Claim: Cold brew coffee has significantly more caffeine than regular coffee and can cause anxiety and heart palpitations

The claim that cold brew coffee has significantly more caffeine than regular coffee is mixed. Some sources, like Colipse Coffee and Drink Bare Brew, assert that cold brew can contain more caffeine due to its brewing method. However, other sources, including Healthline and Lifehacker, indicate that cold brew often has less caffeine than hot coffee, depending on the preparation. The assertion that cold brew can cause anxiety and heart palpitations is also debated, as individual reactions to caffeine vary widely, and not all studies support this claim. Thus, while there is some evidence for higher caffeine content, it is not universally accepted and varies by preparation method. All three graders point in the same direction, with minor differences. Gemini comes in highest (50%), while OpenAI is lowest (40%). Perplexity expresses higher confidence than Gemini on this claim. There is conflicting evidence regarding the caffeine content of cold brew coffee compared to regular coffee. While some sources claim that cold brew can have significantly more caffeine due to its brewing process, others argue that it typically contains less caffeine. This discrepancy arises from variations in brewing methods and serving sizes. Additionally, the potential for cold brew to cause anxiety and heart palpitations is not universally supported, as individual tolerance to caffeine can vary greatly. Therefore, the claim's validity is uncertain and depends on specific circumstances and individual responses to caffeine consumption.
