I've been roasting my own beans for almost 10 years now...... and have been using a Pavoni Profesional small expresso machine for over 25 years.... 6 coffees a day... (2 cups ... 3 times)....Madcap grinder.
I take it away camping with me.... runs off a inverter/lithium setup.
Green coffee beans are good for a year..... once roasted and rested for 3-7 days.... ground imediately before use.... then the roasted bean has ideal 7 day window to consume.... if I've done say 3 weeks worth..... by the end of the second week I need to adjust to a finer grind to keep the extraction time about right. I order about 25lbs of green beens twice per year.
I started roasting with modified popcorn makers...... now I use a modified bread maker to stir the beans with an electronic hot air gun ..... about 1lb of beens at a time.
I wheel this setup out of the shed (old cleaners trolley) and roast.... old duct fan sucks smoke and chaff away.... once beens are roasted then I place them in front of the fan to get cooled quickly... in a colander.
Generally, you loose 20% by weight of coffee by roasting.... so need 1.2lbs of green beens to get 1 lb of roasted coffee.
My wife and I preffer different coffee..... so 2 roasts about every 2 to 3 weeks for us.
