In this post, you will find out how long can coffee actually sit out and what happens if you drink day-old or even older brewed coffee. Brewed coffee can only last for 30 minutes at room temperature without its flavor being notably compromised. After a couple of more hours, apart from losing its aromatic compounds, the coffee would develop off-flavors and an unpleasant bitter taste. Nevertheless, plain black coffee can sit out at room temperature for more than 24 hours after brewing.
It will still be considered safe to consume, though its original flavor will be lost. This applies to almond milk coffee too. Anyway, no matter whether you keep your coffee at room temperature or in the fridge, the level of flavor preservation depends on the storage container you use. If you leave your coffee to sit out for too long, it will inevitably start to go bad. According to those who are rigorous about the flavor profile of their caffeinated drink, the coffee is good for only 30 minutes post brewing.
At the same time, others would make a full pot of drip coffee on Sunday and have it daily throughout the following week without even storing it in the fridge. But what actually happens to your coffee if you decide to let it sit out for that long?
Coffee goes stale because of a chemical reaction called oxidation. This reaction is actually quite common and involves electrons being transferred from one molecule to another. This process occurs much more rapidly at higher temperatures. This is why cold brew coffee preserves its flavor for longer than hot brew. By the time your freshly brewed coffee cools off — which usually takes around 30 minutes — it has actually lost most of its pleasant flavor and aroma.
With that being said, letting your coffee sit in an airtight container would limit the oxidative reaction and keep the flavors in your brew for longer. If you keep your brew in the fridge at a lower temperature, this would also decrease the rate at which your coffee loses its aroma. Just make sure you keep the drink in a tightly sealed container, as coffee is very prone to picking up the flavors of other food items that you store in the fridge. No matter where you leave your coffee or what storage container you use, you should still keep in mind that once brewed, its pleasant flavor will inevitably deteriorate with time.
Unfortunately, there is a lack of scientific research and food safety guidance on proper coffee storage. More research on coffee storage and safety is needed. When stored properly, whole coffee beans and even ground coffee can last for a long time. Where you store coffee — whether on the counter or in the pantry, fridge, or freezer — also makes a difference. Cold temperatures in the fridge or freezer can affect the taste of dry coffee, but they can also preserve coffee for longer periods.
Properly stored, dry coffee can generally last for a very long time. Depending on the manufacturer, packaging, and when you purchased the coffee, this could be a few weeks to months or more. Once a package of roasted coffee beans is opened, the beans will stay fresh for 1—3 weeks. For best results, transfer opened coffee beans to a dry, airtight container that blocks out light.
Keep the container at room temperature away from any heat sources. You can also keep coffee beans in the freezer in sealed containers for 3—4 months. Be sure there is no water present in the container before freezing. Coffee beans that have been kept past these time periods may taste stale or lose freshness. Degassing valves, which look like small circular vents, allow packaged coffee to release carbon dioxide that develops during roasting. This can improve freshness and prolong shelf life 3.
Unopened roasted coffee beans will stay fresh until their best-by date. Opened beans stored in an airtight container at room temperature away from heat and light will stay fresh for 1—3 weeks. Opened packages of freshly ground coffee should be kept in an opaque, airtight container at room temperature. Keep ground coffee away from heat, light, and moisture. Ground coffee stored in this way will typically stay fresh for 1—2 weeks.
It will stay fresh for up to 2 weeks in the fridge and 1 month in the freezer. Instant coffee is a type of ground coffee that has a longer shelf life.
Some say that instant coffee can last for 2—20 years when stored properly — meaning in a sealed package or airtight container in a cool, dry, dark place. Opened packages of instant coffee are also thought to last for up to several years. Check the packaging to see what the manufacturer recommends.
