Charles Shaw is an American brand of "extreme value" wine produced in California.  I buy it by the case.  Their chardonnay is excellent - and recently won the Best in Glass award at a major CA wine festival.  It's crazy good and crazy inexpensive.  You can find it at many (but not all) Trader Joe's locations.  Call ahead to see.

Charles Shaw wines are currently Cabernet Sauvignon, Merlot, Chardonnay, Sauvignon Blanc, and most recently Shiraz varietals and Valdigue in the style of Beaujolais nouveau, all from California vineyards. They are distributed exclusively by Trader Joe's grocery stores, and in California sell for $1.99. Because of this, the Charles Shaw wines are affectionately known as Two Buck Chuck.    

Due to some sort of regulation, in some states (like MA) the price can go up to around $3. As such, the wine is often referred to as "Three Buck Chuck".

Charles Shaw is an example of the recent trend of economy-minded wine drinkers seeking the greatest value. In particular the brand stands out not only for the low cost, but also for the respectable packaging and semi-frequent high ratings at wine tasting events.  Try it and see!
