Truffles have long captivated the culinary world, both for their rarity and the mystical allure surrounding them. From ancient mythologies to modern-day status symbols, the truffle's journey through history reveals not just a rare ingredient but a cultural icon that symbolizes prestige, rarity, and the epitome of luxury. With demand that often grows as prices rise—making it a quintessential Veblen good—truffles are as much about the experience as they are about the flavor. For centuries, truffle hunts have been carried out with a symbiotic partnership between humans and animals, initially with pigs and more recently, with trained dogs. Their elusive nature and complex, ephemeral aroma make them one of the most prized ingredients in the culinary world, calling for skill and precision to truly master. Whether purchased from a farm, at a bustling farmer’s market, or through the digital marketplace, the journey from soil to plate is steeped in tradition, local terroir, and often, the quiet hum of romance—both in the hunt and in the meal itself.
For this post, however, I’d like to offer a gentle warning. As I mentioned in my first blog of the season, Mapping Truffle Provenance and the Truffle Experience, diving deeper into the science of truffle may be a little like dissecting a frog — you might learn how it works, but in doing so, you risk killing some of the magic. The mystique, the romance, even the allure may fade slightly. But I believe that only by deeply exploring truffles and the associated human science that we can truly appreciate the full glory of this extraordinarily complex ingredient.
What I’m about to do — and what you’re about to read — reminds me of some of the most joyful moments of my childhood. I remember the delight of receiving a toy at Christmas or on my birthday. Being from an immigrant family, I didn’t get many, but when I did they were always thoughtfully chosen to ignite my imagination. The problem was (at least from my parents’ point of view), that after a short period of play, I couldn’t help myself — I’d dismantle the toy to figure out how it worked.
Under my bed, I kept boxes full of salvaged bits: flywheels, motors, wires, tiny globes. These parts would resurface later for repair attempts or to build entirely new imagined contraptions. To me, this didn’t take away from the joy of a new toy — it deepened it. Knowing how something worked only added to the wonder.
And so, I suppose, I’m doing the same now — only this time with truffles, something that has, over the years, come to captivate me just as deeply.
So here goes, are you ready? Hold on to your hat for this one.
Mapping Truffle Provenance and the Truffle Experience
Let me begin with a vision: that one day, truffles will be spoken about with the same sensory nuance and reverence as fine wine or specialty coffee. Imagine a restaurant guest writing something similar following a truffle meal:
“Last night I shared a bottle of Domaine LeRoy Chambertin Grand Cru 1990, and the epiphany perpetuated itself. The problem is how to explain this experience.
It may seem easy—just describe it—but we’ve all had moments, meals, and sensations where words fall short. Last night was one of those.
The fruit was still present, in balance, subtle—ethereal. Meat, blood, smoke, black fruit, mushrooms, truffles—all working in harmony. You knew there was more, but the wine was so complex, yet so simple, you couldn’t quite grasp it. It was sophisticated, smooth, and finished with the longest, most persistent finish I’ve ever experienced.
The wine paired with seared foie gras, lobster salad, duck breast, and Grand Marnier soufflé. I’m just so grateful for the experience.”
That level of depth, emotion, and sensory engagement is what I hope we can one day apply to truffles. The trouble is, we haven’t yet developed the vocabulary. Sure, we have a truffle aroma wheel—a sort of lexicon for identifying and describing the aroma—but we still don’t have a rich language for the truffle-on-the-plate experiences.
What do people usually say after a truffle meal? “Truffly!” “Earthy.” “Mushroomy.” Useful, maybe. But vague. Unsatisfying. They barely scratch the surface.
There’s another complication I’ve written about before: artificial truffle flavourings. For many, their first—and sometimes only—encounter with truffle is a bag of truffle-flavoured chips or oil laced with 2,4-dithiapentane. That chemical compound has become, for some consumers, the entire definition of what truffle is supposed to taste like.
The Truffle Experience Map
Truffles are among the most complex ingredients a chef can work with—not only because of their chemistry, but because of the wide array of factors that shape their character. Below, I’ve shared a revised mind map that attempts to trace some of those factors. In this post, I’ll expand on a few of the more significant contributors to that complexity, while noting that I’ve explored others—like pairing and our tree experiment—in earlier posts.
And then there’s the “everything else” category: the intangible aspects of truffle culture and ritual that shouldn’t be underestimated. After reading Charles Spence’s Gastrophysics, I’ve come to better appreciate those moments of theater in fine dining. Like the way a server emerges from the kitchen, white truffle in hand, moving with deliberate care toward my table.
It’s not just the $7,000-per-kilo tuber. It’s the walk, the pause, the way he checks that I’m ready before he dons white gloves and begins to shave it gently over hand-made pasta. It’s reverence. It’s anticipation. It’s multisensory. That, too, is part of the truffle experience.

Which Truffle Strain Are You Eating?
