Wine and beer tourism is booming, as travelers seek out emerging wine regions and destinations with thriving microbrewery scenes. In Europe, the tradition of producing both libations goes back centuries and continues to evolve. During Avalon’s Blue Danube Discovery for Beer Enthusiasts itinerary, you’ll be treated to onboard beer workshops, lectures and tastings highlighting regional brews, and a tour of a family brewery in Vienna. (Plus, in your down time, you can go tavern-hopping in port cities like Prague and Budapest.) If wine is more your drink of choice, the Rhine & Rhone Revealed for Wine Lovers cruise through Germany and France is led by a Master of Wine, who will share his expertise during onboard events pairing wine with chocolate, cheese, and multi-course meals. In between, you’ll take in the sights in Cologne, Koblenz, Lyon, and Avignon.
