Why does my beer taste yeasty?
Yeasty Off Flavors in Beer Not surprisingly the main cause of yeasty beer is simply that the beer is too young. Beer goes through changes as it matures including the mopping up of off flavors like diacetyl and also a critical process called flocculation where the yeast slowly falls out of the beer.
Why is my beer so acidic?
Abnormally high acidity can be an indication of bacterial infection of wort and/or beer. Microbial contamination issues (lactobacillus strains, for example) leading to abnormal acidity are usually perceived by the brewer or consumer before any testing would show the defect.
What happens when beer oxidizes?
One of several problems that can happen in beer brewing is oxidation. Oxidation in homebrew is a chemical process that can destabilize it and cause stale, off-flavors.

How do you reduce acidity in beer?
To raise or lower the pH of a Mash , additions of calcium carbonate (to raise pH) or calcium sulfate / calcium chloride (to lower pH) are recommended. If these are not available, or if you are brewing with very soft water, then the addition of phosphoric acid can accomplish acidification of the mash.
Why does my homebrew beer taste sour?

What gives beer its flavor?
Grains, yeast, hops all add specific flavors to beer, but when used incorrectly they can cause undesirable or unexpected flavors. Certain yeast strains are known to sour a beer.
