To read a wine label, look for five things: who made it, the grape or the place, the vintage, the alcohol and any quality terms. On an American bottle, the grape name, the place and the year each come with a legal percentage behind them, set by the federal Alcohol and Tobacco Tax and Trade Bureau (TTB). European labels work differently: they usually lead with the place, and the place’s rules tell you the grapes. This guide walks through both, so you can tell what is a legal promise and what is just marketing.

What a US wine label must show

The TTB’s “Anatomy of a Wine Label” lists the information every wine sold in the US has to carry. Some of it must be on the brand label, the rest can be on any label, including the back.

ItemRequired?Where
Brand nameAlwaysBrand label
Class or type (e.g. “Red Wine”, “Cabernet Sauvignon”)AlwaysBrand label
Appellation of origin (the place)When the label shows a grape, a vintage or “estate bottled”, among other casesBrand label, next to the class or type
Alcohol contentAlways for wines over 14%; optional at 7% to 14% if the label says “table wine” or “light wine”Any label
Net contents (e.g. 750 ml)AlwaysAny label
Name and address of the bottler or importerAlwaysAny label
Sulfite declarationAt 10 parts per million or moreAny label
Health warning statementAlwaysAny label

Everything else, such as a fanciful wine name, pictures, tasting notes and website links, is optional. The TTB says a fanciful name can’t replace the class or type, and that if no other brand name appears, the bottler’s or importer’s name counts as the brand.

The grape: the 75% rule

A wine can be named after a single grape, such as “Pinot Noir”, only if at least 75% of the wine comes from that grape, under federal rule 27 CFR 4.23. All of that 75% must have been grown in the place named on the label, and a grape name is only allowed if the label also shows an appellation. The rule drops to 51% for Vitis labrusca grapes such as Concord, and for grapes the TTB finds too strongly flavored at 75%, if the label says “contains not less than 51 percent” of the grape.

A label can list two or more grapes, for example “Cabernet Sauvignon–Merlot”, only if every grape in the wine is listed and the percentage of each is shown, within 2%. So a bottle of “Chardonnay” can legally contain up to 25% of something else, and a wine with no grape at 75% is sold under a brand name or simply as “red wine” or “white wine”. Our guide to red blend wine explains how blends use this rule.

The place: appellations and AVAs

The appellation of origin is where the grapes were grown. The TTB sets different minimums depending on how specific the place is:

Label saysMinimum from that place
“American” or “United States”75% US-grown, and fully finished in the US
A state, such as “California”75% from that state, finished in that state or an adjacent one
A county, such as “Sonoma County”75% from that county, finished in that state; the word “County” must appear
Several states or several counties100% from the listed areas, with each one’s percentage shown (within 2%)
An AVA, such as “Napa Valley” or “Willamette Valley”85% from that viticultural area

An AVA (American Viticultural Area) is a grape-growing region with recognized boundaries. The TTB adds that an AVA wine must be finished in the state or states where the AVA lies, and that wine named after any place must also follow that place’s own laws. Imports work much the same way: at least 75% from a named country and 85% from an approved foreign viticultural area, and the wine must also meet the producing country’s own laws.

Tip: The more specific the place, the stricter the rule. Wine Folly makes the same point from the buyer’s side: a broad region on the label usually signals an everyday wine, while a single vineyard usually means a more ambitious, pricier one.

The vintage: 85% or 95%

The vintage is the year the grapes were harvested. Under 27 CFR 4.27:

  • with an AVA on the label, at least 95% of the wine must come from grapes harvested that year;
  • with any other appellation (country, state, county), at least 85%;
  • a vintage date always requires an appellation on the label.

Imported wine can carry a vintage only if its country of origin regulates vintage dates and the wine could carry that year if sold at home. A wine without a year is non-vintage (NV): Wine Folly explains that it is blended from several harvests to keep the flavor consistent.

Alcohol content

Wines over 14% must show a number; between 7% and 14% the winery can write “table wine” or “light wine” instead. The TTB doesn’t allow the abbreviation “ABV” on the label, which is why you see wording such as “alc. by vol.” instead. The number isn’t exact either: the rules allow a tolerance. Our guide to wine alcohol content explains the tolerances and typical strengths by style.

Wine Folly offers one rule of thumb: a higher alcohol figure often points to riper grapes and a richer, more fruit-forward wine, though it calls this a generalization with exceptions.

Sulfites and the government warning

  • “Contains sulfites” is required when a wine has 10 parts per million or more of sulfur dioxide, measured as total SO2. Wine Folly notes that grapes naturally carry some sulfur.
  • The health warning begins “GOVERNMENT WARNING”. The TTB says the same statement is required on all alcoholic drinks with 0.5% alcohol or more, with exactly the official wording, punctuation and capitalization, set apart from the other text on the label.

