Made to a recipe formulated in the 1820s, Melbourne-based company Sin-ko-nah has introduced a tonic syrup that will invigorate your G&Ts (amongst other things). The syrup is made from real cinchona bark – the natural source of quinine – which is touted to treat a raft of ailments from gastric disorders and fevers, to cramps and the flu. But what really gets our motor going is the authentic, inimitable flavour profile, which makes it delicious with or without an accompaniment. While the syrup is typically blended with gin and soda, it can also be used to flavour cocktails, and is surprisingly tasty drizzled over vanilla ice cream, or used to dress meats and salads.

One 500ml bottle of syrup will set you back $45 and make around 6.25 litres of tantalising tonic water, while a dinky 200ml bottle is priced at $24 and will yield around 2.5 litres. Order yourself a bottle online (free postage!), or swing by one of Brisbane’s stockists, Cru Bar and Cellar or The Standard Market Company.
