What Is Irish Whiskey?
The Irish, along with the Scottish, were one of the early producers of whiskey. Among Irish whiskey, the word is spelled with and "e". This was purely for market differentiation from Scottish Whisky. Unlike the Scottish, Irish whiskey is not made with the use of peat moss.
Much of the distillation of Irish whiskey was distilled in a pot still. Pot stilled whiskey is at least 30% unmalted barley, at least 30% malted barley, and the remainder is unmalted cereal grain. Whereas grain whiskey is a minimum of 30% of malted barely distilled in a column still.
Originally the column still was referred as a Coffey Still. The Coffey Still was invented by Aeneas Coffey. The column still is a continuous distillation and more efficient than the pot still.
