Nestled between the cool confluence of the Stanislaus and San Joaquin rivers south of Lodi, the River Junction Appellation comprises 1,300 acres, the third smallest in California. The river basin, consistently 2-5 degrees cooler than the surrounding farmlands, combined with the sandy loam soils unique to the area, is ideally suited to growing premium quality grapes. McManis Family Vineyards grows Chardonnay, Pinot Grigio, Pinot Noir, Viognier, and Muscat Canelli in the AVA.
Established as an American Viticultural Area in 1985, Clarksburg is marked by its location along the Sacramento-San Joaquin River Delta, which pulls in ocean breezes and creates a cool maritime climate. The growing region has dense clay and loam soils. The McManis family grows about 220 acres of wine grapes with Chardonnay, Chenin Blanc and Sauvignon Blanc planted across their Northridge and Ridgecrest vineyards.
Located west of the Amador County line, Borden Ranch AVA is the most topographically diverse sub-appellation in the larger Lodi AVA. With elevations ranging from 73 feet to 520 feet above sea level, the region features well-drained alluvial soils comprised of cobbles, clay pan, and clay loam, best for growing structured red wines. McManis’ Liberty Vineyard and Sierra Loma Vineyard reside in the Borden Ranch sub-AVA. They grow Cabernet Sauvignon, Merlot, Petite Sirah, Petit Verdot, and some Pinot Noir in these vineyards.
Located in the east part of the larger Lodi AVA, Clements Hill is characterized by rolling hills and cliffs at the base of the Sierra Foothills. The Mokelumne River flows through the region and a variety of microclimates exist within the hills. There are granite and volcanic soils below the alluvial top soils, and the appellation is recognized for producing red grape varieties such as Zinfandel, Syrah, and Petite Sirah. McManis’ Lone Oak Vineyard sits within the Clements Hills sub-AVA, where they grow Cabernet Sauvignon, Zinfandel, and Petite Sirah.
Jahant is the smallest of the Lodi appellations and is most aptly defined by its unique pink Rocklin-Jahant loam soils, so much so that the boundaries of the appellation are marked by the extent of these soils. Jahant's climate is cool and dry due to its close proximity to the Mokelumne River, Sacramento Delta, and its relatively low elevations, ranging from 10 feet to 100 feet. McManis Family Vineyards produces Pinot Noir and Petite Sirah in the Jahant Appellation at their Creekside Vineyard.
The Mokelumne River is an American Viticultural Area located in San Joaquin County, California. It is located in the southwest part of the larger Lodi AVA, and includes the city of Lodi and the towns of Woodbridge and Acampo. The AVA is named after the Mokelumne River, which drains out of the Sierra Nevada Mountains, into the San Joaquin River and passes through the heart of the appellation. The wine region includes a portion of the lower Mokelumne River and the Cosumnes River, a tributary. The soil in the area is alluvial fan deposits of sand and loam. Ample rainfall and soil moisture retention allows most grape growers to farm without the use of irrigation. McManis’ Wishek Vineyard and Aberle Vineyard sit within the Mokelumne River sub-AVA; the family grows Cabernet Sauvignon, Tannat, and Teroldego here.
