George Jinyang Peng won the 2025 World Brewers Cup in Jakarta by the narrowest of margins with a Panama Gesha and a meticulous dual-temperature routine. Pre-heat the brewer thoroughly — Peng says it 'makes a massive impact on flavor.' Over 15g of medium-ground coffee, pour in three phases: 30g, then 90g of hot (~96°C) water, then a final 90g of cooler (~80°C) water through a Melodrip to tame turbulence and flow. The whole brew finishes in about 1:45 for an aromatic, high-clarity cup.
