Caturra Coffee Beans

Caturra coffee is a single-gene variant of Bourbon, discovered in Brazil in the 1950s. Caturra coffee beans are most suitable for cultivation from 700 meters at low altitude to 1750 meters at high altitude. The higher the altitude, the better the flavor, with refreshing fruit acidity and a light sweetness.

Research on Serving Temperature and Flavor

In 2017, the journal "Food Chemistry" published a research paper titled "Influence of serving temperature on flavor perception and release of Bourbon Caturra coffee."

As usual, let's get straight to the key points!

Research Methods

Two methods were used to evaluate the coffee.

1. Cupping to evaluate coffee flavor

The sensory analysis evaluation team consisted of 8 trained members who needed to evaluate the coffee flavor at 6 different temperatures (31°C, 37°C, 44°C, 50°C, 56°C, 62°C).

The sensory vocabulary used for evaluation included: "overall flavor intensity," basic tastes "bitter," "sweet," "sour," as well as flavor notes "tobacco," "roasted," "nutty," "chocolate."

2. Dynamic headspace gas chromatography-mass spectrometry to analyze volatile aromatic components in coffee

The specific principles of this method can be found in the book "Coffee Flavor Chemistry."

Key Findings

1. Sweetness at 44°C

When cupped at 44°C, Caturra coffee is sweetest. Combined with the analysis results in the paper, at this temperature, the coffee contains high levels of pyrazine, and the corresponding flavor descriptions for pyrazine are: sweet, corn-like, nutty, etc.

2. Higher temperatures increase bitterness

When the coffee temperature is 50°C or higher, the content of alkylpyrazines increases, making the coffee more bitter with roasted flavors, and the overall flavor intensity is also higher.

3. Lower temperatures reveal non-roasted flavors

When the serving temperature is below 44°C, Caturra coffee will exhibit more "non-roasted" type coffee flavors, such as "sour," "sweet," and "tobacco."

Colombia Huila Finca La Cabaña Washed Caturra

In recent years, there have been more and more micro-green coffee merchants specializing in specific countries. Besides the major specialty coffee countries like Brazil, Panama, Costa Rica, Ethiopia, Guatemala, and Indonesia, those specializing in Colombia, East Timor, India, Thailand, Myanmar... have also gradually appeared on the market. Although these types of green coffee merchants have fewer varieties than large green coffee merchants, they have closer relationships with producers and will actually fly to the origin to visit estates and cup the beans. Perhaps the prices of these types of green coffee merchants are not as attractive as large bean merchants, but relatively, it's less likely to encounter problems.

This batch of beans is an item from C Company, a green coffee merchant specializing in Colombia. According to the green coffee merchant's flavor description, this washed coffee has jasmine floral notes, chocolate, caramel, appropriate acidity and texture, and the variety is Caturra. According to Michael Sheridan's Colombia Caturra vs Castillo experiment presented at the SCAA annual meeting the year before last. When cupping 32 Caturra coffees, the most common flavor descriptions were moderate acidity and texture, chocolate, caramel sweetness. Herbal, citrus, and cherry aromas. Cupping scores ranged around 82-85 points.

This roasting batch was 500g, first taking 100g sample to estimate the defect ratio. The green beans had full moisture content, firm texture, and fresh blue-green color. Defective beans were about 4g, mostly broken beans, sheep hoof shells, and some underdeveloped immature seeds. No fully black, foreign objects, or mold. According to the green coffee merchant's notice, this batch was packaged in small quantities, so some visible defective beans were picked out during packaging.

The bean-in temperature was set at 170°C, the temperature return point was at about one minute and 99.5°C, the heating rate was normal. Due to high moisture content, it took more time for dehydration, with the goal of dropping the beans at the end of first crack. Roasting time was about 9 minutes and 10 seconds, with a drop temperature of 210°C. After roasting, the weight was about 406g.

After resting for 24 hours before brewing, 15g of coffee after grinding revealed a very classic Colombian aroma of acidity and sweetness - apple, cinnamon, nuts, caramel. Brewing with 210cc of 92°C water extracted about 170cc. The wet aroma had spiced apple notes. Upon tasting, there was a rich jasmine fragrance, with flavors between peach and apple. The fruit acidity was not strong but noticeable, with high sweetness and a chocolate aftertaste. Using 20g ground to extract 50cc espresso, the jasmine floral note was not obvious but noticeable. However, because it was only 24 hours after roasting, there was still some harshness that hadn't completely dissipated. The chocolate sweetness in the aftertaste was quite good. It reminded me of a Huila EP Senor Ninfa Perdomo Sosa (70% caturra + 30% castillo) from green coffee merchant P last year. The difference was in the softness and details of the acidity.

This is a versatile bean that can be used for pour-over single origin, or blended with beans from other regions for blends, but it's somewhat monotonous for SOE, and the crema texture cannot be described as delicate.
