Cold Brew Coffee: Everything You Need to Know

For coffee enthusiasts, cold brew coffee is no longer just a trend. Cold brew coffee has become a staple in coffee shops and homes worldwide.

Not only is it a refreshing change of pace from the usual hot coffee, but it also has a smooth taste and can be enjoyed at any time of the day. However, the big question always comes up – how long does cold brew last?

Cold Brew Shelf Life Breakdown

The shelf life of cold brew coffee can vary depending on how it is stored. When stored in the fridge, the ideal temperature for cold brew is between 34-40F.

At this temperature, cold brew coffee can last up to 2 weeks. It’s important to pour your cold brew into an airtight container right after it has finished steeping to prevent it from going stale or developing off-flavors.

When left out of the fridge, the shelf life of cold brew is much shorter. In warmer temperatures between 68-72F degrees, cold brew can only last a few hours.

Any longer, and the risk of bacterial growth increases, making it unsafe to consume. If you plan to take your cold brew on-the-go, it is best to use an insulated bottle or thermos to keep it cool and fresh.

Cold Brew Concentrate Shelf Life

When it comes to cold brew concentrate, the shelf life is slightly longer than regular cold brew. Concentrate is made by steeping coffee grounds in cold water for a longer period, resulting in a more potent and flavorful brew.

Because of its higher coffee-to-water ratio, it can last up to 2-3 weeks in the fridge when stored properly. However, keep in mind that the stronger coffee concentration can still go bad after a while, so its important to pay attention to any unusual taste or odor.

Starbucks Cold Brew

If you’re a fan of Starbucks, you’re in luck.

Starbucks Cold Brew is specifically designed to last longer than regular cold brew coffee.

Starbucks uses a blend of 100% Arabica beans that are steeped in cold water for 20 hours, resulting in a smoother and less bitter taste. According to Starbucks, their cold brew can last up to 7 days when stored in the fridge and properly sealed.

Why Cold Brew Lasts Longer

The reason why cold brew coffee lasts longer than regular hot-brewed coffee is that the cold water extraction process extracts less acid and oils found in coffee beans. By steeping the grounds in cold water, the chemical reactions that occur when hot water hits the beans are avoided.

The result is a smoother, less acidic coffee that’s easier on the digestion.

Extending Cold Brew Shelf Life

There are a few things you can do to extend the shelf life of your cold brew coffee. First, invest in an airtight container that fits your brewing needs.

Glass bottles or containers with airtight lids work best as they prevent any air or moisture from getting into the coffee. Second, maintain a consistent temperature between 34-40F when storing your cold brew.

Lastly, take care not to dilute your cold brew too much with water or ice cubes.

Cold Brew vs Iced Coffee

Many people confuse cold brew coffee and iced coffee. While both are served over ice, their brewing methods and taste profiles differ.

Iced coffee is the result of hot coffee brewed and served over ice, whereas cold brew is brewed with cold water over an extended period. The result is a smoother, less acidic taste with a more robust coffee flavor.

Iced coffee, on the other hand, can have a more acidic flavor because it is brewed with hot water.


In conclusion, cold brew coffee has become a popular choice for coffee lovers due to its mild flavor, low acidity, and extended shelf life. To ensure that your cold brew is as fresh as possible, consider using airtight containers, storing it in the fridge, and avoid diluting it with too much water or ice.

Understanding the differences between cold brew and iced coffee can also help you make the perfect coffee choice for your preferences. Additionally, factors such as the addition of milk, cream, or sugar can affect the shelf life of cold brew, and it is important to pay attention to the steeping time and the lifespan of nitro cold brew.

With these tips and knowledge, you can enjoy the perfect cup of cold brew coffee anytime, anywhere.
