Question: How long is a pot of coffee good for on the warmer?

It starts to taste awful after half an hour or so.

Many years ago I heard about cancer risks from stale coffee. Don't know the details though.

Coffee starts to acidify in 20 minutes. After 30 minutes, fresh coffee is much better. A one or two cup coffee maker sounds right for you. So last limit could be 30 minutes.

Thirty minutes, max.

For my taste any more than an hour and it starts tasting bitter. I shut it off and warm the leftovers in a mug in the microwave.
