The Wine House Hotel - Quinta da Pacheca

Sleeping inside a wine barrel is less ridiculous than it sounds: Quinta da Pacheca converts decommissioned casks into snug pod cabins with terraces that look out over Douro Valley vineyards. The manor house also has traditional rooms for those who prefer walls that weren't recently holding Touriga Nacional. A Michelin Key property, it runs tastings, tours, cooking classes, and vineyard picnics, so the itinerary more or less writes itself before you've unpacked.
