Wine acidity by type

15 common styles, sorted from the lowest-acid to the highest. The band is derived straight from each wine's place on the 1–5 low-to-high acidity scale.

WineAcidity (1–5)Level
ViognierA plush, perfumed white with ripe stone-fruit richness and famously low acidity — about the softest dry white you can buy.1.8 / 5Low acidity
GewürztraminerAromatic and oily-textured, with lychee and rose; low acidity is part of its exotic, almost unctuous character.2 / 5Low acidity
GrenacheA warm-climate red picked ripe and sweet-fruited; soft, low-acid and round, which is why it anchors so many GSM blends.2.4 / 5Low acidity
Chardonnay (oaked)Malolactic fermentation converts sharp malic acid into soft lactic acid, so a buttery, oaked Chardonnay feels rounder than its unoaked, Chablis-style self.2.6 / 5Medium acidity
ZinfandelPicked very ripe and high in alcohol, jammy Zinfandel keeps only moderate acidity under all that sweet fruit.2.7 / 5Medium acidity
Shiraz (warm-climate Syrah)Dense and ripe from warm regions, with medium acidity balancing its tannin and alcohol — tarter, cooler-climate Syrah sits a notch higher.2.9 / 5Medium acidity
MalbecVelvety, dark-fruited and smooth; medium acidity keeps it drinkable without the zing of a cool-climate red.3 / 5Medium acidity
MerlotA rounded, plummy red that sits squarely in the medium range — enough acidity for food, softer than Cabernet.3.1 / 5Medium acidity
Cabernet SauvignonStructured and firm, with medium-to-high acidity working alongside its tannin to give the wine its classic ageworthy backbone.3.3 / 5Medium acidity
Pinot NoirThe high-acid red: thin-skinned and usually cool-climate, its bright, mouth-watering acidity is what makes it so food-friendly.3.7 / 5High acidity
Pinot GrigioA crisp, light, unoaked white built on fresh acidity — zippy and refreshing rather than rich.3.9 / 5High acidity
Sangiovese (Chianti)The savoury, cherry-and-tomato Italian red whose high acidity is tailor-made for the table — it practically demands food.4.1 / 5High acidity
Sauvignon BlancZesty, green and citrus-driven; searing natural acidity is the whole point of the style.4.4 / 5High acidity
Riesling (dry)One of the highest-acid grapes of all — racy and electric. Note that acidity is not sweetness: even a sweet Riesling is bracingly high-acid.4.6 / 5High acidity
Brut sparklingChampagne, Cava and traditional-method fizz are made from early-picked, very high-acid grapes; the acidity is what keeps the bubbles crisp.4.8 / 5High acidity

Acidity is the tart, mouth-watering freshness in a wine. In the lab it is measured as titratable acidity (grams per litre) and pH, but how tart a wine actually tastes is balanced by its sugar, alcohol, and ripe fruit — so each style shows its typical place on the standard 1-to-5 low-to-high acidity scale, and the band (Low / Medium / High) and the lowest-acid-first order are derived straight from that score by fixed cut-offs, so the ranking can't drift from the numbers. Treat it as a guide: a cool vintage or an early pick makes any wine tarter, while a warm climate, riper fruit, oak, and malolactic fermentation soften it. Last reviewed 2026-10-02.

High acid isn't sour

In a balanced wine, acidity reads as freshness and length — the lift a squeeze of lemon gives a dish — not sourness. It's also independent of sweetness: a great sweet Riesling is bracingly high-acid, which is exactly what stops it tasting cloying. And as a rule, white wines carry more acidity than reds.

Wine acidity — FAQ

What is acidity in wine?

Acidity is the tart, crisp, mouth-watering sensation in a wine — the same zing you get from a squeeze of lemon. It makes a wine feel fresh and lively and keeps it from tasting flat or flabby, and it's one of the core structural elements sommeliers taste for, alongside sweetness, tannin, body, and alcohol. It's measured in the lab as titratable acidity (grams per litre) and pH, but how tart a wine tastes also depends on how much sugar, alcohol, and ripe fruit is balancing it.

Which wines are highest in acidity?

Brut sparkling wines (Champagne, Cava, traditional-method fizz) are the highest-acid of all, made from early-picked grapes. Zesty, cool-climate whites come next — Riesling, Sauvignon Blanc, and Pinot Grigio — and among reds, Sangiovese (Chianti), Nebbiolo, and Pinot Noir carry the brightest acidity. As a rule, white wines tend to be more acidic than reds.

Which wines are lowest in acidity?

The softest, lowest-acid wines are ripe, aromatic whites like Viognier and Gewürztraminer, and warm-climate reds picked very ripe — Grenache and jammy Zinfandel, along with buttery, malolactic-fermented oaked Chardonnay. Warm sunshine, riper fruit, and oak all soften a wine's acidity.

Are red or white wines more acidic?

White wines are generally more acidic than reds. Whites are usually fermented without softening malolactic conversion and are often made in a fresh, early-picked style, so they keep more of their natural tartness. Reds more often go through malolactic fermentation and come from riper fruit, which rounds the acidity off. There are exceptions on both sides — a cool-climate Pinot Noir can out-zip a ripe Chardonnay.

Does high acidity mean a wine is sour?

No. In a balanced wine, acidity reads as freshness and length, not sourness — the way lemon lifts a dish rather than ruining it. A wine only tastes sour when its acidity has nothing to balance it. High acidity is actually a good thing: it makes wine food-friendly and is one of the key reasons a wine can age well.

Is acidity the same as sweetness?

No — they're independent. A wine can be high in both: a great sweet Riesling is bracingly high-acid, which is exactly what keeps it from tasting cloying. Acidity is the tart, fresh element; sweetness is sugar. When they're in balance the wine feels harmonious rather than either sharp or sugary.

Which wines are lowest in acid for a sensitive stomach?

If you're looking for gentler, lower-acid wines, this chart's Low band is the place to start: soft, aromatic whites like Viognier and Gewürztraminer, and ripe, warm-climate reds such as Grenache. This is a flavour guide, not medical advice — if acidity genuinely bothers you, talk to a doctor.
