Imitators beware. In light of the legions of Kona-coffee wannabes peddling false promises, a group of genuine Kona coffee growers recently banded together to sue several big-box stores, such as Walmart and Costco, for their role in a massive coffee fraud scheme. The crime? Passing off mediocre beans as Kona coffee. Grown only on the volcanic soils of Hawaiʻi’s Big Island (also named Hawaiʻi), Kona coffee is lauded by connoisseurs for its deep, “winey, spicy” flavor, and lack of a bitter aftertaste.
