Nuts are rich in form, aromatic and tasty, they are excellent donors of vitamins and minerals and even prevent heart attacks: Long-term studies confirm a clear link between nut consumption and a healthy heart.

The Monopolwerke, founded in 1879 in Steinbach Hallenberg, Thuringia, established its worldwide reputation with the production of corkscrews (and thus at the same time the reputation of Thuringia as the cradle of German corkscrew production).
