Will you have a car, or traveling by train?
We stayed at the Weingut Reis-Kroth in the village of Briedel on the Mosel in 2010. The Weingut has two guest rooms with ensuite bathrooms, a wonderful wide veranda overlooking the river below, and a great morning breakfast buffet. They also have a couple of rental bikes you can tour along the bike path by the river, a disused railway bed.
The ground floor of their home is the winery, parking for his small tractor and farm cart, a good sized modern wine press. Further back under what is their back patio, are the holding tanks, fermentation tanks, juice holding tanks. In the front is a bottling table with a hand corking machine, boxes of empty bottles, sheets of labels ready to be pasted on the bottles, and boxes of finished product. Naturally, there is a wine list in your room, along with a cork screw and wine glasses. Anytime you want one, just let them know and they'll fetch one up. Mostly Rieslings, Trocken and Halbtrocken. Nothing was more than 4 EUR a bottle.
His vines are on the hillside out side of town, and like all the other winemakers, he commutes to his vines. We visited in September after harvest, and there were many wine festivals up and down the valley that time of year.
Having said all that, a word of warning. Frau und Herr Reis-Kroth do not speak a lick of English. I was able to speak with Frau Reis-Kroth a little in a form of grammarless German, and she replied slowly as to a small child and I was able to understand her. But Herr Reis-Kroth always reverted to the universal "If they don't understand you, talk louder." But he was very proud of his operation and can rattle of the tank capacities in kiloliters, and the tons per hour capacity of his wine press. So ask and they'll give you the nickel tour of the winery. Your husband is a wine maker, so every thing will be familiar.
Weingut Reis-Kroth is easy to get to by car, but my wife and I were traveling "Rick Steves" style by train with small rollerboards and back packs. So we arrived at Bullay by train, just a couple of stops past Cochem where the rail line peels away from the river. From there we took a bus to Briedel, passing through Zell, home of Zeller Schwarze Katz wine and got off at a bus stop on the highway, walked down a flight of steps and walked about a half mile through town. I see now with careful planning by getting the right bus at the right time, could get a bus just a short walk away.
