sounds like the recipe is off. I make a Wit every 3 weeks or so and have never had an off flavor. Try a brewers best kit or do an AG batch. I think you were short on coriander or bitter orange. The Wit is my "go to" beer while i wait on my others. Give us some brew recipe and method reicpes.
You gonna pull them pistols, or whistle dixie?
