Yeast impact the flavour and aroma of beer more than you might think. The flavour and aroma of beer is very complex,
being derived from a vast array of components that arise from a number of sources. Not only do malt, hops, and water
have an impact on flavour, so does the synthesis of yeast, which forms byproducts during fermentation and maturation. The most notable of these
byproducts are, of course, ethanol (alcohol) and carbon dioxide (CO2); but in addition, a large number of other flavour compounds are produced such as:
acetaldehyde (green apple aroma)
diacetyl (taste or aroma of buttery, butterscotch)
dimethyl sulfide (DMS) (taste or aroma of sweet corn, cooked veggies)
clove (spicy character reminiscent of cloves)
fruity / estery (flavour and aroma of bananas, strawberries, apples, or other fruit)
