Since there is a finite amount of caffeine to extract in coffee, what can cause this difference in caffeine concentration? Moreover what does it take to extract caffeine from coffee? What causes the difference in caffeine levels with Espresso and Drip? So there is some truth in the assumption when considering concentration and time of ingestion. Caffeine can be more rapidly assimilated when taken in concentrated dosages hitting your central nervous system differently than if you sipped a drip cup over the course of an hour. Maybe I’m a special case though, which my family would agree.Īlong the same lines, espresso may have less caffeine, but how quickly do you consume a shot versus an entire mug of brewed coffee? You generally drink espresso much faster. However, if I’m feeling edgy caffeine only leads to more anxiety. If I’m already in a good mood caffeine generally ups the ante. My current mood can alter my reactions to caffeine. I even find different effects dependent on the day. The difference in the serving size is where the discrepancy lies less caffeine in espresso from a beverage perspective.īy now we know caffeine affects us all in our own way. By concentration we see espresso having more caffeine. Let’s examine caffeine concentration per ounce.Ī single shot of espresso has an estimated 40 mg per ounce whereas a brewed cup only has around 10 mg in each ounce. But, that doesn’t seem like a fair comparison given the difference in volume. So actually there is more caffeine in an average cup of drip coffee than in espresso. Whereas a 12 oz brewed coffee has about 120 milligrams. One 2 oz double espresso shot has about 80 milligrams of caffeine. However, when you get down to numbers the amount of caffeine is greater in a drip cup of coffee. I mean isn’t that why you only ever find hardcore coffee aficionados ordering straight up shots of espresso. Can different brewing methods impact our caffeine consumption?Ĭommon assumption seems to be that a shot of espresso has more caffeine than an average drip cup of coffee.
