Topic: home decafeination (3 msgs / 92 lines)
1) From: Tom & Maria - Sweet Maria's Coffee
It's actually a really interesting idea. I wonder if there is a way 
to reduce caffeine in coffee. The neat thing about doing it at home, 
then home roasting is that there might be some factor that is 
impractical in the commercial process that could be workable at home. 
For example, maybe if you used a steaming or water soak, filtration 
(that's the catch- filtration that would remove caffeine), then 
allowed the coffee to re-absorb the flavor, then without re-drying 
you could roast it right away. Follow me? I wonder if filtration used 
for camping, for amoeba and giardia, would have any effect on 
caffeine content.
One thing talked about was the decaf stir stick. It is a physical 
bonding to caffeine that you could simply use in any brewed coffee 
and reduce caffeine. That would be better than any pre-roast decaf 
method.

Anyone you know in the coffee biz that might be able to help work out
a process with us? Or maybe try tweeting the question and someone
might know someone. I'm game to give it try with some suggestions. I
have a family decaf drinker.

I really don't. Most decaf plants are in Germany or Mexico, Swiss 
Water in Vancouver ... We were going to have a coffee done in 
Colombia. I am not sure how much it would help because they don't 
have some sort of "sample decaf" unit to test out a coffee at those 
plants. The only possibilities are going to be a filtration method, 
or maybe, just maybe, Ethyl Acetate. The others are not methods you 
can use. Maybe C0-2 can be done with a can of Schwepps? I doubt it...
