You may find that all the extra attention to details as water temperature or precise pouring pace may be unnecessary for you, at least at first. I was intimidated too, especially for the equipment, but then I started brewing using a normal kitchen scale and a stove kettle without thermometer, only relying on the boiling point, and I have to say surely I have less control over the final result but still I enjoyed very very good cups of coffee So I’d suggest you to just give it a shot doing your best but without unnecessarily hassle and improve your technique a bit at time

You can also brew and then forget about it for 15 minutes only to realise when it’s too late and the whole thing is cold-warm

Actually I did it one time, but every response I got was in English even if the user was a Japanese speaker. So I started worrying that the translation was incorrect, even if it was specified that I wasn’t a Japanese speaker. I wonder if maybe, especially in the Fediverse context, Japanese users might be pretty used to English and Latin alphabet in general so that it may be easier to them if I just write using the language I actually know in order to avoid mistakes

It seems like you did some tests, how do you think the frequency of the pouring influence the final taste?

That’s a curious finding, where was the shop located if I may ask?
