HAVE YOU EVER HAD A BLACK DIAMOND COFFEE?

Some coffees make us question what we thought we knew. Black Diamond is one of them. This is our second year offering this remarkable lot from Las Lajas, and somehow it's even sweeter, cleaner, and juicier than the version that captivated us last year. Chosen by Jes, our Director of Roasting, at origin in Costa Rica, this coffee showcases the innovative Black Diamond process, where sugars slowly crystallize during drying to create exceptional clarity and sweetness. Roasted light to preserve its vibrant character, expect notes of candied grapefruit peel, pomegranate, and honey.

12 oz bags are available for a limited time.

Built Through Experimentation

Some of the most interesting coffees begin with a problem. When an earthquake disrupted water and power during harvest, Oscar and Francisca Chacón didn't abandon their process; they started asking better questions. That curiosity helped shape what would become Las Lajas' Black Diamond Natural Process. Only the ripest cherries, measuring above 22° Brix, are selected before spending 22-30 days drying slowly under the Costa Rican sun. After drying, the coffee rests for more than 60 days, allowing moisture to stabilize and sweetness to deepen before milling. Every stage moves deliberately, giving the coffee time to become itself. It's a process built on patience, observation, and the belief that remarkable coffee isn't found by standing still, but by never stopping learning.

Our Approach to this coffee

We roasted this coffee with a light touch to preserve its bright grapefruit character while developing enough sweetness for juicy pomegranate notes and a rounded honey finish. We found its best expression on a pour over with a slightly coarser grind than usual, which brings remarkable clarity and balance to the cup.

On drip, expect more acidity and decadent cacao notes, with a smoother mouthfeel. Give this coffee 7–21 days of rest after roasting; this one gets fruitier and fruitier with more rest.

V60 Recipe:

Grind: Med-coarse
Coffee In: 24g
Bloom for 30 seconds: 40g of water
Total Brew Water: 360g
Final Brew Time 2:10-2:40
Tips from Jes: I did a 40g bloom (typically I do 70g), agitated the bloom, and then no more agitation. This kept my brew time to about 2 minutes and 30 seconds, which was the perfect extraction.

How fresh is your coffee?

Our coffee is roasted fresh to order and ships within 24 hours to ensure peak flavor. For optimal taste, we recommend brewing between 4 and 21 days after the roast date—this allows the coffee to degas and fully develop. After that window, it will still taste great for several weeks (or more), especially if stored in a cool, airtight container.
