What does it mean to say a wine has a "nice mesh"?

Hello there! I'm Dr. Vinifera, but you can call me Vinny. Ask me your toughest wine questions, from the fine points of etiquette to the science of winemaking. And don't worry, I'm no wine snob—you can also ask me those "dumb questions" you're too embarrased to ask your wine geek friends! I hope you find my answers educational, empowering and even amusing. And don't forget to check out my most asked questions and my full archives for all my Q&A classics.
Dear Dr. Vinny,
Can you please define what “nice mesh” means when talking about Riesling?

Dear Michael,
Even though I’m guessing you came across the term “nice mesh” in a Riesling review, it isn’t actually specific to the Riesling grape. Outside the world of wine, “mesh” refers to strands woven together, so using “nice mesh” as a metaphor to describe a wine suggests that its elements fit together well. Similar ways for wine writers to describe different elements interconnected in harmony might be “well woven” or “tightly knit.”
