They are called the "New Beer-Makers" in this very interesting and well-written article. And their strategy is not only spicing up the craft beer scene in Europe, it's having the same effect here. As the article will show, it's their penchant for experimentation that drives the movement. And experimentation is critical to the beer consumer as well, as it drives beer lovers like us to explore new horizons.
H/T to Patty for the heads up. It's nice to know that my former students are reading publications called "More Intelligent Life."
