Port and Sherry, two beloved fortified wines, hold a special place in the hearts of wine enthusiasts around the world. Both are known for their rich, complex flavors, and their history stretches back centuries. However, despite some superficial similarities, the two wines differ in significant ways—beginning with their production methods, the regions where they are made, and the grape varieties used.
In this article, we will explore whether port is like sherry, diving deep into their history, how they are made, and their unique characteristics. By the end of this comparison, you’ll have a clear understanding of what sets these two fascinating fortified wines apart, while also appreciating the similarities that might make you wonder if they are, in fact, more alike than they seem.
The Origins of Port and Sherry
The Birth of Port Wine
Port wine has its roots in the Douro Valley of northern Portugal. The wine’s origins trace back to the 17th century, a time when English merchants began seeking a solution to the harsh shipping conditions that often spoiled their wines. The British found that by fortifying the wine with brandy (a distilled form of alcohol), they could prevent the wine from spoiling during the long sea voyage. This practice led to the creation of what we now know as port.
Port was initially created to suit the taste preferences of English consumers, but over time, it became a wine that was appreciated globally. The town of Vila Nova de Gaia, located just across the river from Porto, became the center of port production and the home of numerous famous port houses.
The Birth of Sherry Wine
In contrast, Sherry has its origins in the southern Spanish region of Andalusia, specifically around the town of Jerez de la Frontera. Sherry’s history dates back to the Phoenician settlers who cultivated vineyards in the region, and it has evolved significantly over the centuries.
The distinctiveness of sherry lies in its aging process, which involves a unique method called the “solera system.” This technique, which has been refined over centuries, combines different ages of wine to create a blend that maintains consistency year after year. Like port, sherry was also developed to meet the needs of international markets, particularly the British, who began importing it in large quantities in the 18th century.
Production Methods – Fortification and Aging
The Process of Fortification in Port
One of the most significant factors that set port apart from other wines is its fortification process. Fortification refers to the addition of a distilled spirit (usually brandy) to the wine to increase its alcohol content and stop the fermentation process. This process allows port to retain its natural sweetness and develop the rich, full-bodied character that is so characteristic of the wine.
During the production of port, fermentation begins as usual. However, once the sugar levels in the wine reach a certain point, the winemaker adds brandy, which halts fermentation by killing the yeast. This results in a wine that has a higher alcohol content (typically around 19-22%) and retains much of its natural sweetness.
Port is then aged, often in oak casks, which imparts additional complexity and flavors. Some styles of port, such as Vintage Port, are aged for years in the bottle, while others, like Tawny Port, are aged for a long time in wooden casks to develop a smooth, nutty profile.
The Fortification and Aging Process in Sherry
Sherry, too, undergoes fortification, but the process differs from port. In sherry production, the wine is fermented to dryness before it is fortified with brandy. The purpose of this fortification is not to stop fermentation, but rather to boost the alcohol content to a level that is suitable for aging. As a result, sherry tends to be less sweet than port, although some styles of sherry, such as Cream Sherry, are sweetened after the aging process.
Sherry is aged using the solera system, a unique method of blending wines of different ages. In the solera system, older wines are mixed with younger wines in a series of barrels, creating a consistent and complex flavor profile over time. The aging process can take many years, and the wine is often exposed to the air during this time, resulting in a distinctive oxidative style that is a hallmark of sherry.
Key Styles of Port and Sherry
Styles of Port Wine
Port is known for its wide range of styles, each with its own distinct flavor profile. The most common styles of port include:
Ruby Port: This is the youngest style of port, aged for a relatively short period (typically 2-3 years) in large oak casks or stainless steel tanks. It is deep red in color and has a fruity, youthful flavor.
Tawny Port: Tawny port is aged for a longer period, typically in smaller oak barrels, which allows for greater oxidation. This results in a wine with a lighter, amber color and a complex flavor profile that includes nutty, caramel, and dried fruit notes.
Vintage Port: This is the most prestigious style of port, made from the best grapes in a single year. It is aged in the bottle for many years, allowing it to develop a rich, complex flavor profile with intense fruit flavors and the potential for long-term aging.
Late Bottled Vintage (LBV) Port: This style of port is made from grapes from a single vintage but is aged for longer in the cask before being bottled. It is often more accessible than vintage port, offering a similar depth of flavor with less aging potential.
White Port: Made from white grapes, white port is often lighter and drier than red port, although it can also be sweetened in certain styles.
Styles of Sherry Wine
Sherry is also made in a wide range of styles, and the variations can be quite striking. The main styles of sherry include:
Fino: Fino sherry is the driest and lightest style, aged under a layer of yeast called “flor,” which prevents oxidation. It is pale in color, with a crisp, clean flavor profile that includes hints of almonds and brine.
Manzanilla: A substyle of fino sherry, manzanilla is produced in the coastal town of Sanlúcar de Barrameda. It has a similar profile to fino but with a more pronounced salty, maritime influence due to the proximity to the sea.
Amontillado: Amontillado starts as fino but undergoes oxidative aging after the flor yeast layer dies. This gives it a deeper, richer flavor with nutty and caramel notes, making it an intermediate style between fino and oloroso.
Oloroso: Oloroso sherry is aged without the protection of flor, which allows for more exposure to oxygen. As a result, it develops a rich, full-bodied flavor with notes of dried fruit, nuts, and spices. Oloroso is usually dry but can also be sweetened to create styles like Cream Sherry.
Palo Cortado: This rare style begins life as a fino but, for unknown reasons, the flor layer breaks down. The wine then undergoes oxidative aging, creating a blend of the finesse of fino and the richness of oloroso.
Cream Sherry: This is a sweetened version of oloroso or amontillado, and it is often enjoyed as a dessert wine. It has a smooth, velvety texture with flavors of raisins, toffee, and nuts.
Key Differences Between Port and Sherry
Differences in Alcohol Content
One of the most immediate differences between port and sherry is their alcohol content. Port wines typically have an alcohol content of around 19-22%, which is higher than most wines due to the fortification process. Sherry, on the other hand, has a slightly higher range of alcohol content, usually around 17-20%, depending on the style.
Differences in Sweetness
Port tends to be sweeter than sherry, especially in its ruby and tawny styles. The fortification process in port halts fermentation before all the sugar is converted into alcohol, which results in a wine with residual sugar. Sherry, on the other hand, is usually fermented to dryness before it is fortified, making it a drier wine overall, with the exception of certain styles like Cream Sherry.
Differences in Aging and Oxidation
While both port and sherry are aged to develop their unique characteristics, the aging processes are quite different. Port is usually aged in large oak barrels or stainless steel tanks, which limit the amount of oxygen exposure. This results in a wine that retains its rich fruit flavors.
Sherry, particularly in the case of styles like fino and amontillado, is aged in barrels where the wine is exposed to more oxygen, resulting in a distinctive oxidative character. This leads to a wine that is more complex and nutty, with flavors that evolve over time in a way that is unique to sherry.
Conclusion
While port and sherry share some similarities, such as their fortification process and their long histories as fortified wines, the differences between them are far more pronounced. The regions where they are made, the grape varieties used, their aging processes, and their flavor profiles all distinguish these two wines.
Port is generally sweeter and fruitier, while sherry offers a more complex, often drier, and sometimes oxidized character. Their differences are enough to make each wine distinct in its own right, but there are also enough similarities to make them both incredibly versatile and beloved among wine lovers.
In the end, whether port and sherry are “like” one another depends on your perspective. If you’re looking for fortified wines with depth and complexity, both offer exceptional experiences, but they do so in very different ways.
