Subject: Roast-Grind-Brew Machines

Hello together,

my name is Florence, i am living in Paris and i am starting to collect experience in coffee tastes. A few weeks ago i found an newspaper article about a startup called Bonaverde from Germany. They are or they want to produce a machine which can roast, grind and brew beans for a good "taste". Ok i know that they got maybe a another understanding of taste than I do, but they are promising to have the first machine of this type. Later i found an other article which talks about some UNIMAX machines which did the same couple of years ago. Now my question is if there are more Companys or had been Companys which also produced machine that can handle this roast, grind and brewing process?

I don't find this type of machine appealing.  It would be more for show than for coffee excellence.

  1. Coffee takes 20 minutes to roast, at least 10 minutes to cool down.  In general this requires lots of heat and extra ventilation, more conducive to a kitchen than a brew counter.
  2. Roasted coffee in general should rest at least a day, often more depending on planned brewing style (e.g., espresso generally does better with more rest).  Why connect the two if you're not brewing what you're roasting on the same day?
  3. Combining functions into one machine makes it more specialized, and thus harder to repair and more expensive to maintain, because all the parts work together and anything in the chain causes it to become generally useless.  For example, if the grinder breaks, does that mean I have to wait until that part of the chain is fixed by a machine specialist before I can have a cup?
  4. This type of chain machine will brew only one style.  Do I have to buy a separate one each for espresso vs drip?  Can I siphon off the grinds for a french press?

In lower Manhattan there is a coffee shop with some very push-button machines.  They push a button, and coffee beans can be seen shooting through clear tubes into a grinder that then drops into an espresso machine.  I didn't enjoy my cup.  It was obvious they cared more about the wow factor than anything else.  This do-it-all machine you're reading about seems very much like that kind of operation.

When this machine first appeared on Kickstarter back in November, there was much dissusion as to the concerns and potential issues with it.

Both on CG and on Homeroasters , people have shared their thoughts on it.
