O.k. here it is...I have a 60 kilo Ambex. I had an order for 17 lbs of a decaf coffee....the least amount I have roasted was 40 lbs....so I did a batch of 20 lbs (shrunk down to 17.5lbs)and it came out perfect..I was shocked that it came out even...no tipping...I think I will try 15 lbs tomorrow...and then maybe 10 lbs...but doubt the 10 lb batch will work...wow I have .5 lbs left over....so I can taste it :wink: cuz I heard someone say you should taste everything you serve
