Well, finally got around to completing my first roast today on the Cormorant this morning. Roasted a Kenyan from the Ndundu farm which I tried to keep on the lighter end. Definitely a learning curve - Found it a little difficult to keep a track of everything, so decided to just use Artisan to mainly look at what was happening with the temperatures. Don’t have all the stats at hand but just now focussing on getting to grips with the machine. Dropped very soon after first crack (20 seconds) and visually happy with the results. Tried a quick cup and the acidity is nicely preserved and has very nice sweetness. Body at the moment feels a little thin but perhaps it needs a bit more resting. To be honest I probably should have dropped at 45 seconds but we will see how it develops over the week. I used 500 grams and came out with a weight loss ratio of 12.5%.

Beverast A little more time would help I agree.

Cormorant 600 Electric

DavecUK Yeah cheers for reinforcing my suspicions. It’s definitely lacking that creamy body I am used to so will try again tomorrow morning.

Beverast

Did 1 more cheeky roast before calling it a day for today. This time Cafe Granja La Esperanza’s washed red bourbon. Dropped 1 minute 30 seconds after 1st crack. Apologies not the best quality photo. Will cup tomorrow morning and attempt the Kenyan again.

Beverast are you simply espresso?

Beverast

Cuprajake Yeah that’s me bud haha 😀

Would love to post more but finding the time is difficult - between working full time and finishing off the 4th year of my degree, I just find it difficult to get the motivation. I will upload again just need to be in the right frame of mind so to speak.

Cuprajake

Mind = blown

I thought you had died when you stopped up loading 😂

Glad that you’re on here, you should share more of your thoughts on your setup, I reckon @DavecUK could do a sticky for the repair mod you did to your machine too if there isn’t one already

Beverast

Cuprajake I really appreciate the message you sent me on Youtube asking me if I was okay. Didn’t mean to scare you 🤣

To be honest my repair mod was not the best video…my main aim was to let people know there was a fix and that ECM are still a company you can trust.

Beverast

A crude setup, but it works. Ventialtion works great. Majority of the smoke gets vented outside my window…the only smoke that remains is a when you open the roasting chamber to drop the beans. My open window and extractor fan get rid of any excess smoke. To be honest I get more of a roasting smell with the Kaffelogic. Gotta keep the missus happy 🤣

Beverast I own a cormorant too. Great roaster. If you can get an external cooling fan it makes life much easier between batches. The built in fan is fine, but if you plan on roasting more than one batch another cooler is beneficial.

Beverast

StevenG91 Thanks for the advice mate. Which external fan would you recommend?

StevenG91

Beverast ill try and get the link for you.

Done a test roast this morning - Colombian Diego Samuel Bermudez. Could never get the roast “right” on this bean on the Kaffelogic for some reason. Trying to get strawberry and dark chocolate notes. The beans appear a bit darker than my photo suggets - I have rubbish lighting inside my home which is why I prefer to take shots outside. I think I pushed this one just a little too far, probably should have dropped 20 seconds earlier - getting a bit more roastiness than I usually like. Cupping this definitely getting the strawberry notes, so glad that remains. Think this will be more suited to espresso rather than pourover, so will let this rest for a few days and try it in the Puristika.

Cuprajake

Could you link to where you got the greens. Been looking for a high strawberry coffee for a while now.

Beverast

Cuprajake Will do mate. Got this from Falcon Micro last year, but it’s long out of stock unfortunately.

Beverast

Final roast for today, washed Ethiopian Nano Challa Lot #40. Got this from Falcon Micro recently but it’s out of stock now - was £60 for 5kg which I thought was fair. Have had some good success with this one on the Kaffelogic. Did a quick cupping of this and yes I am happy how this one has turned out - good acidity, sweet and flavourful, but does need a good rest imo. Have posted my log from Artisan - If anyone has advice on things that look out of the ordinary please comment. Dropped this 1 minute 20 seconds into first crack. Also, have done photos of the roast outside and inside my home for comparisons.

Edit: It’s actually not sold out and is available here: https://www.falcon-micro.com/shop/uk/ethiopia-nano-challa-washed-heirloom/

DavecUK

Beverast Can you output the graph in C?

Beverast

DavecUK Done. This was a 500gram batch.

Beverast

I know it’s not long post roast for the Ethiopian Nano Challa but thought I would try a cup this morning - I have been recovering from a cold over the last few days, and this morning my taste buds feel back to normal. 18grams brewed in the Aeropress for 2 minutes. Delicate, almost tea-like in it’s structure, fruity and floral, medium acidity balanced by returning sweetness, body thickens a wee bit once cooled, just light and flavourful. Will get even better in my opinion after a few more days resting. Will also do some comparisons with a batch I roasted on the Kafflogic which also impressed me.

In other news I will be getting another Ethiopian from Falcon Micro soon (order this one last week). I ended up getting the last bag:

Farm – Arbegona
Location – Arbegona Highlands, Sidamo
Varietal – Mixed Heirloom Varietals
Process – Natural
Altitude – 2200masl

Cup Score – 89

Cup profile : Vanilla, strawberry, bergamot, stone fruit, floral and syrupy.

Beverast I would increase your charge temp and gas. Your FC onset is quite late on.

Beverast

Well almost a potential disaster…the machine tripped my mains at nearly the beginning of first crack. Almost instantly I dropped the beans in the tray and put them outside. Now trying to figure out how this happened…

Edit: Have checked out the IR tubes and one of them is not working. Will dismantle and do a thorough check once the machine is fully cooled and will more than likely have to replace the tube.

Beverast

I have emailed Johan as taking out the faulty tube was extremely difficult. All the other tubes are “loosish” and fit snug but this one took some serious elbow grease to get out. It was not like this when I first put it in. Now I cannot get the spare tube into this section as it is way too tight and I do not want to force it in or anything like that. Also checked one of the other tubes and it looks like some wire is exposed - I have asked him if it will cause any potential problems.
