Old Bushmills Distillery operates from County Antrim in Northern Ireland, producing Irish whiskey in a region with deep distilling traditions. The distillery creates both blended and single malt expressions, representing two fundamental approaches to Irish whiskey production.

Irish whiskey from this region typically undergoes triple distillation, a process that contributes to a characteristically smooth and approachable profile. The practice of triple distillation, combined with Ireland's temperate climate for maturation, often yields whiskeys with lighter, more delicate characteristics compared to their Scottish counterparts. The production methods emphasize clean distillation and careful barrel selection.

The distillery's current range includes their Original blend, which combines grain and malt whiskeys, alongside a 10-year-old single malt expression. The single malt represents whiskey produced entirely from malted barley at a single distillery, while the blended offering incorporates both malt and grain spirits to create a different flavor profile and accessibility.
