JUst read very good article in recent BREWSMITH newsletter on yeasts
What exactly is the role of esters in brewing? I know its out there, but I am getting lazy in my old age (besides, Larry, Nosy, Mad Ferm, et al will give a concise definitive answer)
Ale yeasts ferment in the range 10-25C and produce beers high in esters and often lower in attenuation, both distinctive characteristic of ales. Ale yeast strains are often mixed together to aid in attenuation and flocculation. Lagers ferment in the range from 7-15C and produce a cleaner beer with lower esters.
