In the spelling, it differs in an 'E' for whiskey! And even so, it has a few unique selling points to offer. It is often still distilled 3 times and only in Ireland is there a single pot still.
Let's start with a special variety of Irish whiskey that actually exists exclusively in Ireland! Malted and unmalted barley is distilled in a pot still. Other types of grain may also be used in addition. After a malt tax was introduced, resourceful distillers switched to this method to keep costs down. If the whiskey comes from a single distillery, it may be called Single Pot Still.
The "best" Irish whiskey is made in the same way as Scotch: Single malt Irish whiskey is made exclusively from malted barley and distilled in copper pot stills. It must be matured in wooden barrels for at least three years and must contain an alcohol content of at least 40%.
Grain whiskey also owes its origin to the increase in the tax on malt. Many distillers in Ireland replaced parts of the malt with other grains such as corn, wheat and unmalted barley. This led to the rise of grain whiskey. It is usually distilled in column stills. This continuous distillation process also contributes to cost-saving production.
Here, too, the 'single' stands for a single distillery, so this whiskey is indeed made from different types of grain, but from a single distillery!
The higher the proportion of malt whiskey in the blend, the better the whiskey!contains and grain .
