Gin is an unaged liquor made by distilling grains such as barley, corn or rye. Its bouquet comes from juniper berries, coriander, herbs and spices, usually added to the grain mash during distillation. The gin is stored in glass, earthenware or stainless steel containers, but does not mature in these. The storage time serves only to harmonize the product.
Someone once said that "A bar without gin is like an Italian kitchen without pasta". No other liquor provides for the creation of so many classic cocktails. Gin is in fact a liquor that is harmonious with almost anything.
Without gin the king of cocktails, the dry Martini, would not exist.
