Esters
Esters are important natural compounds that give alcoholic beverages their distinctive flavors and aromas. Think of them as the natural flavor molecules that make whiskey taste like fruit, or give rum its sweet, tropical notes. In spirits production, esters form during fermentation and aging processes. When you see this term in a resume, it usually indicates someone has experience with the technical side of flavor development in alcoholic beverages. This knowledge is similar to how a chef understands spices, but for the spirits industry.

Example Interview Questions
Senior Level Questions
Q: How do you manage ester production during fermentation to achieve specific flavor profiles?
Expected Answer: A senior distiller should explain how temperature, yeast selection, and fermentation conditions affect ester formation, and how they've used this knowledge to develop new products or improve existing ones.
Q: What methods do you use to analyze and monitor ester levels in spirits?
Expected Answer: They should discuss quality control procedures, sampling methods, and how they interpret analysis results to maintain product consistency and quality.
Mid Level Questions
Q: What role do esters play in spirit maturation?
Expected Answer: Should explain how esters develop during aging, their impact on flavor, and how barrel conditions affect ester formation.
Q: How do you troubleshoot unwanted ester formation in production?
Expected Answer: Should describe common problems, their causes, and corrective actions to maintain proper ester levels and desired flavor profiles.
Junior Level Questions
Q: What are esters and why are they important in spirits production?
Expected Answer: Should demonstrate basic understanding of esters as flavor compounds and their role in creating desirable tastes and aromas in spirits.
Q: What are the main factors that influence ester formation during fermentation?
Expected Answer: Should identify basic factors like temperature, yeast type, and fermentation time as influences on ester production.
