Download freeThe three measures that matter
Strip away the poetry and most of what a wine feels like comes down to three measurable things. Tannin is the drying grip from skins, seeds and oak, the sensation that makes your gums feel like they have been lightly sanded after a young Nebbiolo. Acidity is the mouth-watering freshness that has you salivating after a sip of Sauvignon Blanc. Body is sheer weight in the mouth, driven mostly by alcohol: the difference between skimmed milk and whole milk, poured from a wine bottle. The chart above scores 31 classic styles on all three, plus sweetness, using textbook-typical values; the glossary entry on tannins goes deeper on the chemistry.
How to taste each one
They separate cleanly once you know where to look. For tannin, wait until after you swallow and drag your tongue across your gums: the rougher and drier they feel, the higher the tannin. For acidity, tip your head forward slightly and notice how much saliva pools; high-acid wines set your mouth streaming. For body, ignore flavour entirely and ask only how heavy the liquid feels. Sweetness announces itself on the tip of the tongue first, which is why it gets a whole sweetness chart of its own. This order of operations, sight, nose, then palate attribute by attribute, is exactly the drill on the WSET Level 2 tasting sheet if you want the formal version.
Using structure to find new wines
Structure, not flavour, is the reliable way to branch out. If you love Malbec, the chart shows Shiraz and Mourvèdre sitting on almost identical scores, which is why they feel like cousins even though the fruit differs. If big reds feel harsh, sort by tannin, start at the bottom, and work upwards through Gamay, Valpolicella and Pinot Noir; there is a full guide to low-tannin red wines for that journey. And if a wine you disliked was ever described as flabby or aggressive, the fault was almost certainly a structure mismatch rather than the grape itself. Open any wine above, note the two or three scores that define it, and the suggestion line will hand you the next bottle.
