what causes Metalic taste

[Leukass]

i gave a few friends a couple of my beers to try and one of they came back to me that it has a metalic finish. What causes this?

Metallic flavors in beer is likely the result of high iron content in water. Or it could be that you used mild steel, aluminium, or cast iron in your brew process.

I use the bayou classic 16gal stainless pots. So I am pretty sure they are full stainless and not coated. I guess I need to get my water tested.

No aluminum is fine- but make sure to boil water in it first to get a nice oxide layer on it and keep it that way (not super shiny inside). Then it's fine to use.

Are you kegging or bottling your beer?

Kegging and I do the force carb at 30 for 48 hours.

Some people might perceive excessive carbonic 'bite' as metallic which could come from force carbing. Maybe try a batch without force carbing ans see if there is a flavor difference.

I bet it's the burst carbing that's giving you that taste. Have a look through this that thread I posted recently.

Had a metallic taste to my brown ale and it's starting to go away.
