why pay for the roaster to roast it for you if it can be done so easily.
Positive Product Points
very even roast if follow guideline on the manual precisely (weigh your beans)
Negative Product Points
loud, very loud look, it's not very impressive, but who cares if it gives quality roast
i was considering between Hottop and Rosto. i would give Rosto a chance because it's cheaper. after reading Ken Davids' book, i'm aware of the characteristic of fluid bed roaster. after reading some posts from here and sweet maria's, i notice that i should obtain a variac too. i went ahead and got everything in hand.
i've tried two batches without variac so far, both i roasted into full city and full city plus without any problem. the roasts are incredibly even. i've tried another two batches with variac too, the roast profile must be working out and i must get a decent thermometer before i can comment about it. if you don't really want to experiment and mess up with things, just use it according to the manual, you'll get good result.
however, the two roasts without variac have shown the character of fluid bed roasting, very bright and incredibly aftertaste. coffee varietal distinction is very clear. since i roast low quality dry process bean, it shows obvious grassy, baggy, earthy aroma (not really sure which of those) which i rarely got it when i bought from quality drum roaster. i'm waiting for beans from sweet marias, and will give it a try.
cleaning up is easy, use tissue paper to wipe excess oil, and use small automotive type vaccuum cleaner to clean the chaff.
great, easy without any problem. i got it shipped by fast air courier network (EMS).
