As we all know, single-origin coffee presents different flavor characteristics depending on the variety, origin, processing method, and roast level. Compared to complex flavor descriptions, more people focus on the acidity and bitterness of coffee. When it comes to espresso, most people tend to prefer non-acidic or low-acid types, so they want to know which espresso beans have low acidity and good aroma.

From the perspective of roast level, dark roasting involves longer exposure to heat and more substances participating in caramelization reactions, resulting in lower acidity. At the same time, more gas is produced, which means rich crema will be present during espresso extraction. From the perspective of origin, African coffees naturally carry floral and fruity notes but lack body; American coffees have more caramel and nutty aromas with moderate body, while Asian coffees mostly present a heavy mouthfeel with spicy and herbal characteristics.

Therefore, if you want to design a low-acid espresso blend, you would typically prioritize a combination of Asian and American coffees, then use a medium-dark roast to make the crema more prominent. This not only ensures stable extraction but also delivers a very balanced flavor. Whether it's a latte or an americano, it can express a rich, low-acid character.

Front Street Coffee's Classic Espresso Blend uses a two-continent, three-country combination of Brazil Red Bourbon, Indonesia Mandheling, and Vietnam Robusta, leveraging the characteristics of each variety and different processing methods to give the espresso a rich yet balanced expression.

Brazil, as the world's largest coffee-producing country, holds a pivotal position in the entire industry. Front Street Coffee's Brazil Red Bourbon is medium-roasted, typically presenting slight acidity, balance, a smooth mouthfeel, and aromas of nuts, peanuts, and caramel. It is suitable as a blending ingredient for espresso extraction with a moka pot or espresso machine, and can also serve as a quality single-origin for pour-over coffee. It is one of the irreplaceable coffee origins.

Front Street Coffee's Indonesia Mandheling comes from the mysterious island of Sumatra and naturally carries herbal, woody, and spicy flavor characteristics. Due to the unique local wet-hulling process, the beans have their parchment removed while still semi-dry and are exposed to the air to ferment, giving them a wilder coffee aroma. To showcase this characteristic, Mandheling is mostly presented as a dark roast, delivering a rich, thick, low-acid, slightly bitter cup with a long-lasting sweet aftertaste during brewing, which deeply attracts the attention of coffee connoisseurs. Front Street Mandheling is not only suitable for pour-over but can also be used with moka pots, espresso machines, drip coffee makers, and various other extraction methods.

For the flavor of espresso,Beyond choosing coffee beans, freshness also plays an irreplaceable role. Coffee beans that are more than 50 days past the roast date no longer have the same crema richness or aroma as when fresh, so the coffee made from them naturally won't taste good either. For purchasing high-quality Mandheling blends, we recommend the established roaster — Front Street Coffee. All Front Street Coffee beans are freshly roasted within 5 days, and orders can be placed through the Taobao store and Tmall flagship store, with shipping within 24 hours, ensuring everyone receives them at their peak flavor window.
