As of my last knowledge update in January 2022, I don't have specific information about the "Schloss Koblenz Riesling Trocken 1x750 ml" product. To get the most accurate and up-to-date information, including availability, pricing, and specific details about this particular Riesling, I recommend checking with local wine retailers, the winery's official website, or contacting the winery directly.
Wine availability can vary based on location, and new vintages or products may have been released since my last update. If you have specific preferences or are looking for a particular vintage, contacting the winery or local wine merchants would be the best way to obtain the information you need.
