Low Sugar Wine: Driest Styles and How to Read the Label

The lowest-sugar wines are dry still wines and the driest sparkling styles, such as Brut Nature and Extra Brut. In a dry wine, yeast has turned nearly all the grape sugar into alcohol: USDA FoodData Central lists under a gram of sugar in a 5-ounce glass of red table wine. The trick is knowing which wines are dry, because US labels rarely say. This guide explains residual sugar, names the driest styles, decodes the label words and gives USDA’s sugar figures per glass.

Note: This guide is about wine styles and labels. It isn’t diet or medical advice. If you’re watching sugar for a health reason, ask your doctor.

What residual sugar is

Grapes are full of sugar, and fermentation is yeast turning that sugar into alcohol. Wine Folly defines residual sugar (RS) as the natural grape sugar left over when fermentation ends. It is measured in grams per liter (g/L). Wine Folly gives a handy conversion: 10 g/L is 1% sweetness, which works out to about 1.8 grams of carbohydrate in a 5-ounce (150 ml) glass.

So a wine with 2 g/L of residual sugar holds about 0.3 grams of sugar per glass, while one with 50 g/L holds about 7.5 grams. We calculated those from Wine Folly’s conversion (grams per liter × 0.15 liter).

Two things make a wine seem less sweet than its sugar suggests. Wine Folly explains that acidity and bitterness mask sweetness, the way lemon juice balances sugar in lemonade. That is why a high-acid Riesling with a few grams of sugar can still taste dry.

How much sugar is in a glass of wine?

USDA FoodData Central, the US government’s food composition database, lists sugar for several wine types. We converted its figures per 100 grams to a serving using USDA’s own portion weights (147 grams for 5 ounces of red or white, 103 grams for a 3.5-ounce glass of dessert wine):

Wine (USDA entry)	Serving	Total sugars
Red table wine	5 fl oz	About 0.9 g
White table wine	5 fl oz	About 1.4 g
Sweet dessert wine	3.5 fl oz	About 8.0 g

These are averages for a style, not the bottle in your hand. An off-dry rosé or red can have more sugar than the table shows.

The driest styles

Still wines

Wine Folly notes that many European wine laws require a region’s wines to stay under 4 g/L, making them dry by law, and names Pinot Grigio, Sancerre and Albariño as examples. It adds that high-acid wines such as dry German Riesling and dry Hungarian Furmint can carry a little more sugar and still taste dry.

In our view, the safest low-sugar choices on a US shelf are classic European dry whites and traditional varietal reds such as Cabernet Sauvignon, Pinot Noir and Tempranillo, as our dry red guide explains. We’d be more careful with inexpensive red blends: Wine Folly says some high-volume bulk reds keep a few grams of sugar, under 10 g/L, which can hide flaws, and it notes that many grocery-store wines sold as dry have about 10 g/L.

Sparkling wines

Sparkling wine gets a dose of sugar (the dosage) just before it is corked, and the label word tells you how much. These are the Comité Champagne’s ranges for Champagne:

Label term	Sugar (g/L)
Brut Nature, Pas Dosé, Dosage Zéro	Under 3, no sugar added
Extra Brut	0 to 6
Brut	Under 12
Extra Dry	12 to 17
Sec	17 to 32
Demi-Sec	32 to 50
Doux	Over 50

So on a sparkling wine, “Extra Dry” and “Dry” are sweeter than Brut. For the lowest sugar, our pick is Brut Nature or Extra Brut.

How to read the label

EU terms for still wine

For still wine, EU Regulation 2019/33 (Annex III, Part B) defines the sweetness words:

Term	Residual sugar
Dry	Up to 4 g/L, or up to 9 g/L if total acidity is no more than 2 g/L below the sugar
Medium dry	Above dry, up to 12 g/L, or up to 18 g/L if total acidity is no more than 10 g/L below the sugar
Medium (medium sweet)	Above medium dry, up to 45 g/L
Sweet	45 g/L or more

You’ll see these as sec, secco or seco on French, Italian and Spanish bottles.

German terms

German labels use the same limits. The German Wine Institute (Wines of Germany) lists:

Term	Meaning	Residual sugar
Trocken	Dry	Up to 4 g/L, or up to 9 g/L if sugar is no more than 2 g/L above acidity
Halbtrocken	Off-dry	Up to 12 g/L, or up to 18 g/L if sugar is no more than 10 g/L above acidity
Feinherb	Off-dry (unofficial)	Not regulated; usually between halbtrocken and sweet
Lieblich	Semi-sweet	Up to 45 g/L
Süß	Sweet	45 g/L and above

A German Kabinett or Spätlese without the word trocken is often lightly sweet. And the “trocken” in Trockenbeerenauslese refers to dried grapes, not a dry wine: it is one of the sweetest wines made.

US labels

Labels on regular wine (7% alcohol and up) don’t have to state sugar, and Wine Folly notes that alcoholic drinks aren’t required to carry a nutrition label. The exception is wine under 7% alcohol, which falls under FDA food labeling, including nutrition labeling where it applies, as our low alcohol wine guide explains. A few clues help:

1. Look for a dry term. Brut Nature, Extra Brut, trocken, sec, secco or seco all point to low sugar.
2. Watch the alcohol. A still white at 8% to 10% alcohol usually has sugar left over, because fermentation stopped early.
3. Be wary of “sweet”, “blush” and pink grape names. White Zinfandel and pink Moscato are made off-dry to sweet.
4. Find the tech sheet. Wine Folly says producers often publish technical information online, and learning to read those tech sheets tells you the sweetness level. Under about 4 g/L is dry by the EU standard.

Wines that are high in sugar

If you want low sugar, these are the bottles to skip. Port, Sauternes, Tokaji Aszú, ice wine and late-harvest wines are made to be sweet, and USDA’s dessert wine entry has about 8 grams of sugar in a small 3.5-ounce glass. Wine Folly estimates that mevushal wines such as Manischewitz contain around 170 g/L.

The short version

• Driest still wines: wines labeled dry, sec, secco, seco or trocken, and classic European dry whites and varietal reds.
• Driest sparkling wines: Brut Nature (under 3 g/L) and Extra Brut (0 to 6 g/L). Extra Dry is sweeter than Brut.
• A glass of dry red or white: about 0.9 to 1.4 grams of sugar in USDA data.
• When in doubt: check the producer’s tech sheet for residual sugar.

If you are trying a new dry style, start with a small bottle or a half bottle and check the tech sheet before buying a case.
