Roasting Notes on Colombia HEIGHT PREMIUM ESMERALDA Green Emerald Coffee

Ever roasted a high-end Colombian single origin only to find the cup lacks clarity or balance? In this 2011 roast log, a specialty roaster faced exactly that problem with Colombia HEIGHT PREMIUM ESMERALDA—a lot labeled above SUPREMO grade—yet hampered by inconsistent bean size, leading to surprising results.

To get the best from this lot, the roast was stopped at the start of the second crack, brewed the next day at 80°C on a cloth filter—and improved notably overnight.

What Is Colombia HEIGHT PREMIUM ESMERALDA?

HEIGHT PREMIUM ESMERALDA is a premium-grade Colombian green coffee, positioned above the standard SUPREMO grade. It originates from Colombia’s renowned coffee-growing regions, particularly those within the Andes mountain range where volcanic soils and elevation between 800–2300 meters create ideal growing conditions. Despite its premium classification, this lot featured beans of irregular size, complicating the roasting process.

Why Roast to Second Crack?

This particular roast was intentionally stopped at the beginning of the second crack. While many Colombian coffees shine at a lighter or city-plus roast level to highlight acidity and fruit, this batch’s uneven bean size posed challenges. Roasting through the start of second crack helped achieve a more balanced development, though it moved the profile away from bright floral or tea-like notes often associated with light roasts.

The roaster noted that deeper roasting was not ideal for this coffee, as it risked suppressing the inherent fruit character and emphasizing only roast-driven bitterness.

Brewing Method & Flavor Development Over Time

The coffee was brewed the following day using a 80°C water temperature and a cloth filter . Initial tasting revealed issues: the water may have been slightly too hot, leading to an overwhelming burnt or overly bitter cup with little aromatic lift. However, after 24 hours, the cup transformed significantly.

By the second day, tasters noted a much more pleasant cup: prominent fruit acidity appeared first, followed by a balancing sweetness and a fading bitterness. While the dry and wet aromas were not especially vibrant initially, the cup eventually showcased a clear fruit-forward acidity with mild sweetness, marking a notable improvement over the first brew.

This evolution underscores how some coffees, particularly those with complex roast profiles or uneven bean lots, benefit from rest time to allow gases to dissipate and flavor compounds to harmonize.

Mistakes & What to Avoid

Key takeaways from this roast log include:

• Irregular bean size can complicate heat transfer during roasting, requiring careful monitoring, especially near first and second crack.
• Stopping the roast at the onset of second crack can be appropriate for certain premium lots to balance body and acidity—but may mute some brighter floral notes.
• Overly hot brew water (above ideal pour-over range) can exaggerate bitterness and mask delicate aromatics.
• Coffee flavor, especially from complex roasts, often improves markedly after 24 hours of rest.
• This coffee is not well suited to dark roasting, which suppresses its inherent fruitiness.

Frequently Asked Questions

What is Colombia HEIGHT PREMIUM ESMERALDA coffee?

It is a high-grade Colombian single origin coffee, positioned above the typical SUPREMO classification. It comes from Colombia’s mountainous regions with elevations between 800–2300 meters, though this specific lot had inconsistent bean sizes that impacted roast consistency.

At what roast level was the Colombia HEIGHT PREMIUM ESMERALDA stopped?

The roast was stopped at the beginning of the second crack. This decision aimed to balance the roast profile considering the challenges posed by irregular bean sizes.

What brew method was used and what temperature?

The coffee was brewed using a cloth filter with 80°C water. Brewing the next day at this temperature produced a significantly better cup than the first attempt, which was brewed at a slightly higher temperature and resulted in excessive bitterness.

How did the flavor change from day one to day two?

On day one, the cup was dominated by harsh bitterness and lacked aromatic complexity due to likely overheating. By day two, the coffee developed pronounced fruit acidity, followed by sweetness, with bitterness gradually fading—an improvement in balance and clarity.

Is deep roasting suitable for this coffee?

No, the roast log specifically notes that this Colombian coffee does not perform well with dark or heavy roasting, as it can suppress its natural fruit character and emphasize only roast-derived bitterness.
