In 1780, the Scottish businessman John Jameson purchased the Bow Street Distillery in Dublin. It was not long before his chief brand, Jameson Irish Whiskey, would become internationally popular. The Bow Street distillery was previously producing around 30,000 gallons annually but by the turn of the nineteenth century the distillery was producing over a million gallons. John Jameson was keen to produce the best product possible, sourcing the finest ingredients. Furthermore, John triple distilled his product when most others were double distilled; he believed this produced a smoother product. During the early nineteenth century, John Jameson’s son, John II, expanded the facilities which were, by this time, among the largest in Ireland. John II’s son John III further expanded the brand and when his son John IV came to power at the helm of the Jameson brand, he found himself in charge of a global brand. Today, Jameson is the best selling Irish whiskey in the world.
