Looking For Inspiration? Try Looking Up High Altitude Arabica Coffee Beans

High Altitude Coffee

High altitudes are perfect for coffee production due to their unique conditions. The mountainous terrain and particular climate conditions permit an extended maturation period that creates coffee with a rich and complex flavor profile.

The characteristics of the soil on which coffee is grown also play an important role in its taste. This is especially relevant for volcanic soils that produce full-bodied brews with chocolate and nutty notes.

Cooler Temperatures

The climate is a key factor in determining the flavor and quality of coffee. While all coffee grows in the tropics, the most highly sought-after varieties of arabica beans grow best in mountainous regions that extend across the globe known as the coffee belt. The climatic conditions found in these mountainous areas with frost-free tropical climate, moderate rainfall and plenty of sunshine, create the perfect growing environment for coffee.

The ideal temperatures for arabica plants are between 16 to 23 degrees Celsius which is significantly less than the temperatures required to grow robusta. Coffee plants that are exposed to temperatures outside of this range are less productive and less desirable flavor attributes.

Higher altitudes provide cooler climate, allowing the plant to mature slowly and the beans to ripen over time. This allows for the development of complex sugars that are essential to coffee's distinctive flavor and aromas. It also reduces the amount of water present in the coffee bean, which results in dense (hard) beans with more intense flavor characteristics.

In addition to the cold temperatures, a mountainous cultivation site has soil that is rich in nutrients. This is crucial because nutrient-rich soils offer a healthier environment for healthy and flourishing arabica plants that yield high-quality coffee beans. A well-draining soil is also important for arabica plants because it keeps the roots from becoming saturated, which can lead to illnesses and diseases.

A high altitude location is also less prone to being affected with pests and disease. This is especially true for the coffeeberry borer, a pest which can cause significant damage to crops in low elevations.

The only alternative coffee that can be competitive in terms of quality at higher altitudes than arabica is robusta. Robusta is resistant to pests, and thrives in warmer climates where arabica struggles to thrive. However, the flavor of a robusta coffee is less distinct than that of an arabica. Although arabica is more abounding at higher altitudes than robusta, consumers should still choose a blend or single origin that has both varieties when searching for high-altitude arabica.

Well-Draining  light roast arabica coffee beans

In contrast to Robusta coffee plants that thrive in warmer climates and lower elevations arabica coffee plants prefer cooler temperatures and higher altitudes. These conditions allow the beans to age more slowly, giving them a richer body and a more complex flavor profile.

The unique conditions that make high-altitude farming ideal for arabica coffee plants lead to the production of top quality beans that are sought-after by specialty roasters and consumers. This is because these conditions are conducive to the plant's health and productivity.

To avoid the spread of diseases like rot coffee plants require soil that drains well. A well-draining, airy soil is also better in absorbing nutrients. These factors, along with the cooler temperatures and less direct sunlight characteristic of high-altitude cultivation will result in an energizing and delicious cup of coffee.

Another key factor that contributes to the exceptional taste of high-altitude arabica coffee is the lower oxygen levels which are common in these regions. The lower oxygen levels make the plant more robust and allows it to grow strong roots that enhance the capacity of the plant to absorb nutrients from soil.

Around the globe, the majority of arabica coffee is grown at altitudes of up to 6,500 feet in subtropical regions known as the bean belt. These regions are located close to the equator and have an arid climate that is conducive to coffee plants. However, they also maintain high elevations that are suited to the cultivation of gourmet Arabica beans.

If you want to cultivate your own high-altitude arabica coffee at home, you should first acquire a healthy, mature green arabica seedling from a nursery that is specialized in the cultivation of this species. You must ensure that you have the proper equipment to tackle the challenges of high-altitude coffee cultivation. This includes shade cloths, or a greenhouse to protect the plant from sun. Then, you need to fertilize your arabica with a nitrogen-rich compost that's also high in magnesium, calcium and sulphur. You should water your plant sparingly until spring. This will encourage the development of fruit and flowering which will begin in late winter or the early spring.

Robust Root Systems

Arabica beans are sought-after because of their delicate and complex flavor that can include hints of fruit, chocolate and even flowers. This unique flavor profile can only be achieved when high-quality arabica beans are grown under the specific conditions required by the plant. High altitudes and cooler temperatures are essential to these cultivation conditions, as they help to slow down the plant's growth rate and permit it to produce more complex sugars. These sugars are the reason for the complex and subtle flavors that arabica is famous for.

The higher altitudes at which arabica beans are grown provide the necessary conditions for plants to grow strong root systems that are able to better absorb nutrients from the soil. These strong roots are crucial to the health of the plant and are essential to its ability to produce coffee cherries that are sweet, ripe and delicious.

As opposed to arabica Robusta (Coffea canephora) can survive in lower-altitude climates and is typically grown at 600-2,500 feet above sea level. However, this lower elevation results in the plants producing a more bitter and less desirable coffee. Robusta is often used as a filler in blends of coffee and instant coffee due to its low cost and resistance to pests.

The plants at higher altitudes are more susceptible to climate change, but careful cultivation by farmers will ensure that the crop will thrive in a constantly changing world. Other environmental factors like oxygen levels and temperature can affect the quality of coffee.

These environmental factors include soil quality as well as drainage, water availability, sunlight intensity, and duration, agroforestry, harvesting strategies, postharvest processing, and harvesting practices. The combination of these factors is crucial in determining the final physical and biochemical cup quality attributes of coffee.

Sustainable Cultivation

The coffee plant requires special conditions for cultivation, especially at higher elevations. It is a delicate plant which is susceptible to diseases and pests.

High altitude cultivation provides many benefits that are sustainable to farmers, including superior taste potential and less environmental impact. These unique aspects make for the distinct taste profiles of coffee beans produced at high altitudes, making them extremely sought-after by discerning coffee drinkers and cultivators who specialize in this type of cultivation.

High altitude coffee has a slower growth rate, which results in a richer flavor and more complex sugars. Slower growth allows plants to focus more energy on reproduction, resulting in more mature coffee beans with better quality and more intense flavors.

In addition, higher elevations typically have better drainage, which is important for the health of coffee beans. This ensures a more even spread of nutrients across the ground, and lessens the chance of developing diseases such as root rot. Therefore, coffee that is grown at high altitudes is more likely to have consistent flavors and stronger aromas that are not diminished by the presence of excessive moisture.

Many high-altitude coffee producers employ shade farming techniques that not only protect biodiversity in the rainforest ecosystem, but also enhance the quality of the coffee. This is because the shade-loving coffee plant is able to benefit from the microclimate created by the trees around it, which slows down the growth rate and produces a more balanced, round flavor.

Additionally, shade-grown coffee can be harvested more consistently, which reduces the chance of illness and insect infestations, which are an important issue for lower altitude growers. Shade-grown coffee can also be more sustainable in the environmental sense, since it reduces the use of herbicides and pesticides that can negatively impact wildlife and reduce soil quality.

There are some notable examples of high-altitude coffee that is produced under these unique and sustainable conditions. Geisha is a rare variety with elongated beans and floral notes like tea, as well as notes of tropical fruits, citrus, and jasmine. Another example is Batian, a hybrid that combines resistance to coffee berry diseases and leaf rust, with high productivity and yield.
