To taste wine, you look at it, swirl it, smell it, taste it and then decide what you think, in that order. The steps slow you down long enough to notice what’s actually in the glass: fruit, acidity, tannin, sweetness and how long the flavor lasts. You don’t need special training or an expensive bottle, just a clean glass, good light and a few wines to compare.

The method below follows the structure the Wine & Spirit Education Trust (WSET) teaches in its Systematic Approach to Tasting, which splits tasting into appearance (how the wine looks), nose (how it smells) and palate (how it tastes), followed by conclusions. We’ve added practical tips from Wine Folly and from winery guides.

Before you start

WSET’s course guidance asks students not to wear perfume or bring strong-smelling food, and to have clean glasses, water and spittoons ready before a tasting begins. At home, that translates to:

  • Neutral light and a white background, such as a napkin or sheet of paper, for judging color.
  • The same glass for every wine, so you compare the wines and not the glasses.
  • Small pours. We’d fill the glass a third of the way at most, so there’s room to swirl.
  • Water and a spit cup on the table.
  • No strong smells nearby: no candles, perfume or cooking.

Step 1: Look

Tilt the glass over the white background and check three things:

  • Clarity. WSET notes that most wines are clear, and that haziness can point to a fault or a winemaking choice.
  • Color. WSET’s scale for whites runs from lemon-green through lemon, gold and amber to brown; for reds, from purple through ruby and garnet to tawny and brown. Wine Folly explains that white wines tend to deepen in color as they age, while reds lose color.
  • Intensity. How deep the color is, from pale to deep.

Wine Folly suggests spending only a few seconds here.

Step 2: Swirl

Swirling releases more aroma compounds into the air in the glass, according to Wine Folly. Visit Napa Valley suggests keeping the base of the glass on the table and moving it in small circles if you’re worried about spilling. A few seconds is enough.

Step 3: Smell

Put your nose into the glass and take a sniff. Wine Folly recommends alternating short and long sniffs and, if your nose gets tired, smelling your own forearm to reset it.

Start broad, then narrow down. Rather than hunting for “blackberry” straight away, ask whether the fruit is citrus, orchard (apple, pear) or tropical in a white, or red, black or blue fruit in a red. Then get specific.

WSET and Wine Folly both sort aromas into three groups:

TypeWhere it comes fromExamples (Wine Folly)
PrimaryThe grapeFruit, flowers, herbs
SecondaryWinemaking, such as fermentationBread, yogurt, cheese rind
TertiaryAging in oak or bottleVanilla, baking spice, nuts, leather, dried fruit

Smell is also where faults show up first. WSET lists cork taint, closure failure and heat damage among the problems tasters learn to spot. Visit Napa Valley describes corked wine as smelling of damp, wet or rotten cardboard.

Tip: An aroma kit with small vials of common wine scents helps train your nose. Our guide to the best wine tasting kit compares options.

Step 4: Taste

Take a sip big enough to coat your mouth, then smaller sips to pick out details, as Wine Folly suggests. WSET teaches students to draw a little air through the wine in the mouth and to bring the aromas to the back of the palate, because, as its course guidance puts it, flavors are detected by the nose, not the tongue. The tongue itself picks up only sweetness, acidity, bitterness, salt and umami.

Work through the structure:

ElementWhat to noticeUseful reference points
SweetnessIs there any sugar?Wine Folly: most people only perceive sweetness above about 4 g/L, and dry wines are generally under about 10 g/L
AcidityHow much your mouth watersWSET: how long the watering lasts is a good guide to acidity
Tannin (reds)A drying, grippy feel on gums and tongueWSET compares it to strong black tea; Wine Folly lists Pinot Noir as low and Cabernet as high
AlcoholWarmth in the throatWSET: low is under 11% ABV, medium 11–13.9%, high 14% and above
BodyWeight in the mouthWSET: a mix of alcohol, tannin and sugar; Wine Folly compares light to full body with skim and whole milk
FlavorsDo they match the nose?Compare with what you smelled
FinishHow long the flavors last after you spit or swallowWSET: short, medium or long

Step 5: Conclude

Now put it together. WSET judges quality on four points:

  • Balance: alcohol, acidity, sugar and tannin working in harmony, as Visit Napa Valley’s glossary defines it.
  • Length: how long the flavors linger and develop after you spit.
  • Intensity: how pronounced the aromas and flavors are.
  • Complexity: how many different aromas and flavors you can find.

