Full-volume experimentation
Eighteen of nineteen available recipes used no stated bypass: all stated brewing water was used during extraction rather than added afterward.
In 2019, the three podium recipes used 30–35 g of coffee. When the championship returned in 2021, all three used the new 18 g maximum. The recipes still differed in water, grinding, filtration, temperature, pressing, and service.
We analyzed 46 available podium recipes from 2009–2025 to see how recipe design changed.
Recipes moved from full-volume brewing, to high-dose concentrates, to 18 g concentrates with bypass.
Eighteen of nineteen available recipes from 2009–2015 had no stated bypass. Most recipes in both later periods used it.
Competitors differed in water, particle preparation, filtration, temperature, agitation, pressing, and service.
Within each edition, every competitor received the same coffee. Their podium recipes were still different.
We used past podium recipes to propose a first recipe for testing under the new rules.
Official podium recipes with usable source records.
2009–2025, excluding the absent 2020 edition.
All editions used one common coffee; seven retain a complete official identity.
11 of 15 used major differences in preparation, filtration, temperature, pressing, or service.
46 available recipes from 16 comparable editions. The archive also includes two unavailable podium positions and the contextual 2008 winner, bringing the indexed total to 49 records.
Every chart links back to the raw workbook and official recipe archive.
In 2019, the three podium recipes used 30, 30, and 35 g of coffee. When the championship returned in 2021 after the missing 2020 edition, all three podium recipes used exactly 18 g.
Every dot is one available podium recipe. Horizontal displacement separates the three places within a year.
Rule note: The 18 g maximum for 2021–2025 is based on confirmed competition-format information and strong support from the podium recipe sequence. Frozen annual rule documents for those years were not recovered.

The recipes fall into three broad periods. These are our working periods, not official championship eras.
Eighteen of nineteen available recipes used no stated bypass: all stated brewing water was used during extraction rather than added afterward.
Ten of twelve available recipes used a high-dose concentrate-and-bypass structure.
Dose narrowed while water allocation, preparation, filtration, pressing, and service stayed diverse.
Source: Official World AeroPress Championship recipe archive; Brew Supply analysis. n = 46 available recipes.
Concentrate recipes use less water during extraction, then add water before or after pressing. This chart shows that split. It does not measure extraction yield.
n = 35 recipes with exact, internally consistent water amounts. The diagonal marks no stated bypass; points above it contain additional water before or after pressing. Total stated water is not the same as final beverage mass. Ranged or internally inconsistent records are not forced into this chart.

Select a recipe—or click any eligible point—to see all 13 compatible variables together. Strong lines show up to three selected recipes, faint lines trace the active period cohort, and hovering reveals the competitor, value, percentile, and usable n.
Choose a recipe and comparison period. All 13 compatible variables stay visible together; the faint connected field and every percentile update with the comparison period, while selected recipes outside it remain visible at a clamped 0–100 position.
Higher means a larger numeric value, not better coffee. The shaded area covers the middle 50% of eligible recipes; the line at 50 marks the median. Eligible n still varies by variable inside the all available podium recipes cohort.
Profile summary: Jan Ahrend’s 2025 recipe: coffee dose sits near the middle of recorded values; brew water is lower than most recorded values; press start sits near the middle of recorded values; press duration was not stated.
Grind settings are not included in the field-wide profile because click values are not comparable across grinder models and calibration systems. Grind position not available for field-wide comparison.

The horizontal axis shows the recipe value. The vertical axis shows the championship year, with newer years at the top. The shaded band covers the middle half of usable values, and the line marks the median. Small offsets separate recipes from the same year.
Dry coffee used in the brewer.
Dose spans several rule periods. The tight 18 g cluster belongs to 2021–2025, while earlier recipes ranged much more widely.

Water documented as contacting the coffee during brewing.
This separates short concentrate extractions from recipes that put most or all stated water through the coffee bed.
Source: Official World AeroPress Championship recipe archive; Brew Supply analysis. n = 41 usable records in the selected period.
Brew water contacting the coffee divided by dose, displayed as coffee:brew water.
Lower values indicate a more concentrated extraction stage. Bypass is excluded, and this is not measured extraction yield.

Water added outside the main extraction phase, before or after pressing.
Zero is shown only when the source supports a no-bypass recipe. Missing or internally inconsistent amounts stay out of the chart.

Bypass water as a percentage of reconciled total stated water.
This makes recipes with different overall water amounts easier to compare. It still describes water allocation, not extraction yield.

Reconciled brew water plus bypass water.
Total stated water is an input total. Coffee retains water, so it is not the same as final beverage mass.
Source: Official World AeroPress Championship recipe archive; Brew Supply analysis. n = 35 usable records in the selected period.
Reconciled total stated water divided by dose, displayed as coffee:total water.
This includes bypass and describes recipe inputs. It does not represent final beverage mass or measured extraction yield.

The stated beverage mass after pressing, dilution and finishing.
Coverage is sparse and competition minimums changed. This is shown for service context, not as a performance signal.
Source: Official World AeroPress Championship recipe archive; Brew Supply analysis. n = 8 usable records in the selected period.
A documented brew-water temperature where the source supports one comparable value.
This number describes brew water, not the complete temperature strategy. Differently tempered bypass, staged additions and post-brew cooling remain separate recipe details.

Number of documented filter layers, regardless of material.
Layer count is comparable as a count, but paper, metal, cloth, modified filters and filter thickness are not equivalent.

Elapsed brew time when pressing began.
Press start helps locate the transition from steeping to pressing. It does not include press duration or describe pressure and flow rate.
Source: Official World AeroPress Championship recipe archive; Brew Supply analysis. n = 30 usable records in the selected period.
Documented time spent pressing the brewer.
Duration is useful, but it does not capture force, flow rate, output target, bed resistance or whether the brewer stopped before the hiss.
Source: Official World AeroPress Championship recipe archive; Brew Supply analysis. n = 33 usable records in the selected period.
Elapsed recipe time through the documented end of pressing or brewing.
Archive wording is inconsistent about whether cooling, dilution or service steps are included, so the source notes remain important.

The competition has always given every competitor the same championship coffee within an edition. Seven editions retain enough official detail to identify the common coffee precisely.

The raw layer preserves the original wording, units, grinder description, coffee description, and ambiguity.
The official archive wording is stored separately from Brew Supply’s transcription and comparison fields. We record comparable values only when the source supports them. Approximate values, ranges, and conflicting instructions remain visible.
A recipe may be included in the dose chart but left out of a single-value temperature chart. Each figure shows the number of recipes it can support.
The horizontal axis shows the usable value. The vertical axis shows the championship year. The shaded band covers the 25th to 75th percentile, and the line marks the median. Period filters recalculate the chart for the selected years.
Each recipe has one broad structural family. Separate notes preserve unusual features such as multiple grinds, mixed temperatures, modified filters, staged additions, external vessels, multiple presses and post-brew conditioning.
The dataset contains podium recipes only. Historical rule documents and exact coffee identities are incomplete. Older recipes are often described in less detail, and grinder settings cannot be compared as universal particle sizes.
The official 2026 rules require at least 150 g of brewed coffee. We do not apply that number to earlier editions without a surviving source. For example, the 2016 archive explicitly describes 200 g as that year’s competition minimum.
