Wherever there is a Trader Joe's there is 2 buck chuck (Charles Shaw)
The story behind Two/Three Buck Chuck was that there was a glut of grapes in the Central Valley in the late 1990s. Fred Franzia (nephew of Ernie Gallo) saw the opportunity to buy these grapes cheap and repackage them for the market. Instead of targeting the oversaturated (and declining) jug wine market, he figured he could sell cheap wine to yuppies. He got his Charles Shaw wines to be distributed in Trader Joes and the rest is history.
BTW: This is similar to what happened in the mid-80s, when the Central Valley had another glut of grapes. In that case, the Gallo family took the lead and developed the "Wine Cooler."
