Discovering Tanzania's Premium Coffee

When you think of African coffee-producing regions, which countries come to mind? Is it Ethiopia, the birthplace of coffee? Kenya, known for its pleasant coffee fruit acidity? Or Rwanda, famous for its floral and fruity coffee aromas?

Tanzania is a typical East African country, bordering Kenya and Uganda to the north, Malawi, Mozambique, and Zambia to the south, and Rwanda and Burundi to the west. When discussing Tanzanian coffee, the coffee produced in the Kilimanjaro region cannot be overlooked. Located in northeastern Tanzania, it is Africa's highest mountain range. As early as 1893, missionaries introduced Bourbon variety coffee for cultivation. The extreme and unique climate conditions are a treasure for growing coffee. Today, coffee from the Kilimanjaro region is absolutely Tanzania's best representative, accounting for 75% of Tanzania's coffee production.

You might ask, what are the superior or special characteristics of Kilimanjaro coffee's growing conditions? This is because Kilimanjaro is not only Africa's highest mountain range but also a high mountain formed after volcanic eruptions, making it the world's second-largest volcanic crater. It's important to know that volcanic ash soil provides excellent nourishment for cultivating coffee beans. The fertile volcanic soil of Kilimanjaro's high mountains is weakly acidic with good drainage, and the combination of climate and geology allows coffee flavors to develop exceptionally rich.

Additionally, Africa often gives people the impression of being hot and dry year-round. This is actually a big misconception. Take Kilimanjaro as an example: while mountain temperatures can reach up to 59°C, the summit can have perennial snow reaching -34°C, thus Kilimanjaro is also known as the "Equatorial Snow Peak." In terms of rainfall, river valleys receive 800 to 900 millimeters annually; the mountains are cool and rainy, with annual precipitation reaching 1600 to 1800 millimeters on windward slopes. The special characteristics of coffee flavor grown in the climate and geographical environment provided by this "Equatorial Snow Peak" can be imagined.

Tanzania's Peaberries: A Precious Rarity

Tanzania's peaberries absolutely add brilliance to Tanzanian coffee production. You might ask: What are peaberries? What are flat beans? Aren't coffee beans just beans? Is there a difference between round and flat? Here, I need to supplement some information on this topic.

First, the true form of coffee beans is the drupe inside coffee cherries - they are seeds, a type of plant. Normally, a coffee berry contains two seeds divided in half - what we call flat beans. Scientifically, these are called flat beans.

Peaberries are actually a variant of coffee beans. Scientifically also known as "caracol" or "caracolillo" in Spanish, meaning small snail. Botanically, there are two possible reasons for the appearance of peaberries: 1. Uneven pollination, 2. Uneven nutrition during growth. Instead of dividing into two seeds, the internal seed of the plant did not split, thus presenting a complete oval-shaped single peaberry. How common is this situation? Generally, peaberry production is about 1/50 of flat bean production. In other African coffee-producing countries like Kenya, peaberries also appear. But in Tanzania, only about 5% to 10% of fruits in local coffee production develop into peaberry form. Moreover, peaberries are smaller than flat beans and are separated from flat beans during processing through screening, independently graded and selected for sale. Compared to flat beans, peaberries are very rare and precious.

In terms of flavor, are peaberries better, or are flat beans better? There's really no conclusion on this, and many people still discuss this issue today. Indeed, the appearance of peaberries is a defect in coffee cherry growth, but some believe that all nutrients are stored in the smaller peaberry, concentrating more nutrients than regular flat beans, making the flavor more prominent, sweeter and richer, which is not unreasonable.

The Unique Flavor Profile of Tanzanian Coffee

If Ethiopian coffee's floral aroma is stunning and Kenyan coffee is known for its pleasant fruit acidity, then how should Tanzanian coffee be described?

Tanzanian coffee gives people the feeling of being very sweet, smooth, and easy to drink, and it wins with its non-acidic, mild, and varied chocolate sweetness, often making people think it's a cup of high-quality Colombian coffee.
