Can't get enough of Ms. Better's Miraculous Foamer?! This one-litre refill bottle is ideal if you find yourself making large quantities of cocktails like Sours. Rather than adding eggs to your cocktail to make them foamy, simply add a third of a dropper Miraculous Foamer – it's suitable for vegans, as well as those who don't fancy their chances cracking eggs! A very useful tool in a bartender's arsenal.
