Yes, yeast is one of the variables. The others are the types of malt used, the water and the quantity of hops/spices/preservatives.
No. Yeasts make beer - a completely different micro-organism.
There are many different yeasts. The yeast used to make bread, beer, wine, and distilled spirits is named Saccharomyces Cerevesiae.
There are thousands of different types of beer. The variation of hops, grains and yeasts used to make it lead to variations. There are thousands of small breweries each making their own types of beer. And the major categories would include:BeerAleIPAStoutPorterDouble bocks
You can rule out most yeasts like red star or fleischmanns. If you want a really strange beer mix a real beer yeast 2:1 with Fleischmanns. Make sure you vent the mix well to avoid a ceiling load of suds.Try Ebber's or the Black Labelled Carneys for Weiss beer, anything German for lager.Make sure the yeast is guaranteed against infection, and buy from a legit place.
It'll make the taste have a metal taste to it, it will be gross.
Lots of miller light beer
Yes, it is indeed possible to make wines with naturally occurring yeasts.
It means you do things or buy things you cant afford. If you make 20,000 a year and buy a 400,000 house, you have a "champagne taste with a beer budget."
Great Taste
They generally do. You can taste the alcohol. Now, if you mean alcoholic beer versus "non-alcoholic" (still contains some alcohol, but it would take at least 5-6 drinks to equal an ordinary beer), the "non-alcoholic" beer may actually taste even more bitter. Without as much alcohol, something has to be added to make up for the difference in taste, so they may add more hops to the mix.
There is no way to make a cow that gives beer out of it's udder, instead of milk. If beer did come out of a cow's udder, it would probably taste like urine, the other liquid that comes out of a cow.
Yeast. Yeast is used to make alcoholic beverages through a process called fermentation. Essentially, yeast in anaerobic conditions consume sugars and produce ethanol (alcohol) and carbon dioxide.
