Coffee is one of the most popular beverages in the world. It is loved by many for its taste, aroma, and caffeine content. However, coffee lovers often face the dilemma of what to do with leftover coffee. Should they throw it out or can they drink it the next day? The question arises: is it ok to drink day old coffee?
There are varying opinions on this topic. Some people believe that drinking day old coffee is perfectly fine, while others argue that it can be harmful to health. The answer to this question depends on a few factors like the type of coffee, storage method, and personal preference.
Coffee is likely to lose its flavor and aroma when it sits out for an extended period. The oxidation process causes the coffee to taste stale and bitter. However, some people don’t mind the taste and still prefer to drink it. It’s worth noting that coffee with added milk or sugar may go bad faster than black coffee due to the dairy content.
Proper storage can also make a difference in the quality of day old coffee. Storing leftover coffee in an airtight container in the refrigerator can help prevent the growth of bacteria and mold. However, if the coffee has been sitting out at room temperature for over 24 hours, it’s best to discard it.
Understanding Coffee Spoilage
What Happens to Coffee After Brewing?
After brewing coffee, it starts to lose its freshness quickly as it comes into contact with oxygen. This process accelerates when the coffee is left sitting at room temperature. The coffee’s acidity level also gradually increases, leading to a sour taste.
How Long Does It Take for Coffee to Spoil?
Coffee can start spoiling as quickly as 30 minutes after brewing if left at room temperature. After two hours, bacteria will begin growing, and the chance of harmful pathogens appearing in the beverage increases significantly.
What Are the Signs of Spoiled Coffee?
Spoiled coffee will have an off smell and taste stale or sour. Mold can also start growing on old coffee grounds or liquid left unattended for too long.
Can Drinking Day-Old Coffee Make You Sick?
Drinking day-old coffee won’t necessarily make you sick immediately, but it can lead to unpleasant symptoms such as nausea, vomiting, and diarrhea in some cases. If consumed regularly over time, drinking spoiled coffee could result in more severe health issues.
How Can You Tell If Your Day-Old Coffee Is Safe to Drink?
When deciding whether day-old coffee is safe to drink or not, use your senses; smell and taste are usually reliable indicators of spoilage. If the beverage smells off or tastes different than usual, it’s best not to risk drinking it.
Alternatively, you can brew a fresh batch of coffee if you’re unsure about your older one’s safety.
Factors That Affect How Long Your Coffee Lasts
Several factors affect how long your brewed or unbrewed beans last before going bad:
When it comes to drinking day old coffee, it can be safe as long as it has been stored properly and doesn’t have a foul smell or taste. However, it is best to avoid drinking old brews altogether since they lack most of their original flavor profile. Proper storage techniques such as using an airtight container, keeping the coffee away from heat sources, and storing it in a cool place can help prolong its shelf life and prevent spoilage. Additionally, alternative options like brewing fresh coffee daily or trying cold brew or iced coffee can provide a better taste and caffeine content.
Temperature
Temperatures between 40°F (4°C) and 140°F (60°C) are considered “danger zones” for food safety because they allow bacteria growth. When storing brewed or unbrewed beans outside this range but still at room temperature, spoilage can occur in as little as two hours.
Humidity
Humidity also plays a role in coffee spoiling. Moisture allows mold to grow and affects the beans’ flavor profile, so avoid storing coffee near humidifiers or other sources of moisture.
Air Exposure
Air exposure is another factor that affects how long your coffee lasts. Oxygen degrades the beans’ quality and accelerates spoilage; thus, it’s best to store your beans in an airtight container.
How to Store Coffee Properly
To maximize your coffee’s shelf life, follow these tips:
Proper storage and personal preference are key factors when it comes to drinking day old coffee. While it may not necessarily make you sick, it can lead to unpleasant symptoms over time if consumed regularly. To prevent spoilage, store coffee in an airtight container, away from heat sources and direct sunlight, and brew fresh coffee daily. Alternatives to day old coffee include cold brew, iced coffee, using leftover brewed liquid for cooking or baking, and buying ready-to-drink options.
Store Your Coffee in an Airtight Container
As mentioned earlier, air exposure is one of the leading causes of coffee spoilage. To prevent this from happening, store your beans or brewed liquid in an airtight container away from heat sources like stovetops or ovens.

Stomach Discomfort
Drinking day-old coffee can lead to stomach discomfort such as nausea, vomiting, and diarrhea. These symptoms are caused by the high acidity levels in the coffee that increase over time, making the beverage more sour than usual.
Risk of Bacterial Infections
Leaving coffee sitting at room temperature for too long creates an environment conducive to bacterial growth. If consumed regularly over time, drinking spoiled coffee could result in more severe health issues like food poisoning or other bacterial infections.
Loss of Flavor and Aroma
Coffee’s flavor and aroma profile start deteriorating almost immediately after brewing. Within a few hours, most brewed liquid loses its full-bodied flavor due to oxidation. The longer it sits unattended, the duller its taste becomes.
