Seed bread reproduction

I bought this amazingly delicious bread from a bakery in my hometown
It was dense but it felt light and with a great crispy crust and plenty of grains.
Few days after tasting it I started to develop an obsession to discover the mysteries of this bread
I even posted a forum thread to share this urge with the TFL experts
