Alexander Walker had introduced the brand’s signature square bottle in 1860. This meant more bottles fitting the same space and fewer broken bottles. The other identifying characteristic of the Johnnie Walker bottle was – and still is – the label, which, since that year, is applied at an angle of 24 degrees upwards left to right and allows text to be made larger and more visible. This also allowed consumers to identify it at a distance. One major factor in his favour was the arrival of a railway in Kilmarnock, carrying goods to merchant ships travelling the world. Thanks to Alec’s business acumen, sales of Walker’s Kilmarnock reached 100,000 gallons (450,000 litres) per year by 1862.
