Yeasts are a unicellular [[fungi]], and grow in lots of different places. Yeasts are found on wide variety of plant leaves and flowers, in soil, in water and in your gut. They are partly responsible for your body odour, and yes, thrush was most certainly period (''Candida albicans'' causes that). They're used as a raising agent in [[cooking]] and it makes your [[brew]] [[ferment]] to produce ethanol. Yeasts are also very good for you, and are rich in folic acid (good for pregnant women), vitamin B and niacin.

''Saccharomyces cerevisiae'' is the species of yeast most commonly used in your [[brewing]] and [[bread]] baking. They ferment [[rice]], [[wheat]], [[corn]] and [[barley]] [[sugar]]s. The yeasts that ferment your wine are commonly found on the plants in the [[vineyard]] anyway. It's believed that no one used to intentionally used to add yeast in the goode olde days, but because grows everywhere it would breed in the cracks of the brewing barrels and other brewing equipment. Yeasts don't particularly like being heated above about 40C and will tend to start to die at about this temperature.
