Where do you store your coffee? I had a similar problem when I used to store my coffee on a shelf above my toaster and kettle. I think the heat rising from these appliances changed the flavour of my coffee. I now keep it in a cool dark spot and the flavour isn’t effected.

some good answers here ill be keeping this in mind if this ever happens to me.

This happened to me with tea too. I cleaned the kettle by soaking half a lemon in it and metallic taste disappeared!

Maybe you need to clean out the filters

Have you found an answer? If not maybe call the manufacturer?

Sounds like your machine needs a lime descale. You can actually find some samples of descalers online if you want to try it before buying it.

Interested to find an answer too

Descale and thorough clean should fix.

You need to discale your coffee machine.

If you haven’t used it in a while it may need a really big clean, I would pull it all apart and clean it thoroughly

try cleaning the machine out, vinegar and lemon works wonders

needs to do some descaling

maybe your detoxing?

I would try a clean and descale of the machine and kettle first.

I had that once from a hot chocolate. Turned out I had a hole in my tooth and the drink being hot was hitting a nerve. Weird

kettle… i would clean it or go buy a new one if buying a new one make sure you to boil water in it first than empty before your first use

or if you use raw sugar sometimes it tastes like that or tinned cvoffee

You can descale by mixing equal parts white vinegar and water and running that through the machine until it’s nice and clear. Then run at least 2 cups clean fresh water through to rinse

How do I rescale
