What can you learn about the history of our planet from a glass of wine?

Roadside Terroir is an audio travel guide for wine lovers who want to dig into the world of geology, wine, and terroir. Join geologist Brenna Quigley on a road trip as she explores the unique geologic history of wine regions around the world. Our goal is to define the sense of a place through the lens of how it formed over millions of years. Each episode contains insights from local growers and wine producers, as well as chefs, sommeliers, locals, and friends in addition to the detailed geologic descriptions of the terroirs. Our website and instagram include photos, maps, and additional information so you can follow along from anywhere in the world.

Brenna Quigley
Founder, Geologist, Host

Brenna wants nothing more than to tell you a story about the rocks that surround you every day, and how they fit into the creation of our planet.

She believes the world would be a better place if we could all think in timescales starting in the millions of years, and that wine and terroir is the very best place to start.

She received her Bachelor’s Degree in Aquatic Biology and Geology from the University of California, Santa Barbara in 2012, where she stayed on to earn her Masters in Geology with Dr. Phil Gans in 2015. Her research focused on geologic mapping and structural geology (how and why rocks deform). She has also worked extensively in the mining industry where she further developed her skills in geologic mapping and interpretation, soil sampling, and geophysical surveying.

Today 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. Her work takes her all over the world, from Santa Barbara to Burgundy, Napa to Barolo, Galicia to Vienna, and much more.​

Connor developed his craft in New York, receiving a master’s degree in music technology from NYU. His research focused on the correlation of certain perceptual and objective qualities of recorded audio, identifying a novel approach for measuring sensory phenomena.

When he's not producing music, you can find him running trails, throwing a baseball around, or reading outside in his garden sipping on some wine trying to come up with the right words to describe the sensations going on as he takes sip after sip, settling on "...hmm. Interesting".
