Context

Second cup, first pass at Guatemala.

Beans came from the freezer before grinding. Purified water again.

While loading grounds into the preheated cone, I paused to smell. Heat from the cone lifted everything upward and made it feel more immediate, almost amplified. 🦄 said it smelled darker than cup one this morning. That felt true.

Also notable: all 308 g of preheat water went into the Switch in one movement, leaving the kettle empty. One body of water, fully accounted for.

Brew Notes

Held grind at 1.8.3 to keep first-expression baseline clean.

RTT with three spritzes.

Dose came in a little low (15.7 g vs 16 g target). Brew water landed at 255.6 g against a 256 g target.

Bloom expansion was moderate. Surface tension held without aggressive bubbling. Drawdown stayed steady.

Spent bed again showed the same pattern as cup one: faint high-water mark around the perimeter, then a slide toward center with a slight wall cling before the interior cleared.

No obvious channel holes. More of a wash-to-center shape than a flat immersion bed.

Observe

Dry aroma from the heated cone read darker: cocoa, faint toasted sugar, less fruit-forward than earlier coffee.

Wet aroma was rounder and a little earthy.

First sip came in with softer acidity and a darker entry. Mid-palate leaned cocoa-first with muted fruit. Sweetness sat in brown-sugar territory rather than bright fruit. Bitterness stayed gentle and integrated. Body felt medium, slightly fuller than cup one. Finish was short cocoa.

There was an accidental 0.8 g inclusion of Mocha Java (roughly 5%). Small, but possibly enough to deepen the chocolate edge.

Grounds still showed small white flecks, which I have seen before in some Parable coffees and some Ruby coffees. Not universal. Possible chaff fragments or lighter inner material exposed by fracture.

Reflect

The darker smell profile matched both the visual read and the cup structure.

The repeated slide-to-center bed pattern across two different coffees now feels less bean-specific and more like something systematic in drawdown flow.

The 0.3 g dose miss likely mattered little by itself, but it belongs in the record.

A living “Current Recipe” note, preheat protocol, pour consolidation, grind baseline, agitation philosophy, feels like the right next move for separating technique drift from bean expression.

i. grind

Second cup started with a small calibration puzzle: measured 15.9 g because there was about 0.1 g lingering in the Timemore grinder from earlier.

Ground at 1.8.3 again, which has been the stable home setting lately.

Used the RDT aerosolizer again (same as cup one). There was still a little clumping at the bottom, but noticeably less stubborn than the first cup of the day.

When the catchment came off, the aroma rose deeper and more complex than expected. The moment felt like a seance for language: attentive, waiting, seeing what words might precipitate out.

ii. brew

Used purified water and the new brown filters.

Tried a slight process update for preheat: poured the full 300 ml into the Hario Switch, then let that drain into the Patagonia mug.

Previous preheat runs used only 200 ml to match gooseneck capacity; this time skipped the gooseneck for preheat entirely.

Also wiped down the Maestri House timer with a microfiber cloth. It had become stained. Care in cleaning.

iii. observe

The grinder still has not had a deep clean.

It raised the cast-iron question: once something is seasoned, what should be left alone versus scrubbed back to neutral?

Soap-and-water cleaning on the Switch, mug, and small grounds cups seems to preserve cup clarity. Grinder maintenance is less obvious and worth proper research.

iv. action items

• Look up grinder-cleaning cadence and whether retained oils can ever be beneficial.
• Add a possible research-entry type to the beans log for standalone notes and mini essays.
• Add terminology entries (for example, RDT) so recurring brew terms have a canonical home.

Final grounds check: output landed at 15.8 g, so the retained amount was slightly overestimated.

v. tasing

bitter first and second sips.
it’s a corkscrew shaped taste.
