    Vacuvin coffee saver vacuum set

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Does anybody use these containers and if so are they good to store beans?

    Hi ragdoll.

    There had been some discussion on this recently but I cant remember the thread it is in for you.

    I have one of these and some of the bottle stoppers as well. I dont have a problem with the cannister, it seems to work well, if you have removed the air properly. However, I dont really store beans in it for very long!

    Re: Vacuvin coffee saver vacuum set

    I have one of these but I dont use it for beans anymore, only for ground coffee that I get from work via a Mini Mazzer E ;).

    I found that the beans tended to weep oil much quicker than if I just used an air tight container. I thought the vacuum might be "extracting" the oils?? I couldnt taste any difference in the coffee either (e.g. for > 4 weeks old beans). Now I simply buy smaller quantities more often *8-)

    Commercial roasters of quality beans place them in aluminium bags with a one way valve.

    From talking to the roaster where I buy my beans - the reason is the beans "gas" for a period of days after roasting..... the one way valve lets the gas out (I think it is CO2) but doesnt let air in.....

    Putting freshly roasted beans under vaccuum would no doubt alter this process (and probably the taste as well).....

    Stale beans might be OK to vaccuum store - but who would want to brew using stale beans?

    You will notice cheap supermarket beans (with an expiry daye >6 months) are often vaccuum packed - must be stale when packed otherwise the gas from the beans would expand the bag!!!

    Re: Vacuvin coffee saver vacuum set

    Hi, Ive only been roasting for a short time, think Im up to roast #14. *I have 2 of these containers and they work well. *I just leave the lid unsealed just sitting on top of the container for the first day or two after the roast then suck the air out and its sealed. *The beans are normally all gone within a week ;), so I dont really know if they are better than anything else, seems to work OK for wine though.

    Ive stuck a fairly big piece of white contact vinyl on the outside of the containers (wraps most of the way around), not only does it block out a lot of light, but I can write on the container what beans I have inside.

    Re: Vacuvin coffee saver vacuum set

    How about chucking the Vacuvin container in the freezer? Alan Frew mentioned somewhere that if vacuum packed, beans may be good for 12 weeks in a chest freezer. Probably good enough then for ones own roasts to sit in the fridges freezer for a couple of weeks. The cold probably will reduce oil leaching out of the beans at the low ambient pressure (because of increased oil viscosity?). Not tried it myself though.

    Re: Vacuvin coffee saver vacuum set

    In my experimenting with vacuum packing here I determined that doing so detracts from the beans aroma and flavor.

    The only reason I can see to vacuum pack your beans is if theyre going to be stored for a long time. And seeing as we roast our own why bother with that when we can have them at their optimum freshness? :)

    Right on, JP.

    Alan Frew mentioned somewhere that if vacuum packed, beans may be good for 12 weeks in a chest freezer.

    Why dont you just try it? I reckon that theyd be pretty damned flat! And dont forget that there will probably be some condensation on the beans after defrosting ...

    From talking to the roaster where I buy my beans - the reason is the beans "gas" for a period of days after roasting..... the one way valve lets the gas out (I think it is CO2) but doesnt let air in.....

    Putting freshly roasted beans under vaccuum would no doubt alter this process (and probably the taste as well).....
    I would have thought that reducing the concentration of gases outside the beans would shift the equilibrium to favour beans outgassing, even though it presumably slows oxidation. Probably not a huge deal if you immediately vac-pack fresh beans until using them a week down the track, because the gases will come out anyway, but if you do it after every use ...

    If you really want to preserve the beans, nitrogen flushing is probably superior.

    Cheers,

    Re: Vacuvin coffee saver vacuum set

    As I buy freshly roasted beans every fortnight or so, I find the Vacuum canister works well for me to keeps as much freshness as possible over that time frame. but the general thing is not for too long.

    Re: Vacuvin coffee saver vacuum set

    i use them for the 3-4 weeks that it takes me to go through a kilo. usually the first week or so the seal breaks, as the beans de-gas.
    it seems to keep them fresh for that long, but by the 4th week they are starting to age.....

    Re: Vacuvin coffee saver vacuum set

    I found that using one (over a 7-9 day period) that the constant vacuuming (break the seal to get beans out, re-vacuum x2 per day) seemed to make the beans stale faster. Whether its sucking the gas out faster, I dunno.

    Ive switched back to using an air tight container, and my coffee is still pretty good by the end of the week, whereas with the vacuum sealed container, they were notably flatter/more stale.

