Are you referring to a witbier as well?
I wouldn't dare consider myself an expert on witbiers, Mr. Guy Who Lives in Belgium.
I should clarify my statements by saying:
A) I don't trust an average judge's ability to be able to differentiate ingredients under just about any circumstances;
B) I seriously doubt that even a National or Master level judge could taste a difference in malted vs. unmalted wheat when covered up in an IPA under a buttload of hops; and
C) I think in a low hopped witbier, a good judge might be able to taste a difference in malted vs. unmalted, but am uncertain.
These opinions may not reflect those of any others or that of my place of employment.
