How many times has it happened to you at the restaurant to smell a wine with a lost look in the vain desperate for a neuron capable of making such an unknown synapse? In this brief guide I teach you 3 easy tricks to understand if a wine tastes of cork.

When does a wine taste like a cork?

"Great is the luck of one who has a good bottle, a good book, a good friend." Molière

Before answering this question let's start from the ABC: do you know what cork smell is?

The corky smell is due to a substance, TCA (trichloroanisole), which is formed in the event that the cork is attacked by a fungus, the Armillaria mellea… Which is none other than the very common Chiodino mushroom (I'm sure you happened to eat it at least once in your life!). Yes, the very common boletus mushroom that you buy at the supermarket and sautéed with tagliatelle or eat sautéed on a bruschetta is the feared responsible for the cork disease that irreparably damages the wine!

 "But how Chiara... are you telling me that my beloved chiodini mushrooms that I also sbafato last night with a tray of pappardelle are those parasitic criminals who make me throw euros and euros of wine and make me look like mexxa at the restaurant with the woman or friends ? Are you kidding?"

No, I'm not kidding: the honey fungus actually contains a protein toxin that disappears only when cooked at a temperature above 65 ° C. For this reason, if it attacks the cork, it forms the TCA and gives that unbearable smell of wet dog, damp cellar or moldy newspaper ... Yes, the tender and bitter flesh of the nail mushroom cap is the main enemy of winemakers, sommeliers and consumers! This pest is devastating because it can lead to death in the trees on which it grows mainly in the rainy autumns of Europe and North America.

“And so Chiara if I want to sauté these delicious noodles safely by myself, how the hell do I do it? "

You probably happened to cook some nails without even knowing that when raw they were toxic! To be 99,99% safe, just boil the mushroom for 10-15 minutes in water, taking care to throw out the water before proceeding to the desired cooking.

But let's get back to us ... The cork stench in wine identifies a defect that can be easily recognized (if the diseased cork looks like this below)


Thanks to my friend Gianluca Morino, owner of Cascina Garitina for involuntarily lending me the photo 🙂

I immediately dispelled a myth: even wines inside screw-capped bottles can have a hint of cork! In fact, this defect is not necessarily inherited from the cork, but the dear honey fungus (it is na chioda in fact) also attacks the wood of the barrels (this fungus loves humidity, like many others) ... therefore potentially all wines that spend a period in wood they can taste like cork! So I absolutely DO NOT agree with Intravino when he writes:

“The cursed cork, the cross of every enophile with a serious cellar, is a ruthless killer. A microorganism present in the cork is responsible for the transfer of the homonymous smell to wines, without distinction of caste: it can randomly afflict cheap wine and leasing wine. We all hate it. This is why we have learned to love alternative closures (screw cap, metal crown, silicone): at least with those you are sure that you will save yourself. The sensation is exactly that of cork, which is felt in a clear and inevitable way, and among the enoevoluti is described with the term TCA (trichloranisole) to identify the molecule responsible for the nuisance. Obviously, defining a wine that tastes like a cork as “affected by TCA” is enormously cooler. "

Fiorenzo Sartore, vintner and founder of Intravino.com

I don't want Fiorenzo Sartore if for the second time I find myself in disagreement with him! As I already have ofchiarat I highly esteem his work, which is the second time in a month that it happens I find it a pure fatality!

"You are like wine: the older you get the more you taste like a cork." Luciana Littizzetto "

In short, not even the screw cap will save you from that annoying smell ... As the agronomist Lamberto Tosi writes on his blog AcquaBuona.it:

“The modern disquisition on the plastic cap fits into this problem, which as such should be immune from the“ cork ”defect, but which in reality, precisely because the cork is rarely the real origin of the problem, does not substantially solve the problem. Perhaps he adds others because if we are at an in-depth level in the possible problems related to the cork stopper, we are certainly at the beginning with regard to the sales and evolution of wines sealed by these stoppers. "

Lamberto Tosi, agronomist

"So how does this cap work?"

In summary, a wine is a cork if:

  1. Learn to trust the first impression: you will rarely be wrong!
  2. It smells of mold, of a wet dog, of a damp cellar, of wet clothes forgotten in the washing machine ... (I'm sure that you too have at least once forgotten your washed clothes still wet in the washing machine for days ...)
  3. When tasted it is bitter and smells of moldy.

And remember to never take it for granted that if you see a piece of cork floating in the wine there are hints of cork: any cork residues can be caused by an incorrect opening that has damaged the cork!

One last thing: throwing away food or wine, especially in this historical period, is never pleasant. Take advantage of the fact that TCA is volatile: with a wine that tastes like cork you can cook easily because the TCA evaporates during cooking! Then obviously the situation must be evaluated from case to case ... but in general it is better to braise a good Barolo with a slight hint of cork than a completely "healthy" Tavernello ...



"Nothing and nobody can make you feel inferior, unless you allow it."

E. Roosevelt.

That is ... if you are at a restaurant and you realize that they have brought you a bottle that tastes like a cork, don't be ashamed to ask for a new one: if you pay, you have the right to drink well and the restaurateur in question has the duty to make you drink well! Don't be afraid to DARE to trust your impression, especially in restaurants where there is NOT a sommelier and therefore probably have difficulty storing bottles correctly. Remember: there is a "fake cork smell" that can arise when the bottles are stored vertically and therefore there is no contact between the cork and the wine ...

See you soon and a hug,