Caffeine Content Decreases Over Time
The caffeine content in your day-old cup may be lower than your freshly brewed one since caffeine is sensitive to heat exposure and oxygenation. As soon as you brew your coffee, its caffeine levels start decreasing rapidly; thus a day-old cup will have significantly less caffeine than a fresh one.
Mold Growth on Old Grounds or Liquid
Mold growth is common in old grounds or liquid left unattended for too long. Mold thrives in damp environments like moist grounds or cups left open for days without cleaning them properly.
Inhaling mold spores found on these surfaces can cause respiratory problems like asthma attacks or allergic reactions that affect breathing quality negatively.
Is It Safe to Drink Day-Old Coffee?

Tips for Storing Coffee to Prevent Spoilage
Proper storage techniques can help extend the shelf life of coffee, whether it is brewed or unbrewed. Air, temperature, and humidity are factors that affect coffee spoilage, and it’s best to store coffee in an airtight container, away from heat sources, and in a cool place. Drinking day-old coffee is generally safe as long as it has been stored correctly, doesn’t have mold growth, and hasn’t lost its flavor profile. Alternatively, brewing fresh coffee daily is the best way to ensure maximum freshness and taste.
Use an Airtight Container
When storing coffee, it’s essential to use an airtight container that will keep out moisture and oxygen. Exposure to air causes oxidation, which can make your coffee stale and lead to spoilage. Choose a container with a tight-fitting lid made of glass or ceramic.
Keep Away from Heat Sources
Heat is another enemy of stored coffee. Avoid storing your beans or brewed liquid near heat sources like stovetops, ovens, or direct sunlight. Heat accelerates the aging process and can cause spoilage.
Store in a Cool Place
Storing your beans or brewed liquid in a cool place will help prolong their shelf life by slowing down the oxidation process. The ideal temperature range is between 60°F (15°C) and 70°F (21°C).
If you don’t have access to air conditioning, consider storing your brews in the refrigerator or freezer if you won’t be using them soon after purchase.
Grind Your Beans Right Before Brewing
Grinding your beans right before brewing preserves their freshness since ground beans oxidize faster than whole bean varieties. Consider investing in a quality grinder for home use so that you can grind fresh every time you brew.
Buy Fresh Beans Often
To ensure maximum freshness and flavor profile in every cup of coffee, buy fresh beans often rather than buying large quantities at once that may go stale before use.
If possible, buy whole bean varieties instead of pre-ground ones since they last longer when stored correctly.
How Long Can You Store Coffee?
The length of time coffee stays fresh depends on several factors such as:
- Type: Dark roasted coffees tend to stay fresher longer than light roasts.
- Origin: Some regions produce more robust flavors than others.
- Storage techniques: Proper storage techniques like those mentioned above will extend shelf life.
- Brewed or unbrewed: Brewed liquid spoils faster than unbrewed beans.
In general, you can store unopened whole bean varieties for up to six months in their original packaging. Once opened, transfer them to an airtight container and use within two weeks for maximum freshness.
When it comes to pre-ground coffee, it’s best only to buy what you can consume within one or two weeks since they lose their flavor profile much quicker than whole bean varieties.
Brewed coffee will start degrading almost immediately after brewing and should be consumed within the same day. If refrigerated, it may last up to three days but will have lost most of its flavor profile by then.
Proper storage can make a difference in the quality and safety of day old coffee, but it’s not recommended to drink it regularly. Oxygen exposure, light exposure, temperature, and humidity are all factors that affect coffee spoilage. The best alternative to day old coffee is to brew fresh coffee daily, or try cold brew, iced coffee, or using leftover brewed liquid for cooking and baking. Ready-to-drink options are also available.
Alternatives to Drinking Day Old Coffee
The best alternative to drinking day-old coffee is to brew fresh coffee daily. This ensures maximum freshness and flavor profile in every cup.
Make Cold Brew
Cold brew is a popular alternative to hot brewed coffee, and it’s easy to make at home without any special equipment. The process involves steeping coarsely ground beans in cold water for 12-24 hours, producing a smooth and less acidic beverage that can be enjoyed over ice.
Try Iced Coffee
Iced coffee is another popular alternative, especially during warmer months. It’s made by brewing regular hot coffee and pouring it over ice cubes or chilling brewed liquid in the refrigerator before serving.
Use Leftover Brewed Liquid for Cooking or Baking
If you have leftover brewed liquid that you don’t want to drink as-is, consider using it for cooking or baking instead of throwing it away. You can use brewed liquid as an ingredient in recipes like chocolate cake or chili con carne to add depth of flavor.
Buy Ready-To-Drink Options
If you’re short on time but still want your caffeine fix, consider buying ready-to-drink options like bottled cold brews or iced coffees available at most supermarkets and convenience stores.
