About this Episode

John Angus approaches the mechanics of flavor creation in spirits through the lens of a chemist but with the soul of an educator, breaking down complex processes and cutting-edge science in practical ways that spirits makers can use and drinkers can understand. He uses the tools of analytical chemistry to unlock the mechanisms that form flavor and aroma through the distilling and maturation processes, and makes complex processes more accessible.

In this episode, host Molly Troupe and Angus discuss:

  • the complex chemistry of cask finishes and how port, sherry, rum, cognac, and madeira casks influence flavor
  • how environmental factors such as temperature and humidity make every barrel unique
  • why modeling maturation poses such a scientific challenge
  • processes for sensory evaluation and documentation that even small distilleries can regularly employ
  • using infographics to simplify complex chemical interactions

And more.

G&D Chillers: G&D Chillers understands that each distillery’s chilling requirements are unique. On every distillery project, G&D offers the front-end design and engineering your team needs at no cost to you. Hank Pressley, head distiller at Moon Drop Distillery says, “Early on, we made a decision to partner with quality American-made companies. One of those companies was G&D Chillers, and we are proud of that choice. Our equipment from them has run long and strong. We put our first barrel in our rickhouse in September 2021, and in the next 3 years we have put back more than another 540 barrels. What a great decision to team up with a company like G&D Chillers.” Reach out for a quote today at gdchillers.com.
