exert, exert yourself, wine press, tannin

這 wine press 是器 不過新約中有翻譯成"池"的 A wine press is a device used to extract juice from crushed grapes during wine making. There are a number of different styles of presses that are used by wine makers but their overall functionality is the same. Each style of press exerts controlled pressure in order to free the juice from the fruit (most often grapes). The pressure must be controlled, especially with grapes, in order to avoid crushing the seeds and releasing a great deal of undesirable tannins into the wine.^[1] Wikipedia article "Wine press".
