As a native of Bernkastel, Germany who emigrated to the Finger Lakes in the 1960s, Hermann J. Wiemer was uniquely qualified to help establish and create a wine region now known for its Riesling identity. His mother’s family had been making wine in Germany’s Mosel Valley for more than 300 years. His father, a skilled nurseryman, had been in charge of the Agricultural Experiment Station in Bernkastel and was responsible for restoring vines in the Mosel region after WWII. As a result, he recognized the importance of grafting vinifera on American rootstock. Ultimately, this conviction led Hermann’s father to convince Dr. Thanisch – who maintained the most famous Riesling vineyard in the world – to graft Mosel Rieslings onto American rootstock.
In 2003, Hermann’s long-term apprentice Fred Merwarth took charge of winemaking and vineyard management. Fred’s talent and ambition brought fresh energy and vision to the winery, placing it on a new trajectory. In 2007, Hermann officially retired, handing over the winery to Fred, who partnered with his university friend, Swedish agronomist Oskar Bynke, to carry on Hermann’s legacy.
