Stale Greens?
How can I tell if my greens have gone stale on me? I forgot about a few 5lb bags from 2 years ago...

Roasted a Yirga and Sidamo from the stash, both were ok but not as distinctly DP African
your greens are fine unless you bought older greens...

roast them and find out...

Green beans will normally last 3 + years in storage
When they are past it they will look very dehydrated and shrunken - hope that helps you with a visual reference
But as Ginny has noted - just roast them

Ginny and KK are correct.

Your greens should be fine... especially if you kept them out of direct sunlight and away from a high humidity environment.

It's a long article but worth the read about storing green coffee and what can ruin your prized stash. It's a reprint of an article in Tea and Coffee Trade Journal that Sweet Marias posted on their site. It gets interesting when you get down to an A-B test done in Ronnoco's "Climate Control Room" under "Warehousing Conditions" heading


I've always noticed more than a slight change in flavor when any of my green coffee's are stored longer than 4-5 months but I'm in Colorado and it's real dry here. Moisture loss (dropping below 12% moisture content) is a big deal and affects much more than just how it reacts in the roaster during the final stages of the roast. It can also have a major negative effect on flavor development even when you've compensated by drying less at the start of the roast. I've just now started storing my greens in Mason jars to try and lessen moisture loss in our dry climate.
