Apparantly, "good to the last drop" was also attributed to TDR by Maxwell House who used his likeness for decades. Sad note: One of his sons shot and killed a giant panda.

Theodore Roosevelt was famously possessed of such formidable natural energy that he was known at Harvard as a “locomotive in human pants.” But something else might have fueled his vigor. As a sickly child, he was given strong cups of coffee—along with puffs of cigar—to ease his terrible asthma attacks. As president, he was so devoted to the stuff that his huge custom coffee cup was described by one of his sons as “more in nature of a bathtub.”
So perhaps it’s not a jolt to learn that his sons Kermit, Ted and Archie, along with daughter Ethel, her husband, and TR’s cousin Philip, opened a chain of coffeehouses in New York City. Long before goateed baristas pulled single-origin shots in Brooklyn, and many decades before Brooklyn native and Starbucks mogul Howard Schultz got the idea to bring European coffee culture stateside, the Brazilian Coffee House, in Midtown Manhattan, was intended to bring quality coffee and a sociable public space to harried New Yorkers.
