AeroPress Championship Grind Settings

A grinder setting becomes interpretable only after the hardware is named. Model and burr geometry affect how coffee fractures. The adjustment mechanism controls how far the burrs move per step. Zero can mean the first point where the handle no longer falls, burr touch, or another manufacturer-defined reference. Wear, assembly, alignment, and retained coffee can add more variation. Calling every setting '24 clicks' removes the information needed to reproduce it.

Comandante's current FAQ defines C40 zero operationally and tells users to dial in for their own grinder, coffee, and preference. It does not give one universal AeroPress setting. That is the right mental model for competition recipes: a documented click can be precise inside its system while remaining non-transferable outside it.

Brew Supply's practical rule is to copy coordinates only when the model, burr system, adjustment mechanism, and zero definition match. Otherwise copy the recipe's purpose—faster or slower extraction, press resistance, contact schedule, and cup target—and find a local setting through controlled brews.

Six settings were stated directly on the standard C40 mechanism and six were mechanically converted from Red Clix. The analysis uses the documented relationship of Red Clix clicks divided by 2. A 52-click Red Clix record therefore becomes 26 standard-equivalent clicks. The conversion preserves the adjustment mechanism; it does not claim that 26 clicks equals a measured micron value.

The twelve settings were 20, 22, 24, 24, 24, 26, 26, 27, 28, 32.5, 33.5, 37.5. Repeated values are retained because they are separate recipe records, not duplicates to delete. Jan Ahrend's second-place setting and Dharun Vyas's third-place converted setting sit inside this group, but two podium examples do not turn the median or any individual value into a winning optimum.

The range is wide because grind works with the rest of the recipe. Dose, brew-water amount, temperature, agitation, contact time, filter resistance, bypass, pressing, particle preparation, and coffee all changed across records. A coarse setting in a highly agitated concentrate cannot be interpreted as the same choice as that setting in a fuller-volume, gentler brew.

The 2025 source uses Hammerhead as a Comandante C40 grinder or burr-system label. It is not a Pietro comparator. A shared C40 family name still does not authorize putting Hammerhead clicks on the standard C40 axis because the burr and click-system context differs.

The exact Hammerhead settings were 22, 27, 28, 30, 52. Their wider numeric span does not prove that Hammerhead recipes were ground finer, coarser, or more aggressively than strict-C40 recipes. The two axes do not share a calibrated physical unit, so comparing the raw endpoints would be false precision.

One additional Hammerhead-associated recipe described a split grind and carried an estimated setting. It remains outside the five exact records. A blended or sequential grind creates a particle distribution that one averaged click cannot faithfully represent, particularly when fines or chaff are deliberately removed afterward.

The separate records are one estimated split grind, one Trailmaster/Tigershark setting, 3 unresolved Comandante settings, and one model-limited C40 record whose click context does not meet the strict comparator rule. These are not missing from the report; they are intentionally unpooled.

Némo Pop's first-place recipe used a Trailmaster X25 with Tigershark burrs at 31 device-specific clicks. That is valuable named-recipe information, but it belongs to that hardware. Placing 31 on the strict-C40 scale would erase the winning recipe's actual grinder system rather than make it easier to reproduce.

This boundary also prevents a misleading field average. Adding device-specific coordinates together can produce a mathematically valid number with no physical meaning. The honest answer to 'What was the average championship setting?' is that no single cross-system average should be published.

Those numeric records include different Comandante contexts and older commercial or hand grinders. Other recipes supply qualitative descriptions, ranges, conflicting values, or no setting. The historical report therefore leaves grinder settings out of its field-wide numeric profile instead of treating a Ditting number, an EK43 position, a Macap dial, and a C40 click as equivalent.

The historical archive answers chronological podium questions; the audited 2025 sample answers same-final comparator questions. They overlap on the three 2025 podium recipes but remain separate datasets with different denominators. This guide uses the historical archive only to show the documentation and compatibility boundary, not to expand the 2025 finalist denominator.

A future archive could compare trends inside one well-identified grinder system, but it would still need stable model, burr, zero, and conversion rules. More numbers alone do not solve incompatibility.

Start by recording the source grinder, burr or axle, click system, zero definition, and any sifting, chaff removal, or split-grind step. Then lock coffee, dose, brew-water amount, temperature, filter, agitation, steep time, bypass, press start, press duration, endpoint, final mass, and tasting temperature. If several of those change, the grind comparison cannot teach you which variable moved the cup.

Choose a sensible AeroPress baseline on your own grinder rather than guessing a cross-brand conversion. Brew it twice. Record press resistance, total time, visible channeling or clogging, output, and taste after the cups reach a comparable temperature. If the brew is repeatable, move one small step finer or coarser and repeat. Change direction based on the complete result, not a simplistic rule that every sour cup must be finer or every bitter cup coarser.

Use AeroDial to keep the source coordinate, local coordinate, and neighboring recipe variables visible. The goal is not to discover the setting that a champion used in isolation. It is to find the local setting that makes the intended recipe reproducible with your grinder, coffee, water, and service target.
