Finally got round to my 1st roast on the cormorant at the weekend.

 

600g Brazil Dattera Sweet.

 

Roaster warmed up to 180 @ 37mbar and beans dropped.

 

1st crack @ 10.24 rolling @ 10.57

 

Gas dropped to 10mbar

 

Beans dropped @ 13.05

 

Roast didn’t run very smoothly, a lot more to think about than the gene.

 

Beans a lot darker than I was aiming for.

Hi Iroko

 

As you probably know it always takes time to get to know a new roaster. Are you planning on using digital thermocouples at all? I find the analogue probe to be somewhat slow to react - though one can roast with it as Johan has demonstrated.

 

I tend to warm my Cormorant up slowly at 20 mbar fan on about 6.5v when the temp gets up to about 200c usually about 12 mins or so I turn the burner off and let the roaster cool down to about 170c then bring it back up.

 

I do a part bean soak for about a minute, burner on about 15 mbar damper closed, air at 5.3v, then after a minute burner to 37 mbar, damper open and air to 6.3v. Once I hit around 130c I will start slowly bringing down the burner - I aim to hit drying a little over 5 mins on a larger load and around 4.30 on a 400g batch. Once past drying I increase air a little to 6.8v and am bringing down the burner - aiming for around 2.5 mbar by 170c. I tend to get FC on my machine between 190 and 195c. I close the damper around 185c and am usually at around 2 mbar by FC. I will also increase air to about 7.2v just before first crack. I then aim for between 20-23 % development time depending on bean.

 

I should note that these temps are using a digital probe which reacts much faster than the analog and makes it far easier to see where your roast is going.

 

I've found this basic profile works as a good starting point.

 

Good luck with your new adventure!

 

Best Phil

Hi Phil

 

Yes It's going to take some time to get used to the roaster, not as straight forward as the Gene. I've got thermocouples but not sure when I'll start using them, and not really sure

what other equipment I need to use them, I'm not too good with computers.

 

Thanks for all the above info, on my next roast I'll try to think ahead of what I'm doing. :confused:

 

Cheers.

I was not happy with last weeks roast, so roast No. 2 was done at the weekend.

 

500g of El Salvador Finca San Ernesto.

 

I used the above profile from Beeroclock

 

I hit 1st crack @ 9.36 with temp @ 185

 

I forgot to stop timer when roast dropped, but was about 12 mins

 

500g in 456.6 out

 

Much happier with this roast.

This was the same bean that was roasted with Johan which I really enjoyed, still drinking from this bean and still tastes great as It has got older.

I'll be trying this roast at the w/end, hopefully It will be as good.

 

When I roasted this bean on the Gene I remember not being as good, but It was quite a while ago.

@eddie57 Brazil Daterra was the penta pack from Bell Barista a good few years ago. I had some that I had forgotten about, I used these for my first roast so i wouldn't be to

fussed If I messed the roast up.

The penultimate roast before (dare I say it) ********* Christmas!

First in was 1kg of Monsooned Malabar. I have previously done this as a 900gm lot, but decided to try a kilo. It went OK.

1st pops @ 10.15sec and rolling @10.56sec

Dumped @ 13.27secs

14.7% loss.

Next in was the last of a natural Brazilian 16/18 from Andre Sanchez. At about £4.50something a kilo, this coffee has been very pleasing.

1st pops at 11.20secs and rolling @1140sec

Dumped at 13.40secs.

A nice even roast, loss 15.6%

Followed by a washed Ethiopian Yirga cheffe Gr2 from ECX and a private import.

1st pops 11.50sec and rolling 12.11secs. The heat was turned off once rolling and roast ended at 14.35.

Loss 15.3%

Next was another Ethiopian, becoming a favourite, Guji Highland Estate. A small 250ha farm along with some outliers produce the lovely coffee.

1st pops 10.53secs, rolling 11.24secs

Ended ar 13.46secs

Loss 14.1%

Last was another favourite from Kenya. A high scoring 90, AB sized washed at the Ngugi Ini washing station.

1st pops 10.10secs and quickly into a vigorous rolling @10.20secs.

Heat turned off t about 11min and roast dumped at 12.34secs.

Loss 12.8%

Including the warm up (28mins) to beans loaded, and cool down and clean up etc, less than 2 hours.

Espresso Blend 500g 021218.jpg

 

So I've been buying quite a few greens from small batch recently - especially as they're now offering 5kg bags on some of their speciality coffee. They've recently added a pre blended espresso offering - something I would never have previously considered, but have bought a 10kg bag and am pleasantly surprised at how well it has roasted and produces a really nice milk based espresso cup.

This was the first roast following a long drawn out annual service on the Amazon. I roast on roughly 14 day intervals. I started doing the service the first day following the last roast. If it was there, it caused hassle! But now I have done one, next years should be a walk in the park.
