Tag: Oxidized coffee

While a cup of plain black coffee can technically remain safe to drink for up to 12-24 hours at room temperature, its peak flavor diminishes significantly within 30 minutes due to oxidation. So, is coffee good after 8 hours? The answer depends heavily on whether you prioritize safety over flavor and if any milk or creamer was added.

While black coffee left at room temperature for up to 12 hours is generally considered safe to drink from a bacterial standpoint, its flavor deteriorates rapidly due to oxidation. This brings many to ask: **Is oxidized coffee bad for you?** The answer is more complex than a simple 'yes' or 'no' and involves understanding the difference between stale flavor and actual health risks.
