We've been watching the H1 varietal change things on the farms we work with in Guatemala. Here's why it matters — and what it actually tastes like in your cup.
What is the H1 varietal?
H1 is a hybrid varietal created through a collaboration between the World Coffee Research (WCR) and regional coffee institutes. It’s a cross between the high-quality Sarchimor (a hybrid of Timor and Villa Sarchi) and Rume Sudan, a wild Ethiopian variety known for its unique flavours. The goal of this hybrid was to combine resilience with exceptional cup quality, addressing the growing challenges posed by climate change and coffee diseases like leaf rust, that can be detrimental in Guatemala.
Why is H1 so significant?
Guatemala is renowned for its diverse coffee-growing regions, ranging from the high-altitude farms of Huehuetenango to the volcanic soils of Antigua. However, this diversity also exposes farmers to various challenges, including leaf rust (“roya”), erratic weather patterns, and increasing costs of production. H1 presents a solution to some of these issues.
One of H1’s standout characteristics is its resistance to leaf rust or "roya", a fungal disease that has devastated coffee farms across Central America. By planting H1, farmers can reduce the risk of losing crops to this pervasive threat.
H1 thrives at a range of altitudes and climates, making it a versatile choice for varied landscapes and diverse microclimates. Its resilience in diverse growing conditions ensures that more farmers can adopt it without compromising on yield or quality.
The hybrid’s higher yield potential and reduced need for fungicides make it an environmentally friendly choice.
Unlike many disease-resistant varietals that compromise on flavour, H1 maintains a very high cup quality. In the cup it's expressive — think stone fruit, jasmine, clean sweetness. It rewards a good filter brew.
The future of H1
As the coffee industry evolves, H1 represents a promising path forward for Central American farmers facing environmental and economic pressures. Organisations like Anacafé (Guatemala’s national coffee association) and global research initiatives are working to support the increased use of H1.
In Guatemala, where coffee is more than just a crop—it’s a legacy—the H1 varietal offers hope for a thriving future, blending tradition with innovation.
