Twelve themes for a blind tasting.

Most blind tastings go wrong before the first bottle is poured. The host opens six good wines that have nothing to do with each other, the guesses are random and the reveal is a list of labels. Nobody leaves knowing more than when they arrived. The blind wine tasting ideas that work share one principle: change one thing and hold everything else still, so that every difference in the glass has a cause you can name.

Below are twelve themes, grouped by who is at the table, each with the lesson it teaches and a note on building the flight. Six wines suit most of them. Glasses, pours, spittoons, food and timing are covered in how to host a blind tasting for twelve. Why tasting without labels changes your judgement at all is the subject of what blind tasting teaches.

Blind wine tasting ideas for a mixed group

These four work when experience around the table varies, which makes them the natural choice for a corporate wine tasting as well as a dinner with friends.

• Grape varieties 101. Pour wines from six classic grapes: Sauvignon Blanc, Riesling and Chardonnay, then Pinot Noir, Syrah and Cabernet Sauvignon. Tell the table the six names and ask them to match each glass to one. Every grape has a signature that colour and structure reveal as often as aroma does, such as the acidity of Riesling, the pale colour of Pinot Noir or the firm tannin of Cabernet. Choose textbook examples from classic regions over the most unusual bottles you can find.
• Oak or no oak. Three Chardonnays of similar quality, one made without oak, one with a light touch and one with plenty of new oak. A basic Chablis often makes a good unoaked anchor, since most is made without oak, but ask your merchant because practice varies by producer. The flight shows what oak adds (vanilla, toast, spice, a rounder texture) and what it can hide. Buttery notes, which many tasters blame on oak, often come from malolactic conversion instead.
• Champagne against other sparkling wines. Two Champagnes against a Crémant, a Cava, a traditional method wine from England or Tasmania and a Prosecco. Method matters as much as place. A second fermentation in bottle and long ageing on the lees bring notes of toast and brioche, while most Prosecco has its second fermentation in large pressurised tanks and tastes of fresh fruit and flowers. Serve everything at the same temperature and in the same glass so that neither becomes the clue.
• Sweet wines. A Sauternes, a Tokaji Aszú, a sweet German Riesling, an Eiswein, a Pedro Ximénez Sherry and a tawny Port. There are several routes to sweetness (late picking, noble rot, frozen grapes, dried grapes and fortification) and acidity decides whether a sweet wine tastes fresh or cloying. Pour small, around 50 ml, because a little goes a long way.

Four themes for people who taste regularly

• Old World against New World, one grape. Three pairs: Sancerre against Marlborough Sauvignon Blanc, red Burgundy against Pinot Noir from Oregon or Central Otago, Northern Rhône Syrah against Barossa Shiraz. The lesson is about climate and winemaking more than hemispheres. Riper fruit and higher alcohol tend to point to a warmer place, but cool New World sites and hot European vintages blur the line every year.
• One grape, six countries. Chardonnay or Syrah from six countries, at a similar level of ambition. It separates what the grape always brings from what place and producer add on top. Keep prices within a narrow band so the evening does not turn into a price guess.
• The price trap. A modest bottle against a famous one of the same grape and region, hidden among four other wines of the same style. Ask every guest to write down what they would pay for each wine before the reveal. The result is uncomfortable and valuable, because it shows how much of what you taste is really the label and the price. It is also the fastest way to find wines that deliver more than they cost.
• Left Bank against Right Bank. Three red Bordeaux from the Médoc or Pessac-Léognan against three from Saint-Émilion or Pomerol, all from one vintage. The contrast is grape and soil, Cabernet Sauvignon on gravel against Merlot and Cabernet Franc on clay and limestone. Expect firmer tannin and blackcurrant on one side and rounder, plummy fruit on the other, then enjoy the argument about the exceptions. The map behind it is set out in Bordeaux's two banks and its classifications.

Four themes for collectors

• A horizontal. One vintage, one appellation, six producers. With vintage and origin fixed, house style, ripeness and oak choices stand out clearly, which shows how much the producer matters. Choose a vintage that is drinking well now.
• A vertical. One wine across six vintages, ideally a run of consecutive years. It teaches vintage character: how a cool year, a hot year and a wet harvest show in the same wine from the same site.
• The age ladder. Two wines, each at five, ten and twenty years old (or as close as you can get). Where the vertical teaches vintage, the ladder teaches time. In a red, the colour moves from purple towards garnet and brick at the rim, fruit gives way to savoury notes and the tannin softens. Provenance matters more here than anywhere, because a badly stored bottle teaches the wrong lesson.
• Neighbours. Two or three pairs of neighbouring vineyards or villages, each pair from the same producer and the same vintage. With grower, year and winemaking fixed, the site is the only thing that changes, which makes this the purest lesson in what terroir means in the glass. The differences are subtle, so taste each pair side by side and slowly.

Scoring and the reveal

By default, keep the theme to yourself and score on the usual four columns of grape, region, vintage and price. Announcing the theme answers too many of those columns before anyone tastes. When you do want to announce it, change the question to one the theme leaves open:

• Matching (grape varieties 101, one grape in six countries, sweet wines): give the table the six names, then a point for each glass matched correctly.
• Ordering (the vertical, the age ladder, oak or no oak): a point for each glass in the right position.
• Sorting (neighbours, Old World against New World, Left Bank against Right Bank, Champagne against other sparkling wines): a point for each wine put on the right side.
• Estimating (the price trap): the closest total across all six wines wins.

Naming the grape is no test once the table knows every glass is Chardonnay; ranking the glasses from least to most oak still is. At the reveal, say the lesson out loud as each bottle comes out of its bag: which glass held the famous bottle, what the oak did, which neighbour was which. A reveal without the lesson is just a list of labels.

Choosing the theme for your table

Start from the lesson you want people to take home and work backwards to the bottles. A group of beginners learns more from grape varieties 101 than from a vertical they cannot yet read. Regular tasters enjoy the arguments in Old World against New World or Left Bank against Right Bank. Collectors get the most from a vertical or an age ladder, which doubles as an honest check on their own cellar.

Choose the lesson first and the wines second.

A week before, send guests our free wine quiz as a warm-up; their scores tell you which of the three groups you are really hosting. If you would rather taste than organise, we run the blind tasting format for private and corporate groups.
