Sandeman Port 2

Port wine is a fortified wine from the Douro Valley in the northern provinces of Portugal. It is often served as a dessert wine due to its rich and sweet characteristics. The production of Port wine involves the addition of grape spirit, or brandy, to halt the fermentation process and retain a higher sugar content in the wine. This process also increases the alcohol content. The grapes used in the production of Port wine are primarily grown in the Douro Valley, a region characterized by its unique microclimate and terroir. This article lists the grape varieties commonly used in the production of Port wine, highlighting their importance in the creation of this iconic beverage.

Red Grape Varieties

The majority of Port wine is made from red grapes, which contribute to the wine's deep color and complex flavors. Some of the most important red grape varieties include:

• Touriga Nacional: Considered the finest grape variety for the production of Port wine, Touriga Nacional contributes intense floral aromas, high tannins, and concentrated flavors to the wine. It is also used in the production of high-quality dry red wines in Portugal.

• Touriga Franca: This grape variety is known for its fragrant aroma and is often blended with Touriga Nacional to produce Port wine. It adds elegance and structure to the blend.

• Tinta Roriz (also known as Tempranillo in Spain): Tinta Roriz is valued for its ability to add body and color to Port wine. It also contributes flavors of dark berries and spice.

• Tinta Barroca: Tinta Barroca is appreciated for its high sugar content and its ability to produce smooth, well-balanced wines. It is often used in blends to add sweetness and volume.

• Tinta Cão: This grape variety is known for its acidity and aromatic complexity, adding freshness and longevity to Port wine.

White Grape Varieties

Although less common than their red counterparts, white grapes are also used in the production of some styles of Port wine, particularly White Port. Important white grape varieties include:

• Malvasia Fina: A key white grape variety used in the production of White Port, Malvasia Fina contributes floral aromas and a smooth texture to the wine.

• Rabigato: Rabigato is valued for its acidity and freshness, making it an important component in the production of White Port.

• Codega: Also known as Codega do Larinho, this grape variety is used in White Port production for its aromatic qualities and ability to add complexity to the wine.

• Viosinho: Viosinho is appreciated for its ability to retain high levels of acidity, even in the hot Douro Valley, contributing to the freshness and balance of White Port.

Production and Aging

The production of Port wine involves the careful selection and blending of various grape varieties to achieve the desired style and flavor profile. After fermentation is halted by the addition of grape spirit, Port wine is aged in barrels or stainless steel tanks, depending on the style. The aging process can vary from a few years for basic Ruby Ports to several decades for Vintage Ports.

Conclusion

The grapes used in the production of Port wine are crucial to its unique flavor profile and character. Each grape variety contributes its own set of characteristics, from floral aromas and high tannins to sweetness and acidity, creating the complex and highly esteemed fortified wine known as Port.
