There are certain things visitors arrive in Tuscany already knowing they are supposed to try.
Bistecca alla Fiorentina.
Pecorino.
Cantucci.
And, of course...
Vin Santo.
Usually the ritual goes something like this.
Dinner is finished. The waiter arrives with a plate of hard almond biscuits and a little glass of amber-coloured wine.
"Vin Santo!"
You dip the cantuccio into the glass, take a bite, and congratulate yourself on having completed another essential Tuscan experience.
Except...
What exactly did you just drink?
Because the words Vin Santo can lead you into one of the most fascinating and confusing corners of Tuscan wine.
At one end of the spectrum are extraordinary wines made from carefully selected grapes, dried for months, slowly fermented and aged for years in tiny wooden barrels called caratelli.
They can be incredibly concentrated, complex and long-lived.
And expensive.
At the other end are inexpensive sweet, fortified wines, vini liquorosi, sold in large bottles, poured generously into glasses and very often presented to visitors simply as "Vin Santo."
But it isn't! They are not the same thing, as the latter is not real Vin Santo and hence, if you look carefully, is not labelled as such. This is the fast-food version, and it is cheap!
Did someone try to fool you?! Probably not on purpose.
Even many locals have a very hazy idea of what real Vin Santo is.
So let's go down another Tuscan wine rabbit hole.
Because real Vin Santo is one of the most peculiar wines we make.
And one of the most misunderstood.
First Things First: What Is Vin Santo?
Vin Santo is traditionally a wine made from semi-dried grapes.
In Tuscany, the classic white grapes are varieties such as Trebbiano Toscano and Malvasia Bianca, although the exact permitted varieties depend on the denomination.
There are several protected Vin Santo denominations and styles across Tuscany, including Vin Santo del Chianti, Vin Santo del Chianti Classico, Vin Santo di Montepulciano, and others.
So there isn't one single recipe called "Vin Santo."
The regulations change according to where it is made.
But the traditional idea is remarkably consistent.
Instead of crushing the grapes immediately after harvest, as we would for an ordinary wine, the best bunches are selected and set aside to dry.
And then...
we wait.
Step One: Dry the Grapes
This is called appassimento.
Traditionally, bunches were laid on mats or racks or hung from hooks in well-ventilated rooms, often in the upper part of the farmhouse.
Walk into one of these rooms after harvest and it's quite magical.
Rows and rows of grapes.
Slowly shrivelling.
As the grapes dry, they lose water.
That means everything left inside becomes increasingly concentrated.
Sugar.
Acidity.
Flavour.
Extract.
And, importantly, the amount of juice available to the winemaker becomes less and less.
This is the first clue as to why serious Vin Santo costs so much.
Volume is sacrificed for concentration and flavor.
The various DOC rules can be surprisingly strict.
For example, Vin Santo di Montepulciano requires the grapes to be dried until prescribed sugar levels are reached, and they cannot even be pressed before certain dates: December for the basic wine and January for Riserva and Occhio di Pernice.
By then, those juicy grapes you harvested months earlier look very different indeed.
Then We Finally Press Them
Pressing dried grapes isn't quite like pressing freshly harvested grapes.
There isn't much juice.
What comes out is thick, rich and extremely concentrated.
And now we arrive at one of my favourite parts of the Vin Santo story.
The caratello.
The Tiny Barrel That Changes Everything
Traditional Vin Santo is aged in small wooden barrels known as caratelli.
They're much smaller than the large botti you see in Tuscan red-wine cellars.
Depending on the producer and denomination, they might be made from oak, chestnut or other woods, and old Tuscan wineries sometimes have caratelli that have been in use for generations.
The concentrated grape must goes into these barrels.
And then something very peculiar happens.
It is left there.
For years.
Vin Santo del Chianti Classico, for example, cannot be released until at least the third year following the harvest, and its production rules restrict the ageing vessels to small wooden barrels of no more than three hectolitres.
Elsewhere the requirements can be even longer.
Vin Santo di Montepulciano requires at least three years in wood for the standard wine, five years for Riserva, and an extraordinary six years for Occhio di Pernice.
And some producers go far beyond the legal minimums.
And Then There's the Madre
Ask an old Tuscan producer about the madre of their Vin Santo and things can become wonderfully mysterious.
The word literally means "mother."
Traditionally, the madre is the sediment known as lees remaining in an old caratello from previous production, containing microorganisms associated with fermentation very much like sour-dough.
When new must is placed into the barrel, some producers preserve this old material as part of the next fermentation.
You'll sometimes hear romantic stories of a madre being passed down through generations.
Grandfather's Vin Santo.
Father's Vin Santo.
Now the son's or daughter's.
There's both microbiology and mythology wrapped up in that little barrel.
Modern winemakers may understand and control the process much more precisely than their grandparents did, but Vin Santo remains a wine in which the individual cellar can leave an enormous fingerprint.
