        Hi Baker,

        Yes, your correct.  Boiling the potatos will kill off any microbes on there skin.  Using just the waters containing nutrients and some sugars and starches open to the air will cause airborne wild yeasts to infect it.

        Not really Baker, both bread yeast and wine yeasts are mainly from the genus Saccharomyces  and species  cerevisiae  within the species Saccharomyces cerevisiae (check it out in Wikipedia), there are over 1500 strains of this yeast that have been cultured for making bread yeast, wine yeast, whiskey yeast, ale yeasts etc., etc..  These strains were originally cultivated from wild yeasts that have been found on the skins of fruit (or grains) which have formed a symbiotic relationship with the fruit or grain.  The other main species of yeast for making wines (mainly champagnes) is  Saccharomyces bayanus  a more alcohol tolerant species of yeast.   One can make bread from a strain of wine yeast and make wine from a bread yeast.

        Again this depends on how good or bad that wild yeast strain could be..

        Correct again Baker:     "Common media used for the cultivation of yeasts include; potato dextrose agar (PDA) or potato dextrose broth,"

        Corrct again.

        Yes, due to the symbiotic relationship, the wild yeasts on the skin of each varietal grape was used to start the fermentation.  Eventually, these were cultivated into various red and white wine,  grape specific strains.

        Correct again - see above.

        Yes - the worst ones being vinegar producing bacteria - acetic acid bacteria.
