    Kopi Luwak - First attempt

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Hi All,
    I have been roasting for about 3 years now - 6 months ago I invested in 500g of KL and tonight was the first attempt at roasting - I had planned this and lately I had been practicing on less expensive coffee till I felt I was sufficiently experienced to start the KL in my modified Popper.

    Results are as below;

    T ambient - 18C in Brisbane Humidity 47%

    Time Temp ( Deg C) ( Bean Temp)
    1m 109
    2 163
    3 181
    4 188
    5 192
    6 193.6
    7 195
    8 195.7
    9 195.8
    10 196.3
    11 201.3
    12 207.1
    13 210.3
    14 210
    15 209.7
    15m30 209.5 Stopped Roast.

    NB Note that from 14 minutes the bean temperature started dropping.

    I did not hear any cracks - no first ot second crack, and at the end of the roast I discovered 4 beans that were still green?

    Any advice or pointers welcome.

    Thanks,

    I have been using poppers since 96 and just love them. I still have one of my first Black and Decker poppers. Despite your temperature profile looking excellent, I worry that you didnt have enough bean mass for an effective roast. My minimum has always been 90-100grams irrespective of variety. Otherwise the beans can not get hot enough in this type of roaster, despite temp probe readings to the contrary. Good luck with the next roast.

    Thanks Brett - Ill try it next week.
    I first want to wait a few days before grinding and brewing.
    Im still puzzled at the 4 green beans at the end of the roast though.

    I agree with increasing your batch size, a couple of times recently i was roasting Java at about 60-70g and there was no prominant first crack...on the next roast i increase the batch to 90-100g and first crack is a loud snap and also can easily hear second crack crackles.

    Also by fitting a custom (beer can or soup can) chimney about 10-15cm long it will help contain the heat and gives you the option to increase your batch if the timing is still off!
