Fruity is not the same as sweet

Why the confusion is so persistent

Your brain does not keep smell and taste in separate boxes. Retronasal aroma — the smell reaching your nose from inside your mouth — is combined with what your tongue reports into a single impression called flavour, and there is no introspective way to pull the two apart. When a wine smells intensely of ripe peach, the sweetness you seem to taste is partly your brain filling in what a peach usually implies.

The effect is well demonstrated: adding an aroma associated with sweetness makes people rate a solution as sweeter without any change in its sugar content. It is not a failure of attention, and being told about it does not make it go away. It simply means the word “sweet” is doing two jobs and people are using it for both.

Three other things get folded into it. Alcohol tastes faintly sweet at the concentrations found in wine, so a 15% red reads as sweeter than a 12% one made the same way. Oak contributes vanillin, which is literally the compound in vanilla, and vanilla is something almost nobody meets outside dessert. Low acidity removes the counterweight, so a soft wine tastes rounder and therefore sweeter than a sharp one with identical sugar.

What this costs a reader in practice

Someone who dislikes sweet wine asks for something dry, is handed a bone-dry Australian Shiraz, finds it tastes sweet, and concludes either that the shop was wrong or that they cannot trust the word. What they actually dislike is ripe fruit, or oak, or high alcohol — all of which are askable for by name.

It runs the other way too. Someone who thinks they hate sweet wine has usually met a cheap one with sugar and nothing else. A German Kabinett carries real sugar and enough acidity that most people do not register it as sweet at all, and it is one of the most food-friendly things in a wine shop.

This is why WineHQ keeps the two apart everywhere it can. In the taste model, sweetness and fruit intensity are separate dimensions with separate bands. In the discovery refiner, the rich dark fruit and the touch of sweetness are separate things to like — so a reader can ask for one without getting the other.

Bone dry, and unmistakably fruity

Every one of these carries the catalogue’s lowest sweetness rating and its highest or near-highest fruit intensity. If you have described any of them as sweet, this is the distinction in front of you.

Medium-bodied dry red · Full-bodied dry red · Aromatic dry white · Rich, oaked white · Dry rosé · Northern Rhône Syrah · Southern Rhône blend · Châteauneuf-du-Pape · Loire Cabernet Franc · Beaujolais · Cru Beaujolais · Languedoc red · Langhe Nebbiolo · Barbera · Chianti Classico Gran Selezione · Brunello di Montalcino · Rosso di Montalcino · Super Tuscan

Genuinely sweet, and not remotely cloying

These contain substantial sugar and enough acidity to carry it. Sweetness without acidity is what people mean by cloying; sweetness with it is what makes Sauternes and Riesling last for decades.

How to tell them apart in the glass

1. Smell it, then hold your nose and taste it. Pinching your nostrils shut removes retronasal aroma almost entirely. Sugar is still there; the peach is not. It is a crude test and it works.
2. Notice where you feel it. Sweetness registers on the tongue, mostly at the front. Fruit registers as a smell, and you will notice it changes as you breathe out.
3. Check whether it lingers as weight. Residual sugar leaves a faint coating and a slight viscosity. Aroma does not.
4. Read the back label sceptically. “Fruit-forward” and “ripe” describe aroma. “Off-dry”, “medium” and the sweetness scale on supermarket shelf-talkers describe sugar. They are not interchangeable and producers generally use them correctly.

Where to go next

• The sweetness decoder — what Brut, Sec, trocken and Spätlese actually mean, and which of them the law defines.
• The wine finder — filter on sweetness and fruit intensity separately, and see what falls out.
• The taste model — why the two are separate dimensions rather than one.
