Fermentation
Generally divided into two phases: tumultuous and slow
Tumultuous fermentation
Between 23 and 25 celcius to allow the yeast to develop, transforming all sugar to alcohol
Some sherry firms still use oak casks (traditional) to achieve certain characteristics in the wine
Slow fermentation
After approx. 7 days, hardly any sugar remains and the slow fermentation begins
Lasts several weeks for the remaining sugar to transform into alcohol without refrigeration
Base wine
Once the lees have been separated
Completely dry white wine consumed as is in the Jerez region
Pale, delicate, slightly fruity and low acidity
During the decanting process after the lees have been separated, a film of yeast known as flor forms over the surface of the wine. A type of cream
Flor
Unique characteristic of sherry
A creamy layer of yeast formed during the development of sherry
A yeast that continues to grow when there is no fermentable sugar left, surviving instead on part of the alcohol and other components in the wine
Completely covers the exposed surface of the wine, protecting it from oxidation
Fortification
Originally done to stabilise the wine during long voyages
Finos and Manzanillas fortified until they reach an ABV of 15%
Olorossos fortified until they reach an ABV of at least 17%
Purpose of fortification
Provides alcoholic strength enough to sustain the yeast that forms the flor, while creating an intolerable environment for other microorganisms
Finos and Manzanillas: Biological aging
Flor covers the surface, preventing unwanted bacteria to interfere with the aging process
Prevents oxidation while the wine undergoes changes to its composition
Interaction of the yeast with the wine alters the taste of the wine
Olorossos: Oxidative aging
The ABV of these wines is too high even for the yeast to develop
Leaves the wine exposed to the air, allowing a slow process of oxidation
The wine gradually darkens in colour and flavours intensify
Minimum legal aging duration
2 years, though many are aged for longer to achieve the desired distinct qualities
Solera system
Used for oxidative aging
Sherry is aged in American oak wood, a traditional component since trading with the Americas
