I don’t drink gin myself but when I built my still a lot of friends asked me if I could make Gin so I did some research and found out how to do it and even the exact ingredients used in Bombay Sapphire as this was the Gin they wanted.
Now there are 2 ways that Gin makers make their Gin, Steeping and Vapour Infusion, this instructable uses the same method that Bombay Sapphire use which is Infusion.
Botanical's : what does this mean? Well it’s the plant matter and spices that are used to flavour the Gin.
What is a Steeped Gin, to make a steeped Gin, which is the most common way to make Gin, the Gin makers put their botanicals in the still boiler along with the spirit and then leave it for 24 hours. After that they boil it with the botanical's still in it to get the spirit from it.
Vapour infused Gin is different what they do is they have a special basket which they put the botanical's and then they pass the spirit vapour over it and the vapour picks up the flavours on the way.
