What is Sherry wine and how is Spanish sherry aged?

Sherry is a Spanish traditional fortified wine aged in a solera system (explained below). It is famous worldwide, thanks to the Dukes of Medina Sidonia, who attracted English merchants and encouraged foreign trade since the 15th Century.

Sherry is one of the most versatile wines in the worlds. These wines range from extremely dry (the majority of the Sherry) to one of the sweetest wines in the world. Sherry, Vino de Jerez in Spanish, is produced only in Cadiz, Spain. The wines that will be aged to become sherry can be produced in the “Marco de Jerez” area. This area includes Rota, Chipiona, Trebujena, Lebrija and Chiclana de la Frontera (as well as the sherry triangle of course). Wines from Montilla Moriles made with Pedro ximenez is also allowed to be used for Sherry. However, these wines can only age within the Sherry Triangle to be considered Sherry wine and have the D.O. Jerez-Sherry-Xeres.

The Sherry Triangle

The Sherry triangle is the only place allowed by the committee where sherry can be aged. It is formed by: Jerez de la Frontera, where the origin of the name Jerez/Sherry comes from, Sanlucar de Barrameda and El Puerto de Santa Maria. We  always like to make names in Spain short and easy to read…not.

Soils to grow grapes for Sherry wine

There are three soils used to grow grapes for the D.O., Sand, clay and Albariza soils. Why is Sherry wine produced in this small area in Spain? Here we find a soil called “Albariza” a basic soil produced by marine organisms’ carcasses and other material. The soil has a very white colour in summer and able to absorb large amounts of rain. This is necessary in an arid region, since the D.O.committee does not allow farmers and producers to water the vines.

However, while Palomino and Pedro Ximenez grapes grow well in this soil, some say that the Moscatel de alejandria prefers Sandy soil. Most of the Pedro Ximenez grapes come from Cordoba province, from the Montilla-Moriles region.

A layer of yeast, called “flor”, is created at the top of most sherries during the aging of the wine. The flor separates the base wine from the oxygen within the barrel. This is used for wines such as Fino, Manzanilla, Amontillado and, sometimes, the begining of Palo cortado.

Manzanilla wine

The region of Sanlucar de Barrameda, also adds complexity to the wine with its micro-climate. Fine salt and floral tasting notes are noted, producing a different type of wine, not sherry, that has its own D.O. called Manzanilla. Though when it ages and oxidises becomes amontillado, a type of Sherry. Thus, the rest of fortified wines produced in Sanlucar are types of Sherry wines.

Sanlucar is the only place where this type of wine is produced, due to its location near the sea at the end of Guadalquivir river. The local climate has higher humidity with moderate temperatures, which creates a thicker layer of Flor. This is the only thing that differenciates Manzanilla from Fino, which is produced in Jerez de la Frontera and El Puerto de Santa María.

Throughout the Sherry triangle the strong humid, cold wind of Poniente (winds from the west), helps to develop the flor. However, people here are careful with the wind from Levante (from the east), as it is a warm and dry wind! The weather, together with the type of soil found in this region, makes this area of Spain a unique and ideal place for Sherry production and ageing.

How Sherry wine is aged

Sherry wine is a fortified wine. This means that they add destilled alcohol (brandy) to the already fermented base wine. Only the sweet wines PX and Moscatel de Alejandria the destilled alcohol is added before to stop fermentation. Dry base wine is produced by using a single grape variety called “Palomino”. In contrast, the sweet base wine is produced by using Pedro Ximénez and/or Moscatel de Alejandría. This last one can be mostly found in Chipiona or Chiclana. There are also sherries where dry and sweet sherry wines are combined.

Sherry Solera System

Sherry is then aged in a solera system, where there are at least 3 criaderas (rows of barrels) on top of each other. The bottom one is called Solera. This process helps to create a similar wine in quality, year after year. In addition, the newer wine added feeds the flor with nutrients.

Every certain amount of time, the wine from the solera is bottled. The cask is then filled up by the wine in the row above (1st Criadera), and this one filled by the 2nd Criadera, and so on. Therefore, the newly produced wine is in the top row and the oldest is in the bottom. Sometimes there are so many criaderas, that they stack the group of criaderas side by side (most common in Sanlúcar de Barrameda). They fill up the top criadera with the bottom criadera of the next stack of criaderas to create a more complex system.

Adding Brandy to wine to produce Sherry

Up to a third of the Sherry is bottled from the bottom row. This top row, or last “criadera” will be filled by a new base wine mix. The mix is 50% brandy and 50% wine, so that the flor is not killed with 100% Brandy. Depending on what Sherry they are producing, they will add either 15% mixture for biological ageing or 17% for oxidative ageing.

A cool fact is that there is always sherry wine left at the solera, as it is not completely emptied. Therefore, in each bottle there will always be at least a very small fraction of the first ever batch! This means part of the sherry may be hundreds of years old.

Types of Spanish Sherry wine

Spanish Sherry is generally divided into different types, depending on the grape used, the amount of brandy used to start, the amount of biological ageing, if it is composed of different sherry wines, and the location where the base wine is aged.

Of course, within these types are more special sherries like the Very Old Rare Sherries (VORS).  VORS have to spend more than 30 years in the solera system. At Bodega Fundador, they dedicate a whole warehouse just to these. They use a special mold that helps keep the moisture and temperature steady.
