Any thoughts on this?

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

Ethyl acetate processed products are referred to as "naturally decaffeinated" because ethyl acetate is a chemical found naturally in many fruits. Caffeine is extracted in the same way as with methylene chloride processing, but ethyl acetate is the solvent.

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?

Coffea arabica normally contains about half the caffeine of Coffea robusta. A Coffea arabica bean containing little caffeine has been found recently in Ethiopia.[1] This may change how low-caffeine coffee is produced in the future. Additionally, genetic engineering technology may be eventually applied to create a "naturally" caffeine-free coffee. But for now, one of several methods to remove the caffeine from caffeine-containing beans is employed.

I try to drink only water,fresh fruit juices or natural apple, grape or

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.

Not necessarily that much more:

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.

Allot of sugar in that stuff! :eek:

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.

I drink coffee everyday. Medium roast, cream and sugar (raw sugar). I'm hoping to switch to organic coffee by the end of the year (so freaking expensive I have to budget for it... :p ). Nothing like starting my day with a nice hot cup of coffee and sciforums... errr.... work.... :D

Specially if it's snowing outside. All those suckers commuting to work.... HAHAHA!!!!! :D
Just kidding guys...

I hate the powder cream too... YUCK! That stuff must be toxic or something. It taste HORRIBLE! :puke:

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?

I'm still waiting for a hyper-caffeinated brand, like redbull for soft drinks.

Once in high school some friends of mine had a coffee drinking contest. I hadn't been drinking coffee long, so I didn't have much tolerance to it yet. We were at one of those diners where they just keep refilling the cup. I think I drank 12 cups in a row. My body definitely didn't "down regulate". I was super-charged. My stomach didn't feel so great, though.

Ok, maybe I'm just weird then.

Pretty much everything about me is weird, no reason why my autonomic nervous system should miss out :D

I really don't think caffeine is all that addicting because my body would realise that it is not getting caffeine if it devoloped a desire for it.Not all of our bodies react the same way. Caffeine is highly addictive for me, more so than any of the recreational drugs that I--I mean my friend Zeke--experimented with in my--I mean his--adventurous youth. It releases endorphins and makes me happier than I've ever been except for a handful of the true highlights of my life. And then of course there's the inconsolable endorphin-debt that follows.

There's been a separate thread on this but I have ruined my life a couple of times through caffeine addiction. After having some I get an intolerable craving for more the next day, and if I get too strung out I get actual physical symptoms like headache as well as psychological symptoms like being the world's biggest asshole. It also interferes with sleep, making all of these symptoms worse.If I didn't want the caffeine, I'd switch to hot chocolate.Cocoa solids contain a substantial amount of caffeine. Today's boutique dark chocolate bars with their prominently touted cocoa percentages have more than enough caffeine for me to regard them as a dangerous drug. Not that this stops me, especially since my wife is a chocoloatiere. I've just become strong enough to go cold turkey the next day and put up with the physical symptoms and she loves me enough to put up with the behavior.

Cocoa also contains theobroma, another psychoactive drug. The effects of a recently-identified drug like theobroma are not as well studied as legacy drugs like caffeine and alcohol, so we don't know how the effect varies from one person to another. In general, although theobroma is a stimulant, it seems to have a mood-mellowing affect on many people, which counteracts the edge that caffeine often imparts.

This combination of caffeine and theobroma was obviously one of the attractions that motivated the Aztecs to put so much effort into figuring out how to render an ingestible substance out of cocoa beans. As it is, the "chocolatl" they invented would barely qualify as "cocoa bean soup" by modern standards. Nonetheless "cocoa" took Europe by storm, especially augmented by milk and sugar. (The Aztecs couldn't invent "milk chocolate" because there were no dairy animals in the Western Hemisphere.)

It wasn't until the late 19th century that chemical engineering technology allowed the refinement of cocoa into the concentrated, solid form we associate with the word "chocolate" today, with a caffeine content that rivals coffee and tea.

BTW, white chocolate is pure cocoa butter. It has some of the flavor and much of the texture of complete cocoa, but no caffeine.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?You just said caffeine doesn't do anything much to you and now you're saying that coffee makes you hyperactive!

People metabolize caffeine at different rates. I'm very slow, two ounces of cola in a measuring cup keeps me bouncing off the ceiling for two days. Stimulants affect your blood sugar level and can start a chain reaction. By the time you drink the third cup you might be at a low point that more than compensates for the stimulant effect of the caffeine.

I can often drug myself to sleep after a caffeine binge by stuffing myself with dessert before bedtime. About an hour later I experience a crash and fall asleep with my face on the keyboard. My body can regulate itself to stay asleep for a few hours but I wake up early, not terribly well rested, with a craving for more caffeine and an attitude that urges anyone nearby to just give it to me.

It makes me hyperactive if I just have one, but if I have 3/4 I return to normal somehow. Sorry, should have explained better. :D

more so than any of the recreational drugs that I--I mean my friend Zeke--experimented with in my--I mean his--adventurous youth

Haha. I like your style. :D
