I have stumbled upon a bottle of Peanut Lolita in my Grand parents bar. The label looks like it is from the 50's of 60's and still about 90% full. I started researching what this stuff was and eventually came across your post. I hope you are still active on this BourbonEnthusiast site, seeing how this was 6 years ago. I am now trying the "Endinburg Express" drink and I like it very much. I also tried the "Brown Bomber" (.5 oz. Peanut Lolita .5 oz. Creme de Cacao 2 oz. Cream) that was named after the fighter Joe Louis because that was his drink of choice. I think it was good but a little too sweet. It could use a little scotch in that drink also.
You stated you had a few cases of Peanut Lolita. If that is still accurate and you are willing, would it be possible to purchase a bottle pf two from you?
I think, if a some company would bring Peanut Lolita back to life, it might become a hit.
