From the Wikipedia page for Liebeck v. McDonald's (the infamous hot coffee case):
Since Liebeck, McDonald's has not reduced the service temperature of its coffee. McDonald's policy today is to serve coffee at 80–90 °C (176–194 °F), relying on more sternly worded warnings on cups made of rigid foam to avoid future liability, though it continues to face lawsuits over hot coffee. The Specialty Coffee Association of America supports improved packaging methods rather than lowering the temperature at which coffee is served. The association has successfully aided the defense of subsequent coffee burn cases. Similarly, as of 2004, Starbucks sells coffee at 175–185 °F (79–85 °C), and the executive director of the Specialty Coffee Association of America reported that the standard serving temperature is 160–185 °F (71–85 °C).
The accompanying citations in the article are either dead or don't contain a reliable citation for their own claim, and none of the major coffee sellers (McDonalds, Starbucks, etc.) nor the industry groups seem to have the number easily accessible.
