(SFGate) - Trader Joe's wine is remarkably cheap.

A bottle of the grocery store's most popular wine brand, Charles Shaw, sells for less than $3. 

Also known as "Two-Buck Chuck," Charles Shaw wine comes in multiple red and white varieties, including Cabernet Sauvignon, Chardonnay and Merlot.

The wine's low price has attracted some criticism. Critics have called it undrinkable and "sugar water." A wine shop owner once publicly accused the company that makes Charles Shaw wine, called Bronco Wine, of failing to remove dead birds, leaves, insects, and rodents from its grape harvests. Bronco Wine has denied the allegations. 

Despite the criticism, the wine is wildly popular. It's one of the best-selling products ever sold at Trader Joe's, exceeding 800 million bottles since the wine debuted at $1.99 in 2002, according to CNBC.