    Re: Vacuvin coffee saver vacuum set

    I think the best way is when you get your batch of beans, leave some out in an air tight container that will last you a few days to a week and seal up the rest in the Coffee Saver. If you have that much that is.

    Re: Vacuvin coffee saver vacuum set

    Im also considering buying one of these.
    I normally use 250g every fortnight, and by the end of the 2nd week the beans are quite stale.
    I generally get them on the post and need to walk a fair bit to the post office not to mention I need to get home from work before 5 just to pick up the coffee beans every two weeks.

    If with this I can somehow manage to make them live a little longer, I could buy in 500gram batches instead.

    any ideas?

    Yeah dont buy one of these for a start while you will remove some air from the beans the negative pressure on them accelerates the oils coming out of the beans and speeds aging :P

    Best bet is to buy a stash of 250g bags from Beanbay and a $40-50 heat sealer from the bay of evil and split your FRESH beans as soon as you get them and heat seal the bags. I just got a 1kg bag from Andy and broke it down into 4 smaller ones when it arrived 3 days post roast for me that is 2-3 weeks usage so I expect the last bag to still taste really good. Rezipped and push out as much air as you can is the easy no fuss way to do it.

    do you think theres any need to bag them?
    any airtight container should do I guess.
    something like a tupperware?

    Only if you can squeeze out any excess air :-?

    Using freezer bags inside the zip bags extends their life considerably.

    Re: Vacuvin coffee saver vacuum set

    Ooops, i didnt think of getting rid of excess air. youre right scarey.

    But with that in mind, wouldnt a vacu vin work well if you dont suck all the air, but left some?

    Re: Vacuvin coffee saver vacuum set

    Problem is that is does leave air and at reduced pressure which is the beans are still degassing is replaced with CO2 and then the Vacuum is gone. Just dont do it, bags are used for a reason.

    Re: Vacuvin coffee saver vacuum set

    How about glass jars with good lids?

    I find the bags a pain- and dont like the waste of a sealing machine, etc.

    I always wonder what the story is with beans when I go to a roaster or bean merchant and see huge amounts of roasted beans stored in large containers with no airtight qualities at all. Is the idea that they turn over the beans so quickly they are never in the bins for more than a few days?

    If you typically roast and drink it all withing say a fortnight is is not really necessary to store beans in the best airtight fashion?

    I suspect the answer is certainly no- but the roasteries make me wonder.

    Re: Vacuvin coffee saver vacuum set

    Nah we were just ignoring you Jack ;)

    Much as we are drifting OT I have generally stopped heat sealing my zip locked valved bags unless I am giving it to someone else (extends the good life if not opened for a week or so) but for my own use just the zip locks do the job.

    Heat sealing of bags if they are being shipped around and handled I reckon is as much about spillage control for us frequent consumers ::)

    I know stumptown uses glass jars with lids and they look quite cool. See http://farm5.static.flickr.com/4127/5009446286_73d125c937.jpg

    Reusable too - maybe we can start a revolution here where we can purchase jars from where we buy our coffee from, fill them up with beans, and bring them back for more coffee when its empty. Much like how KeepCups are being used everywhere these days! :)

    Sorry mods if its going off topic...

    Re: Vacuvin coffee saver vacuum set

    I would not like to hazard any sort of expert opinion on what seems to be a sometimes emotive topic, but I can offer the following anecdotal experiences, which have both Pro and Con aspects:

    1. My sister/brother-in-law have had a speciality coffee roaster in Cape Town for over 18 years, and I was visiting a few weeks ago over there. When I talked about keeping coffee sealed etc, using valved bags, my brother-in-law was a bit non-plussed. Did not see it as a big deal, and does not use valved bags. He was even sceptical about de-gassing periods etc. They are reasonable small, and turn around their coffee quite quickly, and their coffee is excellent. He roasts with a 5kg Fluid bed roaster.

    2. A friend of mine for whom I have been supplying beans for about a year used to buy his beans from a local small roaster here in the Redlands, who has won awards etc. (Has Garanti roaster I think). When I asked him about the difference between what I supply and what he was getting before, his comment was that mine are awlays consistently fresh, wheris before it was a bit hit and miss. They store their beans in shop style bins. I normally roast, blend and seal his beans in a valved bag until he is ready for them, which is *usually within 5 days. Of course my small amounts make it practical to do so, not so easy when you a have larger amounts no doubt. He actually discards my valve bag after opening and stores the beans in one of those Vacuum style cannisters until using.