The Vinsantaia
And here's where things get even more interesting.
Historically, Vin Santo caratelli were often kept in a vinsantaia, frequently in an attic or upper room rather than in the cool, temperature-controlled conditions we associate with modern wine cellars.
Think about what happens in a Tuscan attic.
Winter? Cold.
Summer? Very hot.
The wine experiences enormous seasonal temperature fluctuations.
Fermentation can slow almost to a halt when it becomes cold and awaken again when temperatures rise.
Meanwhile, wine gradually evaporates through the wood.
The barrel isn't treated the way we would treat a barrel of Chianti Classico.
Traditionally, it may not be continually topped up.
That means the wine has contact with oxygen.
And oxygen, which winemakers usually spend enormous amounts of energy trying to control, becomes part of the Vin Santo story.
Isn't Oxidation Bad?
Usually when we talk about an oxidised wine, we mean something has gone wrong.
With traditional Vin Santo, controlled oxidative development is part of the character.
Over years, the colour deepens.
Golden. Amber. Copper.
Sometimes almost mahogany.
And the flavours change too.
You may find:
dried apricot,
fig,
raisin,
orange peel,
honey,
caramel,
almond,
hazelnut,
walnut,
spice,
coffee,
tobacco,
and all sorts of wonderfully difficult-to-describe oxidative notes.
A great old Vin Santo can smell almost impossibly complex.
And then you taste it.
Which brings us to another misconception.
Vin Santo Doesn't Have to Be Extremely Sweet
When I say Vin Santo, most people immediately think:
dessert wine.
And yes, many Vin Santos are sweet.
Some are extremely sweet.
But Vin Santo is not defined simply by sweetness.
Historically, fermentation in those little barrels could be unpredictable. Sometimes the yeasts stopped working while plenty of sugar remained.
Sometimes they kept going.
The resulting wines could therefore range enormously in residual sugar and character.
A Vin Santo can be luscious and dessert-like.
But another can be much drier, nuttier and almost savoury.
That's one of the reasons I think Vin Santo becomes much more interesting when you stop thinking of it simply as "the sweet wine we dip biscuits into."
It is an entire wine style.
And Then There Is Occhio di Pernice
Now we're going even further down the rabbit hole.
Occhio di Pernice means "eye of the partridge."
Unlike the familiar golden Vin Santo made primarily from white grapes, Occhio di Pernice is made with red grapes—most importantly Sangiovese.
In Montepulciano, for example, Vin Santo di Montepulciano Occhio di Pernice must contain at least 50% Sangiovese, locally called Prugnolo Gentile.
The resulting wine can have gorgeous copper, amber, reddish and tawny colours, with extraordinary concentration.
And production can be minuscule.
Remember what we're doing.
We're taking perfectly good Sangiovese grapes.
We're drying them.
We're losing a huge amount of potential wine.
We're extracting a tiny quantity of concentrated must.
Then we're putting it into tiny barrels.
And waiting.
In Montepulciano, the maximum finished wine yield for Vin Santo is just 35% of the weight of the fresh grapes.
Suddenly that little 375 ml bottle with the rather frightening price tag begins to make more sense.
So Why Is Real Vin Santo So Expensive?
This is perhaps the easiest question to answer.
Because almost everything about making it is economically ridiculous.
You need good grapes.
You select them rather than putting them into your normal wine.
You dry them for months.
You lose water and therefore volume.
You press them and get very little juice.
You put that precious juice into small barrels.
You store those barrels for years.
Some of the wine evaporates.
Some barrels may develop badly.
And all that time, your money is sitting in a tiny wooden cask instead of being sold.
Then, years later, you finally bottle what remains.
A serious Vin Santo is almost the opposite of an industrially efficient wine.
Which is part of its beauty.
Now Let's Talk About the Other "Vin Santo"
Here's where I think consumers need to pay attention.
Go into a Tuscan supermarket or souvenir shop and you may find something that looks remarkably familiar.
Amber wine.
Traditional-looking label.
Perhaps a rustic bottle.
Maybe even the words Santo prominently displayed.
Turn the bottle around—or look carefully at the classification—and you may discover the words:
Vino Liquoroso.
And that changes the conversation.
What Is Vino Liquoroso?
A vino liquoroso is a fortified wine.
In simple terms, alcohol has been added during its production.
This is a completely legitimate category of wine.
There is nothing inherently wrong with fortified wine.
The problem isn't vino liquoroso.
The problem is assuming that a cheap Tuscan vino liquoroso and a traditionally produced DOC Vin Santo are the same product simply because both are amber, sweet and served with cantucci.
They aren't.
Traditional Vin Santo gets its potential alcohol and sweetness from the concentration of the grapes through drying and from what happens during fermentation and long ageing.
A liquoroso achieves its alcoholic structure through fortification.
The production process can therefore be much quicker, easier and less risky.
And the price usually reflects that.
