What product in 1907 had the slogan 'Good to the Last Drop'? Who coined the phrase?

Legend has it that on a visit to Nashville in 1907, President Teddy Roosevelt declared that Maxwell House coffee was "good to the last drop." One hundred years after President Roosevelt's declaration, that familiar slogan remains the brand's promise to its customers.

There is reasonable doubt that Roosevelt ever actually said this, but Maxwell House themselves claimed he did and used it in ads.

The subject of this post is a peculiar association of Maxwell House with Theodore "Teddy" Roosevelt. Remember the Maxwell House slogan, Good to the Last Drop? Of course you do, who could forget? Well, it is often claimed that Teddy Roosevelt, in 1907, coined the slogan after the coffee was served to him at the Hermitage, a famous Nashville resort that was originally Andrew Jackson's home.

Pendergrast, in his book, doubts that Roosevelt ever said those words. However, the company itself claimed differently in advertisements.

Roosevelt gave the Hermitage ladies his backing for a federal appropriation for their project to restore the Jackson mansion. The ladies gave him a cup of coffee. A marketing legend was born: The hostess asked him if he would have another cup of Maxwell House Coffee. "Will I have another? Delighted! It's good to the last drop!"

President Theodore Roosevelt said it in 1907 to Joel Clark about coffee. Coca-Cola used it in 1908 and Maxwell House patented/trademarked it in 1926.
