Can Cold Brew Coffee Make You Sick? Find Out What Experts Say
Cold brew coffee has become a favorite for many coffee lovers. Its smooth, mellow flavor and lower acidity make it a refreshing choice. But sometimes, people worry: can cold brew coffee make you sick? In this guide, we’ll explore what experts say about the safety of cold brew coffee, how to prepare it safely, and what to watch out for to avoid any health issues.
Understanding Cold Brew Coffee
Cold brew coffee is made by steeping coarsely ground coffee beans in cold or room temperature water for an extended period, typically 12 to 24 hours. This slow extraction method produces a coffee concentrate that is less acidic and bitter compared to hot brewed coffee.

Because the brewing process uses cold water, some worry about bacteria growing during the long steeping time. Let’s dive deeper into this concern.
Step 1: Know the Risks of Cold Brew Coffee
Bacterial Growth During Brewing
Unlike hot coffee, which is brewed at high temperatures that kill most bacteria, cold brew is made at room temperature or cold conditions. This creates an environment where bacteria can potentially grow if the coffee is left out too long or not stored properly.
Potential Contamination Sources
- Unclean equipment
- Using water that is not clean or filtered
- Improper refrigeration after brewing
- Using old or stale coffee beans
Experts say that if these guidelines are followed, the risk of contamination is minimal.
Step 2: How to Make Cold Brew Coffee Safely
Gather Fresh Ingredients and Clean Equipment
- Use fresh, high-quality coffee beans.
- Use filtered or bottled water to avoid contaminants.
- Ensure your cold brew maker, jars, and utensils are thoroughly cleaned.
Use Proper Brewing Time and Temperature
- Steep coffee for 12 to 24 hours in the fridge or at room temperature (preferably under 70°F/21°C).
- Longer steeping at room temperature increases bacterial risk — refrigeration is safer.
Store Cold Brew Properly
- Transfer brewed coffee into airtight containers.
- Refrigerate immediately after brewing.
- Consume within 5 to 7 days for best safety and flavor.
Step 3: Recognize Signs That Cold Brew Coffee May Be Spoiled
- Unusual smell: Sour or off odors indicate spoilage.
- Cloudy or strange appearance: A change in clarity or color can signal bacteria.
- Off taste: Bitter, sour, or metallic flavors suggest the brew has gone bad.
If you notice any of these signs, it’s best to discard the cold brew immediately.
Step 4: Who Should Be Cautious with Cold Brew Coffee?
While most healthy adults tolerate cold brew coffee well, some groups should be cautious:
- People with weakened immune systems: They are more susceptible to foodborne illnesses.
- Individuals sensitive to caffeine: Cold brew can be stronger in caffeine concentration.
- Those with stomach issues: Though less acidic, cold brew can still irritate some stomachs.
Consult your healthcare provider if you have concerns about consuming cold brew.
Practical Tips for Enjoying Cold Brew Safely
- Make small batches to avoid keeping cold brew too long.
- Label containers with the brewing date.
- Use cold brew coffee makers designed for easy cleaning and airtight storage.
- Always taste a small amount before drinking to check freshness.

Conclusion: Can Cold Brew Coffee Make You Sick?
