Lempira

Honduras’s widely planted rust-resistant variety, whose resistance broke in 2017. A lesson in how pathogens adapt.

Lempira is a Catimor-family variety released by IHCAFE and planted very widely across Honduras from the 1990s.

What happened in 2017

A new race of coffee leaf rust emerged that Lempira could not resist. Because it had been planted so widely and so uniformly, the outbreak spread fast and did severe damage.

That is the textbook risk of monoculture in a resistant variety: the pathogen only has to solve one lock.

The response

Honduras has pushed diversification — Parainema, Obatã, IH90 and others — rather than replacing one dominant variety with another.

The cup

Clean and moderate, typical of the Catimor family. Fine at altitude, unremarkable below it.

The wider lesson

Resistance is temporary. Every resistant variety deployed at scale is on a clock, which is why breeding programmes never finish.

Brewing it

Filter or espresso at medium roast.

What you need to make it

The equipment this actually requires — not a shopping list, the shortest route to doing it properly.

  • The reference pour-over Manual brewers

    Hario V60 02 Ceramic

    60° cone · spiral ribs · 1–4 cups

    The most transparent cup you can brew for twenty euros, and the least forgiving. Ceramic holds heat where plastic does not — and the open bottom means your pour, not the dripper, decides the coffee.

    Best for: Someone who wants to taste what a single-origin coffee is actually doing.

    8.2/10

    ≈ $25 / £20 / 22 €

  • Best filter grinder Grinders

    Fellow Ode Brew Grinder Gen 2

    64 mm flat burr · filter only · single dose

    64 mm flat burrs, near-zero retention and a footprint the size of a mug, built for filter and honest about not doing espresso. For pour-over it is the clearest grind you can buy at this price.

    Best for: V60, Chemex, AeroPress and batch brewing, where clarity is the whole point.

    8.7/10

    ≈ $345 / £275 / 300 €

  • Best pour control Kettles

    Fellow Stagg EKG Pro

    0.9 L · ±1 °C hold · counterbalanced gooseneck

    The best-pouring kettle sold, and the hold function matters more than the thermometer. Expensive for boiling water — but if you brew pour-over daily, it is the accessory that most improves the cup.

    Best for: Daily pour-over, where flow rate is the variable you are trying to control.
