Character.
- Grape spirit added during or after fermentation
- Higher alcohol content (15-22%)
- Spirit added during fermentation leaves the wine sweet; after fermentation, dry
- Ranges from bone-dry aperitifs to intensely sweet dessert styles
- Nutty, oxidative flavors from long cask aging
- Keeps far longer after opening than table wine, from days to months by style
What is fortified wine?
Fortified wine is wine with grape spirit added to it. The spirit is usually a fairly neutral brandy, and it lifts the alcohol from the 11% to 14% of ordinary wine up to somewhere between 15% and 22%.
The practice began as insurance. Before refrigeration and stainless steel, wine shipped across warm oceans arrived spoiled. Alcohol is a preservative, so merchants trading between Portugal, Spain, and northern Europe learned to stabilize their barrels with spirit. What started as a shipping problem turned into six of the most distinctive wine styles in the world.
Fortified wine is not the same as dessert wine, though the two overlap. Plenty of dessert wines are unfortified, and plenty of fortified wines are bone-dry.
When the spirit goes in decides everything
This single decision determines whether the finished wine is sweet or dry. Fermentation is yeast eating sugar and producing alcohol. Yeast cannot survive much above 15% or 16% alcohol. So a winemaker who adds spirit mid-fermentation kills the yeast while sugar is still in the tank, and that sugar stays in the bottle.
| Timing | What happens | Result | Classic examples |
|---|---|---|---|
| During fermentation | Spirit kills the yeast early | Sweet, grapey, fruit-forward | Port, Vins Doux Naturels |
| After fermentation | All sugar has already converted | Dry, savory, nutty | Fino and Oloroso Sherry |
| After, then sweetened | Dry base wine blended with sweet wine | Sweet but savory underneath | Cream Sherry, some Madeira |
This is why Sherry confuses people: a bone-dry Fino and a syrupy Pedro Ximénez come from the same town by different routes.
Port
From the terraced Douro Valley in northern Portugal, made from indigenous grapes including Touriga Nacional, Touriga Franca, and Tinta Roriz. Spirit goes in during fermentation, so all Port is sweet, and most sits between 19% and 22% alcohol.
| Style | Aging | Tastes like | Price band |
|---|---|---|---|
| Ruby | Short, in tank or large vats | Bright blackberry, plum, simple | $12 to $18 |
| Reserve Ruby | A few years, blended | Richer dark fruit, some depth | $18 to $28 |
| Late Bottled Vintage | Four to six years in cask | Plum, chocolate, softened tannin | $20 to $35 |
| Vintage | Two years in cask, decades in bottle | Concentrated, structured, ageworthy | $50 and up |
| Tawny (10, 20, 30, 40 year) | Long, in small casks | Caramel, walnut, dried fig, orange peel | $25 to $150 |
| White Port | Varies | Citrus, almond, honeyed | $12 to $20 |
Two Ports matter most for beginners: a ten-year Tawny, the most versatile bottle in the category, and a Late Bottled Vintage, which gives most of the Vintage Port experience for far less. Our Port wine guide goes deeper.
Sherry
From Jerez in Andalusia, southern Spain, made mostly from the Palomino grape and aged in a solera, a stack of barrels where older wine is topped up with younger wine year after year. Spirit is added after fermentation, so Sherry starts dry. It is the most misunderstood wine in the world and one of the cheapest great ones.
| Style | How it ages | Tastes like | Sweetness |
|---|---|---|---|
| Manzanilla | Under flor yeast, in coastal Sanlúcar | Sea salt, green apple, almond | Bone-dry |
| Fino | Under flor yeast, in Jerez | Almond, bread dough, saline | Bone-dry |
| Amontillado | Under flor, then exposed to air | Hazelnut, dried herbs, tobacco | Dry |
| Palo Cortado | Flor fails, then oxidative | Between Amontillado and Oloroso | Dry |
| Oloroso | Fully oxidative, no flor | Walnut, leather, dried orange | Dry |
| Cream | Oloroso sweetened after aging | Toffee, raisin, walnut | Sweet |
| Pedro Ximénez | Sun-dried grapes, oxidative | Liquid raisin, molasses, coffee | Intensely sweet |
Flor is the crucial concept. It is a living film of yeast that grows on the surface of the wine in barrel, protects it from air, and gives Fino and Manzanilla their bracing, salty character. When it dies off, air gets in, the wine darkens, and you get Amontillado. Full detail in the Sherry wine guide, and the Port versus Sherry comparison sets the two side by side.
Madeira
From the Portuguese island of Madeira, and unique because it is deliberately damaged. The wine is heated, either slowly in warm lofts (the canteiro method, used for the best bottles) or faster in heated tanks (estufagem), and exposed to oxygen. Both processes would ruin any other wine. Here they create caramel, toasted nut, and burnt orange flavors, plus near-immortality.
| Style | Grape | Sweetness | Tastes like |
|---|---|---|---|
| Sercial | Sercial | Dry | Lemon, almond, saline, high acid |
| Verdelho | Verdelho | Medium dry | Smoke, dried apricot, orange peel |
| Bual | Boal | Medium sweet | Raisin, coffee, dark caramel |
| Malmsey | Malvasia | Sweet | Toffee, fig, dark chocolate |
| Rainwater | Usually Tinta Negra | Off-dry, lighter | Soft nuts and citrus, gentle |
Madeira’s acidity is extreme, which is why the sweetest examples never taste cloying, and why bottles from the nineteenth century are still drinkable today. Read the Madeira wine guide for the full story.
