My understanding is that black coffee and tea are OK, but adding sugar or milk/cream is out.
I have heard from several podcasts and other sources devoted to IF (and time-restricted eating) that black coffee does technically break your fast, particularly in regards to autophagy. This is because the body has to break down and digest the compounds in coffee, and this requires the release of digestive enzymes, etc. However, from a blood sugar/insulin standpoint, I think black coffee is not considered a problem since no insulin (or very, very little) is secreted.
Check out this video for a brief discussion. They discuss the coffee issue in some depth starting around 07:18.
