Brenna Quigley


Brenna doesn’t mind getting her hands dirty. As a geologist and terroir specialist who founded and hosts the audio guide Roadside Terroir, she is committed to thoughtfully applying the science of geology to the world of wine through both education and hands-on vineyard investigations. Brenna works with wine professionals in all areas of the trade, from growers in France to importers and buyers in the US, in order to precisely define the most impactful elements of their terroirs in a relevant and approachable manner.

After receiving her bachelor’s degree in Aquatic Biology and Geology from the University of California, Santa Barbara in 2012, she stayed on to earn her masters in Geology in 2015. Her research focused on geologic mapping and structural geology (how and why rocks deform), and she has also worked extensively in the mining industry. Brenna spent her free time at UCSB exploring the surrounding wine country, and began working at her favorite tasting room on the weekends. It was there, working with Seth and Magan Kunin, that she fell in love with the wine industry and the complex concept of terroir.

Brenna - who is based in Napa - recently had the privilege of working with The Source Imports as well as Becky Wasserman & Co. to explore and research the terroirs of France. Her current projects take her all over the world, from her backyard at Domaine de la Côte in Lompoc, California to further investigations in Spain, Austria, Germany, and Italy.
