Cold-Brewed Coffee/水出しコーヒー

Last night, I made cold-brewed coffee, using the very fine grind. My cold-brewing method is quite similar to my ice-brewing method. 昨晩は、極細挽きを使って水出しコーヒーを作りました。私の水出しコーヒーの作り方は氷出しコーヒーの作り方によく似ています。 1.

Another Fuji Royal R-440/もう一つのフジローヤルR-440

This week, I got another R-440 (right) at action. The R-440 is available in two types, the regular type and the type capable of making an espresso grind.

At first, I decided on the desired […]

Lukewarm-Brewing Coffee/コーヒーのぬるま湯抽出

I wanted to know what it would be like to brew coffee with lukewarm water rather than hot or cold water. I searched for an answer on the Internet, but in vain.

Ice-Brewed Coffee/氷出しコーヒー

I have already talked about ice-brewing coffee here in my blog. I wanted to have affogato made with iced-brewed coffee, so I made another experiment. 氷出しコーヒーについては既にこのブログのここで述べました。氷出しコーヒーで作ったアフォガートを食べたかったので、また実験をしてみました。 You will need 40 g finely ground coffee to make 250-300 ml cold-brewed coffee. Ice-brewing calls for a fine grind. Making ice-brewed coffee does not mean that you have to have it […]

Cleaning the Fuji Royal Coffee Mill R-440/フジローヤルのコーヒーミルR-440のクリーニング

Today, I disassembled my R-440 to clean it thoroughly. I used a brand-new toothbrush and my vacuum cleaner for this work, among others. 今日は、R-440を分解して、徹底的に掃除しました。そのために新品の歯ブラシと掃除機などを使いました。 Well, not spanking clean but clean enough to grind coffee beans without hesitation.ピカピカとは言えませんが、ためらうことなくコーヒー豆を挽けるまでにきれいになりました。 This washer was a mystery to me. After searching on the Internet, I realized that it was apparently […]
