Viader
family name
Viader Vineyards & Winery (oft spelled capitalized as VIADER) is a 96 acres (39 ha) winery located in Deer Park, California, United States at 1,400 feet of elevation. It was founded in 1986 by an Argentinian immigrant to the United States, Delia Viader, after receiving a loan from her father to start the business. The winery produces wine from mostly red grape varieties such as Cabernet sauvignon, Cabernet franc, Petit verdot, Malbec, and blends of some of these reds with one another. According to Wine Industry advisor, "96% percent of VIADER’s wines are not available to the general public", being sold instead mostly to visitors to the winery itself.
The Viader winery has been certified organic since its opening.
In 2006 Delia Viader's son, Alan Viader, became the lead winemaker running the vineyard and winery.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Viader”, the useful work is to connect “family name” to the records capable of establishing context and consequence.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Jan 19, 2026. The linked authority identifier is Q110820627. Authority coordinates are 38.561, -122.475. None of the 1 selected statements returned an explicit reference. The first chronological checks are 1986, 2006, 2020 and 2005.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
