Italian white truffles sold for almost $190,000

STORY: Last year's offering at the annual auction, weighing in at 830 grams, was sold for 103,000 euros.

This year the prized tuber went to a Hong Kong businessman after an auction held simultaneously in Hong Kong, Singapore, Seoul, Vienna and Doha.

The Italian northwestern region of Piedmont is known as Italy's producer of these tubers that grow spontaneously in the earth in just a few regions of Italy and central Europe.

With their unique flavor and aroma, they are found two to eight inches below the ground near the roots of trees with which they live in symbiosis and as they evaporate they give off an odor which lasts for a limited period of time and can only be detected by the assistance of well-trained dogs and experienced hunters.

The historic International Alba White Truffle Fair attracts around 100,000 visitors each year from all over the world who come to the little town in Piedmont to buy, sell and smell the expensive delicacy that, unlike black truffles which can be cultivated on plantations, grows only naturally in forests.
