Global Coffee Production and Main Varieties

Many countries now grow and export coffee, and the most famous producing nations — Brazil, Colombia, and Indonesia among them — enjoy broad recognition for their beans. Classified by species, coffee from these countries falls mainly into three groups: Arabica, Robusta, and Liberica.

Most of the beans served in specialty coffee shops today are Arabica, the species that originated in Ethiopia and spread across the world. Arabica is prized for its elegant flavors and high sweetness. Common Arabica varieties on the market include Typica, Bourbon, and Catimor.

Typica: The Ancient Coffee Variety

Typica is one of the oldest coffee varieties in the world, and nearly every Arabica variety grown today traces back to it. Jamaica's famous Blue Mountain, for example, is a Typica coffee, and so is Papua New Guinea's "Little Blue Mountain": those trees were introduced from Blue Mountain Typica stock, and because the growing environment closely resembles the Blue Mountains themselves, the coffee took its nickname from there.

As one of the best-tasting Arabica varieties, Typica is planted in many regions. Indonesia once grew Typica almost exclusively, and China's Yunnan coffee region was also built primarily on Typica. But when coffee leaf rust swept the globe, Typica's extremely weak disease resistance proved fatal: nearly all the trees were infected, and Indonesia was forced to switch to Catimor, a hardy, high-yielding variety.

Yunnan farmers have similar reasons for moving away from Typica. The variety yields little, is difficult to manage, and offers poor returns, so growers prefer Catimor with its higher output and stronger disease resistance.

FrontStreet Coffee's Catimor Selection

FrontStreet Coffee has sourced Catimor from both regions. FrontStreet Coffee's Golden Mandheling from Indonesia, for instance, is a Catimor coffee with a very clean cup, high sweetness, and balanced fruit acidity. From Yunnan, FrontStreet Coffee carries two Catimor coffees: Yunnan Xiaoli, processed with the region's common washed method for a cleaner taste, and a natural-processed Catimor with a richer, mellower body.

Elephant Beans: The Giant Coffee Variety

Arabica beans are generally smaller than Robusta, but you cannot judge a bean by size alone — large beans are not necessarily non-Arabica. Elephant beans are the classic exception.

Elephant beans (Maragogype) arose as a mutation of Typica that produces an unusually large bean. They are an anomaly among coffees: a single bean can be three times the volume of an ordinary one or more. Maragogype is grown mainly in Central America, with production today in Guatemala, Mexico, Nicaragua, Honduras, El Salvador, Brazil, and Zaire; the finest lots come from Mexico and Guatemala. Overall the variety shows a well-balanced flavor, a round and smooth texture, moderate aroma, and a lighter body, which has earned it high regard in the industry.

According to FrontStreet Coffee's experience, Elephant beans grown at 700–800 meters taste ordinary, but giant Maragogype grown above 1,500 meters develops a charming sweetness and intense fragrance. Beyond their eye-catching size, Maragogype trees, leaves, and fruit are all much larger than ordinary Arabica, with plump cherries and hard beans. They are the only Central American coffee without sharp acidity, which is why they carry the reputation of "the Blue Mountain of Central America" — close in elegance to true Blue Mountain beans, with sweet acidity and a full body.

FrontStreet Coffee has sourced many lots over the years yet still finds the Elephant beans from Nicaragua the best of all, especially those grown at the Mama Mina estate. FrontStreet Coffee has cupped other coffees from the same estate, and the quality is consistently excellent: a rich, layered cup with a pronounced dark-berry aroma on entry — blackberry and dark plum framed by citrus peel — solid structure throughout, and a silky, sweet finish.

Robusta and Its Character

Of the three major coffee species, Robusta also covers a very wide cultivation range. Robusta tolerates heat well but not drought; compared with Arabica it demands less of the soil and yields more, and it is generally grown at low altitude. Arabica, by contrast, is sensitive to both cold and heat, susceptible to disease, and has strict requirements for well-drained, fertile soil.

