We were in Colorado recently for our nephew's graduation from high school. Suffice to say, we did not have much time for cocktail adventures due to family commitments, but we did manage one trip to a couple of places in Boulder. Our favorite by far was the West End Tavern, which was recommended by a friend of ours.
While there, we saw this cool gadget on their back bar, holding fresh basil. The bartenders said it extends the life of the basil for several days - basil is a notoriously short-lived herb, but is also a great addition to certain cocktails.
This gadget is called the "Herb Savor" and is made by a company called Prepara. They have some other cool stuff on their website, especially this "Power Plant".
I think I've got some ordering to do....
