Gin can be divided into three different types based on its production, origin or composition: official types, geographical types and unofficial types.
The production of official varieties is regulated by law. Only if the producers adhere to these regulations, they are allowed to name the gin accordingly.
Gin varieties with a geographical background are a speciality. Here it is not the production process that is important, but explicitly the origin.
Unofficial gin varieties leave the producers plenty of room for experimentation, as they are not subject to any official specifications. This often results in unusual creations with even more unusual flavours.
