Bob is passionate about wine. He has toured many of the world's renowned wine regions, tasted countless bottles, and earned the right to be considered a wine aficionado among his friends. But what happens when he is put to test by assisting in the harvest of 17 acres of precious grapes, for the maker of Germany's finest Rieslings? Intense periods of backbreaking work will test Bob's patience and skill, as well as his body. Prüm's grapes are harvested late in the season, when the air has already turned crisp. While the physical efforts help warm the bodies of pickers, so does the glühwein - heated, spiced wine, that they are sent as a reward (or a bribe?) during their long shifts. This and the gourmet food prepared as an incentive to the workers will help get Bob through the severe labour. His reward? Delicious insights into the intimidating world of wine and the knowledge to back up his strong opinions.
