How to Roast Colombia HEIGHT PREMIUM ESMERALDA Green Beans

When you buy a single-origin green coffee labeled "premium" but find the beans vary wildly in size, you're facing a real roasting challenge—especially if it's meant to outclass a well-known Supremo-grade bean. That’s exactly what happened in September 2011 when a batch of Colombia HEIGHT PREMIUM ESMERALDA arrived at the roastery. Despite its high position in the lineup, the inconsistent bean size made even the roast curve harder to control.

To get the best results from this premium Colombian lot, roasters stopped the roast right at the start of the second crack. That choice—along with subsequent brew adjustments—made all the difference in how the coffee tasted over the first few days after roasting.

What Is Colombia HEIGHT PREMIUM ESMERALDA?

HEIGHT PREMIUM ESMERALDA is a top-tier Colombian green coffee, positioned above the standard Supremo grade. Though it comes from Colombia—a country known for its high-altitude Arabica grown along the Andes—it presented unique challenges due to inconsistent bean sizes. That variation directly impacted how it could be roasted, especially if aiming for a profile that highlights its inherent fruitiness over roast-driven bitterness.

Why Roast to the Start of Second Crack?

This particular roast was stopped at the beginning of the second crack. That’s a critical moment in the roast process: the first crack signals the bean structure loosening, and the second crack means further breakdown of cellular material and increased oil migration. By ending the roast just as the second crack begins, the roaster aimed to preserve more origin character—like bright acidity and fruity notes—while avoiding excessive roast flavors that can mask those qualities. This choice is typical when handling high-quality beans where clarity and varietal traits are prioritized over heavy body or smokiness.

First Impressions and Brewing Results

When brewed the first day using an 80°C water temperature and a cloth filter (likely a flannel drip or similar pour-over method), the coffee was harsh. The water may have been slightly too hot, leading to an overwhelming impression of burnt or astringent bitterness. There was little lift in aroma, and the initial sips were dominated by bitterness, with acidity emerging only later. Over time, though, the cup opened up into a more balanced profile: clear fruit acidity with subtle sweetness, and the bitterness faded. By the second day, the flavors had significantly improved. Roasters noted that deeper roasts might not suit this bean, as they could obscure its delicate characteristics.

Flavor Development Over Time

Many specialty coffees show noticeable changes between the first and third day post-roast. This lot was no exception. The initial day’s cup was dominated by roast-induced bitterness, likely exacerbated by slightly too-hot water and fresh roast CO₂ interference. By day two, the coffee settled into a more expressive profile: bright fruit acidity came forward, balanced by mild sweetness and a smoother mouthfeel. The recommendation to let it rest underscores a common reality in specialty coffee: flavor often peaks a day or two after roasting. The roast level—stopped at the start of second crack—allowed enough sweetness and origin character to develop properly with time.

Frequently Asked Questions

What is Colombia HEIGHT PREMIUM ESMERALDA?

It’s a high-grade Colombian green coffee bean, ranked above the common Supremo grade. It originates from Colombia’s mountainous regions, known for producing high-quality Arabica, but in this case, the beans varied in size, complicating the roast.

Why was the roast stopped at the start of the second crack?

Stopping the roast at the onset of the second crack helps preserve the bean’s intrinsic acidity and fruit notes while limiting excessive roast flavors. This approach is ideal for showcasing origin characteristics in high-quality beans like HEIGHT PREMIUM ESMERALDA.

What brewing method was used for this coffee?

The coffee was brewed using an 80°C water temperature with a flannel (cloth) filter, likely a pour-over method similar to a Fukamushi or traditional drip. The relatively low brew temperature helped reduce bitterness in later brews.

Why did the coffee taste better on the second day?

Like many freshly roasted coffees, this batch needed time to degas and for flavors to balance. Day-one tasting was affected by bitterness and possible over-extraction due to heat, while day-two cups revealed clearer fruit acidity, sweetness, and smoother overall balance.

Should this coffee be dark roasted?

No. According to the roaster’s note, this particular Colombian bean does not suit a deep roast. Dark roasting can mask its delicate fruit acidity and sweetness, reducing its complexity and origin expression.

What water temperature worked better for this coffee?

Lower water temperatures, such as 80°C, produced better results. The initial higher temperature led to excessive bitterness and limited the perception of the coffee’s more nuanced fruit and sweet characteristics.