Read the Label
This is one of those wonderfully simple pieces of wine advice.
Don't just look at the picture on the front.
Read the words.
If you see:
Vin Santo del Chianti DOC
Vin Santo del Chianti Classico DOC
Vin Santo di Montepulciano DOC
or another recognised Vin Santo denomination, you're looking at a wine that has been made according to the production regulations of that denomination.
If the bottle says:
Vino Liquoroso
then that's what you're buying.
A fortified wine.
It may be tasty.
You may enjoy it.
But don't confuse the two.
There are commercial products sold specifically as amber Tuscan dessert wines with vino liquoroso stated somewhere on the label, while genuine denominated Vin Santo follows very different production requirements.
And once you know what to look for, the distinction becomes much easier to spot.
But Is "Real" Vin Santo Always DOC?
Here's where I have to complicate my own argument.
Because Tuscany is Tuscany.
There are families who have been making their own vin santo for generations.
A few bunches hung upstairs.
An ancient caratello.
A mysterious madre nobody dares throw away.
A barrel opened after several years for Christmas, a wedding, a baptism or simply because somebody finally decides it's time.
That wine may not carry a DOC denomination at all.
And I certainly wouldn't call it fake.
In fact, it may be one of the most authentic expressions of the tradition you could possibly taste.
So when I talk about "real Vin Santo," I'm talking primarily about the method and the tradition.
The protected denominations give us something extremely useful: rules and guarantees about origin and production.
But Vin Santo existed in Tuscan farmhouses long before modern DOC regulations did.
That's worth remembering.
Why Is It Called "Holy Wine"?
Good question.
And, as so often happens with wine history, we don't have one beautifully tidy answer.
There are several stories.
One connects the wine to religious use and the wine used during Mass.
Another tells of a friar using wine during the plague.
Another famous story links the name to the Council of Florence in the fifteenth century, when a Greek churchman supposedly compared the wine with a wine from Xanthos, leading listeners to hear something resembling santo.
Are any of these definitively the answer?
Not really.
And perhaps that's appropriate.
A wine this strange deserves a slightly mysterious name.
And What About the Cantucci?
We can't talk about Vin Santo without talking about the biscuits.
Cantucci and Vin Santo.
It's one of Tuscany's most famous food-and-wine pairings.
And yes, dipping the hard almond biscuit into the wine softens it and creates a delicious combination.
But here's my little plea.
If somebody pours you a beautiful, complex, carefully aged Vin Santo...
taste the wine first.
Please.
Smell it.
Taste it on its own.
Let it tell you what it has spent the last five, ten or twenty years becoming.
Then eat the cantuccio.
Then, if you absolutely must...
dunk away.
But at least give the wine a fighting chance first.
What Should Good Vin Santo Taste Like?
Forget simply asking whether it's sweet.
Look for balance.
A great Vin Santo may have enormous concentration, but it shouldn't just taste like sugar.
It needs acidity.
That freshness is what stops the wine becoming heavy and tiring.
You want complexity.
Dried fruit.
Nuts.
Spice.
Caramelised notes.
Oxidative character.
Perhaps some volatile lift.
And a finish that seems to go on forever.
The best examples have that wonderful contradiction that great sweet wines often possess:
richness without heaviness.
You take one tiny sip... And you're still tasting it a minute later.
The Wine Tuscany Almost Forgot
For me, Vin Santo is fascinating because it represents an older idea of winemaking.
Not efficient. Not predictable.
It doesn't fit neatly into our modern desire to control temperature, oxygen, fermentation and every other variable.
It requires space. Time. Patience.
And a slightly irrational willingness to take beautiful grapes and turn them into a very small amount of wine many years later.
Perhaps that's why truly great Vin Santo isn't something every Tuscan producer makes anymore.
But when you taste a serious one, you understand why some continue.
It's not simply a sweet wine served at the end of dinner.
It's a little piece of Tuscan agricultural history.
So next time someone puts a tiny glass of amber wine in front of you, don't automatically reach for the cantuccio.
Look at the bottle.
Read the label.
Ask how it was made.
Ask how long the grapes were dried.
Ask about the caratelli.
Ask whether there's a madre.
And above all...
taste the wine.
Because if it's the real thing, somebody may have been waiting years for you to drink it.
The Perfect Contrast
Cantucci and Vin Santo may be Tuscany's most famous pairing, but some of the most exciting matches work precisely because of contrast.
The sweetness, concentration and acidity of a great Vin Santo can be wonderful with the saltiness of an aged Pecorino or blue cheese. It can cut through the richness of foie gras, while the savoury, slightly bitter flavours of a traditional Tuscan crostino di fegatini create a completely different kind of balance.
Sweet against salty. Rich against fresh. Savoury against luscious.
Sometimes the perfect pairing isn't about matching flavours at all.
It's about letting opposites make each other taste better.
If you have another favorite pairing, let me know - I'm curious.
