You’ll also have empowering knowledge for when you’re looking at new pieces of coffee equipment. Few coffee lovers are familiar enough with espresso to know how it’s really different.īy learning the main differences between espresso and drip coffee, you’ll know exactly what you’re drinking when you visit coffee shops. I used to manage a specialty coffee shop and people asked about this all the time. Since caffeine is easily extracted from coffee, your best bet for obtaining more caffeine is simply to use more ground coffee.If you’re not 100% sure how espresso is different than drip coffee, there’s no need to be ashamed. Essentially, you could take a whole bean and saturate it with water, eventually the caffeine will be removed, but how long do you imagine it will take?Įspresso is prepared using pressurized water, more ground coffee than used for drip, all of which result in a higher concentration of caffeine than drip. Under-extraction will happen with espresso when the grind is too coarse whereas you will have over-extraction if the grind is too fine.Īll these factors influence how quickly caffeine is extracted from coffee. Water reaches the surface area and saturates the grind with ease, as there is a greater contact area. With a finer grind you have the ability to extract caffeine faster. Grind can influence how quickly caffeine is extracted. The brewing time of an espresso shot is from 20-30 seconds. Roughly all of the available caffeine is released during the first minute of extraction. Temperature is going to make a big difference in how quickly caffeine is withdrawn from the bean. The ideal water temperature is near-boiling, 95-105☌. TemperatureĪbove we mentioned hot water acting as a solvent. The grinds need to be 100% saturated to extract all the caffeine available. Since all brewing methods don’t yield the same percentage of caffeine, let’s see what else can affect the buzz. Caffeine is extracted into the brew by hot water acting as a solvent. We know from earlier entries that caffeine is water soluble. 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.
