That’s true, that really is the perception.
But it’s one I really don’t totally understand or agree with since some of the very best brews I’ve had over the years have been single hop brews, or ones made with a combination of only two varieties.
After trying just about every variety under the sun (which is ongoing, since new varieties are beeing introduced quite frequently), I found that my favorites are still two very old traditional varieties.
Opinions do differ widely on this subject, but I’ve found beers with overly complicated hop bills and hopping schedules to quite often be a muddle, rather than exhibiting the ‘complexity’ that is often touted. Many homebrewers go for complicated and oftenn random combinations merely because ‘they can’. The sheer variety of hops available these days is unprecedented compared to the early 1970s when I did my first brews (when the choice was either cheesy smelly generic compressed bricks, or, by the mid/late 70s, Cascade pellets.)
I think it’s just one of those topics that is dependent upon one’s own personal tastes and perception.
But I do totally agree that doing a series of single hop brews (in a consistent wort from a relatively simple grain bill) is the best way to let your own senses experience what a given hop variety offers. Remember that your perception will very often be different from what you read in the forums, since everyone’s tastebuds are unique. And (to me anyway) this hobby is very much above all else about brewing to ones personal tastes.
