How long does the cold brew last in the refrigerator? Experts reveal


If, like many people across the country, you like cold brew, you’re probably wondering how to make your favorite java last a little longer in the fridge. Whether you do it yourself or buy it in the store, have you ever wondered if you are storing your cold brew properly? Also, do you know how long can you keep cold brewed coffee in the refrigerator? Here, coffee experts explain how to ensure your cold brew stays fresher longer, stays food safe, and tastes great.

What is cold brew?

First, let’s differentiate cold brew from your standard brewed coffee. According to Travis Beckett, Seattle regional educator for Counter Culture Coffee, “regular coffee” (ie filter filter, espresso, or pour) is typically made with hot water between 90 and 96 degrees Celsius. This can be poured over ice for those who prefer iced coffee drinks. Whether served hot or cold, this type of coffee is “aromatic” and “bright,” Beckett notes.

Cold brew, as the name suggests, uses cooler water (usually a refrigerator temperature of around 3 degrees Celsius or a room temperature of around 21 degrees Celsius) during the brewing process, explains Beckett. Since the water is colder, the brewing takes longer. For example, brewing a cold brew in the fridge might take 18 hours, but an over-the-counter brew might only take 12 hours (hot coffee, on the other hand, only takes a few minutes to brew). So what’s the benefit of waiting that long for a cup of coffee? Beckett says the combination of a longer brew time and cooler water creates a coffee that has a fuller body, smoother texture, and delicate aromas.

Cold infusion versus cold infusion concentrate

In addition to the standard ready-to-drink cold brew, you can also make cold brew concentrate. While “ready-to-drink cold brew uses the right amount of coffee right from the start to give you the strength and flavor you want” (so no dilution is needed), the concentrate is made by “using more coffee grounds. coffee or less water, and needs to dilute with cold water after filtering the soil, “says Beckett. If you order a cold brew in a cafe, they often use a concentrate, which saves money. space and is more efficient when serving a crowd. Beckett says that for the home coffeemaker there is usually no need to make a concentrate. He recommends “coffee lovers make their cold brew at home using a ready-to-drink strength recipe. ”He personally prepares his cold infusion in the refrigerator for 18 hours, then pours it over ice.

Keeping the infusion cold

If you are making a cold bulk brew, you need to make sure you store it properly. Beckett recommends keeping your cold brew (and / or concentrate) in a closed-top (sealed glass or plastic) container in the refrigerator (storage at room temperature is more prone to bacterial growth). You will want to drink your cold brew in a few days; longer, and you risk the brew oxidizing, causing it to taste stale. According to Chi Sum, co-founder of Coffee Project NY, “since each person’s recipe and choice of beans (level of roast, size of grind, etc.) are different, it contributes to the shelf life of the coffee before it is brewed. to taste stale, flat, and [undergoes] a possible change in acidity. She saw anywhere between two days and seven days.

Selina Viguera, chef at Blue Bottle Coffee Abbot Kinney, says they keep their brew concentrates cold for up to two weeks, but once they’ve been diluted they try to serve them within three or four days. . “Fresher is always better when it comes to drinking your cold brew, and doing smaller batches more frequently will work better than a large batch that just sit and sit,” Beckett advises.

If you are really dedicated to the cause of cold brew and want to extend the duration of your cold brew, the only way to do that is to remove the air from the storage container (similar to a bottle of wine), Beckett notes. While impractical for the most part, there are home devices available if you want to experiment. This is what coffee shops often do, putting their cold brew in a keg and “rinsing it with carbon dioxide to make it fresher for longer,” Beckett notes. You can mimic the process at home if you have a small kegerator.

If optimal longevity is your goal, Viguera recommends storing your cold brew in the refrigerator as a concentrate; you can then dilute it with water or milk if needed (diluting it earlier can impact its shelf life). Finally, in accordance with best food safety practices, Beckett recommends washing your brewer well between batches.
