What Wine Goes With Salad and Vinaigrette?

A white with more acidity than the dressing. Sauvignon Blanc, Grüner Veltliner, Vinho Verde or Assyrtiko — all four have acidity to spare, which is precisely what the dressing is asking for.

Under EU rules nothing may be sold as wine vinegar below 6% acetic acid, and most bottles sit at 6 to 7%. A dry white wine carries somewhere between 5 and 8 grams of acid per litre — well under 1%. The dressing in the bowl is close to ten times as sour as the glass in your hand — and sourness in food does something counter-intuitive to wine: it makes the wine taste less acidic, rounder and softer. A wine with only ordinary acidity does not survive that subtraction. It arrives flat, faintly sweet and dull.

Read the dressing before you read the label

Two off any shelf, two worth going to find

The pair you can buy anywhere. Sauvignon Blanc is the default and earns it — grassy, gooseberry-scented, and still recognisably sharp after the dressing has taken its cut. Sancerre is the flinty, restrained reading of the grape; Marlborough is the loud one, and the loud one copes better with a heavy hand on the vinegar. Next to it, Vinho Verde from Portugal's Minho: typically 8.5 to 11% alcohol, faintly spritzy, and by a distance the cheapest thing here that actually works. The low alcohol is doing quiet work — there is no warmth to turn sour once the acid stacks up.

The two worth a detour. Grüner Veltliner has a white-pepper bite and a herbal streak most whites simply do not offer, and it is what to open when the bowl contains something awkward — asparagus, raw fennel, a fistful of dill. Assyrtiko is the extreme end: unusual among white grapes in keeping searing acidity even when grown somewhere genuinely hot. On Santorini the vines are still ungrafted, coiled into ground-level baskets the growers call kouloura, because the island's clay-free volcanic ash never let phylloxera take hold.

What else is in the bowl

Artichoke is the famous saboteur. Eat a few leaves and the next sip of anything — water included — can come back oddly sweet, which leaves a bone-dry white reading as off-dry. It does not happen to everybody: the 1972 study in Science that put the effect on record found roughly 60% of tasters got it and the rest noticed nothing at all, so half your table may wonder what you are talking about. Cynarin and chlorogenic acid, the compounds behind the artichoke's own bitterness, are the usual suspects, and the leading explanation is that they block the sweet receptors until a swallow washes them off. The remedy is not in dispute: a mouthful of water between bites resets the palate.

Asparagus turns a great many whites tinny and metallic. Grüner Veltliner is the standard exception, which is why Austrians drink it all the way through asparagus season.

Radicchio, chicory and rocket bring bitterness of their own — lactucin and lactucopicrin in the chicory family, glucosinolates in rocket — and none of it cancels the bitterness already sitting in a glass of red. That, rather than the vinegar, is the main reason red struggles here.

Change the salad, not the wine

Two fixes, both easy. Cut the vinegar back to four or five parts oil to one part acid instead of the textbook three. Or replace the vinegar altogether with verjus — the juice of unripe grapes, sharp but made of grape acid rather than acetic acid, which is exactly why it leaves wine alone.

If I have opened a bottle I actually care about, I dress the salad with verjus, good olive oil and salt, and leave the vinegar in the cupboard. And skip the soft, low-acid whites entirely: a gentle Pinot Grigio that tastes pleasant on its own is stripped of what little lift it had and finishes sweetish and short.
