What is the circulatory cold compounding method?

The circulatory cold compounding method is characterized by the repeated infusion of botanicals in a base spirit at colder temperatures. This process typically involves a mesh tray in which the botanicals are placed. The base spirit is then pumped over this tray in a circulating fashion, allowing the flavors and aromas from the botanicals to be extracted without the application of heat. This method is prized for its ability to preserve the delicate flavors that might be lost in hotter processes, such as distillation. This technique is particularly applicable in the production of flavored spirits like gin, where the nuanced characteristics of the botanicals can greatly influence the final product's profile.

The other options do not accurately describe this method. For example, the infusion of botanicals under high pressure does not represent cold compounding, the high-heat distillation process fundamentally differs from the cold extraction required for the circulatory method, and fermentation techniques are unrelated to the infusion of botanicals in spirits.
