Dialing-In Coffee Notes

··
Cooking

I never really liked coffee, it was always a bit too harsh and the effort involved in adding a myriad syrups to lessen the blow never really seemed worth it. However, in late 2024 I was visited by a close online friend who lives in Aotearoa. Being adjacent to Australia, there is a bit of a culture of coffee snobbery. The morning after her arrival tried to have a cup from Mr Coffee machine’s pot and almost spit it out. We went out and she bought single-origin grounds (no actual grinder was at available) and using my digital electric kettle instead of the Mr. Coffee heating element, she brewed the first pot of coffee I actually cared enough to finish unadulterated. That experience, along with the fact we will likely see each other again and I do not wish to offend her most delicate sensibilities (🩵), has caused me to actually take a crack at coffee.

Equipment

It’s pour-over coffee stuff, but for posterity:

  • Hario V60 Switch Immersion Dripper (Size 03)
  • Hario V60 Coffee Server (Size 03/1000mL)
  • TIMEMORE Chestnut C2 Manual Coffee Grinder.
  • The digital electric kettle I got like 3 years ago at Costco.

Coffee

On a lark, I went to Whole Foods and bought two bags of store-brand single origin beans (Colombia and Costa Rica). Both are light roasts as they are being immersed in water, which will cook the grounds a bit, so dark roasts would likely burn.

2025-01-04WF Costa Rica Light801:15Immersed until the largest of the bubbles popped (≤5 seconds) then drainedInitial test; I don’t have anything to compare it to.
2025-01-07WF Costa Rica Light801:15[My actual-chef partner made this one] Filled drip feeder entirely, let sit for ~2 seconds, then dropped (repeated around 3 times for 650mL)Initial test; I feel as though I could actually taste the notes on the package, which I assumed was just flavour text.
2025-01-08WF Costa Rica Light801:15I attempt to emulate my partners steps as they were outlined above, however I feel I dropped the coffee much longer than after 2 seconds.Bitter, burnt. I messed up and I know it. I think if I were as deft a hand as my partner I would have had a repeat of yesterday but alas.
2025-01-14WF Colombia Light801:?My chef-partner eyeball’d the ratio, seemed to be maybe 30g beans but I didn’t see how much water was added.He has the magic touch, however. It was very sweet, I thought sugar was added but no, it was unadulterated.
2025-01-15WF Colombia Light801:14.89Under partial supervision of NZ friend (very late in Aotearoa as I did it so she may not have paid the best attention). Water was filled to bloom, agitated with the back side of a plastic spoon, and then drained. As it drained the water was refilled without stopping the drip until ~350mL was in the pot.Not as burnt as the 8th, but not good. Tastes like the very best of coffee-machine-coffee, but nowhere near as magnificent as what I otherwise get to experience.
2025-05-14WF Colombia Light881:16Made by visiting NZ friend. Left initially to bloom for 30 seconds and then dropped, topped off continuously until all water was added (3 times). Checking the date, I will note that both coffees are a month or two past their best-by date.It was fine. I made the mistake of immediately adding creamer as I forgot my procedure specifics and I got distracted by something and forgot to drink it while hot.
2025-05-15WF Costa Rica Light921:20Another by NZ friend. Left to sit for 60 seconds before dropping due to more being brewed, continuously refilled after.A bit bitter, but not burnt. This has me questioning if the bitterness is more a trait of the coffee than the maker. While this establishes a hierarchy of me < NZ friend < my partner in terms of talent, I still lack enough data to emulate my betters.
