    Things that make you go hhhmmm...

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    10 years old but hhhhmmmmm.....

    Addicted to Java? Dont press it!

    Many coffee aficionados eschew the filtered brew, arguing that filters remove some of a bean’s savory flavor. What filtering really does -- besides screening out gritty grounds -- is eliminate coffee’s oils, rich in alcohols known as diterpenes. Two of these alcohols, cafestol and kahweol, can elicit a number of unhealthy changes in the blood of regular coffee drinkers.

    I thought that pouring boiling water into coffee grinds will burn the coffee, and the taste will be awful.... :o

    Could it be that they are drinking what is essentially "burnt" coffee?

    I agree... "almost a liter of the coffee daily for 24 weeks" is way OTT!!! I dont think any experiment would find that much coffee drank for that period of time is healthy, which ever way you make it.

    Well if you look at caffeine content of drinks. I proper coffee not instant crap is equal to 6 cans of a cola drink. A cola drink contains 36-46 mg. They say the healthy limit for an adult is 400-450mg of caffeine a day. So two cups would put you over the caffeine limit!

    so put me in the un-healthy basket...

    Yeh, I guess it all depends on how quick and frequent you drink.
    A normal espresso should have around 200mg of caffeine, so, if you hit yourself 5shots continuously,
    thats about 1g, which will bring you to possible toxicity. 10g caffiene is associated with death.

    how many coffees a day should we all be drinking i have been told by my doctor that for every coffee you have, drink 1 glass of water what do you all think????
    Ill say Ill try to stick on that rule, definitely you dont want to buildup the caffeine(purines) in you body!
    Especially men, more chance to develope gout....

    Sorry, too much bullshits here....

    Geez... is there a caffeine anonymous? ;)

    Im over the limit by about 9:00 a.m. And I generally will have quite a few more during the day... probably 3-4 times the limit (on a good day!!!)

    Mate, a shot of espresso only has on average 40mg of caffeine.

    Youre talking about drip coffee, which has about 60-180mg.


    I had an octo-shot last week, and I didnt die or even feel ill. I had roughly the equivalent of 2 cups of drip coffee, caffeine-wise.

    An octo-shot nunu? No wonder your bunny has a pancake on its head :)

    I agree with the idea of drinking a glass of water after every coffee - only to clear the palate for the next shot!

    Seriously though, there is quite a bit of evidence to support the health benefits of drinking coffee - mrnaive...no offense, but I think youre a bit niaive when it comes to those stats re caffiene. After all, when was the last time you heard of someone dying from a coffee od?

    nunu 40mg is the lowest content youd find that would have to be using a very dark roasted (darker roast less caffeine) arabica beans and only be a single shot. On the other hand if you have doubles like me and were using robusta then it would be over the 100mg mark for sure. There is a big range of values in accordance with the beans/roast etc, so i guess everyone is kinda right ;) Im not sure how much is considered an OD but the healthy limit is 400-450mg a day...

    Mate, I reckon your figures are inaccurate. "200mg of caffeine for a normal espreso"... I seriously doubt that. What is your source for this info?

    Do the math. The only possible way you can have 200mg of caffeine in a single shot of espresso is if you are using 100% Robusto beans. And not just any Robusto beans. Youd have to be using the beans with the highest caffeine content known in order to even have a chance of getting that much caffeine into the cup!!

    The LD50 for caffeine is 150-200mg per kilogram of mass for humans. Roughly 10g for the average adult.

    Re: Things that make you go hhhmmm...

    em, sounds like a little bit of debate here, let me clarify myself ;)

    The source of 200mg is the max possible dose I took, its always worth the take the value higher than lower (safety reason).

    mrnaive...no offense, but I think youre a bit niaive when it comes to those stats re caffiene. *After all, when was the last time you heard of someone dying from a coffee od?
    No problem dennis, just a bit of data availble for sharing...

    *****The reported lethal oral dose is 10 g (150–200 mg/kg), Coffee contains 50–200 mg (tea, 40–100 mg) of caffeine per cup depending on how it is brewed.*****(Poisoning & Drug Overdose, Fifth Edition, Kent R. Olson)

    Hope that will help clarify a bit.

    Yep - in other words, if I drink more than 80 cups of coffee in the one day...Im a dead man! ;D

    Re: Things that make you go hhhmmm...

    If you dig for the source of the 120mg of caffeine per shot of espresso youll find that its either a double shot or made from robusta. Every source that I have been able to track down for the 100-120mg of caffeine in a shot of espresso made no differentiation between arabica and robusta beans and was using 2 ozs as a serving size.

    On the other hand every source that differentiated between arabica and robusta gives the caffeine content of 1 oz of espresso made from arabica beans as 35-50mg with most stating 40mg.

    Unattributed figures with no volumes attached such as the espresso one given in your table are virtually worthless as there is no context to judge them in.

    Re: Things that make you go hhhmmm...

    I thought espresso had less caffeine in it than instant, french press, dripolator etc due to the technique of extraction.

    Basically because espresso coffee is extracted fast and under pressure, more of the flavour oils are extracted and less caffeine is extracted. However, with the other methods, the coffee is soaking in the hot water over a longer period of time, allowing more caffeine to leach out of the grounds into the water.

    I know that if I drink any other of these coffees I get the shakes after one cup - especially instant.

    You are quite correct Lucinda.

    The espresso process extracts 65% of the beans caffeine as opposed to 100% as the drip brewers do. More information here: http://coffeesnobs.com.au/YaBB.pl?num=1115516893/29#29
