GOLDEN TRIANGLE, Thailand—In the lush hills of northern Thailand, a herd of 20 elephants is helping to excrete some of the world's most expensive coffee.

Trumpeted as earthy in flavor and smooth on the palate, the exotic new brew is made from beans eaten by Thai elephants and plucked a day later from their dung.

Stomach turning or oddly alluring, this is not just one of the world's most unusual specialty coffees. At $1,100 per kilogram ($500 per pound), it's also among the world's priciest.

The Associated Press traveled to the coffee's production site in the Golden Triangle, an area historically known for producing drugs more potent than coffee, to see the jumbo baristas at work. And to sip the finished product from a dainty demi-tasse.
