Meet the Author of Distilled Spirits Sensory Science
George F. Manska is the Managing Partner of Sensorium Publishing Co., LLC, and Chief of Research & Development at Arsilica, Inc. In this role, his work centers on a fundamental sensory issue: improving the repeatability, bias recognition, and diagnostic utility of sensory evaluation of ethanol-based beverages through measurement discipline, and standards-based methodology. Accordingly, Distilled Spirits Sensory Science addresses Arsilica’s research into distilled spirits.
Manska is a co-inventor of the NEAT (Naturally Engineered Aroma Technology) sensory evaluation glass for spirits, conceived in 2002, developed through the application of physical modeling, vapor-phase chemistry, and psychophysics to address practical problems in spirits assessment, and finally released for production in 2011.
His primary focus is on the well-known challenge that ethanol vapor dominates olfactory perception and suppresses aroma discrimination. His approach emphasizes testable mechanisms over tradition. As a result, he encourages evaluators to treat nosing and tasting as measurement tasks rather than rituals, using appropriate tools and methods to build a standard, reusable, dependable framework.
Education and professional background
Manska holds a Bachelor of Science degree in Mechanical Engineering (North Carolina State University, 1967) and completed postgraduate studies in business management at Wayne State University (1974). His early career was in engineering and product development, followed by roles in product planning and technical leadership in technology and communications. Subsequently, he held a Senior VP position in wealth management, with Chartered Financial Consultant (ChFC) and Chartered Life Underwriter (CLU) designations (1997). Manska launched Arsilica, Inc., a Nevada C corporation and a sensory research and consulting firm, in 2011 to formalize and further investigate evaluation methodology for all alcohol-content beverages.
In summary, this career progression and diversity have shaped the pragmatic, systems-focused perspective that informs his work. Operationally, the process is simple: define the issue, model it, validate it, standardize where possible, apply it, and evaluate the results.
Standards and professional service
Manska is a member of ASTM International Committee E18 on Sensory Evaluation and the Society of Sensory Professionals. In addition, he serves on the Advisory Board of the College of Sciences at the University of Nevada, Las Vegas. Beyond formal sensory organizations, Manska holds industry memberships and affiliations tied to the book’s applied context, spanning production, distribution, and professional practice. Additionally, he serves as a guest lecturer and supports local educational programming in sensory science. Manska served as the Maitre of the Commanderie de Bordeaux for 9 years and as a member for 15 years, gaining relevant experience in tasting and analyzing wine and spirits.
Research, patents, and publications
Manska’s research spans the evaluation of spirits, beer, and wine. Emphasis is on designing sensory vessels and protocols to reduce ethanol interference. Moreover, his work includes multiple patents in functional beverage glassware. Additionally, he is developing mathematical models for diagnostic vessels used with ethanol-based liquids. He has published in trade venues, as well as authored an open-access, peer-reviewed journal paper on this work.
Why Distilled Spirits Sensory Science was written
The author wrote Distilled Spirits Sensory Science for serious learners. Students, educators, professional judges, distillers, and technically minded enthusiasts who want a defensible evaluation framework. The book pursues three aims:
- First, establish a shared, evidence-based vocabulary and method for spirits sensory evaluation that can be taught, practiced, and critiqued. As a result, the communication of evaluation notes becomes usable and repeatable.
- Second, connect production choices (raw materials, fermentation, distillation, aging, finishing, and packaging) to perceptual sensory outcomes through proven, testable, and explainable mechanisms.
- Finally, replace tradition-driven claims and questionable, opinionated marketing narratives with discipline in measurement, repeatability, and transparent, rational reasoning.
Disclosure: The author has contributed to the design of a sensory evaluation vessel discussed in the book. Accordingly, discussion and analysis are presented for scientific and educational purposes. For transparency in academic review, supporting materials (CV-style summary, patent documentation, and publication links) are available upon request.
