Metallic taste

[homebrewnewbie]

The past two batches I've made have had a metallic/tangy taste, and it's unbearable. What could cause that?

in short two things;
1) metal
2) overcarbing

I brewed a RIS a few years ago and when I didnt have a fermentation chamber yet and the yeast got out of control. I think high levels of fusel alcohols and give a hot metal like taste to the beer as well.
