An aerospace engineer by training, Jeb Dunnuck grew up on a farm in rural Indiana where whole milk was the beverage of choice and wine was hard to come by. It wasn't until 1996, when living abroad and traveling through Europe, that he became interested in fine wine.

Moving to upstate New York in 1999 to work for Lockheed Martin, and later to Colorado in 2001 to work for Ball Aerospace, he traveled extensively throughout the wine regions of Europe and the United States, where he quickly developed a passion for the wines of the Rhône valley and the Rhone Ranger Movement in California and Washington. To gain a better understanding of the business side of the wine industry, he took a temporary wine retail position in 2006.

Jeb launched the "The Rhône Report" publication and website in 2008 and began releasing a quarterly newsletter reviewing Rhône variety wines from around the world. Completely independent and including coverage on wines from France, Spain, Australia, and both California and Washington in the United States, the publication continued to gain in popularity and subscribers, and by 2013, was read in over 24 counties and seen as one of the leading authorities on Rhône variety wines.

In 2013, after being approached by Robert Parker to join The Wine Advocate team, Jeb gave up his engineering career and now writes full-time covering the wines of the Rhône Valley (North and South), Southern France, Washington, and Central & Southern California. He resides in Colorado, with his wife Traci and two dogs, where he pretends to rock climb and race a bicycle
