Crème de café is a sweet, low-proof coffee liqueur made by steeping roasted coffee in a neutral spirit and sweetening it heavily.
Coffee liqueurs
Kahlúa, Tia Maria, and others can take its place at the same amount. Strength and sugar vary, so taste as you go.
Cold espresso
Mix it with a barspoon of syrup. You get the coffee but no strength.
Irish cream
This is no swap. Baileys brings dairy, not coffee.
Nothing in it spoils, but the coffee aroma fades once the bottle is open. After a year it tastes sweeter and less of coffee than it did. Keep it closed and dark, and buy the smaller bottle if the bar goes through it slowly.
