Smaller fragments are packed in perforated bags or wire cages that are hung in the steel tanks for removal.

In part, the use already during the maceration, resulting in a correspondingly higher extraction the oakwood fabrics is achieved. In addition, oak-derived extracts are also available in the form of powders, tablets or essences.
