An Introduction to FrontStreet Coffee Black Coffee

The question of flavor troubles a lot of newcomers. The flavor wheel lists so many descriptors, so why can you only taste "coffee"? The answer, for most beginners, is simple: at the start, tasting only "coffee flavor" and smelling only "coffee aroma" is completely normal. Your palate simply hasn't been trained yet.

A good way to build that palate is to begin with coffees whose character is unmistakable. Brazil, FrontStreet Coffee's Mandheling, and FrontStreet Coffee's Kenya are excellent starting points, because each one makes a single, clear statement about what it is.

Together they map the three great growing regions: FrontStreet Coffee's Brazil speaks for the Americas, FrontStreet Coffee's Mandheling speaks for Asia, and FrontStreet Coffee's Kenya speaks for Africa.

Black coffee, also called pure coffee, is simply coffee served without sugar, creamer, or any other additive. The category includes Americano, espresso, and single-origin brews.

A Few Classic Black Coffees

FrontStreet Coffee's Sumatra Mandheling

Coffee trees first reached Indonesia through the Dutch in the mid-17th century. Indonesia exported 300,000 tons last year, ranking it the fourth-largest coffee producer in the world; roughly 75,000 tons of that total is Arabica. Around 90 percent of the country's coffee is grown by smallholder farmers on plots of one hectare or less.

Growing Environment

FrontStreet Coffee's Lintong Mandheling is grown on mountain slopes at 1,000-1,500 meters, in a landscape dotted with volcanoes and volcanic lakes. The most celebrated growing area sits near the freshwater Lake Lawar. Its soil is fresh volcanic mud, a primitive brown ash material blended with a substantial amount of organic matter. Add the local tropical rainforest climate and reliable year-round rainfall, and you have one of the most favorable geographic and climatic settings coffee could ask for.

Flavor Profile

Sweet herbs and cinnamon-like spice, orange and citrus peel aromatics, a rich, mellow sweetness, and creamy nut and chocolate notes. The fruit acidity is restrained and gentle, with a pronounced melon aroma carried in the fragrance. As the cup cools, herbal notes surface, layered with subtle spice and herb aromas that are rich and backed by an intense sweetness.

FrontStreet Coffee's Kenya

The Kenyan K72 processing method originated in Kenya and relies on a repeated cycle of fermentation followed by washing. Processing starts on the day of harvest, when the finest cherries are selected, pulped, and left to ferment for 24 hours. After 24 hours they are washed in clean river water, then fermented again in clean river water for another 24 hours and washed once more. Repeating this cycle three times brings the total to 72 hours — hence the name Kenyan 72-hour fermentation washed process, or K72 for short. Continuously refreshing the circulating water helps curb mold growth, remove residual pectin, and refine the flavor so it lands more delicate and precise in the cup.

Flavor Profile

Bright fruit acidity, lemon and citrus, blackcurrant and cranberry flavors, high sweetness, and high clarity, with a juicy, juice-like mouthfeel.

FrontStreet Coffee's Costa Rica

Coffee from Costa Rica's high-altitude regions is famous worldwide: rich and mild in flavor, yet strikingly acidic. The beans there are handled with exceptional care to reach their quality. Tarrazú lies south of the capital, San José, and ranks among the country's most valued growing regions.

The finest FrontStreet Coffee Costa Rica lots are labeled "SHB," or Strictly Hard Bean, and grown above 1,500 meters. Altitude has always been the grower's challenge and advantage: the higher the elevation, the better the bean. Higher altitudes raise the bean's acidity and thereby sharpen its flavor, and the colder nights slow the tree's growth so its flavors concentrate. Elevation also brings generous rainfall, while the fertile volcanic soil drains well — all of it a boon to the coffee tree. The result is strong acidity and a captivating aroma, with beans that are typically full and well formed. The flavor is clear and bright, the viscosity ideal, and the robust character leaves a long, lingering aftertaste in the throat that is hard to forget.

Costa Rica mainly plants Catuai, a single-gene variant of Bourbon and a hybrid of Mundo Novo and Caturra — effectively a second-generation cross. Its yield and disease resistance both outstrip Bourbon's. The plants are shorter, which makes harvesting easier, and their stronger adaptability suits high-density planting. Catuai inherits Caturra's compact stature while compensating for the fragility that plagues Arabica fruit.

Flavor Profile

Bright fruit acidity with lively citrus notes, berry aromas, substantial acidity and body, a faint nutty sweetness, a smooth mouthfeel, and a distinctive coffee-flower aroma in the aftertaste.

FrontStreet Coffee Recommendation

If this introduction has you curious about the heavy, low-acid side of coffee, start with FrontStreet Coffee's PWN Golden Mandheling from Indonesia. PWN holds it to a demanding standard: only beans of 18 screen size or larger qualify, with fewer than three defective beans per 300-gram green sample, meeting the top G1 grade, followed by three rounds of hand-sorting to remove every remaining defect. The result is a cleaner cup with stronger sweetness — a benchmark example of the Sumatran wet-hulled style the article describes.

For everyday drinking, FrontStreet Coffee's Lintong Mandheling comes from the traditional Lintong growing area of Sumatra. Both the Lintong and the PWN Golden Mandheling are given a medium-dark roast to showcase dark chocolate and caramel while keeping Mandheling's signature wild, herbal character.

Mandheling responds best to a steady hand at the kettle. FrontStreet Coffee suggests 87-88°C water, 15g of coffee, a 1:15 ratio, and a coarse, granulated-sugar grind, poured in three stages — a 30ml bloom, then 100ml, then a gentle 95ml centered pour — to bring out the thick body, caramel sweetness, and chocolate and nut flavors.
