Is younger and fruity, with an average ageing time of one year. The typical aromas of distilled wine combine with some notes of the Sherries that were once aged in the casks. It is Straw-colored due to its short period of ageing, though some can acquire mahogany hues if they are aged in casks that once held Oloroso or Pedro Ximenez.

Is aged for three years on average. It is darker in color and the aromas are those of the wine spirit, with overlying reminiscences of the ageing process.

Is generally aged for ten years. With intense shades of mahogany colors and less pungent aromas dominated by hints of noble woods.

Distillation of the wines - 95% is made with Airen and Palomino grapes - takes place in copper stills called alquitaras. The wines are distilled without their corresponding lees and through simple distillation. The upper and lower layers are separated and only the centre part of the wine spirit is used. .
The casks used to age Jerez brandy, known in the Jerez D.O. area as butts, are all made of American oak wood and have a capacity of 250-600 liters.

The regulations dictate that they must have held some type of sherry for at least three years. These casks contribute significantly to the subtle differences found in Jerez brandies, depending on what type of cask is used. Thus, casks that have held dry Fino sherry yield paler brandies than those that have held Amontillado or Oloroso sherry. Jerez brandies that have been aged in casks that held Pedro Ximenez produce darker, smoother brandy.

The casks are set one atop another. The level of casks closest to the ground is called the Solera, from the Spanish word for floor or ground. Some brandy, generally less than 1/4 of the cask`s content, taken from each cask in the Solera and combined with brandy taken from other Soleras and then bottled. The empty space left in the casks of the Solera are replenished (they use the term sprinkled) with brandy from the next level up (called the 1st Criadera), which is in turn filled from the next Criadera, and so on. The top Criadera is filled with wine spirit. This system of ageing gives Jerez brandy a great deal of homogeneity and ensures sustained quality over time.
