If you want to drink one of the best wines in the world, it's going to cost you — $6.

A Chilean wine sold exclusively at British supermarket chain, Asda, a subsidiary of Wal-Mart, was awarded a platinum "best in show" medal from the Decanter World Wine Awards, according to The Independent.

La Moneda Reserva Malbec, a dry red wine, won the prize for the best red single-varietal under £15 [about $20]. It was selected from 16,000 entries by a panel of 240 experts at the wine competition.

"At just £5.75 [$8], the exclusive La Moneda Reserva Malbec is the perfect example of how we're able to offer shoppers exceptional quality at low prices," Ed Betts, wine buying manager at Asda, told The Independent. "The La Moneda Reserva Malbec is also currently on rollback at £4.37 [$6], and as the perfect match to barbecued meats, we're expecting high demand in the coming weeks."

Sales of the wine skyrocketed following the wine competition, crashing the Asda website, the DWWA reported on Wednesday.
