Life's too short for mediocre wine, so try a few of the delicious sorts on offer at Emrich-Schonleber. Set aside some time to learn about the winemaking process, from the pressing and fermentation to the aging of the product.
You'll have no end of sightseeing choices in Monzingen. Emrich-Schonleber is a great place to start here, but there are loads of other fine sights to consider. Malteserkapelle, Rhineland-Pfalzisches Open Air Museum, and Barfußpfad Bad Sobernheim are not far from the wine-making establishment and will fill in your day nicely.
