Your cold brew could be contaminated with bacteria! How to avoid?

Cold brew, also known as cold brew coffee, is a method of extracting coffee with water at low temperatures (which can be equal to or lower than room temperature) for a certain period (usually 24 hours). Experts say that low temperatures are the ideal environment for some bacteria to grow. Meanwhile, cold brew processing methods take place at low temperatures for a long time. Therefore, bacteria such as salmonella and E.coli can multiply vigorously and produce substances that affect health.

Additionally, because a cup of cold brew coffee has a lower acidity and is not exposed to high brewing temperatures, if it is not stored in the appropriate environment, away from direct light, the coffee can become spoiled. spoils, loses its brightness, and has a moldy, unpleasant aroma and taste.

Cold brew coffee researchers warn that there are currently very few publicized cases of consumers becoming sick from drinking poorly prepared cold coffee. But if prepared incorrectly, the substances produced in cold brew will still be harmful to the body if used for a long time. Therefore, in stores, bartenders need to understand and take as many precautions as possible.

Using incorrect brewing temperature and exposing coffee to air is the main cause of a cup of coffee containing many toxic substances. Therefore, when preparing cold brew, we should use fresh cold water to brew and not use ice to better adjust the brewing temperature. Additionally, any cold incubation lasting more than two hours should be stored in the refrigerator with a recommended incubation temperature of -1°C to 5.5°C (30.2°F to 41.9°F).

Besides, to avoid mold or bacteria growth, it should be consumed within three weeks of preparation. If you don’t use it in time, you can freeze the coffee (leave about 5% of the jar space empty so the liquid expands) to extend its shelf life.

A cup of cold brew coffee is truly attractive with its delicate aromas, and a wonderful feeling of relaxation and awakening. But it can also have harmful health effects if prepared incorrectly and using poor quality ingredients. Therefore, if you want to enjoy it, choose reputable coffee shops or learn carefully how to make it and use quality ingredients if brewing at home.
