What is Irish Whiskey?

Irish Whiskey, as the name “Irish” suggests, is a whiskey made in and originated in Ireland. Irish Whiskey was launched in the United States in the early 18th century by certain Irish immigrants.

Since then, it has become a famous whiskey not just in the United States but worldwide, although it had a certain period of decline in the 19th century. However, Irish Whiskey has gained immense popularity as the fastest-growing whiskey since 1990.

Irish Whiskey is prepared from unmalted and raw barley. However, an important aspect is that barley drying in covered kilns keeps the natural flavour of barley intact, which eventually translates into an excellent fine-tasting whiskey.

Irish Whiskey is commonly matured for a minimum of three years. The pot apparatus used in distillation is thrice the average size of usual copper pots.

Irish Whiskey is triple distilled. This additional distillation is essential in producing a smooth and light flavour for the whiskey.

Oak casks, ex-bourbon, or Sherry casks may also be used to prepare Irish Whiskey, which leads to classic sweet and spicy flavours.

Irish Whiskey‘s use of unmalted barley in the preparation has a historical connotation. There seems to be a specific tax on malt, which used to exist in Ireland.

Therefore, whiskey producers used unmalted barley in Irish Whiskey. Though the malt tax was later abolished, the producers continued using unmalted barley in the preparation.

Irish Whiskey production is regulated in Ireland through the Irish Whiskey Act 1980, which specifies the essential requirement for whiskey preparation, distillation, and maturing. Also, Irish Whiskey is considered a  protected European Geographical Indication (GI) under Regulation (EC) No 110/2008.

There are multiple types of Irish Whiskey, such as single malt Irish Whiskey, single pot still whiskey, grain whiskey and blended whiskey.  Certain Irish Whiskeys may carry an age statement.

These types of whiskeys are considered reasonable and cheap compared to certain other whiskeys.
