Interesting. I'll have to ask my roaster what he thinks about that. This could solve the 3-6 month problem. :)

I spoke to my roaster. She was opposed to freezing already roasted beans (in general) and didn't know about air-tight, evacuated bags.

i said it's controversial. but did she offer you a better solution for long time storage of roasted beans?

No. She didn't have one. That doesn't mean there isn't one. And, I've been thinking about getting one of those vacuum sealers so this is one more reason to get one. :)

I tested sealed bags of beans in the freezer vs. cabinet using the triangle test. Opening bags to test after a couple days and more bags after 4 weeks, nobody could distinguish frozen vs. cabinet beans. After 12 weeks, everyone could easily tell. The frozen beans lasted quite well. In informal testing, frozen beans do degrade by 6 months.

from what I recall in reading is that as long as frozen beans are kept sealed until use, this freezing should work fine. Where it goes wrong is using frozen beans daily. It's the action of opening the frozen beans in a warm environment, using some and then putting them back into the freezer is where it all goes wrong. Something about moisture and condensation.

No. In my city apartment I don't have propane. The rational is that should NYC ever get to the point where electricity, gas, water and garbage pick-up stops happening we're truly in a SHTF scenario. At that point I will be with my family far away from NYC And, if I'm not, I've got far more serious problems then being without coffee.

The green coffee solution is very interesting. I've been thinking about home roasting coffee for a while now. ... This is a very interesting idea. Thx.

Vacuum sealing it yourself is a great way to preserve coffee beans. Once you invest in the vacuum sealer (I got a used one on Craig's List), you can vacuum seal a lot of things for your disaster prep.

<p>(This is probably an opinion question.)</p>

<p>With the coronavirus I've been stocking up on foods that last, and that I like to eat.  Example, I love figs and dried fruit and eat them daily so I've bought three months worth.  I don't like canned sardines so I didn't stock up on that as I would never eat them unless I was under duress.</p>

<p>So the thought went to coffee. I buy my coffee from a local roaster with a store a few blocks from where I live. As a result I don't buy a lot of coffee at one time. In my experience coffee beans are at their best for about two weeks after roasting and start losing their flavor after about a month.</p>

<p>So - and this is an opinion question: How best to provide for a three to six month shortage.</p>

<ol>
<li>Buy beans and have them get stale OR</li>
<li>Buy packaged coffee: Cafe Bustello or illy?</li>
</ol>

<p>Yeah. I know. People are dying and hurting and I'm concerned about sitting around in my apartment without any coffee. Chances are this will not be the Zombie Apocalypse; nor will it be a major pandemic outside of China. </p>

<p>But the question remains - how best to stock up for 3-6 months AND not "waste" ones money buying things that one would not use under normal conditions?</p>

<p><strong>TL/DR - After 6 months storage which would be superior - buying cans of illy or freshly roasted beans stored in a bail lid jars?</strong></p>

# Coffee choices for Zombie Apocalypse

(Asked by: username_0 on 2020-02-18)

(This is probably an opinion question.)

With the coronavirus I've been stocking up on foods that last, and that I like to eat. Example, I love figs and dried fruit and eat them daily so I've bought three monusername_2 worth. I don't like canned sardines so I didn't stock up on that as I would never eat them unless I was under duress.

So the thought went to coffee. I buy my coffee from a local roaster with a store a few blocks from where I live. As a result I don't buy a lot of coffee at one time. In my experience coffee beans are at their best for about two weeks after roasting and start losing their flavor after about a month.

So - and this is an opinion question: How best to provide for a three to six month shortage.

1. Buy beans and have them get stale OR
2. Buy packaged coffee: Cafe Bustello or illy?

Yeah. I know. People are dying and hurting and I'm concerned about sitting around in my apartment without any coffee. Chances are this will not be the Zombie Apocalypse; nor will it be a major pandemic outside of China.

But the question remains - how best to stock up for 3-6 monusername_2 AND not "waste" ones money buying things that one would not use under normal conditions?

**TL/DR - After 6 monusername_2 storage which would be superior - buying cans of illy or freshly roasted beans stored in a bail lid jars?**

Freshly roasted beans start degrading after a week or so. Maybe buying cans of beans - ground or not - would be your best choice for drinking not so great coffee during the end days. Check that they "vacuum pack". Maybe that helps.

I would make another choice: properly stored **green** coffee beans can last for year. Then I would roast it (your going to have filled propane tanks, right?). You can roast a *lot* of coffee from one 5 gal propane tank.

That is my selected choice and I am prepared.
