Esters generate the fruity aromas found in beers. They tend to be more present in top fermented ales, and less so in bottom fermented lagers. There's some debate as to if this is due to the yeast strain or possibly fermentation temperature. The most significant esters you'll notice in beer are isoamyl acetate, which gives a beer the banana like aroma that MAKES a German wheat, ethyl acetate which is lightly fruity and solvent like, ethyl caprylate which will bring apples to mind, ethyl caproate which is also appley with a touch of aniseed, and phenylethyl acetate which brings roses and/or honey.
