Secondly, it is unclear whether IPA is legal to use in this manner in the U.S.
I forgot about the fact that the IPA might not be legal. Seems as though I heard something about it a couple years ago not being legal. It's surprising how many different taps there are available this season and they are basically untested but people are giving something a try that is untested.
