A Gin basket (Carter Head) is used in the Vapor Infusion of botanicals, most commonly in gin. It is designed to hold various botanicals in the vapor path of a still in order to extract flavor compounds from the source material. Normally constructed of a metal mesh it allows the vapor to interact with the materials in the basket.
The Gin basket can be in the column directly above the boiler (inset). The reflux from this will fall back into the main boiler. An offset Gin basket will not allow the reflux to fall back into the boiler. For some installations the offset Gin basket will have a liquid feed to the boiler.
