Gin is really nothing more than a special case of a flavoured vodka, the flavouring agent in this case being mainly juniper berries but also small amounts of other botanicals such as orris root, cardamom, coriander. Different distillers use different recipes, which accounts for the slightly different taste of different brands. In a later section of the book a description will be given of a simple little piece of home-made equipment and the procedure involved in steam-distilling juniper berries and other herbs to produce a flavouring essence which can then be added to vodka to produce gin.
