Hmmm, interesting. Several observations, if I may...
1. There's no wheat malt in Buttwiper.
2. If it tastes like Buttwiper then there is a flaw. But this is HB so there are no flaws...

.
3. Let me presume you are fairly new to HBing and your taste buds have not been properly educated.
4. Could be some harsh bitterness on your tongue.
5. Let it age some and the flavor will only get better.
Enjoy it.
