The quest to alchemise the perfect gin and tonic is one that many people have embarked upon. In fact, three friends in Austin, Texas, dedicated an entire summer to brewing a concentrated tonic from scratch. Once they had perfected their recipe using using raw ripe citrus, fresh-cut botanicals and hand-cracked spices, they founded the artisan company, Liber & Co. Their range of beverage accompaniments now includes a Spiced Tonic Syrup and two flavours of ‘shrub’ (an antiquated method of liquid fruit preservation), including Texas Grapefruit.
