The rule
Four styles that matter at home
Bourbon
Corn · new oak
Rye
Spice · dry
Scotch
Malt · peat?
Irish
Soft · pot still
Bourbon is at least 51% corn, aged in new charred oak. Vanilla, caramel, corn sweetness. It is the usual home pour for Old Fashioneds and whiskey sours. Buffalo Trace or Maker’s Mark — or another solid ~45% bourbon you like neat — will do that job. Maker’s is a little softer (wheat in the mash). Both mix. Bourbon may be made anywhere in the United States. Kentucky is tradition, not a legal requirement.
Rye is at least 51% rye grain. Pepper, baking spice, a drier finish. Manhattans and Boulevardiers were written for that snap. Rittenhouse Bonded or Wild Turkey 101 Rye, or similar, is the snap. Bourbon softens them. US rye also ages in new charred oak, so it shares bourbon’s vanilla frame with a leaner grain center.
Scotch must be distilled and aged in Scotland — at least three years in oak. Blended Scotch (malt plus grain whisky) is the cocktail workhorse: highballs, Rob Roy, the body of a Penicillin. Famous Grouse covers that job. Monkey Shoulder is a blended malt — all malt from several distilleries, no grain whisky — also built for mixing. Heavily peated malt is seasoning. Laphroaig 10 or Ardbeg 10 belong as a float or rinse, not as a silent swap for bourbon.
Irish whiskey is often lighter and softer, especially everyday blends. Jameson is the soft highball and gentle sour. Single pot still — malted and unmalted barley, unique to Ireland — carries more body for stirred drinks. Reach for Redbreast, or similar, when the blend goes slack.
