Nightcap (drink)

For example, a small alcoholic beverage or glass of warm milk can supposedly promote a good night's sleep.

They should not be served chilled or on the rocks, because a nightcap is supposed to induce a feeling of warmth.

[8] Other traditional nightcaps include brown liquor like brandy or bourbon,[7] and cream-based liqueurs such as Irish cream.

[10] Since some nightcaps are made of amaro, a digestif, they are believed to also make settling into bed easier by promoting digestion.

[8] A nightcap was originally alcoholic, since it warms drinkers and helps them sleep, just like the garment of the same name.
