Before you start: glass, temperature, and not being distracted
Three things separate a tasting that teaches you something from one that leaves you confused. The first is the glass. It does not need to be enormous, but the bowl should narrow towards the rim so the aromas gather instead of escaping. A white wine tulip or a classic Bordeaux shape covers almost everything.
The second is temperature, and it is the most underrated part. A red served too warm smells of alcohol and little else. A white served too cold has no aroma at all. Roughly: structured reds around 16 to 18 degrees, light fruity reds a little below, dry whites 10 to 12, sparkling colder still at around 8. If in doubt, a quarter of an hour in the fridge has never hurt a red.
The third is context. You do not need silence, but tasting while watching television will cost you half of what the wine has to say.
Colour already tells you a lot
Tilt the glass over something white, or just hold it to the light. Colour is not decoration: it carries age, grape and method. A young white is nearly transparent with green reflections. As it ages it turns golden, then amber. A young red has intense purple at the edge; over the years it moves to garnet and then to brick.
A white with strong golden reflections on a young label tells you it saw wood, or came from a hot vintage. A red already orange at the rim on a bottle only a few years old suggests either poor storage or a grape that evolves fast by nature, like Pinot Noir, which loses colour long before Sangiovese or Nebbiolo would.
Clarity is another signal. Filtered wines are bright. Unfiltered ones can carry a light haze, which is a production choice rather than a fault. Sediment at the bottom of an old red bottle is entirely normal.
How to smell wine without looking peculiar
Smell the wine before you swirl it. Then swirl, a couple of turns is plenty rather than a frenzy, and smell again. The difference is real: the first nose gives you the most volatile aromas, the ones that leave first. The second, after oxygen has opened the wine, goes deeper.
What should you look for? At first, nothing specific. Close your eyes, smell, and describe whatever arrives, even if the first thing in your head is wet earth or chewing gum. That is your starting point, and a vocabulary you built yourself is far more useful than one borrowed from a tasting note.
Aromas fall into three families. Primary come from the grape: fruit, flowers, herbs. Secondary come from fermentation: yeast, bread crust, butter. Tertiary develop with age in bottle or wood: spice, tobacco, leather, earth, mushroom. A young fresh wine is mostly primary, an old one mostly tertiary, and where a wine sits on that scale tells you where it is in its life.
The mouthful: what actually happens
Take a reasonably generous sip, not a whole gulp and not the minimal medicinal taste. Let it move across the whole mouth rather than the tip of the tongue.
The first things you register are the attack, that immediate impression, and the acidity. Acidity is what makes you salivate. It is not a fault: it is why wine works with food, cleaning the palate and preparing the next bite. A white without acidity is flat and will not last five minutes at a table.
Reds add tannin: the compounds that dry the mouth, like biting a grape skin or drinking very strong tea. They can be velvety and soft, as in a ripe Merlot, or scratchy and firm as in a young Barolo. Neither is automatically better. It depends on the wine, the vintage and how long it has had.
Then there is length: how long the flavour stays after you swallow. Tasters count it in seconds. It is one of the more reliable indicators of quality and one of the easiest to notice once you start paying attention to it.
The four elements that build a wine
Structure means acidity, tannin, alcohol and sweetness, and how they balance each other. A wine with plenty of acidity but little tannin or alcohol can feel thin and nervous. One with high alcohol and no tannin feels hot and slack. When none of them dominates, you have a wine that works.
Alcohol registers as warmth, mostly on the finish and in the throat. It is not a fault in itself, and a wine with too much of it relative to everything else tires you quickly. Residual sweetness, the sugar left after fermentation, is not only found in dessert wine: certain ripe reds have a roundness that reads as sweetness without being sugar.
Recognising these four and naming what you feel, even approximately, is most of the skill. You do not need to become a chemist.
How much does food matter?
A great deal, and it is usually left out of descriptions of method. Tasting a wine alone gives you information; tasting it at a table shows you its character. Wines that seem hard and austere on their own transform with the right food. The reason is chemical: acidity balances fat, tannins bind with the proteins in meat, sweetness offsets salt.
The rule that always works is matching intensity: a delicate dish wants a light wine, a rich one carries structure. The second useful principle is contrast: fatty food with acidic wine, salty food with a touch of residual sweetness. These are starting points, not doctrine.
