Marc Vetri, Claire Kopp McWilliams, and David Joachim: Why Bolted Flour is a Game Changer.  In this panel discussion by the multi-award-winning authors of Mastering Bread, we will explore the ascent of not only bolted flour (also known as high extraction flour), and why it makes better bread, but also how the importance of sourcing and matching your wheat to your style of bread will be a growing influence in both local and national bread baking.
