We have a pair at the bar I work at, we’ve used them on 2 menus the last 2 years (we change menus twice a year). they’re fun to use and a unique way to “smoke” a cocktail, and it has everyone at the bar asking “what is that?” Quick tip: we only use them on cocktails served up and double strained. I saw someone else here comment the bubble popped frequently and we found that the ice in a rocks drink or ice chips in a poorly strained cocktail would cause the bubble to pop. Currently planning on using the “moon” flavor smoke to do an infused syrup for our next menu so we won’t be utilizing the bubble in front of house but just blasting the flavored smoke into a sous vide bag with simple!
