The first AVA in San Luis Obispo County is established.
The Edna Valley AVA was established in 1982. It is located south of San Luis Obispo and extends to the ocean. Edna Valley has one of the longest growing seasons in California.


Two AVAs Established in North County.
AVA Status was awarded to approximately 614,000 acres surrounding Paso Robles. Gary Stemper, Mayor of Paso Robles, worked with local winemakers to establish the Paso Robles AVA. York Mountain AVA was also established on 6,400 acres in North County based the applications of Max and Stephen Goldman; it was located 12 miles west of Templeton, California. The York Mountain AVA is one of the smallest in the nation and contained only one winery, York Mountain Winery.


The Arciero Family opens Winery.
The Arciero has a family heritage of winemaking in southern Italy. Giovanni Arciero emigrated to the United States in 1914; his brothers Frank and Phil Arciero arrived in 1948 and moved to California. Their story is one of fulfilling the American dream. They started a cement contracting business, and as it prospered, they moved into land development in the Marina del Rey area of Southern California and were contractors in the building of LAX, Los Angeles International Airport. Their hobbies first centered on Ferraris and then wine. They started racing Ferraris in the late 1950s; their racing team included drivers Mario Andretti, Dan Gurney, and Al Unser. They began pursuing the wine business in the 1980s by studying grape growing areas on the Central Coast. They purchased 160 acres in 1982 and opened a winery in 1985 at 5625 Highway 46 East. They later purchased 500 acres near Shandon and planted additional vineyards with Nebbiolo and Sangiovese among other varietals. The winery was renamed EOS, after the Greek Goddess of the Dawn in the 1990s when new partners joined the Arciero family.


Large Corporate wineries plant vineyards in San Louis Obispo County.
Grapes grown in SLO County had been sold outside the country for almost 100 years. In the 1980s large corporate wineries began to realize that the quality of the grapes and the undervalued land were a perfect combination for investment.

Meridian Winery, home of the former Estrella River Winery, was established in 1988 on Highway 46 East in Paso Robles. Chuck Ortman, one of the veteran winemakers of Paso Robles, founded the label in 1984. Chuck started in the wine business in 1968, working in Sonoma and Napa Counties as a winemaker. He was able to move his operations to San Luis Obispo County with financial backing from Wine World Estates. Meridian was later purchased by a multi-national firm, Treasury Wine Estates. In 2016 Treasury Wine Estates consolidated winemaking operations on the North and Central Coast. The Paos Cellar 360 winery facility at 7000 Highway 46 East started producing the company’s “masstige wines” which sell in the $10 to $20 range to mass markets. The labels included BV Coast, Chateau St. Jean’s California line, Sterling Vintners Collection, Beringer Founders Estate, Sledgehammer and Meridian Wines. Treasury Wine Estates purchased the major of giant Diageo’s wine business in October 2015 including Beaulieu Vineyard and Sterling Vineyards. The luxury wines, defined as those selling for more than $20 in 2016, will be produced at its Beringer Winery in Napa. Treasury owns Penfolds and is Australia’s largest wine company as of 2016.

Jerry Lohr expanded his vineyards and built his winery in Paso Robles in 1988. In the late 1960s, Jerry Lohr, who had been raised on a South Dakota farm, started to research California grape growing regions. He is acknowledged as one of a handful of early pioneers who studied the California soils and climates and determined that Monterey County and Paso Robles AVA had the potential to grow world-class grapes and produce superb wines. In the early 1970s, Jerry planted vineyards in Monterey’s Arroyo Seco District. Jerry felt the cool, windy climate and the rocky soils were ideal for growing Chardonnay. He planted 280 acres in 1972 and 1973 near Greenfield. He planted Chardonnay and Pinot Noir. In 1974, he unveiled his winery, J. Lohr, in San Jose. In North SLO County, Jerry recognized the potential for growing Bordeaux varietals, great Cabernet Sauvignon and other red varietals, in the little-known Paso Robles AVA. He looked for land with rich soils and the dramatic diurnal temperature ranges between warm day and cool nights. Jerry began to plant his vineyards there in 1986. J. Lohr’s production facility was established near the Paso Robles Airport in 1988. He has worked in the industry for 50 years and continues to work actively to promote the region and wine education. He launched the 2013 Signature Cabernet Sauvignon in 2017, a celebration of his 80th birthday. He recently received the Wine Enthusiast Magazine’s American Wine Legends’ Wine Star Award and the Wine Business Monthly Innovator of the Year Award, excelling in the use of solar power. Today in 2018 J. Lohr Vineyards and Wines include more than 1,400 acres of cool-climate estate vineyards in the Arroyo Seco and Santa Lucia Highlands of Monterey County with an emphasis on Chardonnay, Riesling, Valadiguie and Pinot Noir. J. Lohr farms over 2,700 acres of vineyards in Paso Robles with the Cabernet and red wines varietals. The winery also owns Carol’s vineyard, 30 acres, in Napa Valley. J. Lohr’s children, Steve, Cynthia, and Lawrence have joined Jerry in partnership at J. Lohr Wines.