WSET is careful to separate this from personal taste: a quality assessment is not about how much you like a wine. Wine Folly’s version adds the personal question too. Did you like it, and what made it memorable? Sum the wine up in a few words. In our view, that one-line summary is the most useful habit you can build, because it’s what you’ll remember next time you shop.

Tasting vocabulary

TermWhat it means
AcidityThe tart, mouth-watering quality; low acidity can taste flat or “flabby”
BalancedAll the parts work in harmony
BodyHow heavy the wine feels: light, medium or full
CorkedSpoiled by cork taint; smells of damp cardboard
DryNo noticeable sweetness
Finish (length)How long the flavors last after the wine is gone
MouthfeelTexture: silky, smooth, rough or chewy
NoseThe wine’s aromas
TanninDrying compounds from grape skins, seeds and oak
Primary, secondary, tertiaryAromas from the grape, the winemaking and aging

Most of these definitions follow Visit Napa Valley’s tasting glossary and WSET’s course guidance.

To spit or not to spit

Spitting is normal, not rude. WSET’s course guidance explains to students why a spittoon is needed when tasting, and its finish assessment assumes you spit. Visit Napa Valley’s advice is to spit into the dump bucket if you don’t want to get intoxicated, and Wine Spectator’s tasting-room guide says to pour any leftover wine from your glass into the bucket on the counter.

We’d spit whenever you’re tasting more than a couple of wines. Spitting cuts how much you drink but doesn’t make driving safe, so on a winery day, book a driver.

Tasting at home vs at a winery

At home you control everything: the same glasses, the right temperature, a slow pace and side-by-side comparisons, which Wine Folly calls the fastest way to learn. Keep notes and, once you’re comfortable, try tasting blind with the labels covered.

At a winery the staff pour and explain, and you get to taste wines you might never buy unseen. Some practical points:

  • Book ahead. Visit Napa Valley says popular wineries can fill their reservations weeks in advance, and some small wineries need to know you’re coming.
  • Expect a fee. Visit Napa Valley puts the average basic tasting in Napa at about $40, from around $20 to $200 or more for tours or food. Some wineries waive the fee if you buy wine.
  • Pace yourself. Visit Napa Valley recommends two or three wineries a day, since most visits take at least 90 minutes, and suggests hiring a driver or tour company.
  • Share and make space. Wine Spectator’s guide says it’s generally fine for a couple to share a taste, and suggests stepping away from a busy counter once you’ve been poured.
  • Skip the perfume. It masks the wine’s aroma for you and everyone nearby.

A simple tasting flight to try at home

A flight is a set of wines poured side by side. Three or four is plenty for a first try. Each pair below isolates one thing, so the differences are easy to notice:

FlightWinesWhat we’d look for
1. AcidityA crisp Sauvignon Blanc vs an oaked ChardonnayHigh vs softer acidity, and what oak adds to aroma and body
2. TanninA Pinot Noir vs a Cabernet SauvignonLow vs high tannin (Wine Folly’s examples)
3. SweetnessA dry Riesling vs an off-dry RieslingHow sugar changes the taste of the same grape

We’d pour light to full and dry to sweet: whites before reds, the sweeter wine last. Cover the labels if you can, write a one-line note for each wine, then reveal them and compare. We’d keep each pour small, have water and bread on the table, and spit freely. For more on reading what other tasters say, see how wine ratings work.

Wine tasting is for adults of legal drinking age (21 in the US). Please taste responsibly and never drive after drinking.

Frequently asked questions

What are the steps of wine tasting?

Look at the wine's color and clarity, swirl it to release aromas, smell it, taste it for sweetness, acidity, tannin, alcohol, body and finish, then draw a conclusion about balance and quality. WSET's Systematic Approach to Tasting groups these as appearance, nose, palate and conclusions.

Why do people swirl wine?

Swirling releases more aroma compounds from the wine into the air in the glass, so you can smell more. If you're worried about spilling, keep the base of the glass on the table while you swirl.

Is it rude to spit at a wine tasting?

No. Spitting is standard practice at tastings, and wine courses expect students to use a spittoon. Visit Napa Valley suggests spitting into the dump bucket if you don't want to get intoxicated.

How many wines should you taste at once?

We'd suggest three or four wines side by side for a home flight: enough to notice differences without tiring your palate. At wineries, Visit Napa Valley recommends two or three visits a day.

What does finish mean in wine tasting?

The finish, or length, is how long the wine's flavors linger after you swallow or spit. WSET grades it as short, medium or long and uses it as one of its four quality markers.
