Our patented TerrePURE® technology has been formulated around significant scientific research and consumer taste testing, ensuring you get the highest quality, best tasting spirits possible. To illustrate this point, we’ve compiled some information relating to both alcohol in general, and our technology specifically, that will help you understand exactly how revolutionary the process is.

Congeners and hangovers

Considerable research has shown that congeners, impurities left over from distillation, are contributors to an alcohol “hangover.” Scientists continually seek more concrete answers around what the most important factors causing or influencing hangovers may be, but congeners are thought to play a significant role.

A 2006 study by Joris Verster in The Alcohol Hangover-A Puzzling Phenomenon concluded that consuming alcoholic beverages with higher levels of congeners results in a more severe hangover later (1).

In their article Alcohol Hangover: Mechanisms and Mediators, Drs. Robert Swift and Dena Davidson discuss specific congeners (such as methanol and the toxic formaldehyde and formic acids) and how spirits high in these congeners are typically associated with hangover effects (2).

An article in Alcoholism: Clinical and Experimental Research also enumerates many congeners. Several of these specific congeners are addressed with our TerrePURE® technology (3).

TerrePURE® reduces these congeners

Our technology has been independently proven, over several studies done at different labs, to reduce the amount of congeners (particularly isobutanol, amyl alcohols, propanol, and methanol) present in distilled spirits. TerrePURE® has also been shown to reduce free radicals by up to 70%. See the next chart for some of these results.

TerrePURE® Congener Reduction

Our TerrePURE® technology has also been proven, in a 2010 College of Charleston Chemistry Department study, to result in the esterification of fatty acids present in spirits. In technical terms, our technology converts hexadecanoic acid and octadecanonic acid into the ethyl esters of each.

In real terms, our technology transforms harsh-tasting acids into pleasant-tasting esters that are not present in other spirits.

TerrePURE® Esterification of fatty acids

Together the data show that our patented TerrePURE® technology represents a truly revolutionary evolution of spirits production (we understand the gravity of this statement and do not use it lightly). Not only does TerrePURE® produce higher quality spirits than traditional means (filtration, re-distillation, or barrel aging), it permanently transforms them, in a beneficial manner, at a fundamental level.

This is an entirely new, novel way of producing the cleanest spirits made by man

While the research is interesting to consider, the true test is always through a tasting. We are constantly expanding our sales force to reach new customers in every state and encourage you to contact us for a tasting, subject to applicable state regulations. If you qualify for our private label or private brand products, you owe it to yourself to explore this option today.