Marsala
From western Sicily, created by English merchants in the late eighteenth century as a rival to Madeira. Most people only meet it in a pan with chicken, which is a shame, because the aged versions are serious wine.
| Grade | Minimum aging | Notes |
|---|---|---|
| Fine | About one year | The cooking grade, sold cheaply |
| Superiore | Two years | Drinkable, nutty, mid-weight |
| Superiore Riserva | Four years | Concentrated, more complex |
| Vergine or Soleras | Five years | Dry, unsweetened, seriously good |
| Vergine Stravecchio | Ten years | The benchmark, rare outside Italy |
Marsala is also classified by color (Oro and Ambra from white grapes, Rubino from red) and by sweetness (Secco, Semisecco, Dolce). If you have only cooked with it, buy a Vergine and drink it alongside hard cheese.
Vermouth
Vermouth is fortified wine that has also been aromatized, infused with botanicals, always including wormwood, from which it takes its name. It usually sits between 15% and 18% alcohol, and under European rules the base must be mostly wine.
| Style | Origin | Tastes like | Use |
|---|---|---|---|
| Dry (French style) | Marseille and Chambéry | Herbal, saline, bitter, pale | Martini, drink chilled |
| Sweet red (Italian style) | Turin | Vanilla, orange, spice, caramel | Negroni, drink over ice |
| Bianco | Italy | Sweet, floral, lighter | Aperitif with soda |
| Rosé | Italy and France | Berry, citrus, bittersweet | Aperitif with tonic |
The single most useful fact about vermouth is that it is wine, not spirit. Once opened it belongs in the refrigerator and it deteriorates in weeks. A dusty bottle on a back shelf is the reason many people think they dislike Martinis.
Vins Doux Naturels
The French answer to Port, mostly from Roussillon in the far south and from the southern Rhône. Fermentation is stopped with spirit, a process the French call mutage, which leaves natural sweetness. The name means naturally sweet wine, which is slightly misleading given the added alcohol.
| Wine | Grape | Style | Tastes like |
|---|---|---|---|
| Muscat de Beaumes-de-Venise | Muscat | Golden, aromatic | Peach, orange blossom, honey |
| Muscat de Rivesaltes | Muscat | Golden, aromatic | Grape, apricot, floral lift |
| Banyuls | Grenache | Red, ageworthy | Cherry, cocoa, dried fig |
| Maury | Grenache | Red, structured | Blackberry, coffee, spice |
| Rivesaltes Ambré or Tuilé | Grenache | Oxidative, aged | Walnut, toffee, dried orange |
Banyuls is the classic partner for dark chocolate, one of the few genuinely reliable dessert pairings in wine. Australia’s Rutherglen Muscat works on similar principles and is worth seeking out.
Serving temperature
| Style | Serve at | Glass |
|---|---|---|
| Fino, Manzanilla, dry vermouth | 45 to 48°F | White wine glass, poured fresh |
| White Port, Muscat VDN | 46 to 50°F | Small white wine glass |
| Amontillado, Palo Cortado, Sercial | 54 to 57°F | Copita or small tulip |
| Tawny Port, Oloroso, sweet Madeira | 55 to 60°F | Small tulip glass |
| Ruby, LBV, Vintage Port, Banyuls | 60 to 65°F | Small wine glass |
Two rules cover most of it: chill the pale dry styles like white wine, and pour small measures. The serving temperature chart has the wider picture.
How long it lasts after opening
This is the question people actually search for, and it varies more than in any other category. The rule of thumb: the more oxygen a wine has already seen, the less an open bottle can hurt it.
| Style | Keeps for | Store it |
|---|---|---|
| Fino, Manzanilla | 3 to 5 days | Refrigerated, treat as white wine |
| Dry vermouth | 3 to 4 weeks | Refrigerated, always |
| Sweet vermouth | 1 to 3 months | Refrigerated |
| Vintage Port | 2 to 3 days | Cool and dark, recork tightly |
| Ruby and LBV Port | 2 to 3 weeks | Cool and dark |
| Amontillado, Palo Cortado | 2 to 3 weeks | Cool and dark |
| Oloroso, Tawny Port | 1 to 2 months | Cool and dark |
| Cream Sherry, Pedro Ximénez | 2 to 3 months | Cool and dark |
| Madeira, Marsala Vergine | 6 months or more | Anywhere sensible |
Food pairing
Fortified wine is the most food-flexible category in wine, because it spans bone-dry aperitifs and syrups thick enough to pour over ice cream.
Before the meal: Fino or Manzanilla with olives, salted almonds, jamón, or fried fish. Dry vermouth with citrus and a bowl of nuts.
During the meal: Amontillado with mushroom dishes, consommé, or roast chicken. Oloroso with red meat, game, or oxtail. Dry Sercial Madeira with soup, which sounds odd and works beautifully.
With cheese: Tawny Port with hard aged cheese. Ruby and LBV Port with Stilton and blue cheeses, the most famous pairing in the category. Oloroso with Manchego.
With dessert: Pedro Ximénez poured directly over vanilla ice cream. Banyuls with dark chocolate. Malmsey Madeira with coffee cake. Muscat de Beaumes-de-Venise with fruit tarts.
The governing rule is that the wine must be at least as sweet as the plate. A dry fortified wine next to a sweet dessert tastes thin and sour.
Where to start
Buy a ten-year Tawny Port and a bottle of Fino Sherry on the same trip. They cost about the same, sit at opposite ends of the category, and between them explain the whole idea: one sweet and nutty from slow oxidation, the other dry and salty from years under living yeast.
Use Sommo to scan any fortified bottle you come across. The app identifies the style, decodes the label, and tells you what to serve it with and how long it keeps once opened.
