What is the only U.S state that produces coffee?

In this brief article, we will provide you with the answer to the question: “What is the only U.S state that produces coffee?”, and discuss the factors that impact coffee growing. 

What is the only U.S state that produces coffee?

Coffee can only be produced commercially in two states in the United States: Hawaii and California. However, Puerto Rico, a US territory, has a booming coffee industry.

Experimentation with coffee cultivation is also taking place in Georgia and Santa Barbara, California. 

Approximately 90% of coffee eaten in the United States is imported, primarily from South America. In addition, the country buys raw coffee beans, processes them into various coffee products, and sells them to the international market.

Coffee production in California

Despite the fact that the climate in California is not conducive to coffee growing, local farmers have invented an irrigation system to assist coffee beans in thriving. California beans are in great demand across the country, particularly because the general public is curious about how they taste. 

Coffee production in Hawaii 

There are several coffee farms on the island of Hawaii. The state is well-known for its Kona coffee. The Kona “coffee belt” is roughly 2 miles wide, and is distinguished by black, volcanic soil, provides ideal conditions for the coffee tree and yields some of the world’s best coffee beans. 

Ka, Puna, and Hmkua are other places in Hawaii where coffee is farmed on a considerable basis. Coffee is harvested in Hawaii all year, with the largest output occurring between late summer and early spring. 

Coffee has been grown in Hawaii since 1813. However, John Wilkinson imported known coffee plants from Brazil in 1925. These plants were planted in Manoa Valley but did not survive. 

Later, some trees were planted on the island, primarily by missionaries who visited the region. Reverend Samuel Ruggles brought coffee to the Kona District in 1828, which proved to be the most successful place for coffee cultivation.

What are the factors that impact coffee growing and quality?

The first element to consider before beginning the coffee plantation is the location. This is due to the fact that the plant may not develop properly if cultivation is carried out in places that do not allow for complete development.


The coffee plantation must adhere to certain climatic criteria in order for the culture to flourish in a healthy manner. Temperatures ranging from 18ºC to 23ºC are good for culture, whereas temperatures exceeding 30ºC can severely impede growth.


The best rainfall regime for commercial cultivation is in the range of 1200 mm to 1500 mm per year. It is critical that precipitation reaches, above all, the vegetative growth and fruiting phases.


Coffee is a plant that is more difficult to cultivate in locations at sea level, and it is recommended that plantations occur in areas between 600 m and 1200 m of altitude.


High and low humidity levels can both be detrimental to coffee growth. High humidity encourages the growth of pests, illnesses, and unfavourable fermentations. Low humidity encourages the presence of some pests and hinders plant growth.


It is suggested that coffee plantations be carried out in flatter regions. As a result, in addition to lowering labour costs, it is feasible to facilitate automation, erosion control, and soil protection.

Soil examination

The great majority of coffee correction and fertilization guidelines call for soil analysis between 0 and 20 cm, and in some cases between 20 and 40 cm. However, it is important to remember that coffee is a perennial plant, which means it grows throughout the year and is subject to yearly and interannual weather fluctuations.

The plant may develop its root system and explore a larger volume of soil in-depth if the soil conditions are suitable. Thus, it is advised that soil analysis be performed at least up to the layer between 40 and 60 cm in order to more effectively rectify fertility problems and allow for further study of the soil.

In terms of soil properties, it must have a minimum depth of one meter and, preferably, not be rocky or extremely sandy, as well as sufficient drainage.


The spacing between coffee seedlings is closely related to the crop’s yield and lifespan. The proper spacing between the plants and the lines allows for lower input costs while also ensuring improved product quality at harvest.

These are some of the features that are crucial for coffee production and the quality of the beans. Check here how to plant coffee.
