Visitors to Australia’s Barossa Valley can bottle their own red by visiting Penfolds’s tasting room and taking the Make Your Own Blend tour. The final stop is the winery lab, where guests can try their hand at blending Grenache, Shiraz and Mourvèdre, then bring the bottle home—or to dinner that night ($35; Tanunda Rd., Nuriootpa; 011-61-8-8568-9408 or penfolds.com).
