Marianne Eaves

Coming Up

Chemical Engineering provided the technical base before the whiskey work began. Marianne Eaves trained at University of Louisville, grounding the later distilling practice in process, measurement, and cause-and-effect thinking. As an intern at Brown-Forman from 2009, that training moved into daily production culture: grain, water, barrels, time, and the sensory distinctions that separate sound spirit from better spirit. Master tasting at Brown-Forman in 2014–2015 put sensory discipline into a formal role. For Eaves, nosing and evaluating were not adjuncts to production; they were part of the production intelligence. The work required comparison, calibration, and repeated return to the glass with increasing precision. Restoration work in whiskey asks for both respect for a site and hard production competence. Mashbills, fermentation, distillation, and taste were the practical tools for bringing production back into use, and the move widened her view of Kentucky whiskey beyond one company’s frame. Blind tasting is a useful correction against label, reputation, and expectation. After that run, Eaves worked as a consultant and, from 2020, as creator and curator at Eaves Blind. The method matches a recurring part of her practice: remove the cue, then let the palate do its work. Today, she is founder and Master Distiller of Forbidden Bourbon, a role she has held since 2023.

Where They Are Now

At Eaves LLC in Lexington, Kentucky, she is Master Distiller. The work brings together Chemical Engineering, blind tasting, palate training, mashbills, fermentation, and distillation as one operating system. In Eaves’s practice, analytical control and sensory assessment are not competing languages; they are successive checks from formulation to final glass. Forbidden Bourbon is a bourbon inspired by Southern cooking, using white corn, white wheat, and a high percentage of barley as a new twist on tradition. The idea is expressed through whiskey’s own materials and processes: grain choice, fermentation, distillation, and maturation. It reflects Eaves’s interest in revisiting familiar bourbon foundations without cutting them away from their roots.

Signature

Chemical Engineering gives this distilling practice its structure. Marianne Eaves works from an insistence on understanding process before judging outcome: why a spirit behaves as it does, how production choices register in aroma and texture, and where measurement stops short of the final sensory call. The signature is the working balance between controlled method and an open glass.

In Their Words “I discovered just how much more there was to Kentucky than the Brown-Forman family; I was drinking their very delicious Kool-Aid, but Kentucky whiskey’s history goes so much deeper.” “I have had a few ‘A-ha!’ moments in my career as a distiller, and going from Brown-Forman to Castle & Key was one of them.”
