At the jungle retreat that is home to the herd, conservationists were initially skeptical about the idea. "My initial thought was about caffeine - won't the elephants get wired on it or addicted to coffee?" said John Roberts, director of elephants at the Golden Triangle Asian Elephant Foundation, a refuge for rescued elephants. It now earns 8 percent of the coffee's total sales, which go toward the herd's health care. "As far as we can tell there is definitely no harm to the elephants." Before presenting his proposal to the foundation, Dinkin said he worked with a Canadian-based veterinarian that ran blood tests on zoo elephants showing they don't absorb any caffeine from eating raw coffee cherries.Picture: Paula Bronstein/Getty Images
