How to Make Fortified Wine: Port and Sherry Basics

Updated: February 2026 | Reading Time: 11 minutes

Fortified wine occupies a unique space in the world of wine—spirits-blended beverages that combine the complexity of wine with the warming presence of brandy. From the ruby richness of Port to the nutty complexity of Sherry, these are wines meant for contemplation, pairing with food, and long-term aging.

The good news: fortified wines are among the easiest styles to make at home. The fortification process (adding spirits to halt fermentation) is straightforward, and the result is stable, long-lived wine. In this guide, we'll explore the major styles and how to create them in your own home.

What Is Fortified Wine?

Fortified wine is wine that has had spirits (usually brandy) added to it. This serves several purposes:

• Stops fermentation: High alcohol kills yeast, preserving residual sugar
• Increases alcohol: Typically 15-22% ABV
• Adds complexity: The spirit contributes its own flavors
• Extends shelf life: Higher alcohol and no live yeast means stability

While originally developed to make wines stable for shipping (hence "Port" from Portugal's Douro Valley), fortified wines have evolved into beloved styles with their own traditions and characteristics.

Major Styles of Fortified Wine

Port (Portugal)

Sweet, fruity, and rich. Made primarily from Touriga Nacional and other Portuguese varieties.

• Ruby Port: Young, fruity, basic style
• Tawny Port: Aged in wood, nutty and complex
• Vintage Port: Premium, aged in bottle
• Late Bottled Vintage (LBV): Aged longer before release

Sherry (Spain)

Dry (usually) and complex, aged oxidatively under flor yeast.

• Manzanilla: Light, salty, fresh
• Fino: Dry, light, aged under flor
• Amontillado: Dry, nutty, more complex
• Oloroso: Rich, dry, dark
• Pedro Ximenez (PX): Extremely sweet, syrupy

Madeira (Portugal)

Heat-treated, oxidized, can be sweet or dry. Made from specific grape varieties.

Marsala (Italy)

Used primarily for cooking, but can be drunk as dessert wine.

Making Your Own Port-Style Wine

Let's focus on making a Ruby Port-style wine, the most accessible approach for home winemakers.

Step 1: Make Your Base Wine

Start with a red wine that's suitable for aging. Use bold, fruity varieties:

• Cabernet Sauvignon
• Zinfandel
• Touriga Nacional (if available)
• Blend of varieties

Follow your standard red winemaking process:

1. Crush and ferment with skin contact
2. Press when fermentation is near completion
3. Complete fermentation to dryness (or slightly sweet)
4. Age briefly (1-3 months) in neutral oak or stainless steel

Step 2: Prepare for Fortification

When to fortify:

• Ideally, when fermentation is nearly complete (just a few degrees Brix remaining)
• This preserves some sweetness while allowing some fermentation to finish
• The wine will be sweet, fruity, and ready for aging

Step 3: Fortify

Add brandy or neutral spirit to your wine:

1. Measure your wine volume accurately
2. Calculate the amount of spirit needed
3. For most Port-style wines: Add enough to reach 18-20% ABV
4. Add slowly, stirring gently
5. Taste and adjust
