Hefeweizen - Metallic tastes

[MWM777]

Just cracked open my first bottle of Hefeweizen from my very first brew. While it has the typical banana nose, I'm detecting a strong "tinny" or "metallic" flavor and scent. What's the typical (if any) cause of this undesired flavor?



Brewer's Best "Weizenbier" kit:



6.6lbs German Wheat LME

1.5 oz Hallertau (40 mins, 15 mins)

WL 300 liquid yeast (70° pitch temp, 66-68° fermentation temp)



Anyone else have this issue?

What kind of pot did you use for your boil (aluminum, stainless)?

5 gallon stainless steel pot. I clean it with soap and "Bar Keeper's Friend" after every brew.
