Great paper. Always happy to see my coffee habit supported by science.
Couple of additional links for those interested.
Newsweek did a lay article on this paper:

And, I wanted to know what we know about L. asaccharolyticus, as years of reading gut biome stuff relating to C. difficile prevention (infection preventionist, now retired), and not having heard of it before. 2018 paper.
