In the November/December issue of Zymurgy there is an article entitled Decoction: Worth The Effort? and I agree with the results based on the decoctions I have done. On page 54 the score averages are given for infusion, decoction, double decoction, and triple decoction. It was no surprise to me to see the decoction scored the highest, the infusion was next and the rest trailed. What I found when I was brewing often and entering competitions was decoction added at best a point or two to the score. It basically improved the complexity, but not much, ~2%. In the Zymurgy article the difference between decoction and infusion was 1.6% with the decoction taking the nod. For most beers it simply isn’t worth the time and effort.
