As holiday parties approach, so does the specter of sipping from a small plastic cup of inexpensive wine as you make small talk. Ever wonder where the names on those bottles came from? Here’s the background on a few familiar California brands. Feel free to use these stories to spice up boring holiday party chitchat.

1. Ernest & Julio Gallo

Ernest & Julio Gallo formally founded what’s now the world’s largest family-owned winery in 1933, but they had already tasted some success during Prohibition. While selling wine was illegal in those days, there was no law against selling grapes and everything else you needed to make wine at home. Thanks to this loophole, the Gallo family wine empire was turning a profit before the Gallos ever really started making wine.

After their parents’ death in a grisly murder-suicide, brothers Ernest and Julio began making and marketing their own wine. Julio spearheaded the wine production and proved to be a wizard at cranking out giant batches of wine that maintained a consistent flavor profile. Ernest, on the other hand, worked on the business side and showed a knack for talking retailers into carrying his brother’s wine.

The brothers weren’t always so nice to other family members, though. After they booted their youngest brother, Joseph, from the wine business, he tried to start a cheese business of his own using the Gallo name. Ernest and Julio successfully sued to block him from using “Gallo” on any of his cheeses. (They were jerks to other people, too; one infamous story about the Gallos involved them dropping cigarette butts into competitors’ bottles, resealing them, and placing them back on the shelves for unsuspecting buyers.)

Family bitterness aside, the Gallos were masterful in building brands. When Ernest died in 2007, reports pegged the company’s output at 900 million bottles of wine each year.

2. Carlo Rossi

Carlo Rossi, the patron saint of jug wine enthusiasts everywhere, hooked up with the Gallos in 1953 just as the brothers were starting to roll out some of their brands nationwide. (The fact that Rossi was a distant relative of the Gallos probably helped him nab the gig.) Although Rossi’s main job was helping Ernest Gallo break in new markets, the Gallos gave him a little perk in 1962 when they named their new line of jugged wines Carlo Rossi Red Mountain.

The Rossi brand was originally just a regional offering for the California and Nevada markets, but it proved to be so popular that the Gallos took it national in the early 1970s. The brand needed someone with a distinctive voice to narrate its radio ads, and Rossi’s endearingly awkward delivery earned him that job, too. Here’s an early spot of Rossi talking about his wine:

3. Charles Shaw

Charles Shaw’s name hasn’t always been synonymous with “Two Buck Chuck” thanks to the wine’s cheap price tag. Stanford-educated Shaw moved to Napa in 1974 with dreams of developing a Beaujolais that bore his name. Although Shaw’s Beaujolais was pretty tasty, his business plan never really found any traction. Shaw and his wife ended up selling their winery when they divorced in 1991.

Fred Franzia’s Bronco Wine Co. bought the Charles Shaw name and stowed it away in its portfolio of brands for a decade. When grocery chain Trader Joe’s asked Bronco to develop a low-cost house brand of wine for its stores, the company dusted off the old label for the cut-rate vino.

Poor Charles Shaw. He just wanted to make Beaujolais, and now his name is synonymous with cheap wine. However, he can take some heart in knowing that Two Buck Chuck has improbably won a few accolades. In 2007 the Charles Shaw 2005 California chardonnay won Best Chardonnay from California at the California State Fair Commercial Wine Competition.

4. Sutter Home

Sutter Home Winery often draws sneers from serious oenophiles thanks to its association with white zinfandel, but the winery has actually been around since 1874. Swiss immigrant John Thomann founded the winery, and in 1947 Italians John and Mario Trinchero bought it.

Wine aficionados may not know it, but the Trinchero brothers originally focused on making traditional zinfandels at Sutter Home. A bit of good luck in 1972 changed all that, though. Mario Trinchero’s son Bob was experimenting with ways to generate more intense flavors in the family’s zinfandel. He reasoned that he might have some luck by lowering the ratio of grape juice to grape skins in the recipe, so he drained 500 gallons of juice off of one batch.

Bob Trinchero didn’t want to waste 500 gallons of perfectly good grape juice, though, so he fermented it, put it in barrels, and figured he’d sell it in the winery’s tasting room as a novelty. When tasters began tossing back Trinchero’s invention faster than he could make it, he decided to bottle the product.

Trinchero originally called the sweet, pink wine Oeil de Perdrix (French for “eye of the partridge”), but ATF regulators told him he would need at least some English on his labels. He responded by dubbing his creation “a white zinfandel wine,” and the sweet elixir quickly became America’s most popular style of wine.

5. Robert Mondavi

Robert Mondavi found winemaking fame in an odd way: he got into a fistfight with his brother. Mondavi, the son of Italian immigrants, graduated from Stanford in 1937 and immediately went to work in the wine business. His family later bought the Charles Krug Winery, and Mondavi ran the business with younger brother Peter for 23 years. The brothers often clashed over Robert’s desire to make top-shelf wines, though, and things came to a head in 1965 when they got into a fistfight.

Brothers tussling is usually no big deal, but Robert Mondavi later wrote, “When it was all over, there were no apologies and no handshake.” Robert had effectively punched his way out of the family business, so he opened a winery bearing his own name. As you probably know, socking his brother turned out to be a brilliant business strategy for Mondavi. When he died in 2008 at the age of 94, he was mourned as a man who doggedly worked to increase the international profile of California wine and popularized the term “Fumé Blanc.”

Mondavi’s Washington Post obituary even included a happy note on his family feud. In 2005 Robert and Peter Mondavi put aside their differences to make wine together for the first time in four decades. Each brother contributed half of the grapes to a single barrel of a cabernet blend. Wine enthusiasts were more than a little excited about the collaboration; the barrel sold for $401,000 at auction.
