Topic: Long Term Storage Question -Great Thread! (2 msgs / 81 lines)
1) From: Tom & Maria - Sweet Maria's Coffee
No small grainpro bags yet, although I am wondering if the bags sold 
to keep produce fresher in the fridge have similar properties (?). We 
have 1000 GrainPro bags here for our use, and I take them to origin 
countries to give to our producers to pack our coffee, since one of 
the great benefits comes as the coffee heads down from the mountains 
to muggy port cities, and during ocean transport. We also did a test 
with 4 mil USDA/FDA approved bags but GrainPro bags were slightly 
better. Vacuum packing results have been slightly better than GPs, 
but not extraordinarily better, and for the mills we work with, the 
GP is so easy to use. VP requires equipment, expensive bags (well, 
GPs arent cheap either, really, for a plastic bag) and lots of boxes 
too. GP bags just line the current jute bag on the inside.
Let me point out that it is not a cure-all, and nothing preserves 
coffee indefinitely. The benefits are much better from some origins 
than others. Dry Process coffees shluld only be packaged this way in 
special circumstances. GP and Vac Pack can DAMAGE DP coffees, and 
ones that have not undergone a full rest in parchment (reposo). If 
the coffee has high water activity, it will harm the cup quality. (I 
would delve into this more but I have a fulld ay of roasting samples 
and cupping! we are saving up for our own water activity meter for 
sweet marias, they are pricey!) . Anyway, as far as GP we feel they 
add 3-6 months  to the shelf life, conservatively, Vac pack has 
longer term benefits if they are multi-laminate bags ... 9 months. 
It's been great for us since we have these really expensive coffees 
in vac packing, the $100+ Esmeralda we still have, and the $80 
Guatemala CoE #1. I cup them regularly and they are stellar. So you 
can imagine how grateful I am to the positive effects of Vac Bagging.
By the way, Mike McKoffee is the earliest advocate of vac packing and 
I own him a debt of gratitude.
Freezing coffee - nooooo..... under perfect conditions, commercial 
freezer, thawing before roasting ... sure. But chance of damage to 
coffee is too great... I ove George Howell but disagree with him on 
this point. And in the final analysis, there is NOTHING like fresh, 
new crop , properly rested coffee
Off to cup ....
Tom
PS: yes, we are updating our very old Green Coffee Storage page to 
refelct our new attitudes. But breathable cloth or paper bags are 
still a great option in mild climates where greens will be used in 
6-8 months from arrival.

Tom,
Thank you for weighing in on this topic. When you have a water activity
meter we will all learn much more.
Best Regards,
Eric Faust