Estate bottled, Reserve and other terms

TermLegal meaning in the US
Estate bottledPer the TTB: 100% of the wine came from grapes grown on land the winery owns or controls, the winery and vineyards are in the AVA named on the label, and the grapes were crushed, fermented and bottled at the winery. It requires an AVA appellation.
ReserveNone. Wine Folly says some small producers use it for their best barrels; treat it with caution.
Old VinesNone. Wine Folly says vines sold as “old” can be anywhere from 15 to 115 years old.
Proprietary or fanciful nameOptional, but can’t replace the class or type.

In our view, “estate bottled” is the most useful of these words, because it is the only one with a strict legal definition behind it.

Reading European labels

Wine Folly sums up the main difference: many European labels are appellation-based. They name the place, and the place’s rules decide the grapes, so a bottle of Chablis, for example, doesn’t need to say it is Chardonnay. Here are the essentials for four countries.

France

The appellation is the main clue: Bordeaux, Sancerre, Chablis, Châteauneuf-du-Pape. Learn which grapes each place uses and you can read most French labels. Wine Folly lists “Mis en bouteille au château” as the French equivalent of estate bottled. Our French wine guide explains the AOC, IGP and Vin de France tiers and the main label terms.

Italy

Italian labels show a quality level next to the place name. According to Italian Wine Central:

LevelMeaningNumber
DOCGDenominazione di Origine Controllata e Garantita, the highest level79
DOCDenominazione di Origine Controllata, the second level332
IGT / IGPIndicazione Geografica Tipica / Protetta, larger areas with looser rules111
VinoWine that meets neither DOP nor IGP rulesn/a

DOCG and DOC together form the EU’s protected designation of origin (DOP). Our Italian wine guide covers terms such as Classico and Riserva.

Spain

Spanish labels often add an ageing category. For red Rioja, the DOCa Rioja regulator sets these minimums:

TermRed Rioja
CrianzaAt least 2 years in total, at least 1 in oak barrels
ReservaAt least 3 years, including at least 1 in oak and 6 months in bottle
Gran ReservaAt least 5 years, with 2 in oak and 2 in bottle

Rioja also allows place terms: Vino de Zona (Rioja Alta, Rioja Alavesa or Rioja Oriental), Vino de Municipio (one of 144 villages) and Viñedo Singular, a single-vineyard category introduced in 2017. Other Spanish regions set their own ageing minimums.

Germany

German labels name the producer (often Weingut or Schloss), the grape, the village and vineyard and one of 13 wine regions, such as Mosel or Rheingau. German Wines USA, a site published under the Wines of Germany logo, lists four quality categories, from Deutscher Wein and Landwein to Qualitätswein and Prädikatswein, and says most German wine in the US is one of the last two.

Prädikatswein adds one of six ripeness levels: Kabinett, Spätlese, Auslese, Beerenauslese and Trockenbeerenauslese, in rising order of ripeness, plus Eiswein, made from grapes picked and pressed while frozen. These describe how ripe the grapes were, not necessarily how sweet the wine is, so look for the dryness words:

TermMeaning (German Wines USA)
TrockenDry; never more than 9 g of residual sugar per liter
HalbtrockenOff-dry, often tasting dry thanks to high acidity
FeinherbAn unofficial term for off-dry, similar to halbtrocken

If none appears, German Wines USA suggests checking the alcohol: a lower figure generally means more residual sugar.

Use the label to pick a better bottle

A label tells you what the wine legally is, not how good it is. For that, in our view, the best next step is a published critic score for the exact vintage. Our guide to how wine ratings work explains the 100-point scale, and our value picks follow how we rate wine: a critic score for a named vintage plus a US price checked at two or more stores.

Tip: We’d read a label in this order: place, grape, vintage, producer, alcohol. The first three tell you the style; the producer tells you whom to trust next time.

Frequently asked questions

What percentage of a wine has to be the grape on the label?

In the US, at least 75%. Under federal rule 27 CFR 4.23, a wine labeled "Merlot" must get at least 75% of its volume from Merlot grapes, all grown in the place named on the label.

What does an AVA on a wine label mean?

An AVA (American Viticultural Area) is a federally recognized grape-growing region such as Napa Valley. At least 85% of the wine must come from grapes grown there, according to the TTB.

How accurate is the vintage on a wine label?

For a wine labeled with an AVA, at least 95% must come from grapes harvested in that year; with a state, county or country appellation, at least 85%. A vintage date always requires an appellation on the label.

What does "estate bottled" mean?

The TTB says all of the wine came from grapes grown on land the winery owns or controls, inside the AVA named on the label, and that the winery crushed, fermented and bottled it on its own premises.

Does "Reserve" mean anything on a US wine label?

Not legally. Wine Folly notes that "Reserve" has no official meaning in the US, and "Old Vines" has no legal minimum vine age. Some producers use them for their best wines, others for marketing.
