, Ockfener Bockstein, and Scharzhofberger. A unique portfolio of sites that is unparalleled! In addition to Riesling, which accounts for the largest share at 96%, Weißburgunder (Pinot Blanc) is also cultivated here. Since July 2020, the winery has been managed by Dr. Karsten Weyand, an internationally respected oenologist. Alongside him is the experienced cellar master Wolfgang Mertes, who has been responsible for the production of Kesselstatt wines since 2005. In the same year, the winery became a member of the Association of German Prädikat Wine Estates (VDP). Together, they are working to further improve wine quality in the coming years. The winery placed a special focus on producing dry premium wines over 30 years ago, at a time when predominantly sweet wines were produced on the Mosel, Saar, and Ruwer. The then managing director and owner, Annegret Reh-Gartner, already saw the potential for producing great, dry Rieslings. She passionately fought for their recognition both nationally and internationally, because the light, elegant, and mineral wines had a difficult time in an era when the relevant trade press primarily awarded top marks to powerful and high-alcohol 'power wines.' Ms. Gartner proved to be right, as her mature dry wines today, with 20 years or more of bottle aging, present themselves excellently and were true forerunners of today's Grosses Gewächs wines. The winery has received numerous awards from the trade press and is rated with three grapes in Gault & Millau.

The Reichsgraf von Kesselstatt winery is one of the oldest wineries in the region and in all of Germany. Since the first documented mention of the purchase of "vineyards" for the knightly family of Kesselstatt in 1349, the winery looks back on a history of over 670 years. The year 1787 was decisive, when the last Archbishop and Elector of Trier, Clemens Wenzeslaus, ordered the planting of Riesling and Elbling, which he believed had better characteristics, instead of the "objectionable Rhenish vines," which in his opinion yielded inferior grapes with too much acidity. He thus went down in history as the "Riesling Prince" and ensured the widespread cultivation of Riesling in Mosel-Saar-Ruwer. Between 1854 and 1889, the von Kesselstatts were able to purchase four former Maximiner monasteries along with their lands on the Mosel, Saar, and Ruwer. The top sites of Josephshof (Graach - Mosel), Domklausenhof (Piesport - Mosel), Abteihof (Oberemmel - Saar), and St. Irminenhof (Kasel - Ruwer) still form the foundation of the winery's unique portfolio of sites today. In 1978, Günther Reh, a successful entrepreneur from Leiwen who had made a name for himself primarily in the sparkling wine industry with his company Faber, acquired the winery. His daughter Annegret was immediately enthusiastic about the traditional winery and took over the business in 1983 after completing her viticulture apprenticeship – a novelty, as the wine world at that time was dominated by men and a woman as winery manager seemed almost unthinkable. However, with her great passion for Riesling, eloquence, and charisma, she quickly made a name for herself in the industry and helped the winery achieve great recognition in Germany and around the world. Hardly anyone campaigned internationally for German Riesling as much as she did! One of her most important tasks at the winery was the gradual reduction of the vineyard area. In the mid-1980s, the winery still cultivated over 100 hectares of vines! The long travel times to the parcels scattered across all three river valleys were no longer efficient, and so the vineyard area was gradually reduced to today's 46 hectares, which significantly benefited the quality of the individual wines! With the construction of the new press house, Annegret Reh-Gartner had perfectly positioned the business for the future after 33 years, before she passed away far too soon in 2016.

In the vineyard, the Reichsgraf von Kesselstatt team consistently employs yield-reducing measures such as grape splitting and green harvesting in late summer. Defoliating the grape zone in early autumn ensures that the ripening grapes are well-ventilated and remain healthy for as long as possible, which is crucial, especially for the production of great dry wines. Many of the best vineyards feature old Riesling vines, some still ungrafted. In autumn, the grapes are selectively hand-picked into small bins to transport them to the new press house as undamaged as possible. There, the grapes are gently processed on state-of-the-art presses and fermented in stainless steel tanks in the cool estate cellar, preferably with natural yeasts. With such a multitude of top sites across all three river valleys, the challenge for cellar master Wolfgang Mertes is to transfer the terroir of each individual vineyard as authentically as possible into the bottle, making the wines' unique origin discernible by scent and taste. Most wines remain on their fine lees until shortly before bottling, which gives them a fine silky texture and aromatic depth. Some of the "Große Gewächse" (Grand Cru) wines mature in large wooden barrels to give them even more structure and expressiveness.

The Kesselstatt portfolio is divided into four lines. The VDP.Gutsweine (estate wines) can fundamentally contain both own and purchased grapes from various vineyards along all three rivers and are uncomplicated, refreshing wines for everyday enjoyment. The VDP.Ortsweine (village wines) and VDP.Grosse Lage (grand cru) wines are divided into three collections: Mosel, Saar, and Ruwer, which are clearly indicated on the labels. A typical characteristic of Kesselstatt wines is their excellent suitability as food companions. They particularly benefit from a few years of aging, as over the years, the wines increasingly reveal the unique terroir of the individual sites and develop a fine richness and aromatic depth.