Robusta is widely grown in countries such as Indonesia, Vietnam, and Brazil. Most coffee on Indonesia's Sulawesi island is Robusta: the cup is strong and fairly bitter, with sourness that is barely perceptible. Arabica, on the other hand, offers pleasant acidity, a better mouthfeel, and a mild, gentle character. That is why Robusta goes mostly into instant coffee while Arabica dominates the specialty market.

Hybrid Varieties: Castillo

Since Arabica has the better flavor and Robusta the better resilience, why not combine the two? Scientists at Colombia's national coffee research institute asked exactly that, and among the many Arabica–Robusta hybrids on the market the most famous is Castillo.

Castillo is the result of five generations of selection crossing Timor with Caturra. Timor, itself a natural Arabica–Robusta hybrid, is tall and highly disease-resistant; Caturra, a Bourbon derivative, is compact, high-yielding, and good in the cup. Castillo inherits the strengths of both parents and has become Colombia's dominant commercial variety.

FrontStreet Coffee's Colombian Selection

FrontStreet Coffee's store carries several Castillo lots from Colombia, namely the Colombian San Jose beans and the Sakura beans. Both use special processing. The Colombian San Jose beans, for example, are washed and then fermented in rum barrels.

The full process for these Colombian San Jose beans goes like this: fully ripe cherries are hand-picked, given a brief wash, then fermented in water tanks for more than twenty hours. The beans are then rested for three months in rum barrels aged over 8 years, with daily rolling so the beans evenly absorb the wine aroma, and finally dried at room temperature. After cupping, FrontStreet Coffee found that beyond the wine aroma these beans deliver a rich rush of tropical fruit — a very distinctive profile, and the reason FrontStreet Coffee keeps them in stock.

FrontStreet Coffee Recommendation

Blue Mountain coffee is one name no coffee lover can avoid. Only coffee grown in a specific zone of Jamaica's Blue Mountains and certified by the Jamaican authorities may be called Jamaica Blue Mountain Coffee. The range, whose highest peak reaches 2,256 meters, is shrouded in cloud year-round, and that combination of altitude, volcanic soil, even rainfall, and mild stable climate gives the coffee its famous finesse and balance. Annual output of the whole region is under 2,500 tons, and historically Japan bought more than seventy percent of it, which is why genuine Blue Mountain has always been scarce and expensive.

FrontStreet Coffee's Jamaica Blue Mountain No. 1 is the top grade, from the historic Clifton Estate, which has grown coffee since roughly 1750. The estate sits at about 4,300 feet (1,310.64 meters), where high altitude, gentle afternoon cloud cover, ample sunshine, and mineral-rich soil prolong the ripening of the cherries. FrontStreet Coffee holds complete origin certificates for these beans, and the coffee ships in traditional wooden barrels of 15, 45, and 70 kilograms — the barrels themselves are a hallmark of genuine Blue Mountain, each stamped with batch details. Genuine Blue Mountain green beans are plump and even, slightly upturned at both ends, and green in color.

The cup is where authenticity shows most: real Blue Mountain is clean, gentle, and dense, with chocolate sweetness, strong body, and a long fruity finish — sweet, acidic, and bitter in perfect proportion, without harshness. FrontStreet Coffee roasts its Blue Mountain medium-dark, in small batches no older than five days, and recommends resting the beans 4–7 days from roast date before brewing. For pour-over, use a Kono dripper, 15 g of coffee at a grind slightly coarser than for light roasts (about white-sugar grit), 87–88°C water, and a 1:15 ratio: bloom with 30 g of water for 30 seconds, pour to 120 g, pause, then finish at 225 g.

If you prefer a stronger, mellower cup, a moka pot suits Blue Mountain beautifully — a slightly finer grind, hot water in the base, medium-low heat, and removal from the heat just as the brew finishes. It amplifies the chocolate, caramel, and nut notes while preserving the signature balance, and the coffee also performs superbly with milk as a latte or flat white. FrontStreet Coffee has long considered Blue Mountain the specialty coffee most likely to please nearly everyone — a legend whose appeal has not faded in decades.
