This bread’s given name is a classic example of not really telling the whole story, because it has a substantial proportion of high gluten (bakers/very strong) flour in it as well: 50% high-gluten flour, 25% rye, and 25% whole-wheat. Without the high gluten flour it would look and feel quite different. The rye is all made into the pre-ferment and the white flour and the whole-wheat flour are added when you mix the dough.

Be prepared to adjust the water and flour depending on how your flour behaves. Observe the condition of the dough in the video and aim for that.
Maria Paola tells me that this roll is called a michetta in her part of Italy and has been kindly sending me translations of Italian recipes after I posted asking for help on Twitter about a type of yeast called lievito di birra. I was slightly confused as to whether this was what Italians call fresh yeast or whether it was the yeast that is used to brew beer specifically. They’re all the same family but beer yeasts have different characteristics from the strain used to make bread. However this yeast is basically the same stuff we use for bread.
