How Long Does Coffee Last in the Fridge?
You brewed a big pot of coffee in the morning, but life got busy. Now it’s late afternoon, and you’re wondering if that leftover coffee in the fridge is still okay to drink. How long does coffee last in the fridge before it goes bad?
Whether you’re storing cold brew, black coffee, or a leftover latte, understanding how long coffee stays fresh in the fridge can save your taste buds—and your stomach.
How Long Does Brewed Coffee Last in the Fridge?
Quick Answer:
-
Black coffee (unsweetened, no milk): up to 4–7 days
-
Cold brew concentrate: up to 10–14 days
-
Coffee with milk/cream: 1–2 days
-
Iced lattes or sweetened drinks: best within 24 hours
These are general guidelines assuming your coffee is stored in an airtight container and placed in the coldest part of the fridge.
What Affects Coffee’s Shelf Life?
Several factors influence how long coffee stays good:
-
Ingredients (e.g., milk shortens shelf life)
-
Storage method (airtight vs open cup)
-
Temperature (lower fridge temps preserve better)
-
Roast freshness (older grounds spoil faster)
Oxygen and moisture are the biggest enemies. Exposure leads to stale flavors and, over time, microbial growth.
Signs Your Stored Coffee Has Gone Bad
Coffee doesn’t spoil like meat or dairy, but it does go “off.” Watch for:
-
Sour or rancid smell
-
Mold or floating film on surface
-
Cloudiness or separation
-
Bitter, harsh taste
If your refrigerated coffee smells odd or tastes “off,” play it safe—don’t drink it.
Can You Refrigerate Coffee in the Coffee Pot?
It’s not ideal.
Most coffee pots aren’t sealed containers, and the open air inside your fridge can quickly degrade the flavor. Instead:
-
Transfer leftover coffee to a glass jar with a tight lid or a thermos.
-
Avoid plastic containers if possible—they can absorb and retain old odors.
Cold Brew vs Regular Coffee Storage
| Type of Coffee | Fridge Life | Notes |
|---|---|---|
| Black Coffee | 4–7 days | Best flavor within 3 days |
| Cold Brew | 10–14 days | Concentrate lasts longer |
| Cold Brew (diluted) | 2–3 days | Drink sooner after diluting |
| With Milk/Cream | 1–2 days | Higher spoilage risk |
| Iced Espresso Drinks | 24 hours max | Flavor and safety degrade quickly |
Cold brew lasts longer because it’s brewed slowly and stored cold from the start. Diluted or sweetened versions don’t last as long.
Does Coffee Taste Worse After Refrigeration?
It can. Reheated or cold-stored coffee:
-
Loses aromatics and complex notes
-
Tastes bitter or flat
-
May develop a metallic or sour flavor
To minimize flavor loss:
-
Store it as soon as possible after brewing
-
Avoid sweeteners or milk if you plan to store
-
Use high-quality, fresh beans
Can You Reheat Refrigerated Coffee?
Yes—but do it gently:
-
Use the stovetop on low heat or microwave in short intervals
-
Avoid boiling—it causes bitterness and degrades flavor
-
Stir before sipping to redistribute oils and solids
Pro tip: Consider drinking stored coffee as iced coffee instead of reheating.
How to Store Coffee in the Fridge (Properly)
1. Let it cool first
Hot coffee going into the fridge causes condensation and can raise the fridge temp.
2. Use an airtight container
Mason jars, screw-top bottles, or stainless steel thermoses are ideal.
3. Label the date
If you store often, mark the date to track freshness.
4. Avoid added dairy or sugar
Only add creamers or flavorings when you’re ready to drink.
Can You Freeze Brewed Coffee?
Yes. Brewed coffee can be frozen into:
-
Ice cubes (great for iced coffee)
-
Frozen portions (thawed for recipes or reheating)
Freezing locks in the current flavor, but some nuance is lost over time. Drink within 1 month for best results.
How Long Does Coffee With Cream Last in the Fridge?
Only 1 to 2 days, even when sealed.
Milk and cream spoil quickly, especially when mixed with coffee, which is slightly acidic. After 48 hours, you’re risking both bad taste and food safety issues.
If you like adding cream, consider storing the black coffee separately and adding cream only when ready to drink.
What About Coffee Grounds or Beans?
Just to clarify:
-
Ground coffee lasts 1–2 weeks once opened
-
Whole beans can stay fresh for up to a month in the pantry
-
Storing beans in the fridge is not recommended due to condensation and odor absorption
Keep beans in a cool, dark, airtight container—not the fridge.

Final Thoughts
Coffee doesn’t last forever—but with a few smart moves, it can hold up well for several days in the fridge. Cold brew and plain black coffee are your best bets for storage. Once you add milk or sugar, treat it like any other perishable food: drink it soon or toss it out.
What’s your favorite way to reuse leftover coffee—iced, reheated, or frozen into cubes?
