Charles Shaw is the ‘overstock’ from some very fine wineries. (The better wineries will only bottle a finite amount of wine, law of supply and demand, in order to keep higher pricing. The wineries will sell off the excess.)
Charles Shaw wines come from
one winery: Bronco Wine Company in Ceres, CA They specializes in low cost product. The CEO of Bronco is related to Ernest Gallo.

The real reasons Trader Joe's wine is so cheap
Agreed. The majority of wine sold at local TJ's is utter swill. It's leftover product from grapes cooked in high heat, reducing actual acid in the grapes so you get thin, jammy flavors which are tossed together with zero thought to actual winemaking craft. Anyone who resorts to tossing oak chips into steel vats to "improve" flavor is only interested in pawning high-yield/low quality crap on unsuspecting wannabe wine enthusiasts who have yet to develop actual palates. Though this bogus trick is practiced regularly now, it started with the likes of Two-Buck Chuck in CA. If you want quality wine produced by winemakers who actually care about craft, look to Spain, southern Rhone Valley/France, and Italy, for starters. These are wines produced from small-yield vineyards, and you can still get good prices on the vast majority of it. CA can produce decent wines, but you'd think from the prices that they were imported from halfway around the world. It's nonsense and they've turned it into little more than a quantity-over-quality racket out there.
