    Any thoughts on this?

    Maybe on the use of solvents or prospects of naturally low-caffeine.

    What Decaffeination method do you prefer\use?

    • Methylene chloride processing
    • Ethyl acetate processing
    • Carbon dioxide processing
    • Water processing

    How do you know what method was used in the coffee you buy?

    cranberry juices to avoid caffeine.

    I like the taste of coffee but not soda at all. And decaffeinated does the job for me, i really dont think caffeine is all that addicting because my body would realise that it is not getting caffein if it devoloped a desire for it. Of course caffeine is not ideal for the body and effects\alters the cns, if only briefly as i am not aware of any long term effects.

    If I didn't want the caffeine, I'd switch to hot chocolate.

    yeah but it has more sugar than you would get from decaffeinated coffee.

    Indeed. But a piping hot cup of water just doesn't cut it.

    True but a fresh cool glass of water sure is refreshing on a hot day isn't it?

    For a cold drink, water's great. But for some reason, hot drinks require some flavor.

    An additive to water like coffee is OK but adding the sugar is what destroys it. IMO

    I agree. I take my coffee with a little cream, but no sugar. And it must be real cream. I'd rather have it black than with that horrible powdered cream.

    But hot chocolate is really good too.

    Only 4g in the one I posted. Anyway, I drink coffee every day. Hot chocolate? Very rarely.

    If I must use sugar I always use dark brown sugar, its the best as far as

    sugar goes. The light brown isn't to bad either.

    Is there a reason to care, as long as the solvent is gone by the time I drink it? I could imagine that different solvents might wash different other things out of the coffee along with the caffeine, but I have not idea what solvent takes out what, or how it would change the taste.

    Although I suppose one should go with CO2, since it’s surely the better for the environment that ethyl acetate or methylene chloride.

    Chemically Processed food should always be avoided as we do not know whether all chemicals are totally removed are not.
    Many times chemicals used for processing may be harmful even in trace quantities.
    The effect of these chemicals will be known after the prolonged use of these items.
    In short avoid chemical processing and use natural substances.
    If natural substances are harmful then avoid them or minimise their use .

    I don't mind caffeine, it doesn't do anything much to me.

    While we're on the subject of trimethyl xanthine: Why is it that if you have one cup of coffee it makes you hyperactive, if you have like 3/4 your system 'down regulates' and you go back to normal?
