To know what Sherry wine is you have to understand what a fortified wine is. To transform a regular wine into a fortified wine grape spirits or Brandy is added to the fermenting juice to stop sugars at a certain point from converting to alcohol. Sherry is one of those wines where grape spirits is added to stop this process. After the Sherry achieves its proper alcohol levels it is tested for quality and separated into two types of Sherry: Fino and Oloroso. Each of these types of Sherry have further classifications.
Three grapes provide the background for all types of Sherry wine: Palomino grapes, Pedro Ximenez and Moscatel. The Palomino grape is the backbone for every Sherry. It provides the overall quality of the Sherry. Pedro Ximenez is a sweet grape variety used as a sweetening agent. And Moscatel, or Muscat d’Alexandria provides the light amber colors of Sherry. Once the grapes have fermented to the right levels the juice is tasted and separated according to its quality into two groups. The best of the wine is made into Fino Sherry. Everything else is made into Oloroso Sherry.
Fino Sherry being the best of the Sherry wines is made entirely from the Palomino grape. Yeasts in the fermentation process give the wine its flavors and aromas. It is allowed a supervised exposure to oxygen to encourage aging and as it is a long process Fino Sherry is the smoothest and least acidic Sherry available. Its taste reminds you of roasted almonds.
An almost subcategory of Fino Sherry is Manzanilla Sherry. The S. Beticus yeast, native to the Sanlcar de Barrameda region, imparts a salty nuttiness due to its proximity to the ocean air. Manzanillas are given open exposure to the air in order to achieve proper maturation. This exposure ranges from short periods to moderate time in the sun and imparts a light to medium gold color.
Amontillado is the last category of Fino Sherry. It moves even further away from being a Fino as it reaches maturity. It’s full open air exposure darkens it to an almost dark brown and because of its exposure to the sun it develops a rich maderized flavor of roasted hazelnut. Amontillados are sweetened with the juice of sundried Palomino grapes called vino dulce or by adding pure sugar called dolce de albimar.
Oloroso Sherries are types of Sherry made from juice deemed of lesser quality than those made into Fino Sherry. There is nothing wrong with the juice that goes into making Oloroso, it is typically made from pressed juice, whereas Fino Sherry is more free-run juice.
The direct exposure to the open air and sun speeds the process of maturing in Oloroso Sherries. As a result of this exposed aging the Oloroso tends to be a little more abrasive than its smooth Fino cousin. Darker colors, deeper aromas and a fuller body are what characteristics define a good Oloroso. The flavors are intense toasted pecan.
A rare style of Sherry is the Palo-Cortado. It has all the aromas of an Amontillado but doesn’t go through the same process of yeast contact. On the other hand its colors and flavors are similar to Oloroso Sherry. It can be categorized in the middle of Fino and Oloroso but because of its unstable nature it eventually falls into the Oloroso style.
