There are various types of gin, therefore production methods. Normally the most known and consumed gin is the London dry. This does not indicate the origin as it can be distilled all over the world, but indicates the production method.

This method consists in placing the alcohol and all the components of the gin recipe in the still (strictly copper). Here’s how the so-called “botanicals” give their flavor. (Enrico Rovella)
