Fortified wine is a category of wine that has a higher alcohol content compared to regular wine. It is created by adding a distilled spirit, such as brandy, to the wine during the fermentation process. This not only increases the alcohol content but also creates a unique flavor profile and enhances the wine’s ability to age. In this article, we will explore the various styles and methods of fortified wine production.
Port-style fortified wines
One of the most well-known styles of fortified wine is Port. Produced primarily in the Douro Valley in Portugal, Port-style fortified wines are made from a blend of indigenous grape varieties, including Touriga Nacional, Touriga Franca, and Tinta Roriz. The process involves stopping the fermentation by adding brandy, leaving residual sugar in the wine and resulting in a sweet and rich flavor. Ports can be aged in large oak barrels or in bottles, allowing them to develop complex aromas and flavors over time.

Sherry-style fortified wines
Another popular style of fortified wine is Sherry. Produced in the Andalusia region of Spain, Sherry-style fortified wines are made primarily from Palomino grapes. The fermentation process is stopped by adding grape spirit, resulting in a dry wine. Sherry is then aged using a unique solera system, where younger wines are blended with older wines in a series of barrels. This aging process creates a wide range of styles, from light and bone-dry Fino to rich and sweet Pedro Ximénez.

Madeira-style fortified wines
Madeira-style fortified wines are produced on the Portuguese island of Madeira using four main grape varieties: Sercial, Verdelho, Bual, and Malvasia. The grapes are fermented and fortified, and then the wine undergoes a unique aging process called estufagem. During this process, the wine is gently heated and cooled over a period of several months or years, which oxidizes and caramelizes the wine, giving it a distinctive nutty and caramel flavor. Madeira-style fortified wines are known for their incredible longevity and ability to improve with age.

Fortified wine production methods
In addition to the specific styles mentioned above, there are common methods used in the production of fortified wines.
Fortification during fermentation
The most common method is to add the distilled spirit, such as brandy, to the wine during the fermentation process. This stops the fermentation by killing the yeast, resulting in a higher alcohol content and a sweeter flavor profile.

Fortification after fermentation
Another method is to ferment the wine completely and then add the distilled spirit afterwards. This allows the primary fermentation to finish, resulting in a dry wine. The added spirit boosts the alcohol content and adds complexity to the final product.
