Family owned and operated since 1990 by Ron and Jamie McManis, McManis Family Vineyards now farms over 2,600 acres of premium wine grapes located throughout the Northern interior of California. Justin and Tanya McManis, the fifth generation of family farmers are very much involved in the day-to-day operations. The McManis family has been growing grapes in this region since 1938.

With four generations of farming experience, McManis Family Vineyards has been one of the leading wine and grape producers since 1990. McManis Family Vineyards is known for ultra premium grape growing featuring selected rootstocks and clones, leaf pulling, cluster thinning and drip irrigation. Along with an eye for detail in the vineyards, their commitment to sustainable practices has led them to pursue green certification.

That commitment to excellence has also been shared in the winery where after the 1997 harvest, a state-of-the-art winery was designed and built to maximize the resulting wine's quality. Attention to detail comes in the form of small lot fermentation, whole cluster pressing and oak aging - all designed to provide the winemaking team at McManis Family Vineyards the tools they need to produce the finest wines possible.

It is the sole objective of our family to produce the finest wine and winegrapes in the Northern Interior of California, as well as provide the best service possible. Our dedicated and long term staff utilizes grape growing and winemaking methods found in the ultra premium wineries throughout the world to deliver some of the fines grapes and wine produced in California. Every step in the production process, every business decision made by the family, is carefully considered to enhance the grapes and resulting wine produced for McManis Family Vineyards and its customers.
