Sure, the milk is nutritious but there's not enough from a rabbit to be worth bothering with for a human. And milking rabbits would not be like milking cows. Cows, and even many goat and sheep, stand relatively still to be milked. Rabbits can't and won't and there's no good way to make them.
The theory that wine was discovered by accident is most likely correct because wine grapes contain all the necessary ingredients for wine, including pulp, juice, and seeds that possess all the acids, sugars, tannins, minerals, and vitamins that are found in wine.
Sediment During Wine Production. The initial sediment which forms in wine appears during the fermentation process and is called lees.. The lees sediment consists of dead yeast cells, proteins, stems, bits of skin, and other solid matter that has settled to the bottom of the fermentation tanks. Wine is left with the lees for a while so it can develop more character and complexity, but if the mixture is handled incorrectly some bad flavors can develop.
