At the foothills of the Hornisgrinde Mountain in the Northern Black Forest, just outside of the wine-growing village of Sasbachwalden in Germany, there’s a tiny winery with an accommodation setup simply named Schlafen im Weinfass (“sleeping in a wine barrel”). Visitors can spend the night in one of eight 8,000-liter wine barrels that have been fitted with windows and all the accoutrements of comfortable living, including a bed, a modern bathroom, and a garden patio overlooking the vineyards. The barrels have indoor heating, and are available to reserve year-round. Guests get two wine barrels to themselves, one for sleeping in, and another with a living space and eco-toilet. Dinner and breakfast baskets are prepared by the Wild family, who own the vineyard and its vinous lodging places.
