What about espresso? You always think espresso will “pick you up” quicker, but according to my one-time Starbucks working girlfriend, she claims that espresso has less caffeine than coffee.

I’d always imagined that espresso would be stronger - dictionary.com says espresso is “A strong coffee brewed by forcing steam under pressure through darkly roasted, powdered coffee beans.”

To me, ‘strong’ would imply that it is stronger than the average coffee. But thats just me - you all might each have a completely different take on it.

It wouldn’t surprise me if the Starbucks stuff is all out of whack, anyway.

on a per serving basis, a shot of espresso has about as much or less caffine than a normal sized cup. If you’re buying gigantiventi sized coffee, a tiny espresso cup has much less.

I wish this page spoke to caffeine levels in beer. I have an ongoing argument with a friend - I say no caffeine in beer, she disagrees.

Roland - That’s a damn fine question. Even though I’m immune to the effects of caffeine, I still drink Bawls because it’s so darn tasty.

Ahh, I found it on the Bawls site. 80mg per 12 oz serving.

This from a coffee roaster’s website: “Strong coffees (dark roasted) actually have less caffeine that a light roasted coffee. Darker roasts have less caffeine because they stay in the roaster longer and additional heat burns out more of the caffeine as well as the natural bean flavors. How about that shot of espresso? It too has less caffeine that a cup of brewed coffee. The reason is that water passes over the espresso grounds very quickly and one of the last things to be extracted is the caffeine. Hence less caffeine in espresso than a cup of brew coffee.”

…and there’s no caffeine in canadian mountain dew. it’s against the law!

Caffeine in beer? Wouldn’t they counteract each other?

MorganJan 29, 2004 at 6:53PM

I’m pretty certain that some coffee based beers have some level of caffeine. Caffeine in beer isn’t all that common, though.

From what I learned while working at a local coffee shop, a standard 1oz espresso pulled for ~20 seconds has 80% the caffeine of one cup of coffee.

More in juice than Mountain Dew? Anyone else surprised?

Depends upon the coffee bean, how it’s roasted, etc.

A latte is made my adding milk to an espresso, a cappuccino by adding foamed milk to espresso, an americano by adding hot water to an espresso. So, they all have the same caffiene content.

Not sure about filter, caffetierre, etc. I know filter has less cholestorol as it’s absorbed by the paper.

Vodka Red Bull cocktails - alcohol and caffiene.

This URL at about.com suggests that a DOUBLE espresso has less caffeine than a cup of coffee. A double espresso is what you would have in a medium (or grande) Starbucks drink, like a latte. However, an Americano (and maybe a few other drinks) have an extra shot, so a small (tall) would have two shots.
