Perhaps this has been explored before, but in talking with a friend about his home beer brewing endeavors; he is starting to germinate his grains before he roasts them. I wonder if anyone has tried to germinate their coffee before they roast it and what it would do to the sugars and thus the end cup. Anyone heard or tried?

Tried it. Failed. Researched. Found out green beans as we have them are not viable. You need greens in parchment and then it's hit or miss.

I have had the radicle emerge on just about every bean type I tried to germinate. The only beans that ever sprouted for me were still in parchment. But this also is the beginning of the decaffeination process so I'm not sure it will result in a better coffee. Elements were definitely leached out of the beans during the soaking. Try it! Let us know...

Would this be similar to monsooned coffees from Indonesia? On Apr 8, 2013, at 7:36 AM, kevin creason wrote: <Snip> Homeroast mailing list Homeroasthttp://lists.sweetmariascoffee.com/mailman/listinfo/homeroast_lists.sweetmariascoffee.comSweet Maria's Forum Our new Coffee Library |
As with Kevin's results, EVERY bean I have soaked has shot out its radicle (initial root tip), except for Monsooned Malabar...which simply got wet and then began to decay. Unfortunately, I did not continue the sprouting until they began to separate and display their cotyledons and initial leaves. I may do that this summer. Why soak them, you ask? I thought I head someone ask... Last summer I started an experiment to extract proteins from green coffee and analyze differences between growing regions (Costa Rica, Guatemala, Brazil, India, Ethiopia, Yemen, Sumatra) and between a small number of "types" (Bourbon, Typica, Caturra, and "unknown"), I soaked greens overnight, 24 hours, 48 hours, & 72 hours. ALL (except the monsooned) beans from a dozen or so kinds of beans sprouted their radicles within 72 hours -- most before 48 hours. Every bean. After 72 hours, I put beans in the fridge to prevent further development and to reduce spoilage. Ultimately, my experiment was a bust because even the soaked seeds defied easy pulverization by means available to me. To squash the green beans, I had to hammer them using a 16-oz hammer to strike and a 4-lb sledge hammer as an anvil. It was kinda fun...but the end results were both a mess and the extraction required finer "grinding" than I was able to provide, given the tools in the lab. I was NOT about to bring in my coffee grinder to do this. A whirly-blade grinder did NOT work. Those beans are just too hard, yet have some give so they won't shatter like a roasted bean. In the future I will flash freeze beans in liquid Nitrogen and pulverize in a ball mill -- if I can get someone near the lab to part with theirs for a few hours. Now you've got me wanting to sprout a bunch of beans to see how many I can get to leaf out!

Was your in or out of parchment? At 07:27 AM 4/8/2013, you wrote: <Snip> Homeroast mailing list Homeroasthttp://lists.sweetmariascoffee.com/mailman/listinfo/homeroast_lists.sweetmariascoffee.comSweet Maria's Forum Our new Coffee Library |
All were out of parchment. I bought some of the in-parchment greens a couple years ago, but I never tried to sprout those.
