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.
Yeast is used in winemaking, where it converts the sugars present in grape juice (must) into ethanol. Yeast is normally already present on grape skins. Fermentation can be done with this endogenous wild yeast, but this procedure gives unpredictable results, which depend upon the exact types of yeast species present.ertain strains of some species of yeasts produce proteins called yeast killer toxins that allow them to eliminate competing strains. (See main article on killer yeast .) This can cause problems for winemaking but could potentially also be used to advantage by using killer toxin-producing strains to make the wine.
