Agreed. Also, some roasters sell their coffee in resealable bags, which means you can just close it and suck out the air through the valve.

I never really trusted the one way valves. The key is being air tight with as little oxygen as possible. I threw a bag straight into the freezer from the roaster. Something tasted off to me after unfreezing that bag.

Oh yes Patrick, I forgot to also say. One should not unpack the coffee immediately. Let it come to room temperature gradually in the jar or bag, otherwise condensation will introduce moisture into the beans which is bad.

I never freeze my beans, or put them in the refrigerator. Should I?

See a couple pages ago. Scott Rao likes it (he once tried his home-roasted beans that his mother kept in the freezer for six years and was overwhelmed with he quality of the brew given the age). There was a double blind study performed by some gents over at home-barista (IIRC) where they tested several factors, including old/new burrs, frozen/fresh beans etc. -- no statistically significant differences. Just, as WiredandTired said, don't refreeze. I'd also put them in the fridge overnight to "acclimatise" then 12 hours or so at room temperature before using them (to get rid of any humidity and such). (edit: just saw that Wiredandtired already wrote it)

@WiredandTired: You're probably right. Either the beans released a lot of CO² or the valves aren't perfectly sealed. Then again, I'm quite certain that a bit of oxygen doesn't make any noteworthy difference. It's with everything, people tend to complicate their hobbies and since the perception is so easily distorted, they think that it actually makes a difference. Best example: a good amount of audiophiles. Anyway, quality ziplock bags should be the best QPR solution.

Is pretty much anything airtight ok, or should I look for one of those CO2 valve release mumbo jumbo things?

Oh man, I struggled with this question for years. Unlike most people on Coffeegeek and Homebarista, I only drink 4 lattes a week so by the time I can go through 12 oz of coffee it is stale. Now I buy 12-16oz of coffee and package them in small, glass, airtight jars with 100 grams (5 shots) each. Then I wrap them numerous times in aluminum foil and saran wrap and store them in the back of my freezer. I've noticed they last months and come out tasting almost as fresh as when they went in. I also have one of those airtight containers that sucks all the c02 out periodically and my experience with it has been crappy so it just sits in the corner nowadays.

idk about putting them in the fridge to acclimatise... that just seems like a condensation nightmare. When freezing the primary goal is to package the beans away from moisture and freeze them as fast as possible. Flash freezing is the best method but no one has such low temperatures in their home freezer.

With the ziplock bags with the zipper thing why can't you zip it up and leave a small gap, suck out the air with your mouth and complete the zip lock thing with your tongue? Seems like a fine solution.

I'm not sure what bean storage method is best, but I don't worry about it. Just buy enough that you can finish it before your own personal time limit (3-4 weeks for me).

Coffee starts to peak at day 9-10. After that, the quality is just downhill. By week 3, it's almost as bad as anything you could find in Safeway.

I did this before I got glass jars. (Glass jars just make the process quicker)

 

I used to bag them twice using that method then wrap in 2 layers of aluminum and 1 layer of saran. I was pretty anal about protecting the coffee from moisture lol

Two levels of foil and bags and saran? 

 

I use a sealed plastic container. 12oz lasts me about 4-5 days, so I don's sweat it that much. Besides, the coffee I tend to buy is Stumptown as that's what the shop across the street sells and they see fit to sell it in a waxed paper bag folded over a few times. Hardly airtight.

You can. I'd use your mouth though, sticking your tongue in the bag not be the optimal solution w/r/t humidity.
Even better would be to use water pressure (like with fake sous vide), that is dump the bag in water until the zipper is almost level with the water surface. The water pressure will press all the air out. Just be careful not to go below water level.

Also be careful not to accidentally breath into the bag, otherwise you should wait a few minutes or so. But as A Y and I've said before, I wouldn't worry too much.

If my bag of coffee can't take anyone breathing in it's general direction it's time to switch to milk.

 

Last week at my cabin: pot of water + pre-ground coffee + added heat until nearly boiled + time to settle = mighty fine coffee.

lefty - that sounds like cowboy coffee. did you throw in an eggshell? we go through about a pound a week, so i don't worry too much about storage. used to keep beans in freezer, but for last year they go in an empty glass peanut jar(?) in a dark cabinet
post #1425 of 2943
I've read that peanut jars aren't proper storage jars. Please use any other jar you can find.
