The wine spa—a quiet niche in the world of pampering—is making a big splash with Steven Holl's sensational new LOISIUM WINE & SPA RESORT in the Kamptal region of Austria, an hour from Vienna. Inside, green glass tiles call to mind bottles of the area's famous Grüner Veltliner. In the restaurant, a wine-red fireplace is the center of attention. The focal point of the spa menu is the 60-minute Barrique Cuvée scrub, bath, and massage. From $210 to $355; treatments from $40; 43-2734/77100; www.loisiumhotel.at.
