Abstract

This intense Gesha comes to us from our new friend Diego Bermudez. This now iconic coffee goes through a double fermentation thermal shock process, which yields intense sweetness reminiscent of peach and mango, perfectly balancing the florals from the Gesha variety.

Origin

Colombia

Colombia uniquely offers a diverse array of coffee varieties and processing methods. Known for innovation and resilience, Colombia's coffee history dates back to the early 19th century, with smallholder farmers being key contributors. Despite challenges like weather and conflict, Colombia consistently produces high-quality specialty coffee. For over a decade years, we've partnered with both large and small-scale producers from all five main growing zones, fostering close relationships and friendships.

Elevation

1950 MASL

Elevation influences coffee cultivation, impacting flavor and quality. Higher elevations offer cooler temperatures, slowing the growth of coffee cherries, allowing more time for complex sugar and flavor development. This results in coffee with brighter acidity and a nuanced flavor profile. Additionally, cooler conditions at high altitudes reduce pests and diseases, making these coffees highly prized for their superior quality and distinct taste.

Variety

Gesha

Known for it's delicate, tea-like texture and pungent florals, Gesha is the most sought after variety in the world. After winning the Best of Panama this variety has skyrocketed in fame, going on to dominate the sphere of high-end specialty coffee.

Harvest

Colombia

Colombia has a unique harvest schedule, thanks to the varied topography and proximity to the equator. Between those two variables, Colombia harvests nearly year round across the five main coffee growing regions. Each region has fairly reliable harvest times that conveniently stagger, providing fresh crop coffee all year round.

Process

Thermal-Shock

This coffee undergoes a mixed oxidation four day fermentation, followed by depulping and channel washing. The numerous steps of this fermentation include sixty-hour fermentation in a tank, along with an additional long fermentation within a sealed tank under pressure and inoculates. The parchment coffee is then dried for approximately sixteen days on patios. The processing impact in the final cup is noticeable, with flavor indicating fruit-forward signs of fermentation within the overall cup profile.

Drying

Raised-Bed Dried

Raised-beds are scaffold like structures that elevate perforated trays that hold coffee parchment or cherries. The holes in the structure allow for airflow on a near 360 degree level, ensuring that the coffee dries evenly when proper bed turning is practices. Some even go as far as covering the beds with a partial block from the sun, which extends drying and ensures the cell structure of the coffee goes largely undamaged from the UV.

Roasting

Diedrich CR-35

Prior to production, each roast goes through a rigorous dial-in process, where we fine-tune our temperature curves. We roast to tight tolerances, with no more than 1° deviation from target temperatures, ensuring quality and consistency in each batch.

Referring to medium as moderate is an intentional choice to highlight the roasting process, which is also referred to as development. Coffees within the moderate range exhibit notes in line with terroir, with a hint of sugar-browning. These characteristics are backed by a medium to high perceived acidity with a balanced tactile and sweetness, and they adapt easily from espresso to filter preparation.

Inventory

331 LBS

When producing and roasting high-end specialty coffee, there are times that such a small lot of a high caliber coffee is produced, that we choose to pack it within boxes and ship it via airfreight. We tend to sell these ultra-small lots for pre-order, so that we can control sales and roasting of these coffees. Typically, these are Geshas, auction lots, or something else high-end and exclusive.

Extraction

Filter, Espresso

Our Education Team, guided by a commitment to quality, uses a blend of sensory skills and technology to brew the best coffee in our cafes and brew guides. We strive for vibrant and mouthwatering acidity, complex and approachable flavor, persistent and clear sweetness, and structured and pleasant mouthfeel, ensuring you're getting the best coffee experience.

In twenty twenty-four, Diego Bermudez needs no introduction. He has long been in our periphery, as we've tasted coffees produced by him since the days of his 'red plum' process, and since, Diego has skyrocketed into true coffee rockstar status. Both himself and his tight-knit team have produced competition level...
