What kind of Brett character were you picking up? Was if barnyard/leather/funk, or was it cherry pie/pineapple? I could see how some of the newer hop varieties might hint at some of the fruitier Brett aromas, especially when coupled with a dry finish. But if you're picking up sweaty saddle blanket, then it's likely an infection.
Of course, you could brew a 100% Brett Session IPA, but that's another story.
