Variety Selection Strategy: Choosing the Right Coffee for Your Farm

Why Variety Matters

Coffee variety is the genetic foundation of everything that follows. It determines potential cup quality, yield per hectare, disease resistance, and market positioning. Choosing the wrong variety for your conditions is a mistake you live with for 15-20 years.

On our farms in Caicedonia, Valle del Cauca, we grow multiple varieties. Each selection is deliberate, balancing agronomic performance with cup potential. I have learned this through trial and error -- some expensive, some rewarding.

The Varieties We Grow

Castillo

The workhorse. Developed by CENICAFE (Colombia's coffee research institute), Castillo was bred for resistance to coffee leaf rust (roya) -- the disease that devastated Colombian production in 2008-2012.

• Cup profile -- clean, balanced, chocolatey with mild acidity. Typically scores 80-84 SCA.
• Yield -- high, consistent producers
• Disease resistance -- strong resistance to roya, moderate to CBD
• Best for -- reliable production, conventional and estate-grade specialty

Castillo is our volume backbone. It pays the bills. Not the most exciting in the cup, but when you need consistent cash flow from a farm, Castillo is the variety that lets you take risks elsewhere.

Caturra

The classic. A natural mutation of Bourbon discovered in Brazil, Caturra has been grown in Colombia for decades.

• Cup profile -- bright acidity, citrus notes, medium body. Can score 83-87 SCA in ideal conditions.
• Yield -- moderate, slightly lower than Castillo
• Disease resistance -- susceptible to roya -- requires active fungicide management
• Best for -- plots with excellent conditions where you can invest in disease management

Caturra produces exceptional cups but demands more attention and carries more risk. On some of our best plots, Caturra consistently outscores Castillo by three or four points on the cupping table. That difference justifies the extra management cost -- but only if you stay on top of roya.

Geisha

The star. Originally from Ethiopia, Geisha became famous after Hacienda La Esmeralda in Panama scored record-breaking SCA numbers in competition.

• Cup profile -- floral (jasmine, bergamot), tea-like body, complex tropical fruit acidity. Scores routinely reach 86-90+ SCA.
• Yield -- low, significantly below Castillo and Caturra
• Disease resistance -- moderate to low
• Best for -- premium microlot programs, competition coffee, high-altitude plots

We grow Geisha on select high-altitude plots. The economics only work at specialty prices -- but when they work, they work exceptionally well. I will never forget the first Geisha lot we cupped that broke 88. The jasmine aroma was unmistakable, and it proved that our terroir could compete with the best Geisha-producing farms in the world.

Bourbon

The heritage variety. One of the oldest cultivated Arabica varieties, prized for sweetness and body.

• Cup profile -- caramel sweetness, full body, soft acidity. Scores 83-88 SCA.
• Yield -- low to moderate
• Disease resistance -- susceptible to roya and CBD
• Best for -- heritage lots, markets that value traditional Colombian profiles

I have a personal soft spot for Bourbon. There is something about the caramel sweetness and body that represents what Colombian coffee should taste like. We process some of our Bourbon lots as black honey, and the combination of Bourbon's natural sweetness with that process creates a cup that buyers remember.

How We Decide

Variety selection follows a decision matrix:

1. Altitude and microclimate -- Geisha needs higher elevation (above 1,600m). Castillo performs well across all our elevations.

2. Soil conditions -- some varieties are more sensitive to low pH or aluminum toxicity, conditions we monitor through soil testing and fertilization planning.

3. Disease pressure -- plots with high roya history get rust-resistant varieties. Period.

4. Market demand -- buyer requests influence new plantings. Our export clients increasingly request specific varieties.

5. Cash flow -- low-yield premium varieties only go on plots where the farm can absorb three years without income during establishment.

The Diversification Principle

We do not plant a single variety across all our farms. Genetic diversification is a risk management strategy. If a new disease strain overcomes Castillo's resistance, our Caturra and Geisha plots are unaffected, and vice versa.

The ideal farm portfolio balances volume varieties (Castillo) for cash flow with premium varieties (Geisha, Bourbon) for differentiation and higher margins. It is the same logic as any investment portfolio -- you do not put everything in one asset, no matter how good it looks today.
