White Truffle Smell 101 at the Alba White Truffle Fair

Meat chip

Ah, the Alba White Truffle smell! Back when I first moved I did a post on the 83rd Annual Alba International White Truffle Fair. In writing the post I realized that I haven’t a clue how to describe the white truffle smell. Luckily every Saturday and Sunday during the month-long fair there is a Truffle Sensory Workshop to teach such things. Perfetto. Field trip time.

The Truffle Sensory Analysis Workshop

Presented by the International Truffle Tasters Association (OIAT) Schedule: Saturdays & Sundays  Reservations Required: info@tuber.it or +39 0173 22 81 90

The hourlong session started with an intro to the tuber as well as a look at the white truffle smell. It was led by one of organization’s experts. He told us during the season he sniffs and tastes 1,500 truffles every Saturday and Sunday. Can you imagine? The course objective was for the student to recognize a good truffle from a bad one. Easy enough (ha).

Truffle Evaluation: Sight, Touch, and Smell. 

  • Touch: Touch gently. A good truffle will be not too hard, not too soft. Yes, yes – just right.
  • Sight: Clean, pleasant to the eyes, and sphere-shaped.
  • Smell: We were provided with a list of truffle scents – they should pretty much all scale about in the middle. Scents to look for include: mushroom, honey, hay, garlic, spices, wet ground, and ammonia.

Who says money doesn’t grow on trees?

Tree roots link to the truffle, but not all trees produce this magical fungus. Host trees: Common Oak, Turkey Oak, Durmast Oak, Pubescent Oak, White Poplar, Willow, Linden, Hop Hornbeam, Hazelnut.

Soil’s producing truffles are damp, chalky clay that lack organic substances like nitrogen and phosphorus, but are potassium rich.

Cool, damp environments create the truffle at 10 to 15 cm underground with an average temp is 6º C / 43º F. There was a whole scientific explanation on what happens with all this, but I glaze over with words like “mycorrhyza” and “mycelium”. So, read more here for those deets. The white truffle demands these prime conditions, or NO TRUFFLE FOR YOU! All of the above have to be just right.

True Story: Truffle Dogs are trained in Alba at Università dei Cani da Tartufo. Yep, the Truffle Dog University

Some places use pig for their catch, but not in Alba; they are just too hard to train. The beloved truffle dog feels the smell from the ground. Soil temperatures release a scent that only dogs pick up.

What’s that smell?

The interactive portion of the show included an opportunity to play with five truffles. Armed with our very own official evaluation sheet we were to touch and sniff (pretty sure scratching would have gotten me kicked out of Italy, but don’t think I didn’t consider it), and select the best truffle of the bunch.

Having the score sheet there to guide the eval was pretty cool. I never thought about scents of hay, honey, or wet ground as a white truffle smell. We were instructed to sniff quickly and in short intervals to not “stress the nose.”

The smells were pungent, some just plain icky, and lots of garlic. Odors on a dud are ammonia, methane, and fermentation. We measured each tartufo on a scale of 1 to 9, then we made our bold assertions about the best and worst.

Not a one of us picked the “right” white truffle, but we all did manage to identify the black truffle and the correct one was in everyone’s top two.

White Truffle Preservation: That Ain’t Happenin‘ 

Early in the season (September and October) eat your white truffle within 4 or 5 days. The best truffles are found in November in cold, icier conditions. These can be enjoyed for up to 15 days. 

Hands up – truffle police!

Experts from the OIAT are on hand at the Alba White Truffle Fair. Make a purchase, then take it over for evaluation. Now, this might seem a bit backwards – buy, then let the experts weigh in, but if you got a lemon the Truffle Police will accompany you back to the seller and explain the issues they have found, then get you a new truffle or a refund. Pretty cool.

Truffle Storage:

Store your white truffle between 3º and 6º C / 37.4º and 42.8º F wrapped in a damp cloth and tucked into a glass container. 

Let’s Eat!

It was a fun workshop that got us hungry. We stopped off at an osteria on the way home for fried eggs with white truffles. The server brought a white truffle, the shaving board, and a scale. They weighed the tuber, wrote down the number, then shaved till I said, “basta” (enough). After Il Ragazzo had his turn there was another weigh-in. We were charged by the gram.

October 2013 Market Price: 250 euros per 100 grams.

In 2012 white truffle prices were about 480 euros per 100 grams in early October, peaking at 530 euros the first week of November; weather conditions were better with a warm, arid, and dry summer. Right now white truffles are not as mature, but will get better as it gets colder.
