    Roasting notes

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Some big bags of beans arrived at work today for me *:D
    (I think my co-workers are convinced Im importing some "other" green substance inside them)

    So, tonight, it was out with the heat gun and a roasting we go!

    First up, 2 cups of Kenyan AA. *Ive had Kenyan before from another source, and this behaved pretty much the same. *1st crack at 12 mins, 2nd at 17, finish at 18. *Fair bit of chaff, slight uneveness in roast.

    Next, I nervously tried the Yemen. *(One and a quarter cups) This is a tiny bean! *I had to pull the gun back a fair bit to stop them from blowing out of the bowl and they seemed to be roasting too quick as well. *Lots of chaff. *A very weak 1st crack at 10mins followed by a more defined 2nd crack at 15mins. *The roast was quite uneven on this one. *I swear I smelt chocolate at one stage during the roast, but that may well be wishful thinking on my part.

    Third up, the Moonsoon Malabar. *What a contrast in size to the Yemen. *Huge beans that look like peanuts while rosting. *This stuff roasts fast! *I backed off the heat to extend it a bit, and got to a very loud and definite 1st crack at 10mins, which rolled on to 2nd crack at 12. *Roast complete at 13mins. *A surprising amount of chaff considering how clean the beans look. *Again, somewhat uneven roast, and Im starting to question whether my heat gun is going off, or whether its me. *Takes awhile to cool down these large beans as well.

    Lastly, 2 cups of Harrar. *This is more what Im used to. *1st crack at 12 mins, 2nd at 17, finished at 18. *Much more even roast. *Lots of chaff.

    Packed them all up, and Ill let them sit for a few days now.

    Hopefully, shortly Ill be moving on to a Stir Crazy/Convection Oven combo. *Ive already got the convection top, and I have a Stir Crazy base in transit from the US. *Once I do a voltage conversion on the base, Ill be good to go. *Im hoping for more uniformity in the roasts from this setup. *Ill let you all know when it arrives, and how well it works out.

    Regards,
    Phil

    Great post Phil!

    Any chance of getting some tasting notes on those coffees? I am particularly keen on the Moka on the Malabar, I missed out on both :(

    I am now experimenting with the Harar. I roasted it to the 2nd crack yesterday. I get the sense that this bean could go a little darker. What do you think?

    Cheers,
    Avi

    Thanks Avi,

    Im going to put some detailed tasting impressions up in a few days once the beans have settled a bit more.

    But, I couldnt resist trying some of the Yemen last night. Its certanly a different coffee! Very chocolatey, and a hint of liquorice as well. To be honest, Im not sure Im impressed at the moment, but Ill give it a few more days.

    I also tried a 50/50 Harrar/Kenya blend. This one is really nice as a Cappa - very smooth and a pure coffee taste. Interestingly, these Kenyan beans are the most gassy Ive ever had. They keep literally blowing the top off the container that theyre in! And the flow from the portafilter looks like the flow from a Coke machine. Its really thick and frothy.

    I havent tried the Malabar as yet, but Ill let you know.

    As for roast levels, I tend to find that a rolling 2nd crack seems to be the best for espresso, so thats where I usually start experimenting.

    Regards,
    Phil

    Hi Phil,

    Thanks for the notes, I am looking forward to your detailed tasting notes.

    A 50:50 Harar/Kenya blend...wow! Thatd be one powerful blend! I love the Kenyans, but my main problem is - how do I blend this for straight espresso? I havent really had any success so far using the Kenya in an espresso blend. I generally use it with a plunger or Vac Pot, wheres its absolutely stunning.

    I agree on the rolling 2nd crack for espresso. Anything lighter seems to taste kinda "green". The only exception I have experienced is the Yirgacheffe, which seems to like a roast just before 2nd Crack.

    The 2nd Crack has been a thorn in my side since my early days of roasting. I could never seem to be sure of when it actually starts. Alan Frew tells me that 2nd Crack officially starts when it begins "rolling". So I guess that that puts that issue to rest :)

    The only challenge now is trying to predict when it starts so that I can stop the roast, and cool the coffee just when it hits 2nd crack. Alas...nothing is easy.

    Cheers,
    Avi
