Every microbrewer seems to have some sort of excessively hopped beer. Just consider the names of some beers I've tried recently (and these are just the ones with the word "hop" in their name!):
- Hops Explosion Pale Ale
- Hoptical Illusion
- Hoptimus Prime Double IPA
- Hops Wallop Ale
- Hop Stoopid Ale
My verdict: the 60-Minute is pretty good, the 90-Minute is definitely at the upper end of tolerance, and the 120-Minute is undrinkable.
The taste of beer is really about two things (in my uneducated opinion): the type(s) of malt and hops used, and the balance between these ingredients. (A third variable is the type of yeast and fermenting process.) There's a tremendous variation available within these parameters, but the key is still balance: tip the scales too far one way or the other and you get bland crap (think any major brewer) or overly bitter crap. It seems that in an attempt to gain attention and market share in a very competitive (and difficult to succeed in) business, brewers are appealing to that natural male machismo: "C'mon. If you're a man, you can handle the bitterness. Suck it up!"
