Less than you think

08/20/2010

This is my latest print in an attempt to shine light on some of the common misconceptions that surround espresso. However, this one is questionable. I’ve read many studies that suggest that a shot of espresso has less caffeine than an 8oz cup of drip/pour-over coffee and others that state the opposite, depending on how it’s measured. I tend to think a 1oz shot is going to have significantly less caffeine, does anyone out there know otherwise? Please let me know!

    According to my own research and years of experience drinking coffee, a 2 oz shot of espresso on average does contain less caffeine than 8 oz of coffee since espresso is usually made from darker roasts. Darker roasts have less caffeine. However, espresso has more caffeine per millilitre since it is made with less water.

      Thanks! Yeah, I think I’ve come to the conclusion that Coffee (the way it’s normally consumed) has much more caffeine. Glad you enjoy the blog!

    Let’s see if I can help shine some light.

    Drip coffee does have more caffeine than espresso because it takes longer to brew and espresso is usually a dark roast, like Vasco said, and only 20-30 seconds brewing. But, if you compare an 8oz. cup of coffee to 8oz. of espresso, from multiple shots, then the caffeine content is about the same.

    Here is a more detailed article to help explain it.

    Hey,

    I’m now following! I’m going to try and get some more coffee related posts on my blog too.

    I NEED to point out that darker roasts have THE SAME AMOUNT of caffeine if you measure by WEIGHT!

    It has slightly less if you measure by VOLUME, because once a bean goes into second crack (roasting) it expands further.

    Anyway, I look forward to following you!
    – Matt
