Topic: Light degradation of roast coffee (6 msgs / 132 lines)
1) From: Paul Helbert
A month or so ago I started an experiment on light degradation of
roast coffee. We got into a cloudy, rainy spell and forgot about it. I
had painted one jar white and the other was clear glass. It would have
been better to have used glass plates and kept the coffee one bean
layer thick. Both jar lids were fitted with coffee bag vents.
Results: All I did was open and sniff the aroma after a week. The
coffee which had been protected from sunlight by the white paint still
had a nice coffee aroma. The coffee exposed to sunlight seems to have
lost all of its odor. I did not notice any skunky or other off smells.
I could not bring myself, even in the interest of science, to brew and
drink the results.

Paul - Was the clear jar in direct or indirect sunlight?

determine how to degrade roasted coffee.]
My Word! Roasting definitely develops delicate flavor and aroma. Was there
any question that exposure to the elements would degrade the experience?
How about a case of Pinot Noir? You could pull the corks out of 6 of the
bottles, fill  Styrofoam cups from three of them. Ugh...
Then what? You could patent a natural process for making vinegar. I know
nothing, but even I wouldn't try that.

I don't think you're being fair. There's are legitimate questions
here: to what extent does light exposure degrade the quality of the
beans; at what rate does the degradation happen; what about indirect
light vs direct; etc.

I think you have to get to know RayO. He has a certain "style" (maybe
set of styles) all his own. No offense taken.
My fault is in not keeping the thread together from the beginning.
That from laziness.
