So we are drinking Yeast pee & crap?

If you ferment in glass you can literally sit there and watch them peeing and farting. People say they float around, but I've seen them swim, like they have an objective in mind. They don't just aimlessly float, they are smart little buggers. Sometime people think they messed up a batch only to find out later, the yeast outsmarted them and fixed their mistake when they weren't looking.

I don't know the answer to the best yeast to use, I'm just learning about that myself. Depends on the taste you are going for, is what I'm told, and the fresher the yeast, the better.
 
I love the reaction on peoples faces when describing fermentation and ending it all with, "So basically alcohol is yeast crap"

It's an oversimplification, but for some reasson people get that when everything else flies over their head.
 
It's an oversimplification

Yeast has a huge job of proceessing sugars and other fermentables into something we can use... alcohol. How exactly do they do it? Wouldn't mankind love to know so we can replace them with tools and equipment, or chemicals. Ah HA, but we can't, they provide a service beyond our comprehension.
 
You have to remember that yeast pee & farts are higher on the ladder than ours. They pee rose water & fart cologne by comparison. On the flip side,Matching the yeast to the style of brew is the easiest way to look at it. Midwest is pretty good for denoting such things. also,what esters & phenols the particular yeast puts out.

so I should quit peeing & farting in bottles & giving them to coworkers?
 
Luckly, they dump alcohol and CO2. Other wee beasties give off real nasty stuff. Some make lactic acid which is literally cutting the cheese.

Glycolysis is the grand daddy of all respiration! A evolutionary relic! God bless it!
 
I suppose, technically, yeast neither "pee" nor "crap."

They just do what we do -

Aerobic respiration just like us - producing CO2 as a biproduct.
Anaerobic respiration producing alcohol (rather than lactic acid like us).

Since we do not classify our CO2 production or our lactic acid production as either pee or crap . . . . then I suppose their's is not either.

Although, I suppose maybe some of the other flavors/off flavors could be "waste products"????
