Fermentation showdown, AeroPress craft, and Colombian extremes

Hoffmann Fermentation Project
James Hoffmann just gave enthusiasts the fermentation blind taste test.
The Fermentation Project ships four samples from the same producer and harvest—one control, three isolated fermentation methods (wild, lactic, yeast)—so you can brew identical recipes and hear how processing alone reshapes the cup [Quelle: Craft 42 Roasters]. Craft 42 is among the selected roasters worldwide offering the $60 CAD kit. A global live tasting runs October 3, with local Kelowna cuppings featuring brewing demos.
This is controlled experimentation for people who actually brew.
Thailand AeroPress champion's water recipe
Ponlasit Peepanich won the 2026 Thailand AeroPress Championship by obsessing over mineral water.
His naturally processed Omkoi coffee from Chiang Mai rode a custom water profile—TONIK and TANAT drops for bright citrus, JAMM and LYLAC for sweetness—tuned through blind tastings at his shop's daily practice sessions [Quelle: APAX LAB]. He's now representing Thailand at the World AeroPress Championship in Mexico, carrying proof that extraction engineering beats heroic technique.
Water design is the frontier most brewers still ignore.
Diego Bermudez's fermentation extremes
Colombian master Diego Bermudez just released a coffee that's part clean, part chaos.
Total Eclipse blends a washed Geisha against his signature Anti-Maceration fermentation—the funky end producing passion fruit and peach preserves intensity that once seemed artificial [Quelle: Black & White Coffee Roasters]. The cleaner lot anchors the fermentation-forward wildness while maintaining craft chocolate and natural wine edges. It's fermentation theory you can taste side by side.
Bermudez's two-lot tactic turns processing into argument.

Ponlasit Peepanich won the 2026 Thailand AeroPress Championship using a naturally processed coffee from Omkoi, Chiang Mai, prepared with carefully designed water profiles. His winning approach centered on revealing the coffee's inherent character rather than forcing it into something new—he used a brewing water combining TONIK, TANAT, and KONFLUX drops to highlight bright citrus acidity and fruit clarity, paired with a dilution water of JAMM and LYLAC drops to enhance sweetness and balance. Peepanich's preparation involved extensive blind tastings to understand how mineral profiles influence extraction and flavor, supported by community practice sessions at his coffee shop where brewers gathered daily. He will now represent Thailand at the World AeroPress Championship in Mexico.

Diego Bermudez, a renowned Colombian producer known for innovative fermentation techniques, has released a specialty coffee blend that showcases his mastery of processing methods. The "Total Eclipse" is a blend of two lots on opposite ends of the fermentation spectrum: a clean washed Geisha and a Caturra processed with Bermudez's signature "Anti-Maceration" technique that produces intensely funky fermentation-forward flavors. Bermudez's use of primary and secondary fermentation has historically produced nuanced, complex flavor profiles so intense they were once suspected of being artificial. The blend combines tropical fruit notes like passion fruit with cooked stone fruit and peach preserves, with the cleaner lot balancing the fermentation-forward intensity while maintaining what the roaster describes as craft chocolate and natural wine characteristics.
