Host Lynn Elmhirst tastes and sips her way through 4 countries sailing aboard the Viking Sygyn along one of the main maritime transportation routes in Europe. She learns how to make Switzerland's famous cheese fondue, meets a female winemaker in France's Alsace region, visits the 'Cathedral of Wine' at the oldest Riesling winery in the world, where there's a tasting by candlelight! On board the river cruise ship, she learns how to make 'spirited' local Rudesheim coffee, toasts an Oktoberfest dinner and wonders at the sight of over 30 castles along the riverbanks of the 'Romantic Rhine.'
