Red wine mash flooder FD-MÜ

Rotweinmaische-Überfluter FD-MÜ

Globally successful

Speidel’s FD-MÜ is an upright standing red wine mash fermentation tank with a simple but efficient technology. After the fermentation has started and a marc cake has formed about half of the content is discharged into an interim tank. The marc cake descends to the ground, breaks into pieces and is 'opened' by a system of rods.

Afterwards the juice is pumped in again via a self-rotating sprinkling system and the smashed marc cake is flooded. The pigments are washed out. This procedure is repeated several times. The principle of the 'remontage' or reassembly has been practised successfully all over the world.
