Perhaps understanding IBU's would have helped you sir.

We have all seen the number on the back of the bottle or the
side of the can. For example, the Sly Fox 360 IPA that I have sitting next to
me has 70 IBUs. Most people don’t even notice the number or know what it means.
The short answer is that IBU stands for International Bitterness Units and
is a scale that measures the amount of hops in beer. The long answer is that IBUs is a complicated number that gives you a
rough idea of how hoppy a beer is. I say a rough idea because 2 beers with the
same amount of IBUs can taste different from one another.
How can beers with the same IBUs have different hop tastes
from one another? I’m glad you asked. The obvious answer is that they use
different hops but that answer is just one reason. Another reason is that the
more malted barley added to the beer, the more the hops can hide. If you were
to look at a West Coast IPA and compare it to an English IPA, they could use
the same hops and have the same IBUs but the West Coast would taste like it was
miles apart from the English. English and Belgian IPAs tend to be maltier so
the IBUs can be less pronounced. American IPAs, especially West Coast IPAs,
showcase the hops so typically they have a lighter malt base.
Getting back to the hops, there are many different varieties
of hops grown all over the world. Hops are similar to grapes that they develop
a terroir based on where they grow. There are the “Noble” hops of Europe, the
dank and citrusy hops of the Pacific Northwest, and the hard to get New Zealand
hops. They are developing new hops every year. Hops grown on the East coast may
vary significantly from the West coast even though they are the same
variety.
Not every beer has a pronounced hop flavor. Most lagers,
pilsners, and wheat beers have low IBUs. Many beers actually fall within the
range of 20 to 50 IBUs. I always use the IBU number as one factor when looking
at a beer. I look at the location of the brewery, the style, the ABV, the IBUs.
Just by looking at those things, you can build a rough profile of what the beer
might taste like but it is always good to do your homework too. There are so
many factors that make up the hop profile of a beer. I could go on for days
just about flavoring versus bittering hops and alpha acids but I will save that
for another post.
So how do brewers decide how hoppy to make a beer? Every
beer style has guidelines that provide framework for each style. That framework
really only matters for competitions but most brewers try to make sure their
beers fall within the guidelines. I mean who doesn't like to win an award?
There is a link at the bottom of the post to the BJCP style guide if you want
to know more about your favorite style. We keep a copy of it printed out on the
counter at the store if you ever want to take a peak.
Like I always say, the only way to find out if you like a
beer is to try it. If you are new to really hoppy beers, you can ease yourself
into it by starting with a lower IBU beer and working your way up. Just keep in
mind that your mouth can on taste up to 120 IBUs so anything over that number
is just a waste of hops. That being said I would still like to try Canada's
Flying Monkeys Craft Brewery Alpha-fornication, an Imperial/Double IPA that clocks in
at 2500 IBUs and 13.3% ABV. If anyone is going to Ontario any time soon, grab a
bottle for me if you see it!
