In 1996, with forty years of winemaking experience, Jim and Mary Dierberg’s dream of producing wines worthy of their 250 year plan became a reality. After a long search through France and Napa, while learning the craft and making wine in the mid-west, they discovered the potential of Santa Barbara’s cool coastal valleys. The family planted two estates -first their namesake Dierberg Vineyard and later Drum Canyon Vineyard – both under their DIERBERG label. These estates, along with the family’s iconic warm climate site Star Lane Vineyard, culminated in a trio of peerless properties in Santa Barbara County.
Today, the entire operation is one big family affair, with the Dierbergs’ grown children and their spouses intimately involved in the day-to-day operations of the vineyard and winery.
Bankers by profession, Jim and Mary are no newcomers to wine. Since 1974, they’ve owned the Hermannhof Winery in Hermann, Missouri, which was one of the United States’ most significant wine-growing regions prior to Prohibition. Located about an hour’s drive west of St. Louis, Hermannhof is one of America’s oldest wineries. The Dierbergs have dedicated the past 40 years to renovating the property and raising its reputation as a place for education and entertainment.
While the town’s history and charm brought the Dierbergs to Hermann, the region’s Midwestern climate cannot support the traditional European varietals that Jim and Mary have become fans of over the years. In the 1980s, the Dierbergs began looking outside of Missouri for a place to plant that passion. After realizing that properties in Bordeaux and Napa Valley weren’t suitable for their desires, they chanced upon the Santa Barbara area in 1996.
Dieberg Vineyard:
Thirteen miles from the Pacific Ocean in one of the cooler winegrowing corners of Santa Barbara County, Dierberg Vineyard is on the western edge of the Santa Maria Valley appellation and is comprised of Pinot Noir and Chardonnay. Perched on a mesa above the south bank of the Santa Maria River, the property consists of sandy loam soils, heavily infiltrated by the marine sediments of yesteryear and kissed by the fog from the Pacific.
Founded in 1997, the family planted twelve “heritage clones” of Pinot Noir (tracing back to Burgundy). This diversity of material is rare in California, and allows the selection and discovery of the ideal clones to build the backbone of DIERBERG Pinot Noir. Chardonnay selections were derived from marquis cuttings of historic Wente clones — and the closely related Clone 4 grape. These California-developed clones are high quality and low yielding, producing expressive but graceful Chardonnays by retaining fresh structure with delicious ripe fruit.

Jonive Chardonnay Russian River Valley is made from 100 percent Chardonnay.
2021 Jonive Russian River Estate Chardonnay: Harvested the night of September 20th with the two clones kept separate. The clone 95 was pressed into tank where it was chilled, settled and racked, then allowed to ferment naturally for 12 days when it then went to barrel. The primary and secondary fermentations lasted in barrel until April 20th, some seven months. The wine remained on its original lees until just prior to bottling. The clone 17/Robert Young chardonnay was pressed into tank and allowed to brown naturally before a natural fermentation occurred. This lasted for 15 days before going to barrel where it finished the last 12 days of primary fermentation and six weeks of secondary fermentation and it too rested on its original lees until just prior to bottling.
The wine has a typical straw color and complex aromas of lemongrass, nutmeg, Meyer lemon and a touch of passionfruit. It has an enveloping mouthfeel that is at once tart and linear as well as rich and expansive, a very unusual and beguiling combination of textures and mouthfeel. The browning of the clone 17 enables the wine to be rich, but at a lower alcohol (13.3%) and the clone 95 contributes beautifully fresh acidity. The pallet shows jasmine, honeydew melon, tarragon and lemongrass with a nice kiss of high-quality French oak. The extended lees contact gives the wine amazing length, energy and vitality.

Reviews:
A wildly elegant aromatic profile announces this Chardonnay from Jonive's estate vineyards, a combination of two separately fermented clones, 95 and clone 17, also known as Robert Young. The blend is beautiful and effusively aromatic. Lemon cream and white flowers mark the aromatic profile, and the palate, crafted with plenty of lees contact, shows a creamy texture of lemon and orange oils. Savoury notes of sorrel and lemongrass mark the lengthy finish. The new French oak kisses this wine just a touch with a note of Madagascar vanilla on the finish.
-Decanter 94 Points
This seamless, smooth and mouthfilling wine is packed with ripe fruit flavors and deftly accented with oak notes like vanilla, hazelnut and toast. It's rich in texture yet relatively light in body, encouraging flavors that mingle with a subtlety that asks for more sipping.
-Wine Enthusiast 94 Points
A fresh, wild, and savory expression with vibrant acidity and an elegant structure. Earth-laced fruit aromas of blackberry bramble, dark cherry, and huckleberry seamlessly intertwine with savory hints of curry leaves and lobster mushrooms, accented by subtle notes of dried orange peel and baking spices. Earthy and floral elements—forest floor, conifer needles, and rose hips—carry through to the palate, beautifully integrated with effusive raspberry and cherry notes, leading to a long, spicy finish.
This impressive Pinot is polished and detailed, offering dynamic flavors of raspberry and blueberry, with mineral and brown baking spice hints that build richness toward fine-grained tannins.
