We at OPA ERWIN only process sustainably grown moonwood. According to old knowledge, we cut our moonwood in winter just before new moon, which gives it very special properties.
Which trees become moonwood?
The oaks we carefully select as moon wood often come from the higher regions of the Swabian Alps. Here the climate is harsher and colder and winter lasts longer. For this reason, the oak trees grow more slowly. This is easy to read from the annual rings, which are narrower and closer together.
