Espresso vs. Moka

[TheRealBonger]

I read on another board that espresso has on average 70mg of caffiene and a regular cup of joe can have 320mg per cup. I was wondering what the content of caffeine in Moka comes out to be.

On a side note, had a personal record for false crema in my moka pot. Quite possibly the tastiest Moka I have ever produced. Made with my first batch of home roast on top of it all. I love these boards.

Quantitative: no idea

Qualitative: I drank three (2-cuppers) of (really good!) moka back-to-back one day and thought my heart was going to explode. Felt like crawling out of my skin. Caffeine overdose for sure. Terrible feeling. Never drank enough drip, press or espresso to get that feeling. Beware the mokapot is all I know.

Haha, good to know. I think I will limit my Moka intake to one 3-cup pot in one sitting. I have had to much caffeine before and it is not a good feeling.

I think that Germantownrob, for one, can drink three of these without being phased. YMMV.

There's a lot more ground coffee used to achieve a full cup of in a moka pot vs. drip/french press. Espresso serving size is quite small. If you filled a whole coffee mug up with Espresso, better enter 911 on redial...

I've had 8 shots of espresso before (which did fill up a coffee cup), caught a pretty nice buzz, got a little jittery but it wasn't anything dramatic. That was I guess about 560mg of caffeine.

I drink 2 six cuppers every morning and a couple of 4 cuppers (thanks to Mr Moo) during the day . I can drink espresso non stop but I do believe the moka is stronger than a drip of press per 6-8oz cup.

I have searched the obvious net places but a scientific confirmation on mg/caffeine per moka ounce does not seem to exist. Odd, really, given the Italians must drink about a billion cups/day of the stuff.

Claims that a typical 2-oz double shot of espresso delivers 65-100mg are all over the place but noboby sez from whence the data was derived. Found around, stuff like this from coffeeFAQ:

Drip 115-175 (7 oz cup)
Espresso 100 1 serving (1-2oz)
Brewed 80-135 (7 oz cup)

This looks like imaginary drivel to me; no resources cited. Espresso as
100 mg for 1-2 ounces? WTF? 1-2 ounces is quite the variance. I think people see something somewhere and then copy and paste it somewhere else.

[TheRealBonger]

You are probably correct in that assumption Mister Moo. I found that in one of the other coffee forums, with nothing cited, and I had not thought about all the variables possible in testing something of this nature. It doesn't really matter to me, because I am going to drink what I like, in whatever quantity I like. Just a curious mind asking questions. Once I feel like I have had too much, time to drink more water, and continue on.

Objective:
To analyse the distribution of caffeine doses obtainable from espresso coffee sold by a sample of commercial coffee vendors located on the Gold Coast, Qld, Australia.

Design:
A cross section of ‘‘Espresso/short black’’ coffee samples were purchased and analysed for their caffeine content using micel-lar electrokinetic capillary chromatography (MEKC).
Coffees were collected using systematic cluster sampling across five major retail centres.

Results:
Ninety-seven espresso samples were analysed.
The mean (±SD) quantity of caffeine was 106 ± 38 mg/serve with a concentration of 2473 ± 1092 mg/l.
There was considerable variation in caffeine content.
The range per serve was 25–214 mg whilst the concentration range was 580–7000 mg/l.
Twenty-four samples (24.7%) contained 120 mg of caffeine or higher and 12 samples (12.3%) exceeded 167 mg per serve.

Conclusions and implications:
The number of heavily caffeinated samples differentiates these findings from frequently cited caffeine values and supports similar data recently collected throughout the United Kingdom. As a result, the accuracy of any previous intakemodelling regarding caffeine use in the Australian population is in doubt. The present data suggests that the probability of consumerexposure to high caffeine doses is greater than previously anticipated. Greater sample numbers from a broader selection of venues isrequired to confirm the extent of caffeine content variance within retail ground coffees.

================================================== =======

The amount of caffeine in a cup of coffee can vary greatly, depending on its origin or the composition of the blend, the method of brewing and the strength of the brew. Instant, or soluble, coffee generally contains less caffeine than roast and ground coffee, but may be consumed in greater volume. Robusta coffees have about twice as much caffeine as arabicas. A 'cup' is usually understood to contain 150 ml (5 oz in the United States) but an espresso may be as small as 40 ml.

Bean type, varietal, geographical source of bean, roast, and brewing method all seem to make the whole thing pretty variable. You could always test for yourself with this kit.

Drink more coffee now, plenty of time to sleep after you are dead.

The last part is right. As I suspected, people are just guessing at all the rest.

Know your own limits for caffeine toxicity.

I don't need a scientific study, if a can of coke is 34-mg of caffeine and I can drink 4 cans and hardly feel a buzz then I would say a 6 cup moka pot contains more caffeine than 136 mg no matter what origin or roast style went into it. I can also safely say I have had 6 oz cups of coffee from diners, friends, and such that where very weak and I could drink as many cups as put in front of me. Starbucks and other cafes I have been to make a much stronger in caffeine cup and 16oz seems to be my limit with out getting over caffeinated.

So numbers don't mean much to me the actual results do.