Did you know that Australia is home to one of the most diverse collections of Tuber melanosporum strains in the world? What’s more, many of these strains have remained largely isolated from each other since their introduction—meaning they’ve evolved on separate paths, subtly shaping their aroma, texture, and flavour profiles.
Why does this matter? Because research increasingly shows that strain matters. Just as grape variety shapes a wine, truffle strain plays a defining role in how a truffle smells and tastes. With enough knowledge (and a well-trained nose), you might even begin to identify which strain you’re eating—based purely on its aromatic fingerprint.
As shown in our Truffle Experience Map, there are at least four major strains worth mentioning:
The Garvey–Terry–Cooper Strain
This was the original strain introduced to Australia in 1999 by Duncan Garvey, Tim Terry and Peter Cooper. It’s the founding strain of the Australian truffle industry—and the one we grow here at Fish River Truffle.
The Terry Family Strain
After parting ways with Duncan and Peter, Tim and his family continued developing their own variant over the years, adapting and refining it on their Tasmanian farms.
The Truficulture Strain (Colin Carter)
Introduced later by Colin Carter and his team at Truficulture in Victoria, this strain brings a markedly different character. We have some of Colin’s inoculated trees on our farm, and the truffles they produce—especially those under French Oak—are very distinct from the rest of our harvest.
The Western Australian Strains
Finally, there are several strains cultivated in WA. These have evolved in a vastly different climate and soil context and offer a sensory profile unique to that region.
One of the joys of Australian-grown black winter truffle is precisely this: a chance to explore and compare the diversity of flavour across strains, farms, and growing conditions. We don’t yet have a widely accepted flavour map for Australian black winter truffle but hands up those who think we should?
What State Are Your Truffles From?
Just as strain matters, so does geography. I personally favour truffles grown here in New South Wales (NSW). They tend to be slightly softer in aroma than others, yet often more complex—at least to my nose.
Why? It comes down to climate and soil. NSW offers a climate that’s milder than Tasmania’s but colder and more defined than Western Australia’s. These conditions, combined with the geological diversity of NSW, produce truffles with subtle but compelling differences in character.
Yes, state-to-state variations are real—and the science supports it. We discussed Gary Lee’s work in a previous post, where gas chromatography revealed measurable chemical differences between truffles grown in different States. Have you started to notice the differences yet?
What Tree Was That Truffle Grown Under?
If you’ve followed us for any length of time, you’ll know about our truffle tree experiments—an ongoing exploration of how the tree species hosting the truffle affects its aroma and flavours. For years we relied on anecdotal observation, but now there’s peer-reviewed science to support what farmers and foragers all over Europe and now here in Australia have long suspected: host tree species affects truffle aroma.
Here’s how I’d describe it from the nose of someone who's been up close to thousands of truffles:
Hazelnut trees produce truffles with extraordinary diversity, complexity, and intensity. These are my personal favorite—rich, layered, and often with depth that lingers on the palate.
English Oaks offer something similar in tone to hazelnut-grown truffles, but with a tendency to be edgier.
French Oaks, by contrast, yield bold, spiky, assertive truffles. These can be intensely aromatic—sometimes overwhelmingly so. They demand care in the kitchen and are best paired with dishes that can hold their own.
The deeper we explore provenance—from strain to state to tree—the more we begin to appreciate the astonishing variability and potential within this ingredient. There’s no such thing as a “generic truffle.” Like coffee, wine, or olive oil, each one carries a story of its place, its genetics, and the hands (and paws) that found it.
Research with a Focus on the Consumer Experience
Truffles, the underground fungi we cherish, are a highly complex species. While modern farmers and researchers in Europe and, more recently, Australia have made significant strides in understanding how to grow truffles commercially—addressing questions like soil requirements, inoculation methods, and flavor replication for mass production—there’s one area that remains largely unexplored: the consumer experience and how to elevate it.
Most of what we know about truffles comes from centuries of European tradition, steeped in deep-rooted practices and sophisticated marketing. For those fortunate enough to live in Europe, this tradition is second nature. But what about cultures outside Europe? How do we experience truffles and how can we improve on what lives in the European context?
In Australia, where the truffle industry is rapidly growing, there’s a new landscape of questions that haven’t yet been fully explored. These questions go beyond production, delving into the culture and rituals of truffle consumption—an area that could easily be the subject of another post.
As we explore truffle provenance—from strain and region to the host tree—we begin to appreciate the incredible variability of this ingredient. Whether in Europe or Australia, one thing is clear: there’s no such thing as a “generic truffle.” Like coffee, wine, or olive oil, each truffle tells a unique story—its origin, genetics, and the hands (and paws) that unearthed it.
Well that's it for now. I hope you enjoyed it, if you did consider sharing it with a friend. If you have a question or a comment we would love to hear from you. Until next week when we will be taking another look at that old chest nuts aroma and flavour. Did you know the most searched for question on the internet regarding truffle is 'what do they taste like?
Until then
Cheers for now, Carmine
