Fortified Wine
Fortified wine is a wine to which distilled spirits (typically grape brandy) have been added during or after fermentation, increasing the alcohol content above that of standard table wine, including products such as Port, Sherry, Madeira, and Vermouth.
In Plain English
Fortified wine is wine that has been made stronger by adding distilled spirits like brandy. This practice originated centuries ago as a way to preserve wine during long sea voyages. The added spirits raise the alcohol content, typically to between 15% and 22% ABV, compared to 11-15% for regular table wine. The most famous fortified wines are Port (from Portugal), Sherry (from Spain), Madeira (from the Portuguese island), Marsala (from Sicily), and Vermouth. Some of these terms can be used by U.S. producers with geographic qualifiers, while others are treated as semi-generic designations under TTB rules.
Technical Detail
Fortified wines are classified under 27 CFR 4.21(a)(5) as dessert wine with alcohol content between 14% and 24% by volume. The addition of distilled spirits is regulated to ensure it occurs according to specific production methods. For tax purposes, dessert wines over 14% but not exceeding 21% are taxed at $1.57 per gallon, and those between 21% and 24% at $3.15 per gallon. Semi-generic terms like "Port," "Sherry," and "Vermouth" may be used by U.S. producers if accompanied by a geographic qualifier indicating the true place of origin (e.g., "American Port" or "California Sherry"). The EU has sought to restrict these semi-generic uses through trade negotiations.
Why It Matters
Fortified wines represent a niche but significant category in the TTB database, with distinct regulatory, tax, and labeling considerations. The category includes both traditional products and newer innovations like vermouth, which has seen a renaissance in the cocktail culture era. For compliance consultants, the rules around semi-generic geographic terms for fortified wines are a common area of client questions. For market analysts, fortified wine filing trends can indicate shifts in cocktail culture and consumer preferences for aperitif and digestif-style products.

Frequently Asked Questions
Can American wines be called Port or Sherry?
Under current TTB regulations, U.S. producers can use semi-generic terms like "Port" and "Sherry" if accompanied by the true origin (e.g., "California Port"). However, ongoing trade negotiations may further restrict these uses. Imported products labeled "Port" must come from Portugal's Douro region, and "Sherry" must come from Spain's Jerez region.
What is the alcohol content range for fortified wines?
Fortified wines typically range from 15% to 22% ABV. TTB regulations classify dessert wines between 14% and 24% ABV. The added spirits bring the alcohol above normal fermentation levels (which usually max out around 15-16%).
Is Vermouth a fortified wine?
Yes. Vermouth is classified as an aromatized wine, which is a type of fortified wine. It is made by adding spirits and botanical flavorings to a wine base. Both sweet and dry vermouths are fortified wines that require formula approval from the TTB.
