Ica is the main area in Peru for distilling pisco, the national spirit.
Pisco is made in a similar way to some types of brandy, but the final product is clear instead of dark. The grape juice is first fermented until it becomes a young wine. This means pisco is actually made from wine, not from the leftovers of wine production. After the fermentation has taken place, it is distilled and then rested in an odourless, non-reactive container (no wood) for a minimum of three months until it can be bottled. Pisco production is very strictly regulated and each producer must follow these same rules.
Pisco is absolutely delicious, especially when you buy it from a great producer.
