There are no wrong answers...

One of the most interesting aspects of evaluating beers is that no two people are going to get the same thing out of the same beer, which is why judges are paired or grouped in competitions.  All of our noses and palates are sensitive (or insensitive) to certain aromas or flavors.  For example, I had my wife try a couple of the beers I was evaluating for my current tasting class.  We apparently were getting different fruity esters from an English bitter.  She was getting more of an apple aroma, where I was getting more of a lemony citrus aroma. Another interesting comparison was the Wee Heavy.  She described it as acrid where it came across as smoky and peaty to me.  It goes to show that there are ultimately no single right answers.  It's all about what you get out of it, except where the exam is concerned, that is.  ;)
