Roald Wine Company

About Us


Roald Wine Company came into being due to Greg Nelson's passion for wine and his appreciation for his father. Roald Nelson has always been a positive influence with many exemplary qualities. These qualities became the standard for the expressive wines that Greg is crafting.

The road to winemaking was a winding one. It led to work in Alaska, travel abroad, an affinity for the peregrinations and jazz influences of Jack Kerouac, as well as research in the laboratory.

The spirit of exploration and the qualities of Roald Nelson are reflected in the wines. We invite you to visit our tasting room and try them.


Greg Nelson

Greg was born in Indiana and went to high school in New York State near Buffalo. While attending college in Madison, Wisconsin, he frequented a wine shop where he was introduced to wines from Europe and California. He developed a passion for wine, and wine became part of daily life. Subsequently, he earned a PhD in Biology at UC San Diego for discovering the sweet taste receptor and the umami taste receptor. Accolades include an appointment as a Beckman Scholar with the Arnold and Mabel Beckman Foundation, a Hewitt Fellowship, and publication in the scientific journals Nature and Cell. While in San Diego, Greg became interested in the biology and the process of winemaking, and his first wine was a good zinfandel. For the harvest following that first fermentation, he moved to Sonoma County to work in wineries. He gained experience in both the cellar and the lab at multiple wineries, including Ramey and Martinelli, and assisted with founding Conarium Wines before starting Roald Wine Company.
