As the specialty coffee market grows, specialty coffees have multiplied, and the market now overflows with high-quality beans that can be genuinely dazzling. FrontStreet Coffee offers more than 50 varieties for sale, plus many more that haven't been listed. FrontStreet Coffee buys green beans from suppliers and roasts them fresh in-house. After a series of quality-control evaluations, including cupping and brewing, only beans that at least express the basic flavor characteristics of their growing region and carry no unpleasant tastes are released to the public. Whether or not a coffee is ultimately listed, FrontStreet Coffee publishes its cupping information online — origin, processing method, variety, roasting recommendations, cupping reports, and a series of articles — for every coffee enthusiast to review.

How to Choose Coffee Beans That Suit Your Taste

Many beginners struggle to choose, wanting to try every variety. So FrontStreet Coffee has put together a simple guide anyone can use to pick a favorite.

Regional Flavor Characteristics:

Ethiopia, Kenya: Bright, citrusy and lemony fruit acidity.

Guatemala: Nuts, mild fruit acidity.

Panama: Rich floral notes, mild fruit acidity.

Colombia: Nuts, cocoa, mild fruit acidity.

Costa Rica: Nuts, mild fruit acidity, noticeable sweetness.

Brazil: Nuts, cocoa, creamy mouthfeel.

Honduras: Rich mouthfeel, neither astringent nor acidic, high body and aroma.

Indonesia: Spices, herbal notes, high body.

Yunnan: Herbal notes, mild fruit acidity, neither acidic nor astringent, medium body.

Jamaica Blue Mountain: A perfect balance of sweet, sour, and bitter.

Hawaii Kona: Mild fruit acidity, high body.

Processing methods grow more innovative every year, with many specialty approaches emerging — anaerobic fermentation, enzyme washing, and more. Among them, though, three remain the most conventional: washed, natural, and honey. Here's how those three traditional methods shape flavor:

Washed Processing Method:

FrontStreet Coffee believes washed coffee has more pronounced acidity, better cleanliness, a medium mouthfeel, and the most consistent green bean quality. African regions often use washed processing, which lets their beans express bright, citrus-like acidity.

Natural Processing Method:

FrontStreet Coffee believes natural processing lets the cherries dry intact, so the beans mature naturally inside the fruit without interference from the outside environment. Naturally processed beans therefore amplify their inherent flavors, with rich body, intense flavor, and noticeable sweetness.

Honey Processing Method:

FrontStreet Coffee believes honey-processed beans have superior flavor, with balanced acidity and sweetness. Like natural processing, honey involves sun-drying, so the beans' inherent aroma is amplified too, along with a rich body.

Flavor Performance of Different Roast Levels:

Light Roast: Rich fruity notes, with sweet-and-sour floral and fruity aromas, a clean and refreshing mouthfeel, and no viscous sensation.

Medium Roast: Nutty notes, primarily caramel, cocoa, and malt aromas, with a smooth mouthfeel and slight viscosity.

Dark Roast: Slight chocolate bitterness, low acidity, rich caramel aroma, with spice, woody, and charcoal notes, a smooth mouthfeel, rich body, and no astringency.

FrontStreet Coffee Recommendation

If Colombia's nutty, cocoa-accented, mildly acidic profile from the guide above is what you're after, FrontStreet's washed Huila beans are the ideal starting point. From Colombia's most celebrated specialty region, they are medium-dark roasted to emphasize dark chocolate and nutty sweetness, with moderate crema and a full body — excellent as a pour-over or French press and equally at home in a moka pot or espresso machine for an Americano or latte.

For a brighter, more fruit-driven Colombian cup, FrontStreet's El Diviso Sidra is a competition-caliber variety grown at 1,650-1,800 meters and processed with a double anaerobic natural method, then roasted medium-light to preserve its native fruit. Its dry aroma carries jasmine and citrus, while the cup shows passion fruit, blueberry, grape, and apricot juice, bright and gentle acidity, a touch of spice mid-palate, and a lingering cocoa finish — suited to pour-over, espresso SOE, and cold drip. If you have a home espresso machine or moka pot, FrontStreet's Signature Blend pairs Brazil's creamy nuttiness with Colombia's dark chocolate bittersweetness and pulls fine golden crema, making rich, smooth lattes that are especially beginner-friendly.
