Speidel Kernobstmühle aus Sandwichrotation hergestellt

Sandwich rotation

Not one, but two good sides

You can read about »tradition and innovation« in any advertising brochure. At Speidel, however, it is clear that 100 years of experience in tank construction really do make a difference. Because when it comes to new manufacturing processes, no one can fool us.

The fermentation egg, for example, was manufactured in a sandwich rotation process with two wall layers, but in a single operation. Thanks to its particularly smooth surface, the inner layer is perfect for the fermentation process of wine and beer.
