Sacred Gin is a grain-based spirit distilled using a very specific process of reduced-temperature distillation. The distillation--with an infusion of herbs--creates a flavored vodka where each of the herbs gain resonance and vigor through distilling each botanical separately in near-vacuum conditions.
From the website, we have this daunting description of the process: "Reduced temperature distillation is achieved by distilling each botanical separately under a vacuum ranging from 1/12th atmosphere to 1/6th atmosphere. There is also a "negative activated carbon effect" from distilling the botanicals separately which can best be explained by considering the distillation of all botanicals together, in which the presence of just one single aroma absorbing element will affect the entire gin. If this hypothetical mix of botanicals were distilled separately, the single aroma absorbing element would be unable to absorb flavors from its neighboring botanicals, and hence the overall flavor of the resultant gin is enhanced. This reduced pressure/reduced temperature also means that the complex 3 dimensional terpenes such as limonene, geraniol, pinene, eucalyptol and terpenoids such as citral, menthol etc. do not get the opportunity to stereoisomerise into their more "stewed" versions, which would be recognised as "marmalady" and bitter flavours so prevalent in gins distilled at higher temperatures."
