At two thousand meters, water can simmer around ninety-three degrees Celsius, nudging extraction toward sourness unless variables shift. Try a slightly finer grind, longer bloom, reduced agitation, and smaller pulses. Taste after each adjustment, noting mouthfeel changes, delicate acids, and surprising florals that appear when patience replaces brute heat and pressure.
We packed compact lever brewers and a stalwart stovetop pot across windswept passes, finding that preheating pistons, insulating cups, and slow, steady pressure curves preserved crema better than forceful thrusts. Fuel efficiency mattered, as did wind screens, but most decisive was grind consistency carried in a sealed tin against shifting humidity.
