About

Dr. Julie A. Culbert is a leading researcher in wine chemistry, with a particular focus on the molecular drivers of sparkling wine quality. Her work bridges analytical chemistry and sensory science to unravel how specific compounds influence the texture and stability of wine foam—a critical attribute for premium sparkling wines. In her highly cited 2017 study, "Soluble Protein and Amino Acid Content Affects the Foam Quality of Sparkling Wine," Dr. Culbert demonstrated that both the concentration and composition of proteins and amino acids directly govern foam formation and persistence, challenging earlier assumptions about their roles. This foundational work, which has garnered over 30 citations, has become essential reading for enologists and winemakers seeking to optimize production processes. Beyond this, Dr. Culbert’s broader research portfolio explores the interplay of grape variety, fermentation, and aging on wine chemistry, contributing to a deeper understanding of how viticultural and oenological choices shape final product quality. Her meticulous, data-driven approach has made her a respected voice in the field, and her insights continue to inform both academic research and practical winemaking.
