Ethanol boom may fuel shortage of tequila
Mexican farmers burning agave fields and replanting them with corn

MEXICO CITY – Mexican farmers are setting ablaze fields of blue agave, the cactus-like plant used to make the fiery spirit tequila, and resowing the land with corn as soaring U.S. ethanol demand pushes up prices.

The switch to corn will contribute to an expected scarcity of agave in coming years, with officials predicting that farmers will plant between 25 percent and 35 percent less agave this year to turn the land over to corn.
