  • How much roasted beans to buy ???

    ok, im fairly new to this grinding freshly roasted beens caper, so excuse my ignorance :-/

    my question is, how much roasted beans should i buy in order for it not to go stale before i use it? i will be having 2 double shot espressos a day, and im told that freshly roasted beans remain fresh for 3 weeks.

    now again, i may be wrong, but if 18g makes a double shot and i have 2 per day, thats 36g a day, which roughly equates to 750g every 3 weeks. so should i be buying 750g of roasted beans every 3 weeks? more or less? im prpbably way off..

    also, im told that roasted beans remain fresh if kept in the freezer...is this right? if so, do i have to return the beans to room temperature before grinding/extracting?

    finally, in the eastern suburbs of sydney ive found Alchemy and DiBartolis...anywhere lse i should be visiting?

    Cheers,
    Joe

    Your usage appears similar to mine, about 250g per week.

    So Id say you just have to decide how often you can purchase.
    Im quite happy at the moment to purchase weekly or fortnightly.

    If I buy per fortnight I get some roasted that day or so and some a little older to use straight away.

    No need for the freezer. Just store somwhere dark and cool.
    Freezing could lead to dampness upon thawing.

    I havent tried DiBartolis yet.
    Coffee Alchemy has been good for me.

      thundergod,

      can you not use beans that have been roasted that day? do they have to rest ?

        Beans have to degas normally for atleast 24 hours. Some beans taste better when they have a longer rest period though. Some people have the view that beans should be consumed in the first werk. But it will really be a trial to see what you like. You may find the first batch you get you will notice change in the taste as it ages. Maybe for better or maybe for worse. You will get to know it though and work it out from there, what will suit your needs.
        You will need to allow for a bit of waste as well when you start grinding. Is well worth it though. I am sure when you go to buy them from your roaster they will give you insight into the particular blend you decide on. They may even make you a cup or more so you can sample what you like.

          I havent tried anything under 48 hours.

          The first batch I bought from Coffee Alchemy was probably only a couple of days from roasted when I bought it for my brand new machine.

          It was definitely good to my taste but by about days 8 and 9 I was getting comments from the family about how good the coffee was.

          Now I have been putting it down to improvements in the coffee.
          I cant see that I improved that much that first week.

          Since then I generally dont touch that blend until at least day 7.

          Anyway, this week I have been trying the same blend but have been tasting it daily from day 2 to test my theory that it was the coffee improving with age post roast.

          I have even stretched using it at up to 3 weeks with a small drop in quality in the 3rd week.

          I do prefer to use it within 2 weeks of roasting.

          I have started roasting a little bit myself now at home, and as I said I leave it for at least 2 days.
          I managed to leave one batch for almost a week and it was good too.
          Im still getting the hang of it but as I only need to roast a small batch for emergencies and for now as a learning exercise, its all good fun and so far all drinkable.

            GDay SLUGGO33X and welcome to CS.

            The only way most beans will stay fresh for 3 weeks is if they are packaged in an airtight/one-way valve container shortly after roasting which is then not opened during the 3 weeks.

            Most coffees are noticably stale after a week to ten days under daily usage conditions.

            If youre going to buy roasted beans I would make sure theyre freshly roasted and I wouldnt buy more than a weeks worth.

            Most beans need 24-48 hours of degassing time before theyre ready for use and will hit peak flavor between 3 and 5 days from roasting.

            How the beans are stored has a direct effect on when they reach peak flavor as well as when they go stale. The more air they are exposed too the faster they will reach peak flavor and the faster they will go stale.

              thanks for the replies.

              I just had a chat with the barista at my favourite cafe in sydney, and he also suggested buying 250g packs and storing them in the freezer to ensure freshness.

              They receive a delivery of fresh roasted beans weekly from their supplier, and only sell 250g one way valve packs for $9...reasonable.

              now as to the type of bean, i explained to him that i only every drink double machs at home, and like a strong flavour, so he quickly suggested a SUMATRAN bean for full flavour. Anyone care to comment?

                Good advice

                storing them in the freezer to ensure freshness.
                extreamely poor advice.... [smiley=thumbdown.gif]

                Coffee should be stored in a cool dark DRY place... moisture is one of the enemies of coffee...

                Every time you take the packet out of the freezer moisture will condense..... you then have moist coffee grounds which will go off quickly!

                Bag with a one way valve in the back of a cupboard where its cool (and no strong aromas - like garlic - coffee is good ad absorbing flavours and aromas) is the best.

                  Heartily seconded! Buy only enough freshly roasted beans to last you a week. That way theres no need for freezing.

                    If it your favourite cafe it will give you a good excuse to go there for a cup and buy a bag a week. That way there will be no need to store the beans for any great length anyway. The fresher they are the happier you will be anyway. Seems an okay price for 250grams as long as they are good quality. I have always paid around the 10-13 dollar mark when I have bought 250 and they have been good. If you drink their coffee and like it, it should be a winner for you. In Sydney there are a number of good roasters. I am sure Di Bartoli would look after you in bean selection to help you find one you like from their range.

                      it does make sense that beans will attract moisture when stored in the freezer, but he tells me that this is how the Australian Barista Champ (he mentioned the name, but i cant remember...Paul...) recommends they be stored.

                      Anyway, i currently keep coffee in an airtight container at the bottom of the cupboard, so i will continue doing so.

                      I will sample the Sumatran blend tomorrow...cant wait!

                        IMHO - nothing ever tastes as good after it has been frozen, as it did before it was frozen. Bread, steaks, vegetables, coke, milk etc ...

                        Im no expert in food sciences, but I imagine freezing food only "freezes" (ie converts from liquid to solid) the water in what is being frozen, while the solid part of it is merely being stored at a lower temperature.

                        Anyway, technical logic aside, there probably are exceptions to my "stuff tastes better if it isnt frozen" rule, but I dont think coffee should be one of them

                          Heres a link to an article about Paul Bassett just after he won the world championship:

                          Definitely says "not the fridge or freezer".

                            Thanks for the info regarding storage, I was about to ask that myself as I have noticed that my beans taste better if just stored in an airtight jar in the cupboard (its an old Illy container).

                            Today I bought some 3/4 roast Costa Rican @$6 for 200g. That is my weekly supply.

                              Freezing coffee beans is a contentious issue, especially the brown stuff (roasted). Ive got access to some great roasters here in Melbourne so my turnover is ~5 days. Its part of my weeks food shopping. Ive had Coffee Alchemys beans from Sydney and they were great. Campos, Single Origin, Numero Uno, Di Lorenzo, Tobys all should be able to deliver a properly roasted product. (reminds me that I need to get of my ass and start ordering from interstate. Just to taste... Dont wanna become too Melbourne-centric

                              Ive tried freezing. Bought one of the above last xmas when I was overseas. Had a bundle of fresh roasted beans (3 days post roast+air travel) so I vacuum sealed and froze it a dedicated freezer... 4 weeks later, the beans were aromatically and flavour-wise better than stuff sitting out for the same time in 80% humidity, 36C room temp. BUT still very flat. It was also a real bitch trying to thaw them out in a slow manner. Take em straight out of the freezer and they sweated.


                              With regards to green beans George Howell (Terroir Coffee) is a proponent of freezing. His Kenya (Mamuto, Kirinyaga) is the first of this style of green storage and some good initial consumer feedback.
