    PNG Gouno Highlands

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Has anyone tried roasting this one yet? I picked up a bag because I really enjoy the Wahgi AA (my favourite SO *:) ) and was keen to compare the two. I tried my first batch this morning after resting it for 7 days and I must admit that it just didnt do it for me. Very sharp and quite bitter both with and without milk. My wife arrived at the same conclusion. I cant help thinking I went wrong somewhere with the roasting and havent done it justice. Either that or its just an acquired taste. I roasted to approximately CS9, perhaps slightly deeper. I wasnt able to stretch the time between FC and SC to more than about 4>4.5 minutes on this one. Pulled it immediately at SC (approx. 16.5 minute mark).

    I might have to blend it with something else in the cupboard to smooth it out a bit.

    Gday Buschy...

    As it happens, these beans come from a completely different region of PNG to the Wahgi beans so a difference is to be expected Id reckon...

    As with the Wahgi though, youve got to be quite careful not to roast these beans too quickly or too deeply; theyre quite a soft bean even though theyre grown at a pretty decent altitude. Beautiful part of PNG where the Gouno comes from..

    Try roasting them so that Rolling First Crack arrives at between 12:30 and 13:00 minutes but be sure to reduce the heat once FC starts to get a move on; and then aim for a gradient that gets you to about CS8-9 about 4:30 to 5:00 minutes after the end of RFC (not the end of FC) and then immediately cool. Dont let the beans hit the start of Second Crack at all as they really seem to accelerate very quickly into a very dark colour and take on an ashy, burnt flavour in the cup.

    I really these beans with this roast profile and then anywhere from 3 days onwards after bagging. They are a pretty lively bean with good acidity but I have never though of them as bitter though. See if you can run a small batch to the profile above and then see what you think. I hope theyre a bit better for you... :)

    Re: PNG Gouno Highlands

    Hi,
    I have done 2 roasts of this bean. It has turned out to be one of the best coffees we have tasted. It has a rich milo-malt extract-caramel character that is so tasty that the beans are used up quickly.

    I dont qualify as a coffee snob as I havent been into coffee for long, I dont have an espresso machine or a decent grinder, just an electric blade grinder and a plunger. So the roasting I describe below may not be quite right for espresso.

    I havent done many roasts and I dont have any temperature readout. I use a bread machine and a heat gun.

    I reached FC at 6 minutes and I backed off the heat immediately to have a long roast and to reach only the mid point between FC and SC. I managed to stretch it out to 12 minutes to the end of roast and by the colour it seemed to be mid way between FC and SC. I didnt think the roast went well at all.

    The day after the roast the coffee was tasting really nice and it improved each day. I tried to do the second roast just the same and although slightly different times the coffee was really tasty again. I dont want to change the times for the next roast either.

    Chris.

    Thanks Mal,
    Had a look on the map. Yes, Gouno Highlands further SE. I havent been to that part of PNG. My wife has seen parts of that area via helicopter, mmm...maybe one day I will be as lucky... *::). It sounds like I have the ramping up to RFC about right but not reducing the heat enough after that point. I do raise the gun once I enter RFC but Im a bit cautious now as Ive raised it slightly too much a couple of times and have stalled the roast, or temp. *has gone down instead of up *:(. Will try to stretch out the time after FC but pull the beans around the time you suggested. Cheers. *

    Happy to hear youre enjoying the beans! *:). Im far from an expert on roasting but FC at 6 minutes with a breadmaker/ heat gun combo sounds very soon! *:-? However... given that the end result tastes good perhaps youre onto something! *;)

    Re: PNG Gouno Highlands

    No worries Buschy....

    Dont forget to let us know how it works out mate. ;)

    @Chris:
    Excellent stuff Chris. You know what we all say around here... Its what is in the cup that counts so if your brews are igniting your palate this way, then thats great. Stopping before the onset of Second Crack is the big thing with these beans so I wouldnt change that at all.

    Once you get a handle on the processes of roasting though, dont be afraid to experiment a bit as its only by doing this you will discover many other facets to roasting the bean and the huge range of flavours that it is possible to extract. Its a great hobby....

    Happy roasting guys :) 8-)

    Re: PNG Gouno Highlands

    Just roasted my first few batches of this on the popper, and boy was Mal right. It is so sensitive to timing around second crack. I had a play with timings - 20 seconds shy of second crack (or there-abouts), on second crack, and 20 seconds after second crack........the results are astoundingly different.

    I havent cupped these yet, but the post-second crack roast was a CS11 and a bean chew gave a charcoal taste. The pre-second crack roast was a CS9 with my mouth much happier after a bean chewing session.

    Im very interested to see how these taste! :P

    Excellent mate.... 8-)

    Mind you, most beans taken to CS11 would probably not taste their best ;)

    Look forward to reading your impressions in a few days....

    Cheers :)

    Re: PNG Gouno Highlands

    Ok, so I got a little excited and cupped it this morning - I think it definitely needs a few more days. Now, I am still a wee amateur at this and dont have a well developed palate at all, however, I did get a malty character that Chris spoke of. Ill keep you posted over the next couple of days to see how it develops

    On another note, I split a double of this into 3 shot glasses (20ml each) to investigate how the flavour changes over the course of an espresso. Was very interesting! Obviously there were significant colour changes in each, with the darkest crema in the first 20ml. Flavour wise, I found that pretty much every bit of flavour came in the first 20ml (was also quite bitter). The next two 20mls were both fairly neutral on the palate with no bite (still tasted good though).
    Has anyone ever done this before??

