Some breweries including Stone and a couple Japanese breweries were really doing some heavy studies on this to determine which new by-products were produced when yeast work on hop oils. Pretty cool! I've posted here about my experiments with this theory. Bottom line is that I found what Stan speaks of and now always get the beer off the yeast before dry hopping.
