Fermentation process occurring in「each wine jar」although the separate elements for「each」might make the most sense in this glyph:「slowly descending clotted clumps from bottleneck shape.」Finally, after the level of alcohol builds up in wine enough to kill the inhabiting yeast, the dead yeast and lees will clump into chunks, slowly descend to the bottom of the jar, settle and harden.「Spread feet」and「coming down from above」refer to wine LEES, and to whitish CURDS of clumped milk that has soured or with alcohol poured into it causing curds and whey to form, SOUR CREAM, and to all such DAIRY products.
　A similar process is used to make tōfu, by causing soy milk to curdle and then settle (by adding an alkaline solution called nigari, not alcohol). See 奴「female sex slave crotch」and its meaning as 'curdled soy milk, cold tōfu curds.'
　Further thought about the individual elements might create an unappetizing recollection each time you see cheese in the future, hence doing so is discouraged. Nevertheless, for the brave, elements are「cock, rooster」with「spread feet above orifice」depicting the stance used by a cock standing with one foot on each side of the hen's tail while mounting upon her back in order to copulate by dripping ejaculate into her everted cloaca. This area of a hen is often bald of feathers for this reason after continued use. As for the connection with a「cock」and a concubine's deep skin folds in「each」of her no-longer-integrated foot「orifices」and what sort of clumping, clotting, curdled fermentation and slow descent occurs after continued use, you are on your own to imagine.
　It is no coincidence that the English root word「broth」meaning fluids in which meat has been heated, cooked and fired, is used to describe「someone who broths」as a brother and a「house for brothing」as a brothel.
