先日、近所のスーパーに寄ってびっくり、実はここでは知り合いの喫茶店のセルフブランドのドリップバッグ が置いてあったりして、 やるなーと思っていたのです。何しろ、コーヒーの品揃えに関しては、福岡市近辺のスーパーと比べてもダントツすごい、 種類も…

このケニアはCOEクラスなので、自分としては珍しくディベロプメントは90秒か100秒くらいで止めた。 普段はありえない相当の浅煎りだったのですが、 以前何度か、浅煎りの豆を脱酸素剤で処理していて、１週間ぐらいならまだしも、ある一定の 期間を過ぎると、…

ひょっとすると、やっとのこさ、なんとかコーヒーの良しあしがある程度判別できるところまで 嗅覚が戻ってきているかもしれません。 実は去年から、飲みやすいアイスコーヒーを作るのはテーマにしていたのですが、アイスで 豆の良さが伝わるような焙煎という…

たまたま、1年近く前に焙煎したケニアのドリップバッグが見つかったので、試してみました。 焙煎合宿で使った分の残りを去年の10月の終わりごろに焙煎したものの一部でした。 開封してみると、本当に、ドライがスペシャリティしている！！作成直後より香りが…

Established a record since the dawn of this blog.

I found out the reason why the outcome of roasting varies and get worse especially during the hot season. The high humidity in Kyushu have a big influence on roasting much more than I expected. And when the humidity becomes a big issue thi…

takes couple of hours just to brew

The weather here is very moist around this season. It requires much calories to roast and It makes roasting on fuji r-103 a bit harder because my machine only have six burners.

For the magnetic swiches are 30 years old and out of production. It is taking such a long time to inquire the specifications for alternate. I decided to dismantle the magnetic switches and found out the reason why they trip so frequently. …

a new format or matrix I made a new format to record roasting process supporting long range roast up to 40 minutes or more. May be I should try roasting without preheating.

nice fashionable counter One of my friend insist me I should go push my bean to be introduced to a coffee shop in mid of fukuoka pref. Although they serve coffee with beans of a famous speciality coffee roaster. I found a new branch of the…

can't find time to make a solid control panel Now, I don't need to peep in the monitor just to check the temps.

Newly cropped beans are coming one after another. I would like to get them for stock but I am so short of resource. Only l can get a kg or two per a crop. May be I should go for a cloud funding.

I re-examined the current batches to find out that I forgot and omit one batch which I had to put the beans on the roaster twice. I did not intend to do this but the fire went off at the early stage of one before last roasting. Out of tota…

If it were bussiness, this makes less than 40％ yield and is not enough to produce any profit but creating loss because the beans loose weight and the yield shrink down. Plus you need to select the beans to tune up the taste and their appe…

I found a way to adjust the front drum gap to minimum, to the point where you can't go any closer. It was possible to close it up much closer than cold position when it is hot enough to roast. Today I had to rotate the drum by my own hand …

I have been waiting for some components; the designated glue for the back panel heater is going to come next week and so on. And my sence of taste and smell have not yet recovered fully I suppose this is the reason why I cannot enjoy coffe…

I was looking through some old batches which I thought were useless, I found that the roasting had been going very smooth and almost perfect untill the drum stopped. So, I decided to restore one before last settings and try similar profile…

Now the cylinder is empty and the propane is gone. As I was checking the machine, I found that the nuts and poles on the back panel were so easy to remove that it gives me a good way to attach the external back panel heater. Today, I also …

Something I have written in past 30 minutes have all gone. Internet is very slow here via nuro. When the beans being heated up they release certain amount of steam and when they reach to the boiling point the pressure in the drum drastical…

It turned out that the influence of excess heat storage at the front panel can be avoided by slanting the machine to lean back by some degrees. Now all the moters working fine, I do not have to worry about the drum motor that used to stop …

I was about to throw away like trash one of the previous batches though, something struck my mind that I tried it over a drip bag and turned out it was one of the best batches with that roasting degree; at least when it is served by that c…

My old fuji have only 5 blades on exhaust/cooling fan which means that the wind could be more or less 10% weaker than now standard 6 blade and 25-30% less than the 8 bladed special model. To compensate this I set the inverter frequency at …

Its tuff enough to rotate at 132hz or 2.5x speed If I adjusted the drum gap right, the drum might not have stopped during the previous batch. But it is not good to work on a machine caring about or fearing that it could stop at anytime, I …

Some survery on antibody made in USA suggest that approx. 50 to 80 times of known number of infected person may have already caught ncov. I wonder what it will be like in this country.

There left a green leaf on the branch of a coffee tree. Saigo no ichiyou I found its lost by today. literally and litterary, gone with the wind

Since mid February. I had been felling something wrong in my sence of taste and smell, I could not enjoy the flavor that comes out of black & brown beans and also my physical condition was not so well that I stopped roasting and went on re…

It stopped again whilest I was going to start roasting the mandelin G1. In fact i had to assist the motor by grabing the belt several times.Guess, I must have poured in the raw beans much gentely. It proved that the density of the mandehli…

Inverter driven exhaust/cooling fan In the first place, I didnt want to change the motor this early because I have been so short of resource that I wanted to go on with what I had. But the incident happed one day when I was checking the ga…

I ve bn working on the roasting stuff for quite a while and found out that the ideal roasting I have been looking for largely depends on the quality of the raw bean. It has to be old traditional seeds , typica or like and refined then trea…
