When I wrote about tequila, I learned the industry is dealing not only with non-Mexican varietals (would you drink one from Baltimore?), but also competition from China, where agave is now growing. As it turns out, the truffle industry is also in a fight with China, where less appealing types of truffles have infiltrated the market. As explained in a recent segment of 60 Minutes, 28 tons of Chinese truffles arrive in France each year. In many cases, these Asian truffles are sold at a lower price, but restaurants are then blending it into their truffle dishes at much higher prices. Or the fungi are being canned in France and marketed as French before exported to the United States.
