Unlike regular table wines, fortified wines can pack a punch. But how do you know if your wine’s fortified?

You can tell if a wine is fortified by reading the label. Wines with alcohol above 17% are often fortified. You may also see phrases like “fortified” or “contains added alcohol”. Finally, some wine styles are always fortified, including: Sherry, Port, Marsala, Madeira, and Vermouth. 

Don’t worry! You’ll always know if you’re walking out of a wine shop with a fortified wine. Here’s how to know what wine is fortified.

What Is Fortified Wine?

Fortified wines are wines made with grapes, just like regular unfortified wine, but the winemaker adds spirits during the winemaking process, fortifying the wine. 

Fortified wines can be dry or sweet.

Winemakers can add spirit during fermentation when there’s still grape juice left over. This will make your fortified wine sweet. Or, they can add the spirit after the wine is done with fermentation. This will make your fortified wine dry. 

Helpful Tip: Fortified wines are relatively uncommon for most average wine drinkers, so I put together this post that goes into more detail on the differences between fortified and unfortified wines.

Fortified wines have a long history in the winemaking world. Originally, fortified wines proved crucial to keeping wine fresh during long overseas voyages. Today, many regions carry on their own fortified winemaking traditions. These unique wines can be a delight to explore, but hard to find.

How to Tell If a Wine Is Fortified Step 1: Read the Label

Look for high alcohol on fortified wines above 15%, and many above 17% abv.

Check the wine label closely. All fortified wine labels have clues. Phrases like “fortified”, or “fortified with brandy”, or “contains added alcohol” tell you that the wine is fortified. 

The label will also tell you how much alcohol is in the wine you’re holding.

Fortified wines typically have much higher levels of alcohol than regular table wine – 15.5%-22% alcohol by volume, compared to 11%-15% alcohol by volume. 

How to Know What Wine Is Fortified Step 2: Special Wine Types

Knowing some wines are always fortified is helpful. Like Madeira wine!

Some types of wine are always fortified. These are the traditional wines made in a fortified style in regions with a history of fortified winemaking. Types of fortified wine include:

  • Port from Portugal
  • Sherry from Spain
  • Marsala from Sicily, Italy
  • Madeira from Portugal
  • Rutherglen Muscat from Australia
  • Vin Doux Naturel from France
  • Vermouth (infused fortified wines)

If you see any of these wine names on your bottle along with a higher alcohol level, it’s a fortified wine.

Helpful Wine Buying Tip: Traditional wine names, like Port or Sherry, are highly regulated and only wines made from these historic regions can carry those names on their bottles. You may come across fortified wines made outside of these regions and the tasting notes will read something like “Port-style” or “made in a traditional Sherry-style”. This is a clue that the wine’s fortified.

Look for specific types of fortified wine: Some types of wine are almost always fortified. For example, port wine, sherry, and Madeira are always fortified, while other wines such as vermouth, Marsala, and some red wines may also be fortified.

How to Tell If Your Wine Is Fortified Step 3: Look for Funny Bottle Shapes

Funny bottle shapes mean there’s something special about the wine.

Most traditional fortified wines have a traditional bottle shape. These aren’t the normal looking wine bottles that unfortified wines use. They may be tall and stout, short and stubby, or even tall and slender.

Check out these cute stubby stoppers. You see these all the time on fortified wines, but they’re uncommon for regular wines.

You may also notice that they have stoppers instead of corks, which is quite common for fortified wines.

How to Tell If your Wine Is Fortified Step 4: Flavor Profile

If you’re out tasting wine and unsure if the wine in your glass is fortified, then take a sip and consider the flavor profile. The most noticeable quality of a fortified wine is the alcohol burn. You’ll notice that it prickles your tongue and gums, then warms up your chest as you swallow. 

Fortified wine tasting profiles tend to have a viscous sensation on your tongue and lips thanks to their high alcohol content. They also tend to be fuller-bodied.

Some fortified wines go through a deliberate oxidation process that brings out unique flavors like:

  • Treacle
  • Orange marmalade
  • Almond
  • Walnut
  • Praline
  • Leather
  • Furniture varnish

These are uncommon tasting notes in regular table wine. 

How to Tell If Your Wine Is Fortified Step 5: Ask for Help!

All of the dessert wines on this wine list are fortified wines. But you can always ask your server!

If you’re out shopping for wine or are at a restaurant, ask your server if the wine’s fortified. Most fortified wines will be at the end of a wine list where it has your dessert wines, but not always.

It’s highly unlikely you’ll ever wander into a wine shop and accidentally walk out with a bottle of fortified wine.

Likewise, most fortified wines are in their own section at wine stores. You’re really going to need to look for fortified wines to find them.
