    Storing beans in urine sample jars

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    My latest trick is to put my just home roasted beans into plastic urine sample jars to keep them as fresh as possible prior to the point of grinding and brewing. I grind before going to work for the aeropress and the ground coffee goes back into the urine sample jar.

    I have been getting some strange looks at work though.

    THe hitch with this has been that a full container is about 25 grams of beans which is a fair overdose for your average basket. I found some plastic dice which I put into each jar to reduce the volume. 3 dice into the container gives me 18 grams of beans as a dose. 5 dice for 15 grams which is a good dose for the Aeropress.

    I look forward to the general CS opinion re this technique to reduce bean spoilage by air.

    Re: Storing beans in urine sample jars

    Whatever works for you Jason - theres been plenty of novel bean storing ideas broached on this forum.

    Just dont confuse the samples next time you visit your urologist mate ... it could have some nasty unintended consequences for immediate treatment/surgery ordered once the results are known ;D

    Theyre all screw-top, so although your [hopefully sanitised] :P jars hold a requisite grind amount for your needs, they still allow oxygen in, so over time will give you a stale result.

    Just a day each time, & I reckon youre fine - prob no evident loss of freshness. Keep it in there any longer & penetrating air will just eat away gradually at the freshness.

    Sorry for taking the piss with your storage method ;)

    Re: Storing beans in urine sample jars

    Facetious responses were surely expected Jason - youve admitted already to weird looks at your workplace!

    How about storing more volume of beans/grind for your skeptical workplace-mates with a catheter bag for storage?

    ... hopefully air-tight though :o

    I suppose it makes them think twice about pinching your coffee.

    not that I want any, but one would ask why you have such a ready supply of urine sample jars. Of all the things to choose, this is one of the strangest

    haha, I reckon I could use my Impulse sealer on those bags.... oh man, this is a super funny thread.

    I guess the wee bottles would be good in that they seal (youd hope) better than some bottles out there.

    Re: Storing beans in urine sample jars

    THe urine sample jars are a serious proposal!!

    They may be screw top but, naturally, are designed to seal really well. They probably seal better than the ziplock bags. And they are cheap as chips from the chemist

    You may grind on demand but each time you open your ziplock bag you let new air into all your beans. Say if you make 3 coffees a day you are opening your zip lock bag three times a day. Say if it is a 300 gram bag of beans then you are possibly opening your bag 20 times so the last beans have been well exposed to air over a period of a week. Dont you notice the last beans in your bag smelling rather stale! The urine jar system means the beans dont get exposed to any new air between the time they are cooled after roasting and just before they are ground.

    THe other advantage is that your doses are measured out so you dont have to stuff around with scales, scoops and the like. You do have to stuff around with dice though, although the rocky wont let them in to be ground.

    SHort of having a grinder at work, pre grinding into a container that is as small as possible for one cup of coffee seems to be the best compromise.

    Re: Storing beans in urine sample jars

    Sounds like an idea Al - just a couple of points...

    - if youre noticing a stale smell from your coffee bags its an indication that you dont drink enough coffee, and,

    - can we call these sample jars something else - Im getting wee-zy!

    :)

    Re: Storing beans in urine sample jars

    You could also use little Nalgene vials (available at good camping stores) which are perhaps less incongruous than the old wee bottles, but they are 10 times the price.

    Anyway, coffee is actually a Diarrhetic

    I might setup a poll on this; sample jars versus the zip lock bag.

    Re: Storing beans in urine sample jars

    I wonder if you could nitrogen flush those suckers too for extra freshness haha

    "What are you doing?"

    "Just nitrogen flushing my wee bottles so that my pre-ground is fresher.... dont you know?!"

    Re: Storing beans in urine sample jars

    I am amazed at the cynicism out there!

    I thought the extremes CSers go to to keep their beans fresh such as grinding on demand and investing in heat sealers would mean that the idea of individually packaging each dose of beans straight out of the popper would make sense to many. A bit like pods for snobs.

    Re: Storing beans in urine sample jars

    I think it is terrible the way a few contributors are taking the p*ss on this subject.

    Al is obviously dedicated to achieving the taste he wants (eeewwww) in his coffee and I think it is rather unkind that weee (sorry Al) are making fun of this post.

    Maybe Al should try posting a streaming *:P vid of the process so weee can see what he means. *Maybe using some Brazil Yellow Bourbon as an example? *;D

    I mean toilet humour really

    Re: Storing beans in urine sample jars

    People pay alot for those beans that have been pooped out of some rodent in sumatra. Whats wrong with mixing Urology and coffee brewing

    I wish Id left the Urine out of the header...

    Honestly, I think its a good idea...just as long as you dont put mysore nuggets in the jars - they tend to clump. A good peaberry would be ideal.

    And to stop all the jars from cluttering your desk you could store them in a bed pan ;D

    I really hope you mean diuretic. :P

    Anyhoo, sounds like a clever, if somewhat fiddly (the dice factor), idea ...

    Hey, the fresher the better, as all snobs will agree - but Id be saving for a work grinder ;) (But youd still get strange looks for that I suspect)

    Re: Storing beans in urine sample jars

    Al_Capp! I wont knock your thread. Im honestly not surprised theres been a bit of banter but then coming up with an application like this I think you had to expect a bit of that.

    I think the idea certainly has some merit. The main issue I see is how does an airtight container cater for bean degassing? Perhaps there wont be too much degassing in 20g of beans but surely there will be some. Theres also the issue that when you grind you dont always lose the same amount (spillage etc) and you may end up a few beans short. I guess you could just allow an extra couple of grams but then youll get wasteage most of the time.

    I think the principle is good but there are still a couple of questions hanging over it to me.

    Re: Storing beans in urine sample jars

    Greg I disagree re differences in ground amount.
    My grinder gives next to no wastage, so barring spillage as youve suggested, consistancy is possible.
    Spillage can be controlled with care.

    Re: Storing beans in urine sample jars

    Al Capp, if you cant grind at work then what youre doing sounds like a great compromise between freshness and what is practical and convenient. Youre right about zip lock bags not being completely air tight - the wee jars would be less likely to see you having a leak.

    Reminds me of when I once stored fruit juice in a communal fridge at work, where stuff often went missing. I put my pineapple juice, which looked like wee, in an otherwise unmarked bottle with a printed "urine specimen" label on it. People must have suspected it wasnt what the label said, but nobody else drunk from it.
