Ever been to a tasting room and heard the staff start talking about what grape clones are in your wine? They start listing off what sounds like random numbers, and it gets confusing fast! I wrote an article for Wine Enthusiast about what a grape clone is and what some common ones are. If you’d like to find out more, read it here!
And if you’d really like to nerd out and learn about the fascinating history of how we wound up with so many grape clones in the US, Nancy Sweet, the historian at Foundation Plant Services at UC Davis who kindly helped me get started with research for my article, wrote a very thorough e-book that is a great resource. Cheers!