Faults: recognising them without fear of being wrong
Not every bottle is good, and spotting a fault is consumer protection rather than snobbery. The most common and the easiest to identify is cork taint. Damp cellar, wet cardboard, mould. It is not subtle. If you smell it you are entitled to send the bottle back in a restaurant or ask the shop for a refund, and both are routine requests rather than confrontations.
Oxidation is the other frequent one. An oxidised white has lost its fruit and smells of baked apple, vinegar or excessive walnut, and the colour is darker than the vintage should give. In reds it brings stewed prune and a flat structure. It comes from bad storage or from a bottle open too long.
Then there is reduction: egg, burnt rubber or sulphur on opening. Often it is not permanent. Swirl the wine hard or leave it a few minutes and it usually disappears. If it persists, the problem is deeper.
Training yourself without spending a fortune
The good news is that you do not need great vintages to learn. Opening something very complex early on tends to confuse rather than teach. Start with clean varietal wines that express their grape without too many layers.
The exercise we recommend most is comparative tasting: open two bottles of the same grape from different producers or areas and drink them side by side. Differences become enormous and obvious when the comparison is in the next glass. A Verdicchio from the Marche against a Greco di Tufo teaches you more about the influence of place than any book.
None of this needs expensive labels. Keep a notebook, or notes on a phone, and write down what you smelt and tasted before reading anyone else's description. Reading first tells you what to find, which is the opposite of learning.
When decanting helps and when it does not
Decanting looks like a complicated rite and has a simple logic. It does two jobs: separating an old red from its sediment, and opening young closed wines that need oxygen. Not every wine needs either. A fresh aromatic white, a sparkling wine or a light red to be drunk young gains nothing from an hour in a decanter.
Reds with serious tannin and structure gain a great deal, particularly when young. A Barolo of three or four years poured straight into the glass often reads as hard and unfriendly. The same wine after forty-five minutes in a decanter opens and softens. That is controlled oxidation rather than magic.
For old wines with sediment the technique is different. Pour slowly with a light behind the neck of the bottle, and stop when you see the sediment approaching. The aim there is separation, not aeration, and too much air on a very old wine can flatten it within minutes.
Sparkling wine: the same method with additions
The method works for sparkling too, with a few extra things to notice. The bubbles are part of the experience: they should be fine, persistent and numerous. Large coarse bubbles usually mean lower quality or poor storage. Watch the thread rising from the base of the glass and how long it lasts.
On the nose, bubbles carry aroma more directly. Classic-method sparkling, Franciacorta, Trento DOC or Alta Langa, tends to give bread crust, yeast, white-fleshed fruit and citrus. Tank-method Prosecco gives fresher, more immediate aromas: green apple, white flowers, sometimes a herbal touch. Different styles, not a ranking.
In the mouth, look for the balance between acidity and softness, and for the length of the finish. Well-made sparkling finishes dry and clean rather than cloying.
Domande frequenti
Do I have to spit the way professionals do?
Professionals spit because they taste dozens of wines in a session. With one or two, swallow. The finish in the throat is part of the experience. Spit when the quantity is large and you need to stay sharp.
How long should I wait after opening a bottle?
It depends on the wine. A young closed one gains from twenty minutes of air in the glass. A mature one that is already open should be drunk. If unsure, taste at opening and again ten minutes later and you will notice the difference yourself.
What if I cannot smell anything?
First check: the wine is too cold, and cold locks aromas away. Warm the glass in your hands for a few seconds and try again. Second: your nose has adapted. Move the glass away, breathe neutral air, come back. Third: swirl more before smelling.
How do I know if a wine is improving with age or just fading?
A wine that is improving develops complexity: tertiary notes of leather, tobacco and earth weave into the original fruit. A wine that is fading loses fruit and liveliness without gaining anything. If all you find is tiredness and flatness, the moment has passed.
Are tasting courses worth it, or can I learn alone?
You can learn very well alone with practice and some good reading. A course has one real advantage: it puts many wines in front of you at once, guided by someone who knows what to look for. Start with comparative tastings at home if you would rather not pay for one.
Can I order the wines used in these exercises from outside Italy?
Comparative tasting works with whatever your local retailer stocks, and it does not need to be Italian at all. If you want the Italian comparisons, Verdicchio, Soave and Chianti are widely exported while Greco di Tufo needs a specialist. The shop linked on this page ships to 41 countries, including the whole EU, the UK, Switzerland and Norway, so ordering from outside Italy is straightforward. Worth checking your own country is on their list before filling a basket.
