  • How closely do you look at your beans??

    I finally got around to putting some green and roasted beans into the microscope. They are cross sections (i.e. bean broken in half lengthwise) of Indian Tiger Mountain roasted in a popper...

    Unroasted (width of image about 80 microns)


    Roasted (width of image about 1.5 mm)


    Roasted (width of image about 2.5 mm)


    Roasted (width of image about 2 mm)

    Amazing photos

    Do you have one of the roasted bean at 80 microns [smiley=huh.gif]

      interesting photos there. how did u get these photos off a microscope...hooked up to a computer?

        No higher mag of the roasted yet, just a quick look after work so havent put it through all the paces yet...

        The microscope is of the scanning electron variety so its pretty standard to get digital images (although in the old days they did used to take photos of the screen to get their images out!)...

          They are really cool photos, you could mount the bottom one and hang it over your coffee area.

            Could be the future of Coffee Snobbing. Everyone will have electron microscopes and be scrutinizing their grind size down to the nearest micron! ... I think the first picture shows the beans structure to be a bit too rough or "cabbage-like", rather than the preferred "waffle" pattern produced by superior coffee DNA.

              Can anyone else see the face of a man in the bottom left corner?

                Sorry to disagree -- its definitely the face of ET.  Or a bears paw.

                Maybe after a few espressos it will become more clear.

                Seriously, though, very impressive pix Beanmeister.

                  Actually, I think its Jesus. Quick, sell it on e**y.

                    MMMMMmm scanning electron goodness. . .

                    I always seemed to be scanning spores - not as much fun as scanning beans.

                    You should scan a pre-extracted grain of coffee and a post-extraction grain of coffee next!

                      This defines a new level of Coffee Snobbery...

                      Checking out roast beans with an electron microscope!!!

                      And I thought I was over the top with all my techo toys!!

                      Great shots by the way!!!-

                      (now where can I buy a good used -cheap - electron microscope)

                        Hmmm, the words cheap and electron microscope dont really occur together very often!! I will get around to ground coffee images at some stage, at least the particles are small enough so that a whole one should fit into the field of view - beans are way too big when you can only see a couple of millimetres of them at a time...

                          You can build your own Scanning-Tunneling Microscope: http://sxm4.uni-muenster.de/stm-en/ ;D

                          Neat pics Beanmeister!

                            Only problem is that the beans would have to be conductive for STM... [Homer]Mmmm, metallic coffee...[/Homer] I could try and use the STM here but the beans would be a bit rough (and insulating)...

                              Im sure with some roasts that would be fine.... after all charcoal (carbon) is a good conductor ;D ;D
