Hello, I am planning to roast in the garage all year around. Now, I am storing my greens in the garage. In winter it goes really low and I am not sure if bean can support frozing condition.

Hi Sylvain,
Freezing greens is not a problem, but varying/fluctuating temperatures & humidity conditions are. A very famous roaster George Howell of Terroir Coffee fame freezes ALL of their green coffees in a commercial freezer environment at -40C/-40F to preserve their varietal attributes.

One thing to keep in mind is not only storage but roasting as well.
To store in a very cold environment may be beneficial to long term character however if the beans aren't fully defrosted to a reasonable room temp prior to roasting you will have extended roast times and possibly have beans that are unevenly roasted towards the center.
Think any frozen commodity and trying to cook it, be it in a pan, BBQ, broil etc. It will not cook evenly, same would be true of beans.
REMINDER: Never leave the roaster unattended when in use !! And remember to use our Rosetta Stone tip PART V PARAGRAPH 3.. it works !!!

One thing about frozen beans-
When they freeze, some of the internal moisture wicks out and when they thaw the moisture is now on the outside. Thus, it is best to roast as soon as they thaw, or in a pinch dry them out in a low oven or in the sun before storing at room temperature.

Thanks all for the very interesting feedback. I think I will keep the bean inside and roast in the garage. Thats not a big deal but was curious about it.

Sylvain, if you keep the Behmor in the garage, in the winter you will need to warm it up before you roast. It will not start roasting if it is too cold.
I bring mine indoors, open the door, and remove the drum. I let it sit for about 15 minutes to get it to room temperature before I roast.
