context_page_description: The history of the wine press and of pressing is nearly as old as the history of wine itself with the remains of wine presses providing some of the longest-serving evidence of organised viticulture and winemaking in the ancient world. The earliest wine press was probably the human foot or hand, crushing and squeezing grapes into a bag or container where the contents would ferment.
  The pressure applied by these manual means was limited and these early wines were probably pale in colour and body, and eventually ancient winemakers sought out alternative means of pressing their wine. By at least the 18th dynasty, the ancient Egyptians were employing a "sack press" made of cloth that was squeezed with the aid of a giant tourniquet. The use of a wine press in winemaking is mentioned frequently in the Bible but these presses were more elaboration of treading lagars where grapes that were tread by feet with the juice running off into special basins.
context_section_description: With relatively modest changes, the basket press has continued to be widely used for centuries since its introduction by both small artisan winemakers to large Champagne houses. In Europe, basket presses with hydraulic machinery can be found throughout Sauternes, Burgundy and parts of Italy.
  In the 20th century, wine presses advanced from the vertical style pressing of the basket press and ancient wine press to horizontal pressing with pressure either being applied at one or both ends or from the side through use of an airbag or bladder. These new presses were categorize as "batch", which like the basket press had to have the pomace emptied and grapes reloaded, and as "continuous" where a belt or Archimedes' screw would subject the grapes/pomace to increasing pressure from one end of the press to the other with new grapes being added and the pomace being continuously removed.
  Another advancement in the horizontal batch press was the complete enclosure of the press (sometimes called "tank press") that reduced the exposure of the grape must to air. Some advance presses can even be flushed with nitrogen to create a complete anaerobic environment that can be desired for wine making with white wine grapes. Additionally, many of today's modern presses are computerized which allows the operator to control exactly how much pressure is being applied to the grape skins and for how many cycles.
