How Long is Cold Brew Good for in the Fridge? Expert Answers.


Understanding Cold Brew

Cold brew is a type of coffee made by steeping coffee grounds in cold water for an extended period, typically overnight. The resulting drink is smooth, less acidic, and less bitter than traditional hot coffee. Unlike iced coffee, which is brewed with hot water and then chilled, cold brew is prepared without heat.

The absence of heat during the brewing process means that cold brew coffee can last much longer in the fridge compared to hot brewed coffee. While hot brewed coffee can start to go stale after just a few hours, cold brew coffee can stay fresh for up to two weeks in the fridge.

However, experts recommend consuming cold brew within seven days to ensure optimal taste and freshness.

So, if you want to enjoy cold brew at its finest, store it properly but try to consume it fresh for the perfect taste and aroma.

Factors That Affect Cold Brew Shelf Life

Cold brew coffee is a refreshing and delicious treat, but how long does it last in the fridge? There are several factors that affect its shelf life. The brew time plays a significant role. The longer the coffee is steeped, the stronger and more potent the flavor will be, but it may not last as long.

Water quality also plays a part. Hard water can cause the coffee to spoil more quickly. The roasting level of the coffee beans can also impact the shelf life. Darker roasts tend to last longer. Dilution of cold brew and the presence of additives, such as milk or sugar, can also affect its longevity.

Keep these factors in mind when storing your cold brew, and it will stay fresh for longer.

Signs Of Spoiled Cold Brew

Cold brew is a perfect treat at any time of the year, but it’s essential to know when it’s gone bad before drinking. Watch for visible signs of spoilage like mold, slime, or a cloudy texture. The scent can also alert you to spoilage.

Some hints of sour, rotten, or acidic aroma are indicators to discard the cold brew. Finally, taste the cold brew. Spoiled cold brew tastes different, and off compared to freshly brewed coffee. If you experience an aftertaste, avoid it. It is suggested that you consume cold brew within 24 hours of making it and refrigerate the rest for no more than a week.
