As it turns out, Bear Republic is based in Sonoma County, California. In the midst of all those vines and wineries, some people people got together and thought 'Gee, I should make some beer that's really hoppy'. And they do a really good job!
Racer 5 (V?) is one of my absolute favorite IPA's. It's amazing, has a wonderful balance, and is a little 'unfinished' in its own way, which is really endearing to me.
Racer X (today's beer) has the exact same essence as its younger sibling, but turned up to 11. Actually, I shouldn't really say that, because I think there a Racer XV, and I want to make sure I have an adequate expression for that review. Let's just tentatively say they turned it up to 7 & 2/3rds. Cool.
Delicious beer. Looks pretty cool as well. Yum!
