forgot to mention - that not only do I vacumn the chute and doser, I freeze my beans.
I've got the process down pretty good -
Beans roasted on Monday - I freeze them on Thurs.
Have roughly a days worth in the Major - maybe a day and a half.
Take out half a pound at a time. If you discount days frozen - they are hitting the portafilter roughly 5 to 7 days post roast - maybe eight or nine at the end of a half pound.
Note: I am using a plexiglas tube instead of a hopper. I made a post and pic somewhere on HB - with the tube, and markings on the tube it's pretty easy to tell where you are, in terms of how many shots in the pipeline.
As good as the really great shops are - if you pay attention to detail - you can match them or come damn close if you do everything to a full detail degree. Some may beg to differ, and in fact they may be right. My experience is somewhat limited. Without traveling a great deal, my experience is _going_ to be liimited. Even so, I enjoy delightful coffee at a high level.
