How did Maxwell House coffee get to be “good to the last drop”?

The phrase belongs to President Theodore Roosevelt, who, while visiting Andrew Jackson’s home, the Hermitage, in Nashville, Tennessee, drank a cup of Maxwell House coffee and was offered a refill.

He is said to have replied, “Will I have another? Delighted! It’s good to the last drop!”

By the way, there actually was a Maxwell House.

A luxury hotel in Nashville, Maxwell House was the place where, in the 1880s, the coffee was first served.
