Plant an Oak. Harvest a Truffle

  1. 1. in the garden Plant an Oak, Harvest a Truffle Cristina Santiestevan It used to be that you needed to train a pig and tramp through an oak forest in the middle of the French winter in order to hold a fresh black Perigord truffle in your hand. Now you can grow them in your backyard. Ancient poets and scholars once believed truffles were the fruit of lightning bolts hurled at oak trees by Jupiter, king of the gods. Today we know these warty, knobby, fist-shaped tubers are the fruiting bodies of a particular type of fungus, just like all j. r. accettola · www.accettola.com mushrooms. Thanks to the pioneering work of truffle farmers like Virginia Truffle Growers, these earthy delights are the next identical to the gastronomically adored Perigord region of French import to Virginia’s Piedmont—right after wine. south-central France. Famous for its wine, foie-gras, and native black truffle, France’s Perigord region has long supplied some From France’s Perigord to Virginia’s Piedmont of the most coveted ingredients for food lovers around the With hot, dry summers and mild winters, combined with roll- world. Already dozens of dedicated winemakers have proven ing hills of limestone-rich soil, the Piedmont’s climate is nearly our region’s ability to nurture fine wine-producing grapes among local hills and valleys. Will the famous black Perigord truffle be next? Truffle farmers in Rixeyville think it will. “This whole area is . . . very much like the [Perigord region] of France, where black truffles grow naturally,” explains Pat Martin. She runs Virginia Truffle Growers with her husband John, Tim Terry, a successful Tasmanian truffle farmer, and Maggie Shumack, who works directly with customers to estab- lish their own truffle-producing orchards. While they eventually expect to have about 3 acres planted with truffle-producing oak trees, the Virginia Truffle Grow- ers are actually more interested in growing truffle farms than truffles. Their Culpeper County farm is home to a commercial greenhouse and a sterile lab, where they inoculate oak seed- jules coon lings with the fungus that produces black Perigord truffles. An independent mycologist confirms that each seedling is properly inoculated before it is offered for sale. Oak saplings dot a hillside on the farm at Virginia Truffle Growers, which the owners have dubbed Le Clos de la Rabasse, or the Cul-de-sac of the Truffle. 19 www.flavormags.com
  2. 2. Pat Martin believes truffle growing is a great option for farmers or vintners who are looking to diversify their crops or to transi- tion to “something that doesn’t require 24-7 labor and intensive attention.” Local soybean and corn farmers are already begin- ning to inquire about the truffles, and the Virginia Department of Agriculture is interested in their potential as an alternative or specialty crop. Martin suspects our local vineyards may be especially well suited for truffle production. “We have every reason to believe the trees and the truffles are good companion products to the grapes,” explains Martin. “They certainly grow in very much the same kind of soil.” Enthusiastic home gardeners are also encouraged to join the truffle-growing adventure. In fact, anyone with space for a few oak trees—and patience to wait the four or five years until har- vest—could be a future truffle grower. “We’ve been contacted by people who want one or two trees,” says Martin, “and by j. r. accettola · www.accettola.com others who want to plant many acres.” It Takes an Oak to Grow a Truffle Truffle-producing fungi form an intimate relationship with tree roots—creating a radiating fan of delicate fibers—known as Truffle-Growing 101 mycorrizae, that look and act like root hairs. The edible truffles are the fruits of this mycorrizal relationship. The black Perigord truffle (Tuber melanosporum) grows best on the roots of oaks, and Virginia Truffle Growers currently offers holly oaks and English oaks. Both varieties have been producing ample crops of truffles for partner Tim Terry on his Tasmanian truffle farm. In some ways, truffles are no different than any other orchard crop. The trees are planted and carefully tended, and then the harvest begins around the fifth year. But there the similarity Virginia Truffle Growers sells truffle-bearing oak trees ends.

Bees, Nucs, & Queens Three Weeks of Culinary Euphoria As should be expected with anything so evocative, the season for truffles is fleeting. “The fresher they are when you use them, the better,” insists Martin, who warns that truffles lose their potent flavor about 2 weeks after harvest. Martin suggests “truffle virgins” seek out a quality restaurant for their first experience of this strongly flavored delicacy. More adventurous home cooks can try pairing shaved truffles with simple foods, such as scrambled eggs or mashed potatoes. Despite its recent domesticity, the truffle maintains the allure and mystery that has held food lovers captive since the days of Pliny the Elder. “It’s hard to describe the taste because it’s not like anything else I’ve ever eaten—it is so pungent, so won- [p] 540.937.7775 derful,” says Martin.
