How much caffeine is in decaf coffee?

In the United States federal regulations require that in order to label coffee as "decaffeinated" that coffee must have had its caffeine level reduced by no less than 97.5 percent.

Example: Panamanian coffee is about 1.36% caffeine by weight normally. This and many other arabica coffees are about 98.64% caffeine free even before anything is done to lower the caffeine content..

When 97% of the caffeine has been removed only .0408 % of the coffee weight is caffeine. About 4/100ths of 1%. At this level it is labeled "decaffeinated. How roasters label their products is another matter. Suppose two roasters roast Panama coffee that originally came from the same lot, and were decaffeinated together in the same vat. One roaster labels his decaf. "97.5% Caffeine Removed." The other says his is "99+% Caffeine Free." Which roaster is not telling the truth?

The answer is: They are both right. They are both essentially saying the same thing.

Decaf should range somewhere in the 2-4 milligrams of caffeine per cup range.

Currently used solvents for decaffeinating coffee include, H2O (water), CO2 (Carbon Dioxide), Meth. Chloride, Ethyl Acetate. Note: A relatively new method called Swiss Water Decaffeinated uses "flavor-charged" water in the decaffeinating process.


While caffeine is probably

While caffeine is probably not the cause; it has been known and proven to aggravate cases of anxiety (sometimes to severe levels).

Even decaf has caffeine

I believe that even decaf can cause slight headaches.
I used to drink normal coffee at work (1-2 large mugs = 2-4 cups a day). On weekends, I would get headaches. But I noticed that even when I have decaf (2-3 mugs a day), I end up having these headaches whenever I reduce my coffee intake.

It's possible.  Depends on

It's possible.  Depends on your level of sensitivity to caffeine. 
To be classified as decaf; technically it needs to have 97% or more of the caffeine content by weight removed.  So the caffeine levels are pretty tiny but it's not completely removed.

Slight Headache Issue

I also suffer from caffeine withdraw headaches. It's strange because I don't drink regular coffee because of my GERD issues. But today, for the first time ever, I thought I would try decaf just because I love the smell of coffee and before my GERD was diagnosed, I did enjoy a good cup of Joe. Decaf tastes burnt to me, and now I don't feel well just the same as with normal coffee. I won't be drinking coffee or high caffinated tea again.

I also suffer from GERD and

I also suffer from GERD and recently needed to cut regular coffee out of my diet.  I am going to try a couple of the decaf brands that another user recommended and see what I think though.
"I have never liked decaf, but since getting my Keurig, I've found several very good brands nd flavors.  Timothy's Columbian Decaf is terrific as well as Green Mountain Decaf Hazelnut (and I hate haselnut.)  Good Luck."

Although I love coffee and

Although I love coffee and caffeinated drinks, I recently discoverd that by drinking coffee in the morning, it was reason for excessive my tiredness and lethargy later in the day. If you get bouts of tiredness through the day, consider quitting coffee for 30 days - You'll be pleasantly surprised!

PM lethargy

I too tried this with similar results. However I have a theory that it's not actually having the coffee in the morning that makes you tired in the afternoon - since coffee dehydrates the body, if we fail to replenish the lost water we will feel tired. You can test this ... The next time you feel tired in the PM try drinking a glass of two of water - you will be surprised just how awake you begin to feel shortly after.

An apple is actually more

An apple is actually more effective at wakeing you up in the morning than that cup of coffee and its healthier for you. If you're having trouble waking up, try snaking on an apple!

Sex is actually more, than an apple

Sex with or without a partner will wake you up more than an apple, but neither is better than coffee.
