    Thermos Coffee (Beans) Vacuum Containers

    Cafelat Coffee Tamper and Accessories
    Hi All,

    Just bought a set of these and they seem pretty good. Did a quick search around here but doesnt seem like theres any posts on them so decided to share.

    Im using it to hold Single Origin beans so as soon as I buy them (freshly roasted since I live 5 mins from there) I put them inside and pump out the air.

    According to the box - "the convenient pump mechanism built into the lid ensures air is sucked out of the container rapidly so your coffee retains its freshness and aroma".

    I cant be bothered to go down to Single Origin to buy coffee every couple of days so this seems like a pretty good alternative for those who are super busy like me or who dont live near roasters.

    Has anyone actually had experience with these? Any opinions on how long it can keep the coffee fresh?

    Pics here:

    I put my browns in both Thermos and Vacuvin vacuum containers. Whatever methods I have used I think they lose their punch after about 2 weeks.

    Vacuvin containers and pumps can be bought at Coffee Parts.

    Sounds good from a sales pitch... But not ideal if ya ask me..

    Better with a bag with a one way valve...

    Do a search and you will find plenty about vacc storage and various other shaped containers that do the same thing..

    The beans continue to de-gas..

    Some might say the vacuum even hastens the process

    At some stage the pressure equalises and then you no longer have a seal and the lid can even pop up slightly... *

    Presto... Ya might as well put into a normal container for much less the price. *Or make up a roster and have your self and others apply the pump at various times during the day and night to maintain a vacuum.

    OR

    Use a sensor and hook up to a low voltage fish pump to matain a constant vacuum; regardless of the de gas rate.

    KISS = zip lock bag with a one way valve *;) and squeeze out the air when ya first bag it..

    I kind of gave up on other brands of vacuums since trying infinite other "Thermos" only for drinks to go cold in 3 hrs.
    My experience with proper Thermos is that for drinks, they last past 12hrs and one I have which is really good, keeps warm for 24hrs which is why I kind of automatically trust Thermos original for vacuum products these days.

    I did buy these a couple of years ago. I found they didnt live up to promise and arent the best for storing beans. Quicker loss of flavour was one problem, as others have mentioned..a dn loss of pressure as AM pointed out.

    Use them for storing flour or biscuits or something else other than beans.

    Storing in a 1-way valve bag with the air squeezed out is still the best way for me.

    What is vacuum ?

    What do all thing strive for ? *(And yes electrolytes is one - its what plants crave :-) ) *

    The physics and things being in a balance... Native state of being when at rest.

    A vacuum in the jar is in effect trying to suck things back so that it is in a balance and in the container there are beans that are generating and de gassing... *Now they usually de gas at a nominal rate when at rest in a sealed bag. *

    One might say that as pressure builds... It has the reverse effect and slows down the rate of de gassing.. *But to ensure the pressure does not build to high and split the bag a valve is put in... Thus we have a workable balance, without out excess moisture and Oxygen in play (they are kept out by the bag and the higher pressure within the bag).


    When they are subject to a Vacuum some might say that thus applies forces on the beans and hastens the rate at which they de-gas...

    All I know is that I get better shelf life and better cup outcomes from a well sealed zip lock bag and a one way valve. *Than by freezing or putting in the fridge OR using a container and vacuum pump.

    PS. *Try it... Some good beans in there and pump away... Ya will not get close to a true vacuum (-30) but you will get one of sorts..

    The lid will now be tight.. *Put it away and leave it for the weekend.. Your going away.. *Also use a control lot of beans in a sealed bag...

    If they have degassed (some beans do more than others and depending on the roast as well) - control bag will be nice and bulging... I bet ya lid is loose and will fall off. *Yep ya beans have been exposed to good old fashioned air.

    100% support the comments above.. Something that does not give off a gas and dislike moisture.. Chips / Crisps / Crunchy biscuit when out camping ;)

    Re: Thermos Coffee (Beans) Vacuum Containers

    Interesting... I will experiment and report :)

    Though I must say, as someone who works in kitchens constantly, I keep a tight (and some friends call it "obssessive compulsive") kitchen so I have different places for different storage.. (e.g. my opened red wines will remain unchanged for at least 3 days before deteriorating)
    Not sure if this will come into effect but will check.

    The best way would be to have a system that does a nitrogen flush of the container forcing out the oxygen and leaving the inert nitrogen gas. Same as the most food producers use to store and pack fresh produce these days.

    The highlighted text I believe to be true.

    I havent tried vacuum containers for my beans because I believe the decreased pressure will lead to faster deterioration of the beans as they are forced to degas faster.

    I have though (accidentally) tried the reverse.
    I once had a bag with a faulty valve (lucky it was also heat sealed).
    After a week of storage the bag had blown up like a football.
    The zip-lock popped but the heat seal held.
    Upon trying the beans they tasted very fresh; not like week old beans at all.

    Re: Thermos Coffee (Beans) Vacuum Containers

    I hope this is not OT, if so just delete it. I roast weekly, beans go into one way valve bag for degas[5-7 days generally] then into a Vacuvin canister whilst I use them over a period of a week. This way I dont have a problem with the sealing of the canister providing I keep the seal clean. Is this ideal, probably not but the beans are finished within 14 days post roast.

    Steve.

    In my opinion, not if you suck the air out.
    If you just use it as a container I see no problem.

    Vacuum storage of roasted beans speeds them going flat in flavour so dont do it !
