Topic: Some simple questions (4 msgs / 101 lines)
1) From: Timothy Wat
All:
As I think about ramping up volume for holiday gifts, I have some simple
questions:
1.  After roasting and cooling, what general rest time do you use?
2.  Am I correct that the rest period refers to roasted whole bean, prior to
grinding?
3.  How long does roasted whole bean (unground) generally "keep"?  Does
freezing degrade flavor?
4.  Do you usually grind the entire batch of roasted at once?  Or only what
you're going to use for a day or two?
4.  How long does ground coffee "keep" in retaining taste?
5.  Weight - does bean weight increase after roasting?  In other words, if I
purchase 10 lbs. of green, what resultant weight in roasted do I end up
with?
6.  Are there any caveats or problems involved with selling small batches of
the coffee I roast (after the holidays, of course)?
Thanks so much - still trying to learn.

Hi Timothy,
I'll just in with some answers to some of your questions. Others will
be along soon.
1. Usually around 3-7 days, but anything from minutes to weeks can be OK, too.
2. Yes.
3. Around two weeks in my general experience. Three at the outside.
The effect of freezing depends on temperature, any oxygen left in the
bag and howe soon after roasting/degassing it goes in the freezer. I
don't freeze my roasted beans.
4. No. I try to grind immediately prior to use. For work in my
SwissGold One cup brewer, I grind in the morning. There is some
degradation in flavour the longer the ground coffee is kept.
5. No. They decrease - usually by around 15-18%, but they increase in
size by around 60%.
6. Not really. It may be getting stale - depending on how much earlier
you roasted it. For most people any beans you've roasted within the
last month (and not ground) will be better and fresher than
shop-bought beans.
Regards, Gary

1. 2 days is generally recommended, 4 days is supposed to be the best, but
you can enjoy your coffee right after roasting, and taste its flavour
evolution.
2. yes
3. you can call it fres for up to two weeks, even a month if properly
stored, but some beans will lose a lot of aromatics after 10-12 days
4. grind only what you're going to use right away
5. bean size increases after roasting, but you'll lose up to 17% weight due
to water evaporation
6. none that I can think of
Enjoy your homeroasting!

OK, I won't read anyone else's answers first.
For hot coffee, rest at least 36 hours. For iced, it can taste good right
away. For decaf it doesn't seem to matter as much either way. Optimal time
varies from between 60 hours to 5 days, depending on many factors such as
origin and roast depth.
If you have too much roasted beans and can't give it away, try freezing
rather than just letting it stale at room temp. Only freeze what you must,
and do so in portions you'll remove individually from the freezer to use.
Let them warm in the freezing container for an hour before opening and
using.
Only grind what you use, and only just before brewing. The flavor is
discernably different between coffee that's been ground for 1 minute and
coffee that's been ground for half an hour.
Plan on losing 16 to 19 % weight of the beans when you roast, depending on
factors not worth trying to estimate precisely about. Remember that the
beans expand appreciably in size.
The holiday remark is opaque. Say what?
