Hey fellow coffee friends. As it is hot season here in Germany I actually enjoy my coffee cold, so I set up a cold brew every two or three days.

Well, when I got into that habit I got the hint to never let the brew touch metal as it alters the taste to the worse, it gets sour and „off“.

Now my question is, is this a myth? I see cold brew makers which would be way more convenient than my measurement cup/cotton filter method, but all of them have some kind of metal filter, so I am very reluctant to buy one of those. Has anyone insights and our experience on this topic?

My cold brew maker use a metallic filter, but I also bought a pack of paper filters to try out. I haven't noticed a sour or off flavor when using the metal filter, and use it almost exclusively, fwiw.

How do you use the paper filters? I have on of those but apparently while in a rush one day I threw out the metal filter with the grinds and can’t get a replacement here in the uk.
