If I remembered anything about Rheinhessen, the largest wine region in Germany, from my WSET Level 3 textbook, it was that there wasn’t much to remember. With the exception of several renowned producers like Klaus Peter Keller, it was vast and flat, its output forgettable. But then, in early 2025, I started seeing its name again and again in the newsletter I receive from Leon & Son in Brooklyn, one of the most forward-looking wine shops in the country.
