Three years after the harvest of Australia's first black truffle in Tasmania, the gourmet truffle industry is struggling as adverse weather conditions have affected truffle harvests.

Perigord Truffles of Tasmania, the founder of the Australian truffle industry and its biggest player, had been hoping to harvest between 20kg and 30kg of truffles this season but instead bagged just under 6kg. The previous season produced around 5kg.

Perigord co-chairman Duncan Garvey put the poor harvest down to the weather: "Tasmania had a very cool and wet summer, and then the mildest winter in 100 years. Normally one can balance out the other, but when you get one on top of the other, it makes it very hard."

The quality, however, has remained unaffected, according to Garvey. The 6kg harvest sold for A$3000 (US$1,689) per kilogram, reported The Australian.
