I said I would post the results of my continued attempts at roasting the
Sumatra Decaffe KVM bean I obtained in Hayward Wisconsin from u-roast-em.com.
I am not getting good flavor out of this bean.
I want to thank all those on the list, especially Les, who made positive
comments and even have no hard feelings for that individual who exercised his
commendable vocabulary to exemplify his less then stellar level of human
In summery, I think that this bean is lower in quality then any other bean
that I have ever purchased from u-roast-em. I do not purchase more then
about 10 percent of my beans from there and probably will not purchase even
that level in the future. The establishment is down the road from the home
of my mother in law so it makes pick up somewhat convenient. Paying SM the
shipping is clearly worth it.
I have got a good roast from the Sumatra Decaffe KVM bean. I see the problem
as being a combination of extreme dryness and the KVM Decaffe just being
chaff free. This lack of chaff has a profound effect on the iRoast.
I did note the comment about leaving the iRoast with the chaff from a previous
roast not cleaned out of the chaff collector. I choose not to use this
method, although I have the highest respect for the source, mainly because I
strive in all my roasting to achieve a level of consistency consistent with
scientific method and I did not see leaving chaff in the collector as
In the end what worked was a much higher temp roast profile in the iRoast
combined with Less tip of adding moisture to the beans. Here are the
I soaked 10.4 oz of the beans for exactly 5 min in water at 100 degree F.
After 5 min I tossed the beans in a strainer, shook out all excess water, and
drained on paper towel till zero surface moisture could be seen. The beans
where then put in a zip lock bag at room temperature overnight. The
following morning they where taken out of the bag and again placed on clean
paper towel for one hour. The increase in weight due to moisture was noted
as 10.6%. Two 5.2 oz weights where collected and the remaining moisturized
beans where tossed. Each of the two 5.2 oz amounts where roasted in an
iRoast with the following parameters 330:3,410:3,460,5 1/2. This gave a good
Vienna roast with full body and good varietals. I feel this bean is as good
as any Sumatra Decaffe I have ever roasted but that is not a very large lot
as most of what I use is regular coffee.
I hope this comments will prove helpful to others.
