The process of adding alcohol to wine, also known as fortification, is a centuries-old practice that has been refined over the years to create some of the world’s most renowned wines. Fortification involves adding a neutral grape spirit to the wine during or after fermentation, which increases the alcohol content and helps to preserve the wine. In this article, we will delve into the history, methods, and techniques used to add alcohol to wine, highlighting the key factors that influence the final product.
History of Fortification
The practice of fortifying wine dates back to the 16th century, when Portuguese merchants began adding brandy to their wines to prevent spoilage during long sea voyages. This technique allowed the wines to withstand the harsh conditions and arrive at their destination in good condition. Over time, fortification became an integral part of winemaking, particularly in the production of port, sherry, and vermouth.
Types of Fortification
There are two primary methods of fortification: partial fortification and complete fortification. Partial fortification involves adding a small amount of neutral grape spirit to the wine during fermentation, which helps to arrest the fermentation process and retain some of the natural sugars. Complete fortification, on the other hand, involves adding a larger amount of neutral grape spirit to the wine after fermentation, which increases the alcohol content and helps to preserve the wine.
Partial Fortification Techniques
Partial fortification is commonly used in the production of port and some types of sherry. The process involves adding a small amount of neutral grape spirit to the fermenting must, which helps to arrest the fermentation process and retain some of the natural sugars. The amount of spirit added and the timing of the addition can vary depending on the desired level of sweetness and the style of the wine.
Complete Fortification Techniques
Complete fortification is commonly used in the production of vermouth and some types of sherry. The process involves adding a larger amount of neutral grape spirit to the wine after fermentation, which increases the alcohol content and helps to preserve the wine. The amount of spirit added can vary depending on the desired level of alcohol and the style of the wine.
Methods of Adding Alcohol to Wine
There are several methods used to add alcohol to wine, including:
- Batch Fortification: This involves adding a neutral grape spirit to a batch of wine, which is then mixed and blended to achieve the desired level of alcohol.
- Continuous Fortification: This involves adding a neutral grape spirit to the wine during fermentation, which helps to arrest the fermentation process and retain some of the natural sugars.
Factors Influencing Fortification
Several factors can influence the fortification process, including the type of grape variety, climate and soil conditions, and winemaking techniques. The type of grape variety can affect the level of sugar and acid in the wine, which in turn can impact the amount of spirit needed to achieve the desired level of alcohol.
