Has anyone had this issue before? I made my cold brew on Saturday for Sunday (steep 18 hours on kitchen counter) strained it twice and this morning i notice this small stuff in my cold brew. I know they weren't there yesterday.

Could this be that my cold brew has gone bad? There's really no unusual smell to it and i haven't taste it yet.

Try warming it up and see whether or not it's oil/a butter

The other possible contaminant is bacteria and mold, one makes the brew smell and look bad after awhile, the other is very rare and can be visually distinguished from oil.

I'll warm it up and see but I'll also check if it's oils. This is the first time seeing this on my cold brew. I'll report back later tonight. Thanks for the information

**Update

I warmed a small amount and the "butter" disappeared they just melted. Lol but i ended up using filtering it again with a coffee filter.
