Roasting assistance please....

Hi Louis, Sam 21, and JohnB Louis, our voltage is 240 volts as is that in Tawain, so you might have something there. I have done roasts dropping in up to 200c without tipping/burning etc. and the roaster behaves similar to the early stages of Italyhound's profile. You are right about new vrs older f...

Roasting assistance please....

Hi Evan, I enjoy the process of improving roasts by recording all the factors that impact on a roast, cupping the result, modifying one variable, and re-roasting the same bean followed by further cupping and comparing. Sometimes there are only one or two points between the roasts, occasionally a big...

Roasting assistance please....

Hi Italyhound, Options, options... At the recommendation of a local Hottop buff who has demonstrated some very tasty roasts with beans I previously had difficulty with, I am currently trying roasts with power down to 70% fan 3, two minutes before first.....power down to 60% fan 4, one minute before ...

Hottop Roast Feedback

Sam, looking at your first post, the fan use is somewhat similar to that suggested by the Australia Hottop agent....and demonstrated in his roasts. Load temps and roast times are different. Guess you are on a winner. JL

Hottop Roast Feedback

Notwithstanding earlier thoughts, I am beginning to find that there are differences in profile and subsequent bean taste using the Hottop stock filter combined with higher fan speeds in the ramp up stage before first crack. Presumably the Hottop was designed to be used with its stock filter and I am...

Quest M3 Roast Feedback

Can't comment on the Quest fan as the roaster is not yet approved for use in Australia....electricals I understand. Contrary to earlier thoughts, I am beginning to find that using the Hottop fan on higher settings with a stock filter from 160c through 190c, can alter roast profile and subsequent bea...

Beans in at 75c (beep que) Early drying phase Mid roast ramp tapering off all the ti...

Hottop Roast Feedback

Thanks Rob, makes sense. John, agree that you could roast at 80% and close the chute. I cannot expand on the logic of chute ajar as I am not overly technical. As explained, I borrowed the idea from a course given by a presenter with many years roasting experience, and cupping confirms it works...for...

Hottop Roast Feedback

Hi Sam, John, Rob, About two years ago, I did a roasting course with a National coffee roaster/retailer here in Australia. Apart from their 'big' roasters, we did a few roasts on a HottopB which was being used as a sampler. The course presenter (many years experience) had a whole bunch of tricks usi...
