Once the fermentation process that creates the methane is finished, the remaining solid matter, or "digestate" is used as an organic fertilizer for crops that will later be used as feedstock for the animals.
This is also a type of alcohol that can be made by fermenting sugar (though the fermentation is done by a species of bacterium rather than by yeast), and it has some advantages over ethanol.
Many creative processes are sabotaged at the beginning, when impatient designers rush through or skip the creative fermentation process in order to get to the so-called good stuff.

The guides, like those at Maker's Mark, stress the use of traditional methods: the slow fermentation of sour mash in vats made of cypress, the distillation in copper-pot stills (Labrot and Graham use three instead of the usual two), the regular sampling of barrels by discriminating imbibers with decades of experience, to achieve just the right taste.
Thats simply a matter of inserting the gene into cells, growing the cells in fermentation vats and filtering the protein out of the broth.
