Question: How does the Persedo Enhancement Process Work?

Answer:

Previously distilled spirits such as whiskey, tequila, rum or gin, or high proof grain neutral spirit are placed under a mild vacuum. Simultaneously, the spirit is gently warmed and placed in an extremely high energy field. This creates supersonically collapsing voids in the solution which undesirable off-flavors and odors penetrate as vapor. These voids are swept with bubbles of inert food-grade gas before they collapse. Further, the energetic creation of the voids generates free radicals that further polish the solution. This is accomplished with precise control of 7 dynamic process settings. In a second phase, a reactive food-grade gas is introduced to convert waxy, harsh fatty acids and similar compounds to form flavorful esters, a process similar to that which occurs in barrel aging.

Question: What undesirable compounds does this process remove?

Answer:

The system is tuned to target removal of harsh fusel oils and the conversion of unpleasant fatty acids. Persedo works with distillers to ensure beneficial flavor and aroma profiles are maintained.

Question: Can you expand upon removal of certain congeners?

Answer:

The Persedo process can be 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.

Some of these congeners are removed by distillers in the heads and tails, but some end up in the product.

• The Persedo process is able to temporarily break the hydrogen bonds which tightly hold these congeners in the distillate.

• This is accomplished by applying extremely high energy and sweeping the system with an inert food-grade gas under vacuum to pull undesirable congeners out of solution.

• In traditional distillation, much of the product is lost to remove off-flavors and off-odors.

• Persedo process is completed at room temperature, so little ethanol is lost, that is, the proof doesn’t fall

Question: Can you expand on unmasking of the underlying distillate flavor and aroma?

Answer:

Receptors in the mouth, tongue, and nose are overwhelmed and anesthetized by harsh components in the spirit. We address co-distilled congeners that mask the delicate flavors, which then can be detected by the palate.

Question: With respect to barrel-aged spirits, is the un-aged distillage enhanced before entering the barrel or after it has aged?

Answer:

The polishing step can be performed before or after barreling. Different profiles can be obtained by polishing before and/or after barreling.

Question: Should the product be processed before or after proofing?

Answer:

We produce many of the same esters and remove many of the same undesirable aroma and off flavors at any proof. Given that polarity affects solubility, product proof is one of the numerous parameters we can alter to polish a distiller’s spirit and provide them with unique expressions.

Question: Is anything added to the spirit in the process?

Answer:

We pass food-grade inert gases through the solution, which exit completely under vacuum. Organoleptic (flavor and aroma) lab analysis shows that certain desirable new flavors and aromas are created.

Question: The System uses a combination of energy injection, vacuum, and extractive food-grade gases. Why does this work better than removing these compounds?

Answer:

We create a temporary state in which we break hydrogen bonds that typically allow compounds to stay dissolved in ethanol. This allows the undesirable compounds to be stripped away quickly, efficiently and without alcohol loss.

Question: What equipment would need to be leased?

Answer:

A fully automated processing skid and control system. Licensing fees are based on the volume of spirits polished.

Question: What is the size footprint of the equipment in terms of a distillery?

Answer:

25’ x 25’

Question: What is the capacity of the equipment?

Answer:

Small unit – up to 750 wine gallons per 8-hour day

Larger unit – 1,200-1,500 wine gallons per 8-hour day

Question: Does the product get shipped to Persedo, processed, shipped back, then bottled or does Persedo offer bottling services?

Answer:

Persedo does not offer bottling services. However, bulk spirit processing is available. Persedo can receive bulk spirits, perform the polishing process and ship back to the distiller in suitable bulk containers.

Question: How does Persedo address safety concerns in its equipment design?

Answer:

All equipment is designed and professionally engineered for intrinsically safe operation and meets the most stringent requirements for any modern distillery environment.
