The use of good charcoal is very important for the taste of the products to be prepared and to achieve and maintain a good temperature. This combination of selected types of hard wood is an efficient and sustainable fuel for your Big Green Egg. The beech and birch trees used for the charcoal are grown in a sustainably maintained forest, which is why the charcoal owes its FSC certificate. The 9kg bag contains larger pieces and is therefore better suited for low & slow cooking. The 4.5kg bag consists of smaller pieces of charcoal and is therefore perfect for the smaller sizes of EGGs.
