View From a Press

As we move towards completion of harvest, we are seeing more and more of the inside our presses. This photo (taken while complying with OSHA approved Confined Space Entry techniques!) is of the inside of a membrane press at Goldeneye. On the right hand side is the bladder, which inflates and deflates based on the press program and cycle, and which presses the grapes or pomace against the channels on the left hand side. In this case the drain channels have been removed for cleaning. The wine or juice runs out and into the waiting pan below, from which it is pumped to tank. The cylinder also rotates, which acts to break up the cake of skins and seeds, allowing more juice or wine to flow. Having an appropriate press cycle is critical, as the number of rotations, pressure, and timing can all have significant effects on the quality and yield of your pressing.
