That sometimes happens to me too. I don’t know why though.

Really interesting reading the comments to this!

maybe get a check up – there are all sorts of neurological things, and reactions to medications that can have this reaction… good luck

Sounds like a descaling issue..unless you were pregnant?

you have to descale it. i bought descaling solution from target and it was hard to find as it was in the kitchen utensil section
follow instructions and you’ll be right. my coffee machine has a light that tells you when you have to do it

I have the same problem sometimes. I just clean and run hot water through it. 🙂

What did you end up doing?

there are some good comments here

I love my coffee, id hate if that happened to me!

sounds like the machine needs cleaned or descaled

what did you end up using?

What did you end up doing to get rid of the metallic taste?

Try descaling the machine and also check the water

Did it taste better after cleaning the machine?

Thw machine might need a good cleaning.

Did you end up finding out why?

Are you pregnant? The reason I am asking this is because when my wife was pregnant and towards the end of her pregnancy a lot of things she was eating and drinking started tasting like a metallic taste and it was her hormones going haywire. It stopped about a couple of weeks after she gave birth to her twins.

Another thought, do you store your coffee in a metal container?

Hope you found a solution to this

Hmmmm…. Could you be pregnant? Metallic tasting coffee has been the first sign for both of my pregnancies!
