First, the spirit is gently heated to 90 degrees F and then enters the extraction vessel. While being stirred, a high energy field is delivered, maintaining a slight vacuum, and food grade gas begins to flow. In the first phase, hydrogen bonds are broken, and certain offensive congeners are removed. In the second phase, we switch to a reactive gas which causes other desirable compounds to form. Fusel oils and fatty acids are harsh compounds and are affected differently in the process. A large fraction of fusel oils are ejected entirely while fatty acids are converted to form flavor esters.  

It's these esters that give top shelf spirits their pleasant mouthfeel and appealing flavor. This all takes place in 20 minutes, near ambient temperature, with losses being undetectable!

When producing a premium vodka for example, distillers use distillation and filtration to “clean up” the base spirit known as Grain Neutral Alcohol (GNS). Distillation is energy intensive, and the alcohol losses are high. The longer you distill, the cleaner it gets, but you experience more alcohol loss. Our Persedo C.R.A.F.T.® technology makes it cleaner, using 90% less energy, and we have ZERO losses in the process of purification!

Congeners are substances in spirits, other than the desired type of alcohol and ethanol, produced during fermentation. These substances include small amounts of chemicals such as methanol and other alcohols, acetone, acetaldehyde, esters, tannins, and aldehydes. They are often responsible for some of a spirit’s physiological effects. 

Our process is tuned to remove controlled amounts of congeners which are not always preferable in a spirit, including:

• spicy, hot solvent-tasting fusel alcohols like amyl and butyl alcohols

• unpleasant, harsh acetals like acetaldehyde and

• toxic methanol and iso-propanol.

No. Food-grade, insert gases flow through the spirit and exit completely under vacuum. Organoleptic (flavor and aroma) lab analysis shows that certain desirable, new flavors and aromas are created.

To create Gentle Ben bourbon, white whiskey (AKA new-make) is polished prior to putting it in a new, charred, American oak barrel. By doing it this way, many of the harsh congeners are dealt with before barreling. Addressing many of the congeners prior to barreling makes the barrel’s job a little easier.  

Yes, it is! However, we have been approached to produce and bottle spirits for other brand owners. If other brands use the technology, this will be represented on their label.
