Editing Brandy (section)

===Aging===
After distillation, the unaged brandy is placed into [[oak barrel]]s to mature. Usually, brandies with a natural golden or brown colour are aged in [[oak]] [[aging barrel|casks]] (single-barrel ageing). Some brandies, particularly those from Spain, are aged using the [[solera]] system, where the producer changes the barrel each year. After a period of ageing, which depends on the style, class and legal requirements, the mature brandy is mixed with distilled water to reduce alcohol concentration and bottled. Some brandies have caramel colour and sugar added to simulate the appearance of barrel ageing.<ref name=Oxford/>
