Re: Sumatra Mandheling
Hi baconmeister and all
Looks like baconmeisters times and mine agree for the Gene up to SC (230C, FC 12.5 & SC 16.0) but baconmeister then droped temp again to 220 and continued to rolling SC - this is prob what reduces the acidity. Ill try that this weekend.
Thanks, Mike

Re: Sumatra Mandheling
Hi all
Just finished roast No 2 of Sumatra Mandheling same roasting times as the first batch but the first and second crack came in at a lower temp rolling first crack at 165*through to second crack 190* and smoking, This time there where some very dark beans in the batch that I picked out not shore if this is normal fore this bean but if they are as good as the first roast I will be very happy...
Cheers Gra..

I did the Mandheling on 27 Sept in Gene and wasnt that pleased with it.
Temp set to 230C, reached 230C before FC, FC at 12.5 mins so higher temp than ajayro. He didnt say how long it took to get to FC.
My SC was at 16.0 mins, and I ended right on start of SC.
CS 9-10 as there were some light & dark beans in the roast.
The taste was a bit acidic for me, and citrusy. No strong body or earthyness. Not good as an espresso.
Suggestions as to how to vary the roast to reduce citrus/acid and enhance body/earth appreciated.
Mike
Hey Mike, I roasted my batch in the GeneCafe with no preheat and dialed to max 250C unrestrained heat, until FC at around 12mins, turn down to 230c at rolling FC about 12:30. Got to 2nd crack rather quickly for this one at about 16min, turn down heat further to 220c until rolling 2nd crack at about 17:30. Emergency stop and cool with custom built bean cooler to room temp in about 3 mins.
I roast only based on noise and smell, but I would say it should be about CS9-10 but Mandheling is usually a bit light in colour anyway.
I didnt detect much acid with my roast and it was a truly classic Mandheling. Hope my notes helps.

These are a relatively "soft" bean from my experience mate, so as a result I normally stretch the roast out a bit more than what you have done there with Rolling FC happening at anywhere between 12-14 minutes and just touching on the first few snaps of SC about 4-6 minutes after that... going for the longer durations with gentler temperature gradients really seems to suit this bean.
Cheers mate,
Mal.

Re: Sumatra Mandheling
I didnt record how long it took to FC, but I think it was about 16 mins. I roasted outside and it was a bit cold and windy, so the Gene took a while to reach temperature. The temp was set to 235°C, but FC started at 220°C.
Havent tried the coffee yet: will try today.

Re: Sumatra Mandheling
Just roasted some of these today. My second roast in a Gene (thanks Fulcrum). My roast seems on par with everybody. FC at about 220°C and SC only two minutes behind. Pulled when in rolling SC and starting to smoke quite a bit. I let the Gene cool it down to 60°C. Looks very nice, about CS9-10. Will try in a couple of days.

Re: Sumatra Mandheling
That pretty much describes my roast as well (taken into rolling SC).
Im at 5 days post roast and its getting very interesting. A very good bean indeed. Im glad I bit the bullet and scored some of this.

Re: Sumatra Mandheling
I have just tried a cup of Takengon from the last bean bay. Roasted to Rolling 2nd crack.
A very Classic Mandheling indeed, Earthy, mossy, Bitter Sweet, little bit of Vanilla and Caramel, and of course a nice strong Body.
A Good find Andy!

Hi All
Just roasted some Sumatra Mandheling takengon Organic slow run up to first crack 15.00 minutes @ 190o and it appeared to roll through to second crack without stopping I pulled it at 215o CS9 CS10 it looks good but the proof will be in the cupping, Will let it rest for about 4 day before I try.