    Cheers,
    Ben

    Re: PNG Gouno Highlands

    Ok - this is a strange bean. Never done PNG before. I was totally amazed at the expansion of the bean mass. I started out 2.5 inches below the rim of the BM basket and ended up slightly overflowing!!! I also noted that it ran away quickly to just starting the SC....next time I will pull it earlier.

    I like the smell though and I am keen to taste it....FC at 13.5 mins and pulled at 18 mins as she just started the SC.

    I would like to do a Mal next time so I will roast less and make it more controllable - this roast was 850 grams.

    Cheers

    PS. Just finished off my Yirg so that will be hard to compete with... ;)

    Re: PNG Gouno Highlands

    This is too strong for my liking - certainly cuts through the milk. It is getting better with age and the pours are quite nice, but I think I have taken this bean past its best with my roast...will try again with a slightly smaller batch.

    Cheers

    Yes mate,

    This seems to be quite typical of a lot of PNG varieties, even from different regions of PNG. Dont know why this should be, bean density perhaps? Anyway, my experience has been similar to yours and after First Crack(FC) has finished, I keep a very close watch on them and pull them just before the onset of Second Crack(SC). Even at this stage of completion, the beans are still quite dark and probably close to CS10.... More reminiscent of a roast taken beyond SC... :-?

    Re: PNG Gouno Highlands

    Thanks Mal - Im backing up from a 1kg of Yirg so its so really fair to the PNG...this Yirg was the best batch I have done of that bean and its just so lovely.

    Cheers

    Re: PNG Gouno Highlands

    This one is so much better in the cup...as I pulled them and did the fan thing they just gave a few sc snaps (VERY close to end of rolling SC)....they taste amazing just a day post post....

    Here is the profile.

    Cheers

    Re: PNG Gouno Highlands

    You might want to try slowing it down a little between 1st and 2nd... and extra minute there could imporve them even more.

    I find that most bean profiles peak when that 1st-2nd crack line is flatter.

    Re: PNG Gouno Highlands

    I will try mate - the problem is that I can only get the ramp down to a climb rate of 4-5 degrees per min with my set up...I think where I hit the first crack was actually about 15 seconds before where I entered it so that would be a bees under 4 mins between the 2. *I have set up a mate with Corretto and his set up allows a steady climb of only 2-3c/min, but I just cant go that low without risking a stall...so I might be on the scrounge for a smaller bread maker because thats what he has...unless its not worth it for that extra 30c - 1 min?

    Cheers

    Edit: I should back of the temp with this bean before it goes exothermic - that would give me about 6 mins between first and second...it really gets away this one.

    Yeah, thats what the graph looks like... bean momentum running its own race after 1st.

    How about adding some cold air? It will give the same end result. Maybe blow a fan into the bean mass after 1st crack and leave your heatgun at its low setting?!?

    Anything that gives you some flex and choices during profiling is a good thing. ...and as always, cup em to determine which you prefer.

    Re: PNG Gouno Highlands

    Thanks Andy. I will do as above but back these off at 170 degrees say to get the line a little flatter so when it starts the FC I can back off more easily and it shouldnt run away. I use a fan. I will do another one and report back.

    Cheers

    Re: PNG Gouno Highlands

    Here is mark 2 - not as linear but 4.1 mins between the FC and pulled just before SC, so while I would like to smooth it out a bit (....I wonder if my 2 group cutting in mid roast might have caused a new drops!) it should be very different to previous iterations - especially the 9 mins FC.

    Any feedback welcome.

    Cheers

    Re: PNG Gouno Highlands

    actually they were pulled at 13.68 but resizing and mucking around with the charts make the scale look a bit out.....

    Re: PNG Gouno Highlands

    I just cannot stretch these little babies past about 4 mins to dropping them (at 208 odd they are just before SC so I cannot leave them any longer and risk going to the SC)....might be time to think about a smaller more upright bread maker.

    Cheers

    Re: PNG Gouno Highlands


    Nah, no need to change the bread maker if the roasted results are good. My numbers were just an observation of what I would do given the same profile... which might not be correct!

    4 minutes is fine, just dont shorten it else you might find they will end-up sour as the insides might not be roasted to the same level as the outside.

    PS: can you please remove hte FAT bmp image? Its way too big for a webpage. If you "save as JPG or PNG" it will be a fraction of the size.

    Re: PNG Gouno Highlands

    I just did another - this time 12 mins FC and 16 mins pulled - actually 4 mins and a handful of second between the 2....I am attempting jpeg this time.

    Cheers

    PS....this is the sort of profile I prefer - nice slow ramp and then 4 mins

    pps. I tried doing the JPEG with the last one and I failed...bit computer challenged

    Re: PNG Gouno Highlands

    On paper , this looks like a good profile.
    How long is your turnaround from dropping in the green beans?
    What are the results like that you are getting off this profile?
    Are you finding much of a difference in the taste between this profile and your prvious one with a shorter time between first and second?
    Cheers,
    Carlos.

    Re: PNG Gouno Highlands

    Oomph - I have made some changes to my set up and now see 5.5 - 6 mins between FC and dropping the beans just on just before or just after the SC first snaps depending on the bean or how I like to do the bean...and the results are better again than what I was achieving before.

    Cheers
