Reserva, Gran Reserva, Reservado: what each word is worth, country by country
“Reserva” on the label means the wine met a legal yardstick, and the yardstick changes at the border: in Spain it's time with oak; in Brazil, time and alcohol; in Argentina, time; in Chile and Portugal, alcohol. In some countries it's a strong word, with inspectors behind it; in others, it's the winery's cheapest line.
The short answer
Spain: strict law. Argentina: law, but only about time. Brazil: a law since 2018, and a loose one: time, minimum alcohol and a cap on sugar in the must. Portugal: law, but about alcohol and vintage. Chile: half a degree more alcohol. And “Reservado” is, by Brazilian law, the winery's young wine: it asks for nothing beyond 10% alcohol.
Spain: the only one with a real yardstick
Spanish law (today in Ley 6/2015, which inherited the yardstick of the 2003 Ley de la Viña y del Vino) sets, for reds: Crianza = 24 months of aging, 6 of them in barrel; Reserva = 36 months, 12 in barrel; Gran Reserva = 60 months, 18 in barrel. Whites and rosés have shorter terms. Each appellation (Rioja, Ribera del Duero) may demand more, never less. It's the most trustworthy “Reserva” in the world.
Argentina: minimum time, no barrel required
The INV's Digest, the single text with the rules for Argentine wine (Resolución 37/2025, Annex D, items 1.5.1 and 1.5.2, in force since 1 January 2026), rules: Reserva = a red with at least 12 months of aging (6 for white and rosé); Gran Reserva = 18 months for reds (12 for white and rosé), and it demands more grapes per liter (140 kg of grapes per 100 liters, against 135 for Reserva). Gran Reserva reds needed 24 months under the old Resolución C.11/2011; Resolución 20/2020 lowered it to 18, and the Digest kept it. No barrel required: the wine can age in the tank. It says age, not quality.
Portugal: vintage and half a degree
Under Portaria 26/2017 (republished in 2024), Reserva is wine with a stated harvest year, “outstanding organoleptic characteristics” and alcohol at least 0.5% above the legal minimum; Grande Reserva goes up to 1% above, with “very outstanding” characteristics. For still wine, neither one requires any aging time. Garrafeira is the strong word over there: a red with 30 months of aging, 12 of them in the bottle (12 and 6 for white and rosé). This applies to wine with a DO or IG, and each region's rulebook can set its own rules.
Chile: alcohol, not time
Decreto 464 says a Reserva needs at least 0.5 degrees of alcohol above the legal minimum (11.5°) and “may” go through wood; Gran Reserva, 1 degree more and wood required. Not a single month of aging demanded. A Chilean Reserva at 12° is within the law.
Brazil: there's been a law since 2018, and it's a loose one
IN 14/2018 from Brazil's Ministry of Agriculture (art. 30) created the yardstick for vinho fino (Brazil's “fine wine” category) made in the country, and it's optional: the winery uses the word if it wants to, and then it has to comply. What it asks for is a mix of time and alcohol: Reserva = alcohol of 11% or more (ordinary vinho fino can start at 8.6%) and 12 months of aging for reds (6 for white and rosé), wood optional, which means it can be in the tank; Gran Reserva = the same 11% and 18 months for reds (12 for white and rosé), with at least 6 months in wood of up to 600 liters (3 for whites and rosés). And there's a detail almost nobody mentions: the law caps the sugar added to the must to raise the alcohol (chaptalization): in a Reserva, only enough to gain 1 point; in a Gran Reserva, none. It says time and alcohol, not quality, and the bar is low: plenty of entry-level wine fits. It applies only to Brazilian wine; imports follow the rules of their own country. There are excellent Brazilian Reservas; it's the word that guarantees little. Look at the rest of the label (the 4 pieces of information that matter).
And “Reservado”?
In Brazil the law even defines it: “young wine ready for consumption”, with 10% alcohol or more (IN 14/2018, art. 30), which is the same as saying entry-level wine. In Chile the word appears in Decreto 464, but as a free mention: it requires no alcohol, wood or time. In other countries, not even that. It usually christens the winery's simplest wine with a pompous name. It can be good and cheap; it's just not “reserved” for anything at all.
