Whether you enjoy black coffee, a creamy latte, or a cup with milk, you may wonder: how long can coffee sit out? Leaving coffee out for too long can affect its taste, freshness, and safety. While black coffee lasts longer than coffee with milk or creamer, there are specific guidelines to follow. In this article, we’ll cover the safe time limits for coffee and how to store it properly.
How Long Can Black Coffee Sit Out?
Black coffee is more shelf-stable than coffee with milk or cream, but it still has its limits. Here’s what you need to know:
- At Room Temperature: Black coffee can sit out for up to 12 hours at room temperature. After 12 hours, it may develop a stale, bitter taste, although it’s unlikely to be unsafe to drink.
- In the Refrigerator: Black coffee can last up to 1 week in the refrigerator if stored in an airtight container.
- In the Freezer: For long-term storage, black coffee can be frozen for up to 2 months in a freezer-safe container.
Can You Drink Black Coffee Left Out Overnight?

How Long Can Coffee Sit Out With Milk, Cream, or Creamer?
Adding milk, cream, or creamer to coffee drastically reduces its shelf life. Dairy products encourage bacterial growth, so time is limited.
- At Room Temperature: Coffee with milk, cream, or creamer should sit out for no more than 2 hours. If the temperature is over 90°F (32°C), reduce this time to 1 hour.
- In the Refrigerator: Coffee with milk or cream can be stored in the refrigerator for up to 2 days in an airtight container.
- In the Freezer: Freezing coffee with milk is not recommended as dairy products can curdle after thawing.
Can You Drink Coffee With Milk Left Out Overnight?
No, it’s unsafe to drink coffee with milk that’s been left out overnight. The milk can spoil, leading to the growth of harmful bacteria that can cause foodborne illnesses.
How Long Can Iced Coffee Sit Out?
Iced coffee faces the same rules as hot coffee. It depends on whether milk or cream is present.
- Without Milk or Cream: Iced black coffee can sit out for up to 12 hours at room temperature, just like hot black coffee.
- With Milk or Cream: Iced coffee with milk or cream should only sit out for 2 hours at room temperature. After this, bacteria can begin to grow.
Can You Drink Iced Coffee Left Out Overnight?
If it’s black iced coffee with no milk or cream, it may still be drinkable, though it could taste stale. Iced coffee with milk should be thrown away if it’s been left out overnight.
How Long Can Brewed Coffee Sit Out?
Brewed coffee is more stable than coffee with milk but less stable than black coffee. Here’s how long brewed coffee can sit out:
- At Room Temperature: Brewed coffee can sit out for up to 12 hours, especially if it’s stored in an airtight pot.
- In a Coffee Pot or Carafe: If left in a carafe with a heating element, brewed coffee can stay warm for up to 4 hours, but its taste will degrade over time.
- In the Refrigerator: Brewed coffee can be stored in the fridge for 3–4 days in an airtight container.
How Long Can Coffee Sit in a Coffee Pot?
