Closed Pressing System

Half of the press drum is covered by an impermeable membrane, while there are perforated draining channels all along the other half. A built-in compressor is used to establish the desired pressure within the drum. This inflates the membrane, which consequently presses the grape mass and drains the must. Must then flows through draining openings into a collection pan. Soft grape and grape pomace membrane pressing with compressed air prevents any mechanical damage to the grapes, thus ensuring a production of high-quality must and wine.

The draining channels are electropolished. Advantages of an electropolished surface:

  • reduced grape pomace sticking to the drum surface, which means better must flow through drainage holes,
  • easier drum cleaning, reduced water consumption,
  • surface looks glossy and shiny,
  • reduced possibility of coating on the material,
  • increased corrosion resistance of the material.

Grape presses with a closed pressing system can also be used for grape pomace fermentation and maceration inside the drum. In this case, it is recommended that the press drum also be equipped with a cooling jacket (pillow plate).

The main advantage of a closed pressing system is a reduced possibility of must oxidation.

Kinnegar Brewing // Ireland

Kinnegar Brewing // Ireland

County Donegal

At Kinnegar they pair brewing tradition with a contemporary sense of adventure to produce clean, crisp, full-flavoured farmhouse beers. The brewery is named after the nearby Kinnegar Beach just north of Rathmullan in County Donegal. In 2017, Kinnegar opened K2, a new, state-of-the-art facility in nearby Letterkenny. While the clinking of bottles coming off their line no longer mingles with the bleating of sheep from the surrounding fields, the farmhouse ethos at the core of what Kinnegar does remains the same. They don’t filter or pasteurise, and they let their industrious little friends, the yeast, carbonate the beer naturally during fermentation.
