As a home roaster with a large (1kg) roaster at home, my roasting no longer takes as much time as it did when I used consumer level roasters, or even when I (recently) used a 1lb sample roaster. This is a good thing, in my view, in that I can usually find other things to do with my time than to roast coffee.
The majority of the time I use freshly roasted coffee that has not been in the freezer, since when I am home for extended periods I tend to roast more or less weekly. There are times, however, when I absolutely depend upon my freezer stash. For my own consumption, I like to have about 3 - 4 weeks worth of various coffees available in the freezer, all in jars holding 275g or less. My own experience, based upon freezing immediately after the roast and using a very cold chest freezer that is not opened very often, is that I could probably go at least 6 months with these frozen coffees before they would have obviously deteriorated. I don't intentionally degas frozen coffee after taking it out of the freezer. My usual approach is to take it out the day before I use it, mostly to let it come to room temperature, although I have no proof that even this is necessary.
I do roast for some friends, a couple, and for them all the coffee I roast is frozen in valve bags with the valve taped over.
For further clarification, I roast only single origins, and generally dose on the "light side," at 14-16g, tops for a double shot. My typical roast profile is such that I almost never roast into second crack beyond the first second or two. I also do not roast very often for preparations other than espresso. Your mileage may vary based upon what coffees you buy and or roast, and how you prepare them.
