if you want to be scientific about it, take the same wort and divide it into aliquots, and pitch each with a different yeast. You'll discover (i) you can make a drinkable beer with bread yeast (ii) yeasts ain't all the same. Different yeasts can impart, as everyone here knows, different flavors.

As for immunologists, what would they know? I remember when all they talked about was T cell repertoires, with not a care or mention of innate immunity, which in many ways is where it's at (yes, I know about smallpox...).

They are prone to studying the side of an elephant with a microscope.

How's that for an inflammatory statement!

Immunology is one of the most complex areas of science, but that doesn't make you a microbiologist.

Time for him to change girlfriends. Not all women are the same, although microbiologically that may be so (apart from the standard fungal etc issues, but we won't go there).

Another puzzling thing about yeast is before the earth was oxygenated, and plants began to flourish where did the yeast find sugar?
It does seem impossible for anything to exist ahead of it's food source. Yeast could have previously been something else that evolved into yeast when sugar became available.

No yeast was yeast before the great oxygenation, they have fossils but scientists believe there was a tiny amount of oxygen being produced on earth as the yeast needed the oxygen to reproduce but I just wonder where their energy source came from?
