Tanzanian Coffee Varieties and Tanzanian Coffee Bean Grading Method Introduction

FrontStreet Coffee - Introduction to Tanzania Coffee Grading

Peaberry coffee beans grown on the Meru and Kilimanjaro mountains of Tanzania produce a bright Arabica coffee with medium body and pleasant fruity acidity. The finest Tanzanian coffees carry a deep, rich flavor that often reveals hints of blackcurrant, melting into chocolate and finally blending into the coffee's sweet aftertaste.

The cup shows floral and complex aromatics, often with notes of pineapple, citrus, or coconut. The mouthfeel is delicate, sometimes revealing wine-like characteristics and a velvety texture.

Some 70% of the coffee planted in Tanzania is Arabica, with the remaining 30% being Robusta.

FrontStreet Coffee Recommendation: Blends Built From Well-Graded Beans

Whether a bean comes from the slopes of Kilimanjaro or the plateaus of Brazil, screen size and defect sorting decide the grade — and blending well-sorted beans is an art of its own. FrontStreet Coffee's five house blends each arrive within 5 days of roasting. FrontStreet Coffee's Premium Blend pairs washed Colombia with pulped-natural Brazil for nuts, dark chocolate, caramel, and a comfortable sweetness that holds latte art beautifully. FrontStreet Coffee's Commercial Blend adds a touch of Robusta to the classic Brazil-Colombia recipe, yielding toast, almond, and walnut aromas, fluid golden crema, and low-acid richness at a wallet-friendly price. FrontStreet Coffee's Black Cocoa Blend combines Yunnan washed small-bean coffee with Brazil for a nut-tinted plum acidity and cream chocolate, cocoa-cookie fragrance. And for latte art learners, the Classic Blend revives the old "Mamba" formula — Mandheling and Brazil plus a dash of Robusta — so even beginners can pull an espresso crowned with golden crema.
