The Truffle Growers' Forum is an annual gathering and focal point for North America's truffle cultivation industry. It attracts an international cast of speakers, and growers from across the continent to discuss the breadth of thought and methods employed by successful truffle producers throughout the world. It enables growers, researchers, journalists, and truffle purveyors to keep up with advances in truffle science, engage with a wealth of experts, and make valuable contacts within the industry. The program for this event is dynamic, with different speakers each year, showcasing recent developments from around the globe. We assemble the best program possible, but as in any good conference, who you meet is often as valuable as what you learn. Since its inception in 2006, the Truffle Growers' Forum has served as a unique catalyst for future business and research collaboration.

The Truffle Growers’ Forum will be held Friday, January 24th, and Saturday, January 25th, 2014 at The Hilton Eugene, headquarters hotel for the Oregon Truffle Festival. Friday consists of a lecture series with this year’s speakers covering the breadth of the truffle cultivation industry. Breakfast and a truffle lunch are included on Friday.

Saturday’s events are in the field, touring a research truffiere designed to produce five European truffle species and three Oregon truffle species, as well as a truffle hunt with truffle dogs for the native Oregon white truffles. Breakfast and a festive winemaker’s luncheon with a guest chef are included on Saturday.


Dr. Christina Wedén, biologist and mycologist from Uppsala, Sweden, first started working with truffles in 1997. Prior to this, truffles were unknown to the general public in Sweden. Christina’s PhD thesis in 2004 dealt with the naturally occuring Burgundy truffle in Sweden and in this work the first truffle orchards were planted in Scandinavia. Parallel to research and teaching at Uppsala University, Christina runs the private company Tryffikultur AB together with agronomist Lina Pettersson. Since 2010 Christina is an elected member of The Academy of Culinary Arts and Meal Sciences, working interdisciplinary with science related to food and culture.
