Selected by Let's Make It Fund × BambuLabSelected by the Let's Make It Fund — Bringing Brew Supply to life with BambuLabIn 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. Yet recipe design did not converge. Variation remained in water, grinding, filtration, temperature, pressing, and service.
We analyzed 46 available podium recipes from 2009–2025 to see how recipe design changed.
Podium recipes moved from full-volume brewing, to high-dose concentrates, to lower-dose concentrates with more process variation.
No-bypass recipes dominated 2009–2015. Concentrate-and-bypass recipes dominated both later periods.
Competitors continued to differ in water, particle preparation, filtration, temperature, agitation, pressing, and service.
Every competitor used the same coffee within each edition, but podium recipes still differed widely.
The starter recipe is a practical first test, not a proven championship formula.
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.

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.

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 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.
