Gum syrup (aka gomme syrup, gomme) is a classic pre-Prohibition cocktail ingredient - sugar syrup thickened with gum arabic – a tasteless powerful natural thickener from the bark of African acacia trees. While gum syrup fell out of favor post Prohibition, it is slowly starting to come back into fashion thanks to the recent resurgence in cocktail culture.
What makes gum syrup so special is that when it’s added to cocktails it not only sweetens, but also increases viscosity. The result is a luxuriously silky texture that really ties the drink together.
This gum syrup is a potent 2:1 strength version, so each bottle will make many cocktails (Liber & Co says you’ll get about 30 Old Fashioneds)
Though gum syrup is most commonly used in cocktails, it’s also a better alternative to plain simple syrup in non-alcoholic iced beverages like iced tea or iced coffee.
