Kirk Venge - B Cellars Master WinemakerKirk Venge

B Cellars Master Winemaker



B Cellars’ master winemaker Kirk Venge comes from a long lineage of winemaking.  Kirk is the protégé son of Nils Venge, a legendary Napa Valley winemaker whose wines consistently score above 90 points in Robert Parker’s Wine Advocate and other prestigious wine journals.  His deep family roots in viticulture and his passion for the industry that ensued led him to be named one of the top twenty young winemakers in the world by Food & Wine magazine.  Kirk’s heritage, love for winemaking, and unparalleled paternal tutelage have all provided him with a foundation bound for success in the wine industry.

Prior to B Cellars, Kirk worked at Mumm’s Napa Valley for five harvest seasons and one season at Rapaura Vintners in Marlborough, New Zealand.  In 1999, Kirk dove in head first and launched his own venture, Venge Vineyards, where his quest for doing something in his own right was realized.  His hard work paid off at Venge; you can taste his perfectionism and philosophy of “making wine in the vineyard” in each and every bottle.

At B Cellars, Kirk’s unmistakable commitment to his craft is apparent.  He works hand-in-hand with all of the vineyards with which B Cellars has become aligned, and is instrumental in the company’s overall winemaking operation by employing a multi-vineyard strategy and developing distinct flavors by blending wines from mutually complementary varietals.

Kirk graduated from the University of California at Davis with a Bachelor of Science degree in Viticulture and Enology.
