Jamesons Irish Whiskey

Jamesonis one of the most popular blended Irish Whiskey produced and sold worldwide, by the Irish Distilleries subsidiary of Pernod Ricard. Jameson is on the six main Dublin Whiskeys at the Jameson Distillery Bow St., Jameson is now distilled at the New Midleton Distillery in County Cork -source - Wikipedia

Jameson has an interesting history if we go by the whisky or whiskey first argument, the founder of the distillery John Jameson was originally a lawyer from Alloa, Scotland and previous to establishing the Jameson distillery in Ireland, he married Margaret Haig in 1768, Margaret was the eldest daughter of John Haig, the famous Scottish whisky distiller.

Jameson is produced from a blend of grain whiskey and single pot still whiskey, a single pot still whiskey is a traditional Irish distillation technique of using a mixture of malted and unmalted barley, and Jameson uses the Irish unmalted green barley, all sourced from within a fifty miles of the distillery in Cork.

The barley is dried in a closed kiln fired by natural gas, while anthracite was used previously. This is a distinctive contrast to the use of peat in firing the kiln in Scottish Whisky distillation, which adds a distinctive peat flavour.

Guinness

Gunniess is an Irish dry stout that was the produce of Arthur Guinness's brewery at St. James's Gate Dublin, Ireland in 1759. It is the most successful alcohol brand worldwide, Guinness is brewed in almost 50 countries and sold in over 120 countries. Guinness' unique flavour derives it's uniqueness from malted barley and roasted unmalted barley brews, the older recipe was to blend a portion of aged brew with a freshly brewed beer to give it a sharp lactic acid flavour. On another note, a dry stout is a dark, top-fermented beer, and dry stout is one of the few variants of a stout beer. The original reference of stout was of the strength of the beer, and the same dark brown beer in a later period has also been referred to as a porter, and the stronger verities were called "stout porter" and thus the history of a stout and a porter is pretty intertwined. Although today, a stout is strictly a dark beer, strength is not a qualification of a stout anymore. Top fermenting is one of the different beer brewing techniques, in which, the yeast is applied to the top of the wort ( the sugary extract of the malts and other ingredients that the yeast will ferment into a beer ) at a much higher temperature.

Mcguinness Melon Liqueur is a bright green coloured melon liqueur, with a gentle melon flavour, however this Melon Liqueur is not widely available in USA.
