Technically, I think the term whiskey alone refers only to Scotch Whiskey. If you mean which hard liquor has no barley in the brewing process, most (perhaps all) of the liquors ending in whiskey (e.g., bourbon, rye, Irish, corn, etc.) use barley mash in the brewing process. Rum doesn't and normally vodka doesn't use barley in the brewing process.
The ingredients in malt whiskey are basically just barley and water. Barley grains are seeds of the barley plant and are seeped in water until they germinate or sprout.
Barley
Scotch whiskey is distilled from malted barley that may or may not have been smoked over a peat fire.
Whisky is made from fermented grain and there are various types.It can be made with barley, barley malt, rye, malt rye, wheat, or corn.If the grain mix is more than 51% corn, is aged in new charred oak barrels and is bottled at 80 proof (40% ABV), it's Bourbon.
Irish whiskey is made from a fermented mash of malted and unmalted barley, corn, rye, and lesser amounts of other cereal grains
By distilling a fermented mixture of water and a grain, such as barley, corn or rye.
Pure pot still Irish whiskey is similar to a single malt, in that it is not blended with grain whiskey. It is, therefore, a straight whiskey. It is now only made in one distillery in the world - Midleton in Co. Cork. It is made differently to single malt because the mash it is brewed and distilled is made from both malted and unmalted barley. The enzymes in the malted barley effectively stimulate the production of malt in the unmalted barley. There are only a few of these on the market today - Redbreast 12 and Green Spot. The others you get now and again are limited editions.
Seagrams 7 Crown is an American blended whiskey. It's ingredients include corn, rye and barley to name a few.
Whiskey, specifically American rye whiskey, is made from a mash bill that includes a high percentage of rye grain. This gives the whiskey a spicy and flavorful profile compared to whiskey made from other grains like corn or barley.
