The exact phrases probally come from all the people writing on sites about how to brew beer. (it kinda hard to write about this topic without saying "beer brewed .....")
"Beer brewed in a pumpkin" is a funny one
past tense holds it back alot in my opinion, but i am surprised its not reg before you since there is a zillion hobbist beer brewers combined with domainers that will reg anything.
looks like its never been reg before, plus ALL extentions are available, which general means its not too desirable.
